Purpose: The diagnosis of auditory processing disorder (APD) is controversial particularly due to the influence of higher order factors of language and cognition on the diagnostic APD testing. As a result, there might be a need for testing for other domains (e.g., cognition) along with conducting the diagnostic APD testing to rule out the influence of other domains. In order to make recommendations on whether cognitive testing is needed along with the auditory processing testing, as a starting point, the current study was conducted to examine the relationship between cognitive abilities and basic auditory processing in young adults. Method: A total of 38 young adults with normal audiometric thresholds between 250 and 8000 Hz participated in this study. They were tested on their executive function, language, processing speed, working memory, and episodic memory components of cognitive testing and tests for temporal fine structure and spectrotemporal sensitivity for auditory processing testing. Results: No significant correlation was found between the cognitive tests and the tests for basic auditory processing in young adults. Conclusions: These findings present contrast to the existing findings in children and older adults where a stronger correlation between cognitive abilities and auditory processing has been found. The current findings suggest that testing for cognitive abilities may not be needed when testing for basic auditory processing in young adults. [ABSTRACT FROM AUTHOR]

Purpose: Verbal working memory is poorer for children with hearing loss than for peers with normal hearing (NH), even with cochlear implantation and early intervention. Poor verbal working memory can affect academic performance, especially in higher grades, making this deficit a significant problem. This study examined the stability of verbal working memory across middle childhood, tested working memory in adolescents with NH or cochlear implants (CIs), explored whether signal enhancement can improve verbal working memory, and tested two hypotheses proposed to explain the poor verbal working memory of children with hearing loss: (a) Diminished auditory experience directly affects executive functions, including working memory; (b) degraded auditory inputs inhibit children’s abilities to recover the phonological structure needed for encoding verbal material into storage. Design: Fourteen-year-olds served as subjects: 55 with NH; 52 with CIs. Immediate serial recall tasks were used to assess working memory. Stimuli consisted of nonverbal, spatial stimuli and four kinds of verbal, acoustic stimuli: nonrhyming and rhyming words, and nonrhyming words with two kinds of signal enhancement: audiovisual and indexical. Analyses examined (a) stability of verbal working memory across middle childhood, (b) differences in verbal and nonverbal working memory, (c) effects of signal enhancement on recall, (d) phonological processing abilities, and (e) source of the diminished verbal working memory in adolescents with cochlear implants. Results: Verbal working memory remained stable across middle childhood. Adolescents across groups performed similarly for nonverbal stimuli, but those with CIs displayed poorer recall accuracy for verbal stimuli; signal enhancement did not improve recall. Poor phonological sensitivity largely accounted for the group effect. Conclusions: The central executive for working memory is not affected by hearing loss or cochlear implantation. Instead, the phonological deficit faced by adolescents with CIs denigrates the representation in storage and augmenting the signal does not help. [ABSTRACT FROM AUTHOR]

Purpose: Traumatic brain injury (TBI) is associated with a range of cognitive-communicative deficits that interfere with everyday communication and social interaction. Considerable effort has been directed at characterizing the nature and scope of cognitive-communication disorders in TBI, yet the underlying mechanisms of impairment are largely unspecified. The present research examines sensitivity to a common communicative cue, disfluency, and its impact on memory for spoken language in TBI. Method: Fifty-three participants with moderate–severe TBI and 53 non-injured comparison participants listened to a series of sentences, some of which contained disfluencies. A subsequent memory test probed memory for critical words in the sentences. Results: Participants with TBI successfully remembered the spoken words (b = 1.57, p < .0001) at a similar level to non-injured comparison participants. Critically, participants with TBI also exhibited better recognition memory for words preceded by disfluency compared to words from fluent sentences (b = 0.57, p = .02). Conclusions: These findings advance mechanistic accounts of cognitive-communication disorder by revealing that, when isolated for experimental study, individuals with moderate–severe TBI are sensitive to attentional orienting cues in speech and exhibit enhanced recognition of individual words preceded by disfluency. These results suggest that some aspects of cognitive-communication disorders may not emerge from an inability to perceive and use individual communication cues, but rather from disruptions in managing (i.e., attending, weighting, integrating) multiple cognitive, communicative, and social cues in complex and dynamic interactions. This hypothesis warrants further investigation. [ABSTRACT FROM AUTHOR]

Purpose: Nonword repetition (NWR) has been described as a clinical marker of developmental language disorder (DLD), as NWR tasks consistently discriminate between DLD and typical development (TD) cross-linguistically, with Cantonese as the only reported exception. This study reexamines whether NWR is able to generate TD/DLD group differences in Cantonese-speaking children by reporting on a novel set of NWR stimuli that take into account factors known to affect NWR performance and group differentiation, including lexicality, sublexicality, length, and syllable complexity. Method: Sixteen Cantonese-speaking children with DLD and 16 age-matched children with TD repeated two sets of high-lexicality nonwords, where all constituent syllables are morphemic in Cantonese but meaningless when combined, and one set of low-lexicality nonwords, where all constituent syllables are nonmorphemic. Low-lexicality nonwords were further classified on sublexicality in terms of consonant–vowel (CV) combination attestedness (whether or not CV combinations in nonword syllables occur in real Cantonese words). Results: Children with DLD scored significantly below their peers with TD. Effect sizes showed that high-lexicality nonwords and nonword syllables with attested CV combinations offered the greatest TD/DLD group differentiation. Nonword length and syllable complexity did not affect TD/DLD group differentiation. Conclusions: NWR can capture TD/DLD group differences in Cantonese speaking children. Lexicality and sublexicality effects must be considered in designing NWR stimuli for TD/DLD group differentiation. Future studies should replicate the present study on a larger sample size and a younger population as well as examine the diagnostic accuracy of this NWR test. [ABSTRACT FROM AUTHOR]

Purpose: The current study examined (a) the relation between morphologically complex word (MCW) use (words containing at least one derivational morpheme such as prefixes and suffixes) and teachers’ ratings of writing quality, (b) average change in MCW use in writing across the school year, and (c) differential change in MCW among students with varying language abilities and linguistic backgrounds including students with developmental language disorders (DLDs) and multilingual learners (MLs). Method: Expository writing samples (writing for the purpose of explaining or educating) were collected in October and May from 824 fifth-grade students, including 109 with DLD and 170 who were MLs receiving English as a second language service. Students’ written responses were coded for the use of MCW. Pearson product–moment correlations and two-level hierarchical linear models were employed to investigate the association between MCW usage and writing quality, as well as increases in MCW usage over the course of the academic year, taking into account the nested structure of students within classrooms. Results: The relation between students’ MCW use and teachers’ writing quality ratings was moderately strong (r = .47). Student use of MCW in expository writing showed significant change from fall to spring across all students. However, the amount of change in MCW use across the school year was significantly lower for MLs (effect size [ES] = .09) and students identified with DLD (ES = .10). Conclusions: The relation between MCW use and teachers’ writing quality ratings highlights the utility of MCW as a written language measure for progress monitoring or assessment. The presence of differential change and potential Matthew effects for MLs and students with DLD substantiates the need for further exploration of instructional components that support the increased use of complex vocabulary.

Purpose: Anomia, or word-finding difficulty, is a prevalent and persistent feature of aphasia, a neurogenic language disorder affecting millions of people in the United States. Anomia assessments are essential for measuring performance and monitoring outcomes in clinical settings. This study aims to evaluate the reliability of response time (RT) annotation based on spectrograms and assess the predictive utility of proxy RTs collected during computerized naming tests. Method: Archival data from 10 people with aphasia were used. Trained research assistants phonemically transcribed participants’ responses, and RTs were generated from the onset of picture stimulus to the initial phoneme of the first complete attempt. RTs were measured in two ways: hand-generated RTs (from spectrograms) and proxy RTs (automatically extracted online). Interrater agreement was evaluated based on interclass correlation coefficients and generalizability theory tools including variance partitioning and the ϕ-coefficient. The predictive utility of proxy RTs was evaluated within a linear mixed-effects framework. Results: RT annotation reliability showed near-perfect agreement across research assistants (ϕ-coefficient = .93), and the variance accounted for by raters was negligible. Furthermore, proxy RTs significantly and strongly predicted handannotated RTs (R² = ~0.82), suggesting their utility as an alternative measure. Conclusions: The study confirms the reliability of RT annotation and demonstrates the predictive utility of proxy RTs in estimating RTs during computerized naming tests. Incorporating proxy RTs can enhance clinical assessments, providing additional information for cognitive measurement. Further research with larger samples and exploring the impact of using proxy RTs in different psychometric models could optimize clinical protocols and improve communication interventions for individuals with aphasia.

Purpose: Shared reading provides preschool-age children with the opportunity to learn novel, low-frequency words. Abundant empirical evidence demonstrates that children can learn the meanings of such words during shared reading, referred to as “semantic learning.” However, less is known about whether children learn the spellings of words during shared reading, referred to as “orthographic learning,” and whether this learning is related to early word reading. The present study tested relations between individual differences in 4- to 6-year-old children’s semantic and, critically, orthographic learning during shared reading and their early word reading skill. Method: In an adaptation of the self-teaching paradigm, children listened to a storybook about novel inventions referred to with nonword names. Children then completed orthographic and semantic choice tests, as well as standardized measures of early word reading and phonological awareness. Results: Individual differences in orthographic, but not semantic, learning during shared reading were related to early word reading, after controls for age and phonological awareness. Conclusions: This study provides a novel test of learning during shared reading, helping to specify the relation between orthographic and semantic learning and early word reading skill. These findings hold implications for theoretical perspectives on relations between learning during shared reading and early word reading, as well as implications for educational practice [ABSTRACT FROM AUTHOR]

Purpose: The present meta-analysis investigated the efficacy of anomia treatment in bilingual and multilingual persons with aphasia (BPWAs) by assessing the magnitudes of six anomia treatment outcomes. Three of the treatment outcomes pertained to the “trained language”: improvement of trained words (treatment effect [TE]), within-language generalization of semantically related untrained words (WLG-Related), and within-language generalization of unrelated words (WLG-Unrelated). Three treatment outcomes were for the “untrained language”: improvement of translations of the trained words (crosslanguage generalization of trained words [CLG-Tx]), cross-language generalization of semantically related untrained words (CLG-Related), and crosslanguage generalization of unrelated untrained words (CLG-Unrelated). This study also examined participant- and treatment-related predictors of these treatment outcomes. Method: This study is registered in the International Prospective Register of Systematic Reviews (PROSPERO) under the number CRD42023418147. Nine electronic databases were searched to identify word retrieval treatment studies of poststroke BPWAs of at least 6 months postonset. Pre- and posttreatment single-word naming scores were extracted for each eligible participant and used to calculate effect sizes (within-case Cohen’s d) of the six treatment outcomes. Random-effects meta-analyses were conducted to assess weighted mean effect sizes of the treatment outcomes across studies. Multiple linear regression analyses were used to examine the effects of participant-related variables (pretreatment single-word naming and comprehension representing poststroke lexical processing abilities) and treatment-related variables (type, language, and duration). The methodological quality of eligible studies and the risk of bias in this meta-analysis were assessed. Results: A total of 17 published studies with 39 BPWAs were included in the meta-analysis. The methodological quality of the included studies ranged from fair (n = 4) to good (n = 13). Anomia treatment produced a medium effect size for TE (M = 8.36) and marginally small effect sizes for WLG-Related (M = 1.63), WLG-Unrelated (M = 0.68), and CLG-Tx (M = 1.56). Effect sizes were nonsignificant for CLG-Related and CLG-Unrelated. TE was significantly larger than the other five types of treatment outcomes. TE and WLG-Related effect sizes were larger for BPWAs with milder comprehension or naming impairments and for treatments of longer duration. WLG-Unrelated was larger when BPWAs received phonological treatment than semantic and mixed treatments. The overall risk of bias in the meta-analysis was low with a potential risk of bias present in the study identification process. Conclusions: Current anomia treatment practices for bilingual speakers are efficacious in improving trained items but produce marginally small within-language generalization and cross-language generalization to translations of the trained items. These results highlight the need to provide treatment in each language of BPWAs and/or investigate other approaches to promote cross-language generalization. Furthermore, anomia treatment outcomes are influenced by BPWAs’ poststroke single-word naming and comprehension abilities as well as treatment duration and the provision of phonological treatment [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to explore potential differences in suprathreshold auditory function among native and nonnative speakers of English as a function of age. Method: Retrospective analyses were performed on three large data sets containing suprathreshold auditory tests completed by 5,572 participants who were self-identified native and nonnative speakers of English between the ages of 18–65 years, including a binaural tone detection test, a digit identification test, and a sentence recognition test. Results: The analyses show a significant interaction between increasing age and participant group on tests involving speech-based stimuli (digit strings, sentences) but not on the binaural tone detection test. For both speech tests, differences in speech recognition emerged between groups during early adulthood, and increasing age had a more negative impact on word recognition for nonnative compared to native participants. Age-related declines in performance were 2.9 times faster for digit strings and 3.3 times faster for sentences for nonnative participants compared to native participants. Conclusions: This set of analyses extends the existing literature by examining interactions between aging and self-identified native English speaker status in several auditory domains in a cohort of adults spanning young adulthood through middle age. The finding that older nonnative English speakers in this age cohort may have greater-than-expected deficits on speech-in-noise perception may have clinical implications on how these individuals should be diagnosed and treated for hearing difficulties.

Purpose: We studied the role of gender in metacognition of voice emotion recognition ability (ERA), reflected by self-rated confidence (SRC). To this end, we guided our study in two approaches: first, by examining the role of gender in voice ERA and SRC independently and second, by looking for gender effects on the ERA association with SRC. Method: We asked 100 participants (50 men, 50 women) to interpret a set of vocal expressions portrayed by 30 actors (16 men, 14 women) as defined by their emotional meaning. Targets were 180 repetitive lexical sentences articulated in congruent emotional voices (anger, sadness, surprise, happiness, fear) and neutral expressions. Trial by trial, the participants were assigned retrospective SRC based on their emotional recognition performance. Results: A binomial generalized linear mixed model (GLMM) estimating ERA accuracy revealed a significant gender effect, with women encoders (speakers) yielding higher accuracy levels than men. There was no significant effect of the decoder’s (listener’s) gender. A second GLMM estimating SRC found a significant effect of encoder and decoder genders, with women outperforming men. Gamma correlations were significantly greater than zero for women and men decoders. Conclusions: In spite of varying interpretations of gender in each independent rating (ERA and SRC), our results suggest that both men and women decoders were accurate in their metacognition regarding voice emotion recognition. Further research is needed to study how individuals of both genders use metacognitive knowledge in their emotional recognition and whether and how such knowledge contributes to effective social communication.

Purpose: Children with developmental language disorder (DLD) tend to interpret noncanonical sentences like passives using event probability (EP) information regardless of structure (e.g., by interpreting “The dog was chased by the squirrel” as “The dog chased the squirrel”). Verbs are a major source of EP information in adults and children with typical development (TD), who know that “chase” implies an unequal relationship among participants. Individuals with DLD have poor verb knowledge and verb-based sentence processing. Yet, they also appear to rely more on EP information than their peers. This paradox raises two questions: (a) How do children with DLD use verb-based EP information alongside other information in online passive sentence interpretation? (b) How does verb vocabulary knowledge support EP information use? Method: We created novel EP biases by showing animations of agents with consistent action tendencies (e.g., clumsy vs. helpful actions). We then used eye tracking to examine how this EP information was used during online passive sentence processing. Participants were 4- to 5-year-old children with DLD (n = 20) and same-age peers with TD (n = 20). Results: In Experiment 1, children with DLD quickly integrated verb-based EP information with morphosyntax close to the verb but failed to do so with distant morphosyntax. In Experiment 2, the quality of children’s sentence-specific verb vocabulary knowledge was positively associated with the use of EP information in both groups. Conclusion: Depending on the morphosyntactic context, children with DLD and TD used EP information differently, but verb vocabulary knowledge aided its use. [ABSTRACT FROM AUTHOR]

Purpose: Clinicians are tasked with using culturally and linguistically appropriate tools to evaluate oral and written language development accurately. However, limited tools account for linguistic diversity in writing. This gap can lead to under-and overdiagnosis of students who speak nonmainstream dialects. This study addressed that gap by developing a writing task to identify nonmainstream dialect features in the writing of early elementary school students. We describe the development, feasibility, and results of pilot testing of the task. Method: One hundred fifty-one first and second graders participated in the study as part of a larger study of nonmainstream dialect use. Students completed standardized literacy and language assessments and the researcher-developed writing task. The writing task used a novel fill-in-the-blank format to identify morphological features that vary between Mainstream American English and nonmainstream varieties such as African American English. Results: Second-grade students performed better on the writing task than first graders, and writing performance was strongly related to standardized literacy scores. Literacy skills were the strongest predictor of Mainstream American English use in writing, but spoken dialect use also correlated with written dialect use. Conclusions: The writing task captured dialect use in early elementary school students' writing, and students' performance on standardized literacy measures predicted written dialect features. These results are a first step toward developing a standardized measure to help professionals appropriately diagnose written expression disorders within linguistically diverse students.

Purpose: The present study investigates the perception of vowel nasality in French-speaking children with cochlear implants (CIs; CI group) and children with typical hearing (TH; TH group) aged 4–12 years. By investigating the vocalic nasality feature in French, the study aims to document more broadly the effects of the acoustic limitations of CI in processing segments characterized by acoustic cues that require optimal spectral resolution. The impact of various factors related to children’s characteristics, such as chronological/auditory age, age of implantation, and exposure to cued speech, has been studied on performance, and the acoustic characteristics of the stimuli in perceptual tasks have also been investigated. Method: Identification and discrimination tasks involving French nasal and oral vowels were administered to two groups of children: 13 children with CIs (CI group) and 25 children with TH (TH group) divided into three age groups (4– 6 years, 7–9 years, and 10–12 years). French nasal vowels were paired with their oral phonological counterpart (phonological pairing) as well as to the closest oral vowel in terms of phonetic proximity (phonetic pairing). Post hoc acoustic analyses of the stimuli were linked to the performance in perception. Results: The results indicate an effect of the auditory status on the performance in the two tasks, with the CI group performing at a lower level than the TH group. However, the scores of the children in the CI group are well above chance level, exceeding 80%. The most common errors in identification were substitutions between nasal vowels and phonetically close oral vowels as well as confusions between the phoneme /u/ and other oral vowels. Phonetic pairs showed lower discrimination performance in the CI group with great variability in the results. Age effects were observed only in TH children for nasal vowel identification, whereas in children with CIs, a positive impact of cued speech practice and early implantation was found. Differential links between performance and acoustic characteristics were found within our groups, suggesting that in children with CIs, selective use of certain acoustic features, presumed to be better transmitted by the implant, leads to better perceptual performance. Conclusions: The study’s results reveal specific challenges in children with CIs when processing segments characterized by fine spectral resolution cues. However, the CI children in our study appear to effectively compensate for these difficulties by utilizing various acoustic cues assumed to be well transmitted by the implant, such as cues related to the temporal resolution of stimuli.

Objectives: We provide a novel application of psycholinguistic theories and methods to the field of auditory training to provide preliminary data regarding which minimal pair contrasts are more difficult for listeners with typical hearing to distinguish in real-time. Design: Using eye-tracking, participants heard a word and selected the corresponding image from a display of four: the target word, two unrelated words, and a word from one of four contrast categories (i.e., voiced-initial [e.g., peachbeach], voiced-final [e.g., back-bag], manner-initial [e.g., talk-sock], and mannerfinal [e.g., bat-bass]). Results: Fixations were monitored to measure how strongly words compete for recognition depending on the contrast type (voicing, manner) and location (word-initial or final). Manner contrasts competed more for recognition than did voicing contrasts, and contrasts that occurred in word-final position were harder to distinguish than word-initial position. Conclusion: These results are an important initial step toward creating an evidence-based hierarchy for auditory training for individuals who use cochlear implants. [ABSTRACT FROM AUTHOR]

Purpose: Social media sites provide autistic youth a familiar space to interact that is devoid of many of the challenges that accompany face-to-face interactions. As such, it is important to determine whether the linguistic profiles observed during online interactions are consistent with face-to-face interactions. This preliminary study took a step in this direction by examining gender differences observed in autistic adolescents in an online forum to determine whether they are consistent with the emerging body of research investigating linguistic gender differences in autistic adolescents. Method: We analyzed the entries of self-identified autistic adolescents in an online forum to determine whether autistic girls (n = 99) and boys (n = 94) differ in their use of linguistic features as a proportion of total words produced. Transcriptions were coded across discourse, lexical, and semantic features and compared to previous research investigating linguistic gender differences in autistic people. Exploratory comparisons were also made to linguistic gender differences in neurotypical people. Results: Of the linguistic features we examined, three out of four of the gendered usage patterns observed in the online forum language samples were consistent with previous research on face-to-face communication for autistic adolescents. Only one feature out of 12 occurred in the same gender distribution as previous research on neurotypical communication. Conclusions: Autistic girls and boys demonstrate largely consistent gender differences in their language use across in-person and online communication contexts. Interestingly, most of the significant gender differences previously reported in neurotypical communicators were not seen in this sample of autistic adolescents, suggesting that perhaps autistic individuals may linguistically express gender characteristics to a different extent or in a different manner than neurotypical individuals.

Purpose: Congenital amusia is a neurogenetic disorder of musical pitch processing. Its linguistic consequences have been examined separately for speech intonations and lexical tones. However, in a tonal language such as Chinese, the processing of intonations and lexical tones interacts with each other during online speech perception. Whether and how the musical pitch disorder might affect linguistic pitch processing during online speech perception remains unknown. Method: We investigated this question with intonation (question vs. statement) and lexical tone (rising Tone 2 vs. falling Tone 4) identification tasks using the same set of sentences, comparing behavioral and event-related potential measurements between Mandarin-speaking amusics and matched controls. We specifically focused on the amusics without behavioral lexical tone deficits (the majority, i.e., pure amusics). Results: Results showed that, despite relative to normal performance when tested in word lexical tone test, pure amusics demonstrated inferior recognition than controls during sentence tone and intonation identification. Compared to controls, pure amusics had larger N400 amplitudes in question stimuli during tone task and smaller P600 amplitudes in intonation task. Conclusion: These data indicate that musical pitch disorder affects both tone and intonation processing during sentence processing even for pure amusics, whose lexical tone processing was intact when tested with words.

Purpose: Narration within a story grammar framework requires speakers to organize characters and events logically. Despite abundant research characterizing narrative deficits following a traumatic brain injury (TBI), the evolution of narrative story grammar over the first 2 years post-TBI has rarely been explored. This study analyzed story grammar in complex narratives of adults with and without severe TBI to (a) examine between-group differences and (b) investigate longitudinal changes over the first 2 years post-TBI. Method: Story grammar analyses of Cinderella narratives from 57 participants with TBI and 57 participants with no brain injury yielded measures of productivity (total number of episodes, total number of story grammar elements), elaboration (total number of elaborated--complete episodes, mean number of episodic elements per episode), and completeness (total number of incomplete episodes). Mann--Whitney U tests compared measures across groups; generalized estimating equation (GEE) models identified predictors of change, including recovery time (3, 6, 9, 12, and 24 months post-TBI) and demographic/injury-related characteristics. Results: Between-group differences were statistically significant for all productivity and elaboration measures at 3, 6, and 9 months post-TBI; one productivity measure and one elaboration measure at 12 months; and none of the measures at 24 months. GEE models showed significant improvements in all productivity and elaboration measures over the first 24 months post-TBI, with educational attainment and duration of posttraumatic amnesia affecting recovery. Incomplete episodes only showed between-group differences at 12 months and did not capture recovery. Conclusion: Productivity and elaboration are key story grammar variables that (a) differentiate complex narration in individuals with and without severe TBI and (b) capture narrative improvements over the first 2 years post-TBI.

Purpose: This study aimed to explore how well persons with anomic aphasia communicate information during discourse regarding quantity, quality, and efficiency compared to neurotypical controls, to investigate the influence of discourse tasks on informativeness and efficiency and to examine impact factors like aphasia severity and cognitive ability. Method: Language samples of four discourse tasks from 31 persons with anomic aphasia and 31 neurotypical controls were collected from Mandarin AphasiaBank. Correct information unit (CIU) analysis measures including the total number of CIUs, percentage of CIUs, CIUs per minute, and words per minute were calculated. Group differences and the effects of discourse tasks on informativeness and efficiency were investigated. Correlations of CIU analysis measures with aphasia severity and cognitive ability were examined. Results: Persons with anomic aphasia showed lower efficiency in conveying information than controls. They underperformed controls on all CIU analysis measures when executing story narrative tasks. Discourse tasks influenced the informativeness and efficiency of both groups. Neurotypical controls delivered the greatest quantity of information most efficiently when narrating stories. Persons with anomic aphasia exhibited reduced quantity of information during procedural discourse and displayed superior information quality in sequential-picture descriptions. Discourse information may be impacted by aphasia severity and cognitive ability, with varying effects depending on the task. Conclusions: Persons with anomic aphasia are inefficient in communicating discourse messages and perform poorly on all measures in story narratives. When measuring discourse information, the effects of discourse tasks and factors like aphasia severity and cognitive ability should be considered. [ABSTRACT FROM AUTHOR]

Purpose: This study was designed to examine the hypothesis that discourse task types influence language performance in Mandarin Chinese--speaking people and to reveal the discourse task-specific linguistic properties of persons with anomic aphasia compared to neurotypical controls. Method: Language samples from persons with aphasia (n = 31) and age- and education-matched controls (n = 31) across four discourse tasks (sequential-picture description, single-picture description, story narrative, and procedural discourse) were collected from Mandarin AphasiaBank. Task-specific distributions of parts of speech were analyzed using mosaic plots. The main effects of tasks in each group and the between-group differences within each task for several typical linguistic variables were evaluated, including the mean length of utterance, tokens, moving-average type-token ratio, words per minute, propositional density, noun--verb ratio, noun percentage, and verb percentage. Results: The results revealed an impact of discourse tasks on most language variables in both groups. In the healthy controls, story narratives yielded the highest total words and lowest verb percentage. In the aphasia group, procedural discourse elicited the fewest total words and densest expressions, whereas their single-picture descriptions had the highest noun--verb ratio. For all tasks, the aphasia group performed worse than the control group in the mean length of utterance, tokens, moving-average type-token ratio, and words per minute. For noun--verb ratio, noun percentage, and verb percentage, only one task (i.e., single-picture description) showed significant between-group differences. Conclusion: The selection of discourse tasks should be addressed in assessments and interventions for Mandarin Chinese--speaking individuals with aphasia to obtain more accurate and feasible outcomes.

Purpose: Early impairments in spoken discourse abilities have been identified in Alzheimer's disease (AD). However, the impact of AD on spoken discourse and the associated neuroanatomical correlates have mainly been studied in populations with higher levels of education, although preliminary evidence seems to indicate that socioeconomic status (SES) and level of education have an impact on spoken discourse. The purpose of this study was to analyze microstructural variables in spoken discourse in people with AD with low-to-middle SES and low level of education and to study their association with gray matter (GM) density. Method: Nine women with AD and 10 matched (age, SES, and education) women without brain injury (WWBI) underwent a neuropsychological assessment, which included two spoken discourse tasks, and structural magnetic resonance imaging. Microstructural variables were extracted from the discourse samples using NILC-Metrix software. Brain density, measured by voxel-based morphometry, was compared between groups and then correlated with the differentiating microstructural variables. Results: The AD group produced a lower diversity of verbal time moods and fewer words and sentences than WWBI but a greater diversity of pronouns, prepositions, and lexical richness. At the neural level, the AD group presented a lower GM density bilaterally in the hippocampus, the inferior temporal gyrus, and the anterior cingulate gyrus. Number of words and sentences produced were associated with GM density in the left parahippocampal gyrus, whereas the diversity of verbal moods was associated with the basal ganglia and the anterior cingulate gyrus bilaterally. Conclusions: The present findings are mainly consistent with previous studies conducted in groups with higher levels of SES and education, but they suggest that atrophy in the left inferior temporal gyrus could be critical in AD in populations with lower levels of SES and education. This research provides evidence on the importance of pursuing further studies including people with various SES and education levels. What Is Already Known on This Subject: Spoken discourse has been shown to be affected in Alzheimer disease, but most studies have been conducted on individuals with middle-to-high SES and high educational levels. What This Study Adds: The study reports on microstructural measures of spoken discourse in groups of women in the early stage of AD and healthy women, with low-to-middle SES and lower levels of education. Clinical Implications of This Study: This study highlights the importance of taking into consideration the SES and education level in spoken discourse analysis and in investigating the neural correlates of AD.

Purpose: The purpose of this study was to examine the measurement structure of the linguistic features of speech-language pathologists' (SLPs) talk during business-as-usual therapy sessions in the public schools and to test the longitudinal stability of a theorized dimensional structure consisting of quantity, grammatical complexity, and lexical complexity. Method: Seventy-five SLPs' talk during therapy sessions with primary-grade students was automatically transcribed and coded for linguistic features from a corpus of 579 videotaped therapy session videos collected at the beginning, middle, and end of one school year with an approximately 12-week interval. We explored video characteristics and conducted descriptive statistics on eight linguistic indices of SLP talk to examine the variability in SLP talk between therapy sessions. Confirmatory factor analyses were used to explore the dimensional structure of SLP talk at each time point separately for the theorized three dimensions, and we conducted longitudinal measurement invariance analyses to test the stability of the three-factor structural model across the academic year. Results: There were considerable variabilities among SLPs in the characteristics of SLP talk during therapy sessions. The proposed three-factor structure of SLP talk consisting of quantity, grammatical complexity, and lexical complexity had good model fit at all three time points. The linguistic measurement properties representing the three factors were invariant over time. Conclusions: Results provided robust evidence of between-SLP variability in their child-directed talk, established a three-dimensional structure of the linguistic features in SLP talk, and identified that the linguistic features in SLP talk stably measured the same constructs across one school year, based on measurement invariance. The dimensions of SLP talk during therapy with students may represent important, malleable features of therapy that influence child language gains. [ABSTRACT FROM AUTHOR]

Purpose: This tutorial guides speech-language pathologists (SLPs) through the research base for expository intervention and evidence-based decision making for clinical implementation. Method: In the first half of the tutorial, the nature and development of expository discourse is described, and then attention is turned to the research base that informs SLP expository intervention. The many educational domains in which relevant research can be found and the diverse terminology used are explained. From reading comprehension and compositional writing, two areas with strong research evidence that are suitable to SLP use--text structure and learning strategies--are identified. The second half of the tutorial focuses on crafting SLP interventions from the educational evidence. An expository intervention designed specifically for SLPs from this research base, called Sketch and Speak, is presented. In this intervention, visual and written note-taking strategies are combined with oral formulation and practice strategies and taught through individualized oral interactions around informational texts. SLPs are guided on how to adapt this and other expository treatments to their own priorities and service delivery situations while maintaining quality features or "active ingredients" of researched treatments. Conclusions: There is considerable educational research on expository intervention. From this literature, SLPs can strategically adopt and adapt to implement evidence-based interventions to help students understand, speak, and write in this important discourse form.

Purpose: Naturalistic--developmental--behavioral interventions (NDBIs) are a widely accepted and validated approach for treating language-related symptoms in autism spectrum disorder, including deficits in vocabulary, social skills, and grammar. The purpose of this article is to define the elements naturalistic, developmental, and behavioral as applied to children with developmental language disorder (DLD) and to provide an example of how this type of intervention can be implemented to teach vocabulary and test cross-modal generalization between expressive and receptive modalities. Method: A vocabulary intervention using hybrid NDBI methods (storybook reading and conversational recast interaction) was provided to three participants with DLD using a single-case design. Results: The results indicated that all participants successfully learned receptive and expressive vocabulary targets with extensive cross-modal generalization. However, generalization was limited in some of the participants. Conclusions: This article provided definitions of key elements of NDBI (naturalistic, developmental, and behavioral) including a rationale for extending NDBI procedures to language intervention for children with DLD. In addition, a single-case design demonstrated that NDBI can be implemented in DLD and that broadly defined naturalistic--developmental applied behavior analysis techniques are applicable to language interventions for children with language disorders. Moreover, diverse naturalistic and developmental procedures meet the highest standards for evidence-based practice to treat DLD. [ABSTRACT FROM AUTHOR]

Purpose: We propose that implicit learning, including syntactic priming, has therapeutic promise to enhance the syntactic knowledge of children with developmental language disorder (DLD). Method: We review the chunk-based learning framework of syntactic learning, the developmental evidence in support of it, and the developmental literature on syntactic priming as an instance of chunk-based statistical learning. We use this framework to help understand the nature of the syntactic learning difficulties of children with DLD. We then briefly review the available explicit treatments for syntactic deficits and end by proposing an implicit training activity that integrates syntactic priming with the principles of statistical learning. Results: Statistically induced chunk-based learning is a powerful driver of syntactic learning, and syntactic priming is a form of this learning. Repeated priming episodes during everyday language interactions lead children to create abstract and global syntactic representations in long-term memory. We offer some thoughts on an implicit language intervention approach with syntactic priming at its center. Conclusions: Children's learning of syntactic structures is influenced by repeated syntactic priming experiences. Including a syntactic priming activity in our language intervention toolbox has the promise to enhance children's syntactic knowledge and sentence comprehension and production abilities.

Purpose: In this article, we present key concepts pointing to the importance of targeting complex sentences for school-age children and adolescents with developmental language disorders (DLD). Drawing on current treatment research, we argue that the sentence is a crucial but often neglected piece of the puzzle when it comes to understanding relationships between DLD and academic outcomes. We provide detailed suggestions for how clinicians can focus on complex sentence structures in natural academic contexts to bridge this gap. Method: Background information on sentence complexity is presented, along with a rationale for targeting complex sentences with school-age children and adolescents with DLD. Intervention methods from a variety of studies targeting multiclausal sentences are discussed in relation to current accounts of language learning and language processing models. We provide a robust catalog of suggested strategies for targeting sentence complexity in a manner that is aligned with research findings to date and integrated into real academic contexts. Conclusions: Complex sentence structures are a key challenge for students with DLD as they tackle discipline-specific language and academic tasks. Sentence complexity treatment programs employ one or more treatment methods including priming, modeling, recasting, contextualization, metalinguistic instruction, and sentence combining. While studies have consistently shown a measurable improvement in complex sentence production on proximal outcomes regardless of treatment approach, evidence of durable, functional changes for students with DLD remains sparse. We encourage new treatments that target comprehension and production of complex sentences in real-life academic contexts in clinical practice and research. [ABSTRACT FROM AUTHOR]

Purpose: For half a century, psycholinguists have been exploring the idea that developmental language disorders may have their roots in suprathreshold auditory dysfunctions, but results are inconclusive. Typical studies focus on relationships between temporal processing abilities and measures of various language skills at the time of testing, a proximal account. This study expanded that focus by testing three novel hypotheses: (a) Spectral processing impairments may be more responsible for language-learning deficits than temporal processing impairments. (b) Phonological sensitivity is likely the specific language skill most strongly affected by auditory (dys)functions. (c) Poor auditory functioning observed at young ages may wholly or partly recover, reducing the magnitude of relationship between those recovered functions and persistent language skills at older ages. Method: Sixty-six children (31 boys, 35 girls) 7-10 years of age participated: 36 with typical language and 30 with reading or speech disorder; from this sample two subsamples were designated: younger (7-8 years) and older (9-10 years) children. Four auditory measures were obtained of spectral modulation detection (0.5 and 2.0 cycles per octave) and temporal modulation detection (16 and 64 Hz). Four language measures were obtained, two lexicosyntactic and two phonological. Results: Younger children showed deficits in all auditory skills, but most strongly for spectral modulation detection at 0.5 cycles per octave; that measure was the only one for which older children showed deficits. Spectral modulation detection was the auditory function most strongly correlated with a language skill, and that language skill was phonological sensitivity. Conclusions: Early impairments in suprathreshold auditory functions, especially spectral processing, interfere with language acquisition at early stages, especially phonological sensitivity. Although auditory functions can recover to some extent, impairments in language skills persist, indicating that a distal account may more appropriately explain the relationship.

Purpose: This study focuses on 7- to 9-year-old children attending primary school in Swedish areas of low socioeconomic status, where most children's school language is their second language. The aim was to better understand what factors influence these children's narrative listening comprehension both in an ideal listening condition (in quiet) and for the primary school classroom, a typical listening condition (with multitalker babble noise). Method: A total of 86 typically developing 7- to 9-year-olds performed a narrative listening comprehension test (Lyssna, Förstå och Minnas [LFM]; English translation: Listen, Comprehend, and Remember) in two listening conditions: quiet and multitalker babble noise. They also performed the crosslinguistic nonword repetition test and a digit span backwards (DSB) test. A predictive statistical model including these factors, the children's degree of school language exposure, parental education level, and age was derived. Results: Listening condition had the strongest predictive value for LFM performance, followed by school language exposure and nonword repetition accuracy. Parental education level was also a significant predictor. There was a significant three-way interaction effect between listening condition, age, and DSB performance. Conclusions: Multitalker babble noise has a negative effect on children's narrative listening comprehension. The effect of multitalker babble noise could be explained by age differences in the ability to allocate working memory capacity during the narrative listening comprehension task, suggesting that younger children may be more vulnerable for missing information when listening in background noise than their older peers.

Purpose: To investigate the language environments experienced by pretermborn infants, this study compared the linguistic and interactive features of parent--infant conversations involving 2-year-old preterm- and term-born infants. The study also explored how mother--infant and father--infant conversations may be differentially affected by preterm/term birth status. Method: Twenty-two preterm-born (< 37 weeks' gestation) and 25 term-born (≥ 37 weeks' gestation) 2-year-old infants engaged in dyadic mother/father--infant free-play interactions that were transcribed to quantify the linguistic (parental volubility, speech rate, lexical diversity, and morphosyntactic complexity) and interactive (infant/parent responsiveness, turn-taking, and conversational balance) features of parent--infant conversations. Language, cognitive, socioemotional, and executive function skills were assessed via standardized tools. Results: Compared to the term group, the preterm group was characterized by lower maternal speech rate, parental lexical diversity, and parent--infant turntaking, as well as greater mother--infant conversational balance. The preterm group presented poorer language and executive function skills when compared to the term group. Conclusions: Both similarities and differences exist between the language environments of preterm and term groups. Similarities may be due to the partial developmental catch-up of preterm-born infants (cognitive and socioemotional skills) and parental scaffolding. Differences may partly reflect a parental adaptation to the language and executive function difficulties of preterm-born infants. These findings suggest that researchers/clinicians should appraise the language environment with respect to the unique developmental needs of preterm/term-born infants. Future research directions are provided to advance a more holistic characterization of the language environment and a deeper understanding of the developmental significance of preterm--term differences in such environments.

Purpose: The current study investigated English prosodic focus marking by autistic and typically developing (TD) Cantonese trilingual children, and examined the potential differences in this regard compared to native English-speaking children. Method: Forty-eight participants were recruited with 16 speakers for each of the three groups (Cantonese-speaking autistic [CASD], Cantonese-speaking TD [CTD], and English-speaking TD [ETD] children), and prompt questions were designed to elicit desired focus type (i.e., broad, narrow, and contrastive focus). Mean duration, mean fundamental frequency (F0), F0 range, mean intensity, and F0 curves were used as the acoustic correlates for linear mixed-effects model fitting and functional data analyses in relation to groups and focus conditions (i.e., broad, narrow, and contrastive pre-, on-, and post-focus). Results: The CTD group had post-focus compression (PFC) patterns via reducing mean duration, narrowing F0 range, and lowering mean F0, F0 curve, and mean intensity for words under both narrow and contrastive post-focus conditions, while the CASD group only had shortened mean duration and lowered F0 curves. However, neither the CTD group nor CASD group showed much of onfocus expansion (OFE) patterns. The ETD group marked OFE by increasing mean duration, mean F0, mean intensity, and higher F0 curve for words under on-focus conditions. Conclusions: The CTD group utilized more acoustic cues than the CASD group when it comes to PFC. The ETD group differed from the CASD and CTD groups in the use of OFE. Furthermore, both the CASD and CTD groups showed positive first language transfer in the use of duration and intensity and, potentially, successful acquisition in the use of F0 for prosodic focus marking. Meanwhile, the differences in the use of OFE between the Cantonese-speaking and English-speaking groups, not PFC, might indicate that Cantonese-speaking children acquire PFC prior to OFE.

Purpose: Our goal is to understand how the different types of plural marking are understood and processed by children with cochlear implants (CIs): (a) how does salience affect the processing of plural marking, (b) how is this processing affected by the incomplete signal provided by the CIs, and (c) is it linked to individual factors such as chronological age, vocabulary development, and phonological working memory? Method: Sixteen children with CIs and 30 age-matched children with normal hearing (NH) participated in an eye-tracking study. Their task was to choose the corresponding picture to an auditorily presented singular or plural noun. Accuracy, reaction time, and gaze fixation were measured and analyzed with mixed-effect models. Results: Group differences were found in accuracy but not in reaction time or gaze fixation. Plural processing is qualitatively similar in children with CIs and children with NH, with more difficulties in processing plurals involving stemvowel changes and less with those involving suffixes. Age effects indicate that processing abilities still evolve between 5 and 11 years, and processing is further linked to lexical development. Conclusions: Our results indicate that early implantation seems to be beneficial for the acquisition of plural as indicated by very small between-group differences in processing and comprehension. Processing is furthermore affected by the type of material (i.e., phonetic, phonological, or morphological) used to mark plural and less so by their segmental salience. Our study emphasizes the need to take into account the form of the linguistic material in future investigations at higher levels of processing. [ABSTRACT FROM AUTHOR]

Purpose: This study examined the differences in spoken Arabic (SpA) and standard Arabic (StA) in inflectional (gender, number, possessive pronouns, and tense) construction use in Arabic among preschoolers. Moreover, we tested the contribution of the inflectional constructions possessed in kindergarten to reading skills in the first grade and examined whether this morphological contribution differs between SpA and StA. Method: We assessed 261 Arabic-speaking kindergartners for 1 year until the end of first grade for inflectional knowledge in kindergarten and reading skills in first grade (reading accuracy and fluency, spelling, and reading comprehension). Results: The findings revealed that among inflections, prevalence of performance on gender constructions was the highest, followed by number and possessive pronouns, and lowest performance for tense constructions. Although the performance for SpA was higher than for StA in all constructions, similar patterns were observed except similarity between gender and number in StA. Moreover, the results indicate a significant contribution of almost all inflectional constructions (except possessive pronouns) possessed in kindergarten to all reading skills in the first grade. However, tense did not contribute to reading comprehension, and possessive pronouns did not contribute to any of the reading measures. Regarding diglossia, although the claims that linguistic components in StA are not represented in the mental lexicon, StA accounted for an additional significant 2%-3% of the explained variance in Step 2 (which checked the practical significance of statistically significant results) in all reading measures. Conclusions: This study highlights the impact of diglossia-specific morphological differences (prevalence of the use of the morphological construction in Arabic in SpA vs. StA) on reading and literacy measures, especially the contribution of morphological awareness in SpA, which may provide a stronger basis for StA reading skills. The implications of these results are discussed, especially regarding exposing children to the morphological representations of both the SpA and StA forms to promote reading and literacy in Arabic.

Purpose: According to most models of spoken word recognition, listeners probabilistically activate a set of lexical candidates, which is incrementally updated as the speech signal unfolds. Speech carries segmental (speech sound) as well as suprasegmental (prosodic) information. The role of the latter in spoken word recognition is less clear. We investigated how suprasegments (tone and voice quality) in three North Germanic language varieties affected lexical access by scrutinizing temporally fine-grained neurophysiological effects of lexical uncertainty and information gain. Method: Three event-related potential (ERP) studies were reanalyzed. In all varieties investigated, suprasegments are associated with specific word endings. Swedish has two lexical “word accents” realized as pitch falls with different timings across dialects. In Danish, the distinction is in voice quality. We combined pronunciation lexica and frequency lists to calculate estimates of lexical uncertainty about an unfolding word and information gain upon hearing a suprasegmental cue and the segment upon which it manifests. We used single-trial mixed-effects regression models run every 4 ms. Results: Only lexical uncertainty showed solid results: a frontal effect at 150-400 ms after suprasegmental cue onset and a later posterior effect after 200 ms. While a model including only segmental information mostly performed better, it was outperformed by the suprasegmental model at 200-330 ms at frontal sites. Conclusions: The study points to suprasegmental cues contributing to lexical access over and beyond segments after around 200 ms in the North Germanic varieties investigated. Furthermore, the findings indicate that a previously reported “pre-activation negativity” predominantly reflects forward-looking processing. [ABSTRACT FROM AUTHOR]

Purpose: Phonological awareness and alphabet knowledge are fundamental building blocks for literacy development. We identified preschoolers with persistent delays in these skills and evaluated the efficacy of a supplemental curriculum to remediate deficits in early literacy skills. Method: Using a cluster design, 21 classrooms were randomly assigned to early literacy versus language intervention conditions. Sixty children identified through fall semester assessments of phonological awareness and alphabet knowledge were enrolled in small-group instruction. Teachers completed eLearning modules, used a digital platform to enter data and facilitate data-based decision making, received practice-based coaching, and delivered 12 weekly units of an early literacy curriculum. Comparison teachers delivered similarly administered small-group language instruction. Results: Large effects were evident for letter sounds, phoneme segmentation, first sound, and first sound fluency measures (d = 0.92, 4.77, 1.15, and 1.50, respectively), and nonsignificant, small effects for letter naming and blending measures (d = 0.26 and 0.27). Discussion: This early literacy intervention package had practical benefits, with 90% of experimental group preschoolers exceeding the phonemic awareness benchmark for beginning kindergarten compared to 45% in the comparison group, for example. Providing preschool teachers with tools and support for implementing a tiered approach to early literacy intervention holds promise for producing impressive gains in skills required for children to succeed in later schooling.

Purpose: The purpose of the current study was to investigate the effect of vocabulary instruction embedded in the narrative intervention on the immediate and retained definitional knowledge of taught words for first graders at risk for language-related reading difficulties. Method: We employed a repeated acquisition design with innovative quality features and supplemental statistics with 11 treatment students and three control students. In the context of the school's multitiered system of supports, treatment students received 30-min small group interventions, 4 days a week for 12 weeks. Intervention involved story retelling and personal story generation lessons, both of which emphasized the learning and practicing of target vocabulary words in each story. Pre- and postprobes of the taught definitions were conducted every week. Results: According to visual analysis conventions of single-case research, there was a consistent pattern of improvement from pre- to postprobes for all treatment participants, but for none of the control participants. Retention was also consistently observed, when measured at Week 13. Supplemental statistics confirmed that large effects were associated with the intervention. Conclusion: Vocabulary instruction embedded in narrative intervention led to meaningful acquisition and retention of taught vocabulary for students at risk of language-based reading difficulty.

Purpose: The problems that people with aphasia encounter when reading passages are poorly understood. This study's purpose was in-depth examination of eye-gaze behaviors exhibited by five people with aphasia-based alexia. Method: Five adults with aphasia-based alexia and five neurotypical adults (NAs) read paragraphs while having their eye movements recorded. Acquired data included descriptive characterization of overall eye-gaze behaviors and determination of the (a) percent of fixated words, (b) average fixation duration, (c) average initial and total summed fixation durations of processing attempts on individual words, and (d) effects of word length and frequency on fixation durations. Careful examination of these data allowed examination of consistencies and discrepancies among people with aphasia and supported speculation about underlying deficits. Results: Case participants exhibited unique fixation behaviors in comparison to one another and to neurotypical adults. Case participants' total reading time, percent of fixated words, average fixation duration, and average initial and total summed fixation durations on passage words exceeded those of neurotypical adults. Four of five exhibited positive word length and negative word frequency correlations with fixation durations. Conclusions: People with aphasia display eye-gaze behaviors unique to them and differing from those of NAs when reading texts. Better understanding of the connection between specific eye-gaze behaviors and problems decoding words, linking them with lexical-semantic information, and constructing meaning from written content is necessary to further progress in developing effective assessment tools and treatments.

Purpose: Generalization has been defined and instantiated in a variety of ways over the last half-century, and this lack of consistency has created challenges for speech-language pathologists to plan for, implement, and measure generalization in aphasia treatment protocols. This tutorial provides an overview of generalization with a focus on how it relates to aphasia intervention, including a synthesis of existing principles of generalization and examples of how these can be embedded in approaches to aphasia treatment in clinical and research settings. Method: Three articles collectively listing 20 principles of generalization formed the foundation for this tutorial. The seminal work of Stokes and Baer (1977) focused attention on generalization in behavioral change following treatment. Two aphasia-specific resources identified principles of generalization in relation to aphasia treatment (Coppens & Patterson, 2018; Thompson, 1989). A selective literature review was conducted to identify evidence-based examples of each of these 20 principles from the extant literature. Results: Five principles of generalization were synthesized from the original list of 20. Each principle was supported by studies drawn from the aphasia treatment literature to exemplify its application. Conclusions: Generalization is an essential aspect of meaningful aphasia intervention. Successful generalization requires the same dedication to strategic planning and outcome measurement as the direct training aspect of intervention. Although not all people with aphasia are likely to benefit equally from each of the principles reviewed herein, our synthesis provides information to consider for maximizing generalization of aphasia treatment outcomes.

Purpose: We examined which measures of complexity are most informative when studying language produced in interaction. Specifically, using these measures, we explored whether native and nonnative speakers modified the higher level properties of their production beyond the acoustic–phonetic level based on the language background of their conversation partner. Method: Using a subset of production data from the Wildcat Corpus that used Diapix, an interactive picture matching task, to elicit production, we compared English language production at the dyad and individual level across three different pair types: eight native pairs (English–English), eight mixed pairs (four English–Chinese and four English–Korean), and eight nonnative pairs (four Chinese–Chinese and four Korean–Korean). Results: At both the dyad and individual levels, native speakers produced longer and more clausally dense speech. They also produced fewer silent pauses and fewer linguistic mazes relative to nonnative speakers. Speakers did not modify their production based on the language background of their interlocutor. Conclusions: The current study examines higher level properties of language production in true interaction. Our results suggest that speakers’ productions were determined by their own language background and were independent of that of their interlocutor. Furthermore, these demonstrated promise for capturing syntactic characteristics of language produced in true dialogue. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to examine whether older adults exhibit reduced abilities in coordinating lexical retrieval and syntactic formulation during sentence production and whether an individual’s working memory capacity predicts age-related changes in sentence production. Method: A total of 124 Korean-speaking individuals (79 young and 45 older adults) completed a lexical priming sentence production task. The participants described a target picture (a dog biting a monkey) after reading either an agent (dog) or a theme (monkey) prime word. The proportion of passive sentences was used as the dependent variable. Results: When the theme noun was primed, older adults produced fewer passive sentences than young adults. Working memory tasks significantly predicted individual differences in the sentence production of older adults. Conclusions: With aging, the ability to efficiently formulate syntactic structures in coordination with varying lexical information declines. Among older adults, age-related changes in these sentence production processes are associated with reduced working memory. Our constrained language production task is sensitive to detecting aging effects. [ABSTRACT FROM AUTHOR]

Purpose: This is the first study to investigate the combined effects of processing-based factors (i.e., clause length and clause order) and discourse-pragmatic factors (i.e., information structure) on children's and adults' production of adverbial when-clauses. Method: In a sentence repetition task, 16 three-year-old and 16 five-year-old children as well as 17 adults listened to and watched an animated story and then were asked to repeat what they had just heard and seen. Each story contained an adverbial when-clause and its main clause. The sentences were manipulated for their clause order, information structure, and clause length. Results: Adults tended to change main--when clause orders to when--main in their repetitions, and they showed a strong preference for the given--new order of information. In contrast, 3-year-olds tended to change when--main clause orders to main--when, and they showed a preference for the new--given order of information. In addition, 3-year-olds tended to produce short--long clause orders irrespective of what they had heard, whereas adults produced both short--long and long--short orders in line with the input. In general, 5-year-olds were more adultlike in their production compared to 3-year-olds. Conclusions: Young children were strongly affected by processing-based factors in their production of complex sentences. They tended to order main and when-clauses in a way that requires less planning and processing load. However, they have not yet attained an adultlike sensitivity to discourse-pragmatic factors.

Purpose: This study aims to illustrate the diverse modes and implications of pseudo-directive speech acts in Javanese, specifically emphasizing the Jogjakarta area. This field of pragmatics has garnered heightened attention in recent decades. However, it is worth noting that language researchers have not thoroughly examined these pragmatic studies and have not been extensively explored in linguistics. Method: The primary data source of the study consists of excerpts of verbal expressions within the familial context. The provenance of the locational data can be traced to a familial unit with a cultural legacy deeply embedded in Javanese customs. The data were collected using observation and participation methodologies, employing advanced techniques of recording and note taking. The data were categorized and characterized to identify the various data types and formats. The tabulated results of classification and typification are presented to triangulate theory through expert validation and justification of theories. The method of contextual analysis was utilized to conduct the data analysis that relies on the pragmatic context. Results: The study's findings indicate the following: The Javanese language encompasses various modes of pseudo-directive utterances, such as commanding, ordering, suggesting, insinuating, and recommending. In addition, the Javanese language encompasses pseudo-directive pragmatics such as warning, prohibiting, reminding, suggesting, and commanding. Conclusion: This research will significantly assist in formulating a pragmatic framework that considers cultural factors, as other linguistic phenomena in various regional languages remain unresolved.

Purpose: Lexical processing impairments such as delayed and reduced activation of lexical-semantic information have been linked to syntactic processing disruptions and sentence comprehension deficits in individuals with aphasia (IWAs). Lexical-level deficits can also preclude successful lexical encoding during sentence processing and amplify the processing costs of similarity-based interference during syntactic retrieval. We investigate whether two manipulations to engage attention and pre-activate semantic features of a target (to-be-retrieved) noun will (a) boost lexical activation during initial lexical encoding and (b) facilitate syntactic dependency linking through improved resolution of interference in IWAs and neurologically unimpaired age-matched controls (AMCs). Method: Eye-tracking-while-listening with a visual world paradigm was used to investigate whether semantic and attentional manipulations modulated initial lexical processing and downstream syntactic retrieval of the direct-object noun in object-relative sentences. Results: In the attention and semantic manipulations, the AMC group showed no changes in initial lexical access levels; however, gaze patterns revealed clear facilitations in dependency linking and interference resolution. In the IWA group, the attentional cue increased and maintained activation of N1 with modest facilitations in dependency linking. In the semantic condition, IWA results showed a greater degree of facilitation during dependency linking. Conclusions: The results suggest that attention and semantic activation are parameters that may be manipulated to strengthen encoding of lexical representations to facilitate retrieval (i.e., dependency linking) and mitigate similaritybased interference. In IWAs, these manipulations may help to reduce lexical processing deficits that can preclude successful encoding. [ABSTRACT FROM AUTHOR]

Purpose: Traditional approaches to studying bilingual language development through bilingual--monolingual comparisons are deeply flawed. They are also insufficient as the evidence base for informing advice to bilingual parents regarding the optimal bilingual exposure strategy and for supporting the formulation of bilingual intervention approaches. The purpose of this review article is to provide an overview of empirical studies that have queried the question of how different types of dual-language input shape learning and language outcomes in bilingual children. Method: We rely on tightly controlled experimental studies of word learning in Spanish--English bilingual children, where we contrast children's learning in dual-language conditions (defined as distributed exposure and code-switched input) to a single-language condition in a within-subjects design. Results: Word-learning studies querying the role of distributed exposure indicated that distribution of exposures across Spanish and English reduced children's performance in comparison to English-only exposure. However, this effect was rooted in the abrupt switch from Spanish to English rather than distributed exposure itself. In contrast, an experiment designed to test the role of code-switched context on children's word learning revealed that code-switched context where switches resembled naturalistic code-switching behaviors enhanced learning in Spanish--English bilingual children. Notably, across different studies, children with weaker language skills (developmental language disorder) were no more affected by dual-language input than children with typical language skills. Conclusions: Together, experimental studies of word learning indicate that bilingual children can effectively learn from dual-language input but that different ways of combining languages in the input to bilingual children can have distinct consequences for learning. Ultimately, word-learning experiments, beyond answering critical questions regarding bilingual learning, can serve as an effective bridge between laboratory-based work and intervention studies whose goal it is to discover the optimal way of combining languages in the input to bilingual children with communication impairments.

Purpose: Using the printed-word paradigm with eye tracking, this study conducted three experiments to examine (a) how multiple words in spoken overlapping ambiguity strings (OASs) are activated, (b) how word frequency influences the word segmentation of spoken OASs, and (c) whether the multiple words in spoken OASs are activated competitively or independently. Method: In this study, participants listened to a four-character spoken OAS (ABCD) and were presented with a visual display composed of a semantic associate of the "middle word" (BC; Experiments 1 and 2) or the "left word" (AB; Experiment 3) and two distractors. In Experiment 1, the word frequency of the middle words was manipulated to be higher than that of the neighbor words. In Experiment 2, the word frequency of the middle words was manipulated to be either higher or lower than that of the neighbor words. In Experiment 3, participants listened to either spoken OASs (ABCD) or spoken unambiguous strings (ABEF). Results: In Experiment 1, we observed a significant semantic competition effect; that is, more fixations fell on the semantic competitors than on distractors, suggesting that the semantic information of the middle words in the spoken OASs was activated. In Experiment 2, the semantic competition effect was only observed in the high-frequency condition and was absent in the lowfrequency condition. In Experiment 3, the results showed significant semantic competition effects for the left words under both conditions, and the observed effect was similar between the ambiguity condition and the control condition. Conclusions: These findings show that multiple words in spoken OASs are all activated and the activation level is modulated by word frequency. In addition, multiple words in the spoken OASs may be processed independently during spoken comprehension. [ABSTRACT FROM AUTHOR]

Purpose: The purpose of this study was to examine the growth of previously established clinical markers of developmental language disorder (DLD) in Spanish-speaking bilingual children with and without DLD. Method: Forty-three bilingual children with DLD and 57 typically developing children were tested 3 times over a 2-year period. Their average age at Time 1 was 5;10 (years;months). All children completed an elicitation task examining the production of articles, clitics, verbs, and the subjunctive mood in Spanish at each time point, in addition to other behavioral testing in Spanish and English. We used growth curve analysis to examine change patterns of the morphosyntactic structures over time. Results: At the onset of the study, children without DLD produced higher accuracy rates than children with DLD across all morphosyntactic structures. In addition, there was a positive effect of time on all structures. Furthermore, the interaction between time and DLD was statistically significant for clitic pronouns. Conclusion: In agreement with previous literature on language growth in monolingual children with DLD, bilingual children with DLD showed language growth that was parallel to that of bilingual children without DLD but with significantly lower levels of attainment.

Purpose: The purpose of this multiple probe design was (a) to investigate whether the use of the match-to-sample (MtS) procedure would result in independent identification of objects and (b) to examine whether the participants could generalize to matching objects and nonidentical pictures. Method: Using a nonconcurrent multiple baseline design, three minimally verbal preschoolers with autism spectrum disorder and receptive language impairment were taught to identify common objects using a MtS procedure and physical prompts. Participants were taught to match identical objects to identical pictures. Maintenance checks were completed following mastery of vocabulary for a total of 22 words. Generalization probes were conducted with the objects and nonidentical pictures. Intervention was completed by a speech-language pathologist during typical speech-language pathology sessions. Results: Results illustrated that all of the participants learned to match and generalize the pictures. All were able to independently identify the objects at 1-month follow-up. Conclusions: MtS and prompting appear to be effective procedures for teaching receptive vocabulary and can be easily implemented by education professionals. Learner profiles varied for the participants in this study and are an important aspect when teaching students with autism spectrum disorder and co-occurring receptive language impairment.

Purpose: This study examines the narrative language and reading outcomes of monolingual and bilingual students who received instruction with the Supporting Knowledge in Language and Literacy (SKILL) program, a narrative language intervention. Method: The main effects of the SKILL program were evaluated in a randomized controlled trial in which students (N = 355) who were at risk for English language and literacy difficulties were randomized to the SKILL intervention or a business-as-usual instruction. This article reports secondary analyses examining the efficacy of SKILL for bilingual (n = 148) and monolingual (n = 207) students who completed measures of oral and written narrative language and reading comprehension in English. Results: Moderation results showed that the effects of SKILL did not differ for monolinguals and bilinguals across most narrative language measures and did not vary for monolinguals or bilinguals based on their pre-intervention language performance. Conclusion: These findings that suggest a language-based approach to improving narrative production and comprehension yielded similar results for monolinguals and bilinguals and that neither monolinguals nor bilinguals in this study needed to meet a certain threshold of English language proficiency to benefit from the intervention.

Purpose: Language sampling is a critical component of language assessments. However, there are many ways to elicit language samples that likely impact the results. The purpose of this study was to examine how different discourse types and elicitation tasks affect various language sampling outcomes. Method: A diverse group of K-3 students (N = 1,037) contributed eight spoken language samples in four elicitation conditions: (a) expository generation, (b) expository retell, (c) narrative generation, and (d) narrative retell. Samples were audio-recorded, transcribed, and coded for number of total words, number of different words, mean length of utterance in words (MLUW), and number of clauses per communication unit (i.e., Subordination Index [SI]). Results: Narrative retell and expository generation conditions yielded the largest samples with the greatest lexical diversity when compared to narrative generation and expository retell. MLUW was higher in expository conditions, but mean SI was higher in narrative conditions. For both measures of syntax, narrative retell and expository generation yielded the highest mean scores. For each outcome, there were expected increases corresponding to grades; however, the differences faded between second and third grade. Conclusion: As a component of language assessments, clinicians' selection of language sampling procedures will impact the sample length, lexical diversity, utterance length, and syntactical complexity of the samples.

Purpose: This mixed-methods research sought to examine the experience of people with aphasia who used text-to-speech (TTS) support to read a novel for virtual book club participation. Method: Six people with chronic aphasia used a TTS system to review portions of a novel about which they conversed during eight virtual book club meetings occurring over 5 weeks. During one-on-one interactions prior to each meeting, participants answered comprehension questions and provided feedback about reading experiences. Then, during group meetings, they reviewed and discussed relevant book content and predicted upcoming content. During a structured individual interview, participants reflected on their supported reading and book club experience. Results: Participants reported a range of reading confidence prior to study participation, mostly influenced by decreased comprehension or reading speed. After book club participation, four participants expressed increased confidence. Some reported searching for key words and skipping difficult words as strategies additional to TTS support. All reviewed at least some book sections more than once either with or without TTS support. Highly motivated participants expressed low frustration and high reading ease and enjoyment. Perceived comprehension was roughly consistent with actual comprehension across participants. Most believed TTS support promoted faster reading than otherwise possible. Participants liked adjustable features affecting speech output rate, word or sentence highlighting, and font size. Psychosocial benefits included decreased isolation and increased friendship. Conclusions: The findings extend previous evidence about perceived and actual benefits associated with TTS support. People with aphasia express positive experiences when given TTS support during book club participation. [ABSTRACT FROM AUTHOR]

Purpose: This prospective, single-blinded, parallel, stratified, randomized clinical trial via telehealth aimed to investigate the impact of Startle Adjuvant Rehabilitation Therapy (START) on aphasia, apraxia of speech (AOS), and quality of life in individuals with chronic stroke. The study hypothesized that START would have a greater effect on AOS-related measures and more severe individuals. Method: Forty-two participants with poststroke aphasia, AOS, or both were randomly assigned to the START or control group. Both groups received 77-dB GET READY and GO cues during a word repetition task for three 1-hr sessions on consecutive days. The START group additionally received 105-dB white noise GO cues during one third of trials. The Western Aphasia Battery--Revised, Apraxia Battery for Adults, Stroke Impact Scale, and Communication Outcomes After Stroke scale were administered at Day 1, Day 5, and 1-month follow-up. Results: START improved performance on some subtests of the Western Aphasia Battery (Comprehension, Repetition, Reading) and measures of AOS (Diadochokinetic Rate, Increasing Word Length) in individuals with moderate/ severe aphasia, whereas moderate/severe controls saw no changes. Individuals with mild aphasia receiving START had improved Reading, whereas mild controls saw improved Comprehension. The START group had increased mood and perceived communication recovery by Day 5, whereas controls saw no changes in quality of life. Conclusions: This study is the first to evaluate the impact of training with startling acoustic stimuli on clinical measures of aphasia and AOS. Our findings suggest START can enhance both nontrained speech production and receptive speech tasks in moderate/severe aphasia, possibly by reducing poststroke cortical inhibition. Our findings should be considered carefully, as our limitations include small effect sizes, within-group variability, and low completion rates for quality-of-life assessments and follow-up visits. Future studies should explore a mechanism of action, conduct larger and longer Phase 2 clinical trials, and evaluate long-term retention. [ABSTRACT FROM AUTHOR]

Purpose: It is often assumed that phonological awareness only reflects children’s phonological skill. However, orthographic representations have been found to be automatically involved during phonological awareness tasks, which we refer to as automatic orthographic activation. Although previous longitudinal neural studies have addressed how phonological processing during phonological awareness tasks is bidirectionally related to reading skill in developing children, we do not know how automatic orthographic activation plays a role in reading skill. Method: To address this gap, we measured 40 children’s reading skill and brain activity during an auditory phonological task at two time points using functional magnetic resonance imaging. Children were 5.5 to 6.5 years old at the first time point and were followed up approximately 1.5 years later when they were 7 to 8 years old. Results: We found that earlier reading skill predicted children’s later functional connectivity during onset processing between the left superior temporal gyrus, a phonological region, and the left posterior ventral occipitotemporal cortex, an orthographic region representing letters. Conclusion: This finding, together with previous studies, suggests that learning to read influences phonological awareness not only by refining phonological representations but also via strengthening the automatic mapping between phonemes and letters during spoken language processing.
