The purpose of this study was to validate the Spanish version of the Family Involvement Questionnaire-Short Form (FIQ-SF) for use with Spanish-speaking families of children enrolled in early childhood education programs. This study examined the factor structure of the FIQ-SF and established criterion validity for the resulting FIQ-SF dimension scores. Results from exploratory and confirmatory factor analyses replicated the three dimensions of the English FIQ: Home Engagement, School Engagement, and home-school Conferencing. Mean differences across family demographics were examined. Criterion-related validity for the three FIQ-SF dimensions was established by examining correlations with scores on measures of parent-reported satisfaction with educational experiences, program records of family engagement, direct assessments of child language skills and teacher-reported approaches to learning. Future directions and practice implications for the use of the Spanish FIQ-SF to inform program policy and interventions are discussed.

Background: The language that children are exposed to in their early years is enhanced by children's picture books. It is important to better characterise this input, and recent research has begun to explore corpora of narrative picture books. However, previous research has been restricted by methodological limitations that make it difficult to develop large datasets. Further, information texts become increasingly important as children progress through school, but little is known about the language of their earliest form, namely, informational picture books. The current study investigates how informational and narrative picture book exposure might change the language environment of children in a way that supports reading development. Methods: The study applies data science methods to build a larger language model than previously possible and investigates the lexical profile of over 2000 narrative and information picture books. Picture book vocabulary is innovatively derived from digital sources of books read-aloud online, which pushes the field forward by providing researchers access to larger pools of data than previously possible. Detailed comparisons of informational and narrative picture books are reported regarding their lexical diversity, density, morphology, academic vocabulary and semantic clusters. Models are developed to estimate the additional word-type exposure a child may encounter in their language environment from narrative and informational picture books. Results: The study demonstrates that information and narrative picture books expose children to substantially different semantic environments. It is demonstrated that information picture books provide extensive exposure to academic vocabulary, providing important input aligned with later reading needs. Further, computational models indicate that book reading once every day or second day over a year might boost unique-word exposure by approximately 10% for some language environments. Conclusions: Combining informational and narrative picture books enhance the language environment of children more than narratives alone, providing more lexical diversity, density and complex morphology.

The relationship between emotion and language in children is an emerging field of research. To carry out this type of study, researchers need to precisely manipulate the emotional parameters of the words in their experimental material. However, the number of affective norms for words in this population is still limited. To fill this gap, the present report presents a set of 7 norms that measure the emotional parameters (valence, arousal) of words rated by children in French, English, German, Spanish, and Chinese. The high correlations between the valence values and the moderate correlations between arousal values of these norms allow us to determine a cross-language homogeneity of emotional representations in children. Thus, this report introduces a significant metanorm with 508 words characterized by valence and by arousal. This tool is a worthwhile resource for researchers interested in the links between emotion and language, as well as for those interested in cross-language comparisons.

Recent studies have accumulated to suggest that children, akin to adults, exhibit a processing advantage for formulaic language (e.g. "save energy") over novel language (e.g. "sell energy"), as well as sensitivity to phrase frequencies. The majority of these studies are based on formulaic sequences in their canonical form. In natural language use, however, many formulaic sequences, collocations in particular, can be modified with words intervening in between the individual constituents (e.g. "save energy [right arrow] save all forms of energy"). For some collocations, their nonadjacent forms are equally, and even more frequently used than their adjacent form. Despite this, it remains almost unknown whether the processing advantage and sensitivity to phrase frequencies persist in nonadjacent collocations in children. Based on reading times in a self-paced reading experiment, the current study found that two age groups -- third and sixth graders -- exhibited a processing advantage for Chinese collocations and sensitivity to phrase frequencies, with two and even four Chinese characters inserted in the middle. The persistence of processing advantage and sensitivity was affected by insertion length as well as age. These results are in line with a usage-based theoretical approach to language learning, processing and use.

Toddlers with smaller vocabulary than expected for their age are considered late talkers (LT). This study explored the effects of characteristics of words on vocabulary acquisition of 12- to 24-month-old LT children compared with an age matched (AM) and a vocabulary matched (VM) group of typically developing peers. Using the Hebrew-MacArthur-Bates-Communicative Development Inventory questionnaire, words were rated by adults for babiness, concreteness and iconicity and scored for phonological complexity. The effects of the characteristics of the words on their acquisition were examined. Results showed that the vocabulary of the toddlers from all three groups consisted of words that are more relevant to a child's world and experience (babiness), more concrete, more phonologically simple, and more iconic. When LT children were compared to AM children, the characteristics of their vocabulary were different in terms of structure (e.g., iconicity) and meaning (e.g., concreteness), but similar in phonological complexity and babiness. When they were compared to VM peers, the vocabulary characteristics of LT children were similar, though they used words that were less related to babies' world. The parallel patterns found for LT and VM children versus AM children suggest that LT children's vocabularies differ from those of their age-matched peers due to their smaller size and not due to structural differences. The implications for theory and clinic are discussed.

Causation is a core feature of human cognition and language. How children learn about intricate causal meanings is yet unresolved. Here, we focus on how children learn verbs that express causation. Such verbs, known as lexical causatives (e.g., break and raise), lack explicit morphosyntactic markers indicating causation, thus requiring that the child generalizes the causal meaning from the context. The language addressed to children presumably plays a crucial role in this learning process. Hence, we tested whether adults adapt their use of lexical causatives to children when talking to them in day-to-day interactions. We analyzed naturalistic longitudinal data from 12 children in the Manchester corpus (spanning from 20 to 36 months of age). To detect semantic generalization, we employed a network approach with semantics learned from cross-situational contexts. Our results show an increasing trend in the expansion of causative semantics, observable in both child speech and child-directed speech. Adults consistently maintain somewhat more intricate causative semantic networks compared to children. However, both groups display evolving patterns. Around 28-30 months of age, children undergo a reduction in the degree of causative generalization, followed by a slightly time-lagged adjustment by adults in their speech directed to children. These findings substantiate adults' adaptation in child-directed speech, extending to semantics. They highlight child-directed speech as a highly adaptive and subconscious teaching tool that facilitates the dynamic processes of language acquisition.

Previous research shows that infants of parents who are more likely to engage in socially contingent interactions with them tend to have larger vocabularies. An open question is "how" social contingency facilitates vocabulary growth. One possibility is that parents who speak in response to their infants more often produce larger "amount of language input," which accelerates vocabulary growth. Another possibility is that the "simplicity of contingent language input" is especially suitable to support early word learning. A third possibility is that more evidence of the communicative nature of language, achieved through "frequent contingent responses," helps infants build a link between their own words or vocalizations and others' behaviors. This link may lead to a better understanding of the communicative nature of language and further language advances, including vocabulary growth. To distinguish between these hypotheses, we analyzed the relations between parent-infant interactions when infants were 9 months and their vocabulary size at 12 months, using a naturalistic corpus. Our findings show that the frequency of parents' verbal contingent responses predicts receptive vocabulary size at 12 months and this predictive relation is unlikely to be due to the amount of language input or the simplicity of language within socially contingent interactions.

The dynamic nature of multilingual families and their language policies has been touched upon by numerous studies. Adding to the field, the present study assesses the stability of family language policy in a standardised and quantitative manner. To this end, a linguistically heterogenous sample consisting of 488 multilingual families raising young children in Belgium's Flemish Community was surveyed twice, eighteen months apart. Based on the collected longitudinal survey data, the present study offers statistically verifiable evidence for the (partially) dynamic character of family language policy. Firstly, parental beliefs in a multilingual advantage were strengthened and a change was found in language-specific beliefs regarding children's language acquisition. Secondly, the families' practices demonstrate a shift towards the Dutch institutional language, particularly in parental language use when communicating with each other and with their child, and in the child's overall exposure. The observed shift in practices and beliefs underscores not only parents' continuous assessment of their children's linguistic needs and development, but also the societal environment influencing this assessment and adjustment. However, while significant changes in language beliefs and practices were uncovered, the more conscious and explicit component of language management proved stable across time, corroborating the independent character of the three family language policy components.

Both participation and argumentation (OECD, 2022) are important keywords in educational contexts. While participation is seen as a crucial prerequisite for education and collaborative learning in general, argumentation as a discursive practice serves to convey and negotiate--also school-specific--knowledge. This paper explores repetition in argumentative events as a technique of establishing--or even hindering--participation in terms of alignment and affiliation. It can serve as a strategy for participation by signalling responsiveness and thematic coherence--and thus inclusion. At the same time, however, studies show that repetition can also signal contradiction and rejection--and thus exclusion. So far, we know little about how exactly these functional differences are produced--especially in younger children. Therefore, the paper explores how children use repetition as a resource for negotiating participation in argumentative events. Using authentic data in the form of observations and transcriptions of audio and video recordings from child-child-interactions of 15 Hebrew- and 31 German-speaking children aged 3-6 years, we identify oral argumentative events and investigate different forms of repetitions and their respective relevance for enabling participation. Our results show that, on the one hand, minimal and partial repetitions are used by the children in an inclusive way, creating closeness between the participants. On the other hand, children use complete repetitions more as an excluding technique, displaying misalignment and disaffiliation, in order to challenge and mock each other. The findings suggest that this line of research has significant potential to provide new insights into the formation of social relationships between peers, into the prevention or establishment of participation, which itself is a prerequisite for joint learning, as well as insights into the acquisition of argumentative competence.

Infants' preference for vowelharmony (VH, a phonotactic constraint that requires vowels in a word to be featurally similar) is thought to be language-specific: Monolingual infants learning VH languages show a listening preference for VH patterns by 6 months of age, while those learning non-VH languages do not (Gonzalez-Gomez et al., 2019; Van Kampen et al., 2008). We investigated sensitivity to advanced tongue root (ATR) harmony in Akan (Kwa, Niger-Congo) in 40 six-month-old multilingual infants (21 girls) in Ghana, West Africa (an understudied population), all learning Akan, Ghanaian English, and most of them several other understudied African languages (e.g., Ga, Ewe). We hypothesized that infants learning both ATR harmony and nonharmony languages would demonstrate sensitivity to ATR harmony. Using the central fixation procedure, infants were presented with disyllabic nonwords that were either harmonic (e.g., puti) or nonharmonic (e.g., pet[open-mid back rounded vowel]) based on their ATR features. Infants demonstrated sensitivity to ATR harmony with a familiarity preference, listening longer to harmonic syllable sequences than nonharmonic ones. The relative amount of exposure to (an) ATR harmony language(s) did not modulate the preference. These results shed light on our understanding of early multilingualism: they suggest that early sensitivity to VH in multilinguals may be similar to monolingual infants learning other types of VH, irrespective of simultaneous experience with non-VH languages. We conclude with reflections on studying infant language acquisition in multilingual Africa.

New motor skills can shape how infants communicate with their caregivers. For example, learning to walk allows infants to move faster and farther than they previously could, in turn allowing them to approach their caregivers more frequently to gesture or vocalize. Does the link between walking and communication differ for infants later diagnosed with autism spectrum disorder (ASD), whose communicative and motor development differs from their neurotypically developing peers? We prospectively followed two groups of infants longitudinally during the transition from crawling to walking: (1) N = 25 infants with no family history of ASD; and (2) N = 91 infants with an older sibling with ASD. Fifteen infants were later diagnosed with ASD, and 26 infants showed a language delay (but did not receive an ASD diagnosis). After learning to walk, infants without ASD or language delay showed considerable changes in their communication: They gestured more frequently, and increasingly coordinated their gestures and vocalizations with locomotion (e.g., by approaching a caregiver and showing a toy). Infants with language delay showed similar but attenuated growth in their communication. However, infants later diagnosed with ASD did not display enhanced communication after they began to walk.

This article explores the applicability of mean length of utterance (MLU) as a language assessment measure for Georgian child language, as to-date, Georgian, a morphologically rich language with numerous inflectional categories, experiences an extensive lack of instruments for early language assessment. To this end, a set of guidelines for calculating Georgian MLU was developed based on the analysis of a longitudinal corpus of two Georgian-speaking children aged 12-35 months. This was supported by the findings of previous studies on Georgian acquisition. Furthermore, the guidelines were used to compare MLU in morphemes (MLU-m) with MLU in words (MLU-w) and MLU in syllables (MLU-s) to determine the most suitable method for assessing morphological development in Georgian. These results indicate that MLU-m closely aligns with the description of language development in Georgian children. MLU-s is useful for demonstrating early linguistic development, while MLU-w correlates with age but does not capture changes within words over time. Further testing on a larger corpus is needed to refine the guidelines for more accurate assessment of Georgian-speaking children.

Oral language is the primary means through which a child controls, describes, organises, and evaluates their life experiences and their ability to use oral language which effectively impacts their future literacy development. Currently, the world is awash with dynamic change and constant disruption. These include natural disasters such as the ongoing Australian floods and bush fires, droughts, the global COVID-19 pandemic, the pervasive use of digital technologies, continuing global unrest, and impacts on economic and social adversity. Many of these disruptions are having a negative impact on the development of children's oral language and ongoing communication capacities. This is interesting given the prioritisation in many western nations, including Australia, of learning to read and write over learning to talk and communicate. This paper serves as an example of what makes good classroom literacy research. It outlines the elements of robust research including a research proposal structure. In this instance, our research investigates educator perceptions of children's developing oral language and communication skills and practices in birth to 8-year-old education contexts within the current backdrop of extreme disruption. The paper includes a literature review, our proposed research methodology which includes interviews from participants in birth to 8-year-old education settings, in both national and global contexts sourced via snowball sampling. The data analysis uses Fairclough's Critical Discourse Analysis (CDA) of the contextualised interview responses from educators within a socio-cultural global malaise of disruption and power. We outline future plans and funding sources, including publications and potential school resources in the spirit of collegial cooperation to support excellence in literacy classroom research.

Purpose: This study examines the accuracy of Interaction Detection in Early Childhood Settings (IDEAS), a program that automatically transcribes audio files and estimates linguistic units relevant to speech-language therapy, including part-of-speech units that represent features of language complexity, such as adjectives and coordinating conjunctions. Method: Forty-five video-recorded speech-language therapy sessions involving 27 speech-language pathologists (SLPs) and 56 children were used. The F measure determines the accuracy of IDEAS diarization (i.e., speech segmentation and speaker classification). Two additional evaluation metrics, namely, median absolute relative error and correlation, indicate the accuracy of IDEAS for the estimation of linguistic units as compared with two conditions, namely, Oracle (manual diarization) and Voice Type Classifier (existing diarizer with acceptable accuracy). Results: The high F measure for SLP talk data suggests high accuracy of IDEAS diarization for SLP talk but less so for child talk. These differences are reflected in the accuracy of IDEAS linguistic unit estimates. IDEAS median absolute relative error and correlation values for nine of the 10 SLP linguistic unit estimates meet the accuracy criteria, but none of the child linguistic unit estimates meet these criteria. The type of linguistic units also affects IDEAS accuracy. Conclusions: IDEAS was tailored to educational settings to automatically convert audio recordings into text and to provide linguistic unit estimates in speech-language therapy sessions and classroom settings. Although not perfect, IDEAS is reliable in automatically capturing and returning linguistic units, especially in SLP talk, that are relevant in research and practice. The tool offers a way to automatically measure SLP talk in clinical settings, which will support research seeking to understand how SLP talk influences children's language growth.

What is vision's role in driving early word production? To answer this, we assessed parent-report vocabulary questionnaires administered to congenitally blind children (N = 40, Mean age = 24 months [R: 7-57 months]) and compared the size and contents of their productive vocabulary to those of a large normative sample of sighted children (N = 6574). We found that on average, blind children showed a roughly half-year vocabulary delay relative to sighted children, amid considerable variability. However, the content of blind and sighted children's vocabulary was statistically indistinguishable in word length, part of speech, semantic category, concreteness, interactiveness, and perceptual modality. At a finer-grained level, we also found that words' perceptual properties intersect with children's perceptual abilities. Our findings suggest that while an absence of visual input may initially make vocabulary development more difficult, the content of the early productive vocabulary is largely resilient to differences in perceptual access.

To address the variability of naturalistic developmental behavioral intervention outcomes, the current study sought to isolate the effects of the instructional strategies of caregiver-mediated naturalistic developmental behavioral interventions. In this comparative efficacy trial, mothers of 111 autistic children (18-48 months) were randomized to learn one of two sets of naturalistic developmental behavioral intervention language facilitation strategies (responsive or directive). We aimed to characterize the effect of strategy type on language outcomes and explore the extent to which joint engagement outcomes mediated language outcomes. Children in the directive condition had significantly greater scores across multiple language assessments. At follow-up, the effect of strategy type on the frequency of spontaneous directed communication acts was fully mediated by coordinated joint engagement (indirect effect = -2.070, 95% CI = [-4.394, -0.06], p < 0.05). Thus, children may benefit from caregiver prompts to facilitate long-term language outcomes. The current study is an initial step in the identification of the mechanisms of caregiver-mediated NDBIs.

Children achieve better long-term language outcomes than adults. However, it remains unclear whether children actually learn language "more quickly" than adults during real-time exposure to input--indicative of true superior language learning abilities--or whether this advantage stems from other factors. To examine this issue, we compared the rate at which children (8-10 years) and adults extracted a novel, hidden linguistic rule, in which novel articles probabilistically predicted the animacy of associated nouns (e.g., "gi lion"). Participants categorized these two-word phrases according to a second, explicitly instructed rule over two sessions, separated by an overnight delay. Both children and adults successfully learned the hidden animacy rule through mere exposure to the phrases, showing slower response times and decreased accuracy to occasional phrases that violated the rule. Critically, sensitivity to the hidden rule emerged much more quickly in children than adults; children showed a processing cost for violation trials from very early on in learning, whereas adults did not show reliable sensitivity to the rule until the second session. Children also showed superior generalization of the hidden animacy rule when asked to classify nonword trials (e.g., "gi badupi") according to the hidden animacy rule. Children and adults showed similar retention of the hidden rule over the delay period. These results provide insight into the nature of the critical period for language, suggesting that children have a true advantage over adults in the rate of implicit language learning. Relative to adults, children more rapidly extract hidden linguistic structures during real-time language exposure.

Subject relative clauses (RCs) have been shown to be acquired earlier, comprehended more accurately, and produced more easily than object RCs by children. While this subject preference is often claimed to be a universal tendency, it has largely been investigated piecemeal and with low-powered experiments. To address these issues, this meta-analysis follows an established and rigorous scientific method to test the generalizability of the subject preference in RC acquisition by evaluating the collective evidence. While the results show a significant crosslinguistic subject preference, there is a large amount of heterogeneity in the data. The manifestation of this subject preference may not be uniform across languages, depending on typological properties such as language headedness, RC headedness, and main clause similarity. The true impact of these features, however, requires research on more typologically diverse languages.

Inspired by research in language play and linguistic ethnography, this article examines children's language play in early childhood education and care (ECEC) as a locally situated generic practice created through children's semiotic repertoires. The article is based on video-recorded linguistic ethnographic fieldwork in a Danish day care centre. By analysing two play sequences with 3-4 year old children, we examine how the children align to each other in an improvised way while co-creating social worlds. The multimodal micro-ethnographic analysis reveals how an assemblage of chunks of language, musicality, movements, affect and materiality is constitutive of children's language play, and how language play appears as an integral part of children's local language practices. The children's use of a broad range of semiotic repertoires in language play represents a unique practice that might enhance our theoretical and empirical understanding of child language. We argue that empirical insight into children's language play has the potential for developing paths to language and literacy that challenge the often highly prioritised 'precursors to literacy' strategy as the central aim for language learning in ECEC.

Despite policies favoring delivery of interventions for children with communication disorders in the classroom, most school-based interventions are delivered outside the classroom. Both teachers and speech-language pathologists (SLPs) have been found to have positive attitudes toward classroom-delivered intervention and the collaboration skills required to implement it. The purpose of this study was to explore preservice teacher and SLP attitudes toward inclusive service delivery and perceptions of their collaboration skills. The study used convergent mixed-methods, two-group design with participants completing an assignment requiring interprofessional collaboration. Twenty-nine preservice teachers and SLPs consented to the preassignment survey, and 37 consented to the postassignment survey. Compared to preservice teachers, preservice SLPs more strongly agreed that interventions are best delivered in the classroom. After the collaborative assignment, participants more strongly agreed that SLPs should implement classroom-based interventions. The preservice SLPs more strongly agreed that they had skills to identify children's language needs in the classroom. Barriers to collaboration included differences in goals, role understanding, and level of preparation across the professions. The findings suggest that to foster more inclusive delivery, professional preparation programs require more focus on building skills in respectfully managing differences in what each professional brings to classroom-based language interventions.

A majority of children's language learning experiences occur in inclusive early child care and education settings. Few evidence-based professional development (PD) programs exist to empower early childhood education providers to use language instruction practices with children in inclusive classrooms. There is little research on providers' implementation of naturalistic developmental behavioral intervention (NDBI) strategies to improve children's language outcomes in whole-group inclusive instruction. We conducted a pilot cluster randomized controlled trial to test the hypothesis that providers in the Early Achievements for Child Care Providers (EA-CP) PD program would show greater gains in NDBI implementation fidelity during shared book reading relative to business-as-usual (BAU) providers. This hypothesis was confirmed. Compared to BAU providers, EA-CP providers exhibited significantly greater fidelity gains from pre-training to mid-training, post-training, and 12-week maintenance assessments. A secondary hypothesis was that toddlers with and without developmental delays in the EA-CP condition would exhibit greater vocabulary and communication gains than toddlers in the BAU condition. Analyses of children with and without delays showed significantly greater expressive vocabulary and story-related engagement and communication in the EA-CP group. For children with delays, positive effects favoring the EA-CP group but not statistically significant were found. Implications for research, practice, and policy are discussed.

Background: Drawing on the family stress model (Conger and Donnellan in Ann Rev Psychol 58:175-199, 2007. https://doi.org/10.1146/annurev.psych.58.110405.085551), parenting programs typically support caregivers' nurturing and cognitively stimulating practices to mitigate the effects of poverty on child development, with small-to-moderate intervention effect sizes. Objective: This study evaluated a nonrandomized parenting program in Turkiye for low-income pregnant women and mothers of infants. The program utilized home visiting (HV) implemented by local municipalities for the first time. It was hypothesized that program mothers would engage in cognitively-stimulating practices more often at child age 9 months, and thereby expand their child's vocabulary at 18 months of age. Subgroup analyses based on maternal depression were also conducted. Methods: Using a quasi-experimental design, 526 mothers were allocated to one of two groups: HV intervention (n = 282, 77% pregnant) vs. control (n = 244, 69% pregnant). Mothers completed questionnaires on family and environmental risk at enrollment (T1), on depression and stimulating parenting at infant age 9 months (T2), and child vocabulary at 18 months (T3). Results: HV mothers reported stimulating parenting more frequently than controls at T2. Enrollment in HV predicted larger child vocabulary at T3 through stimulating parenting at T2. Subgroup differences were not detected. Conclusions: Results suggested that HV is a promising strategy to offer parent coaching to economically disadvantaged Turkish families. Though the present study made statistical adjustments to minimize group nonequivalence in baseline, selection bias might pose a threat to internal validity. A randomized controlled trial is warranted to examine its impact more rigorously prior to wider scale implementation.

While it is established that parental "wh"-questions, as a high-quality language input, are associated with child language outcome, less is known about the role of children's "wh"-questions in their language development. This study examines whether children's "wh"-questions during a dinnertime conversation are associated with their receptive and expressive language skills. The sample consists of a unique group of bilingual children: 32 Chinese preschoolers (aged 3-5 years) in Norway. At the onset of the study, parents self-recorded a dinnertime conversation with the target child and other family members present. Over the following year, we assessed children's receptive vocabulary, expressive vocabulary, and narrative skills in Chinese three times. Individual growth modeling revealed that concurrently, the density of children's "wh"-questions was associated with children's expressive vocabulary and narrative skills, but the association faded when controlling for family demographics. Significantly, even when accounting for all control variables, children's "wh"-questions predicted their receptive vocabulary growth across one year. These findings underline children's active role in shaping their language learning and development. This study also contributes to our understanding of bilingual children's home language development. Implications and directions for future research are discussed.

Purpose: Previously, Lancaster and Camarata (2019) showed that the continuum/spectrum model of the developmental language disorder (DLD) best explained the high heterogeneity of symptoms in children with DLD. We hypothesize that the continuum/spectrum approach can include not only children with DLD but also typically developing (TD) children with different timelines and patterns of language acquisition. This model can explain individual language profiles and deficits in children. Method: We assessed language abilities in a group of Russian-speaking children with DLD aged 4-7 years (n = 53) and their age- and gender-matched peers without speech and language diagnoses (n = 53, TD). We evaluated the children's performance at four language levels in production and comprehension domains, using 11 subtests of the standardized language assessment for Russian: Russian Child Language Assessment Battery (RuCLAB). Using the k-means cluster method and RuCLAB scores, we obtained two clusters of children and analyzed their language performance in individual subtests. Results: The analysis revealed that the two clusters of children both included DLD and TD participants: Group 1, with higher test scores (TD = 45, DLD = 24 children), and Group 2, with lower scores (TD = 8, DLD = 29). Children from Group 1 mostly had lower scores at one of the language levels, whereas those from Group 2 struggled at several language levels. Furthermore, children with DLD from both groups tended to be more sensitive to linguistic features such as word length, noun case, and sentence reversibility compared to TD children. Conclusions: The presence of two mixed groups shows that children with diagnosed DLD could perform on par with TD children, whereas some younger TD children could perform similarly to children with DLD. Our findings support the continuum/spectrum model: Linguistic skills in preschool children are a continuum, varying from high to poor skills at all language levels in comprehension and production. To describe a child's language profile, the tasks assessing all language levels should be used.

Objectives: The study aimed to investigate the predictive potential of language environment and vocal development status measures obtained through integrated analysis of Language ENvironment Analysis (LENA) recordings during the prelinguistic stage for subsequent speech and language development in Korean-acquiring children. Specifically, this study explored whether measures from both LENA-automated analysis and human coding at 6-8 months and 12-14 months of age predict vocabulary and phonological development at 18-20 months. Method: One-day home recordings from 20 children were collected using a LENA recorder at 6-8 months, 12-14 months, and 18-20 months. Both LENA-automated measures and measures from human coding were obtained from recordings at 6-8 months and 12-14 months. The number of different words, consonant inventory, and utterance structure inventory were identified from recordings of 18-20 months. Correlation and multiple regression analyses were performed to investigate whether measures related to early language environment and child vocalization at 6-8 months and 12-14 months were predictive of vocabulary and phonological measures at 18-20 months. Results: The results showed that the two main LENA-automated measures, conversational turn count (CTC) and child vocalization count, were positively correlated with all vocabulary and phonological measures at 18-20 months. Multiple regression analysis revealed that CTC during the prelinguistic stages was the most significant predictor of a number of different words, consonant inventory, and utterance structure inventory at 18-20 months. Also, adult word count in LENA-automated measures, child-directed speech ratio, and canonical babbling ratio measured by human coding significantly predicted some vocabulary and phonological measures at 18-20 months. Conclusion: This study highlights the multifaceted nature of language acquisition and collectively emphasizes the value of considering both quantitative and qualitative aspects of language input to understand early language development in children.

Language sample analysis (LSA) is valuable clinical tool and an important component of comprehensive language assessment. However, LSA is underutilized in real-world practice. SLPs have identified time constraints, insufficient training, and lack of confidence in LSA skills as barriers to regular LSA implementation. Communication science and disorders (CSD) programs have opportunities to provide LSA instruction to address these barriers and prepare students to reliably, feasibly, and confidently use LSA in clinical practice. This pilot study examined CSD students' perspectives on LSA instruction using the Language ENvironment Analysis System (LENA). Undergraduate students (n = 38) completed a series of two electronic surveys prior to and following LSA instruction using LENA. Changes in students' self-ratings of knowledge and skills in collecting and analyzing language samples, attitudes towards studying LSA and child language development, and critical thinking skills were assessed. Significantly higher student ratings were found for all items measuring language sampling knowledge and skills following digital LSA instruction compared to baseline. In addition, student ratings of enthusiasm for and confidence in studying LSA and child language development were also significantly higher. Students' self-ratings of critical thinking skills did not increase significantly following instruction in digital LSA. Implications for LSA teaching and learning are discussed.

Although language sample analysis (LSA) is considered an important tool for high-quality child language assessment, surveys have found that its use is quite limited by school-based speech-language pathologists (SLPs). Two of the reasons often cited are limited time and limited expertise (Kemp & Klee, 1997; Pavelko et al., 2016). This study aims to evaluate the outcomes of a language sample training program on SLP students' accuracy, efficiency, and confidence with language sample transcription and coding. Upper-division SLP undergraduates and graduate students participated in a self-paced language sample training and practice program. Participants completed online language transcription and coding training and practiced transcribing 7-10 narrative child language samples. After each one, they entered information into the quiz tool in the university's online learning management system and received automated, individualized, and specific feedback. The accuracy and time needed for the language transcriptions were recorded and analyzed. The results indicated that the participants significantly increased their accuracy and reduced the time needed for transcription and coding. They also reported a significant increase in their confidence level with language sample transcription. The results suggest that increased training and practice opportunities that involve specific feedback will better prepare new clinicians to use language sample analysis in clinical practice.

Jeremy Sawyer recounts that, after Lev S. Vygotsky's death, Jean Piaget conceded the Russian psychologist correctly understood the social origins, functions, and developmental trajectory of children's egocentric speech (now called private speech) but dismissed this work as irrelevant to children's egocentrism or nondifferentiation of perspectives. Sawyer asserts that, although Piaget precluded perspective taking in egocentric speech, a post-Vygotskian framework suggests private speech and sociodramatic play may actually promote perspective taking, thereby reducing egocentrism. In light of these assertions, Sawyer examines private speech transcripts from preschoolers for evidence of perspective taking and concludes that they suggest children internalize perspectival differences through private speech and use more implicit perspective taking than explicit mental-state terms. And preschoolers, the author suggests, employ more sociodramatic speech in a sociodramatic play context to enact imaginary scenarios and pretend roles. He concludes that, rather than a remnant of egocentrism, private speech may be a psychologicaltool for engaging multiple perspectives.

Children begin to show symptoms of neurodevelopmental disorders early on in their development. Providing early intervention that is culturally responsive to both families and the child receiving the service is vital for the child's growth. The purpose of this study was to qualitatively explore 14 Latin American Spanish-speaking parents' reactions to and perceptions of Communication Interaction Training on Autism for Spanish-speaking caregivers (CITAS), a waitlist-style parent-mediated program that focuses on teaching parents strategies to support their child's language development and enhance learning. Focus group, interview, and field note data were analyzed using the Ecological Validity Framework to determine areas of cultural fit and cultural misalignment. Notably, participants demonstrated appreciation for the CITAS program, including several specific elements that provided unique cultural fit. Some logistical and contextual challenges were also identified. Implications for research and practice are discussed.

In early childhood centres, decontextualised talk is often associated with literacy activities. In this study, however, we investigated toddler-educator conversations across various activities with a focus on those about topics that were not related to the immediate context. We examined the communicative purposes and linguistic features of these conversations and the opportunities they afford for toddlers' learning. A qualitative analysis of video-recorded conversations between 12 2-year-old toddlers and their educators resulted in identifying four kinds of talk: 'interview', 'story', 'inquiry' and 'rebuttal'. The findings reveal that toddler-educator conversations provide varied learning opportunities for toddlers, which are reinforced by both educators' and toddlers' conversational contributions. The participants' contributions are shaped by the extent to which a topic is removed from their immediate activity. These findings can inform more effective use of linguistic features, such as questions and narrative constructions, for supporting under-3-year-old children's learning and developing skills in using decontextualised talk.

Children's language development can reflect the developmental process of children's cognition and social emotions. The present study focuses on preschool children's conversational competence and narrative competence, aiming at exploring developmental features of preschool children's pragmatic competence through analyzing data from self-built oral language corpora using the INCA-A coding system and CLAN. Results show that with respect to using pragmatic indicators, frequency increases significantly with age in the dimensions of knowledge and language. In the language dimension, frequency is highest in the middle group and in the behavior dimension, frequency gradually decreases. Results are taken to indicate that preschool children's language competence improves continually, and gradually displaces the use of behavior-assisted language. Meanwhile, children can initiate conversation or discourse narration by using knowledge and language. Based on the findings, this study analyzes the development of preschool children's pragmatic competence at different ages within the framework of perlocutionary acts. Finally, corresponding educational suggestions are suggested.

This study focuses on parental use of parentese: the acoustically exaggerated, clear, and higher-pitched speech produced by adults across cultures when they address infants. While previous research shows that parentese enhances language learning and processing, it is still unclear what drives the variability in the amount of parental parentese use. We report on the development of a survey related to parental beliefs, knowledge, and self-awareness of parentese, and the cross-validation of this survey with daylong recordings in which parental parentese was measured through observation. Forty mother-father (18 monolingual English and 22 bilingual Spanish/English) U.S. families with infants between 3 and 24 months of age participated. Scores on the parentese questionnaire showed wide variability, suggesting that many parents were unsure about the effects of parentese on infant language development, and had limited self-awareness of their own parentese use. Almost half of the parents claimed that they talked to their child 'like an adult', and a similar number disagreed with the claim that parentese can support language learning. Our observational assessment of parentese demonstrated that all mothers and all fathers used parentese when talking to their infants; mothers in an average of 81% and fathers in an average of 69% of child-directed segments. Importantly, maternal parentese knowledge/beliefs scores, as well as their self-reported parentese use, were significantly positively correlated with observed parentese use; these relations were not significant for fathers. These results demonstrate that maternal and paternal links between beliefs, self-awareness, and behavior may be distinct, emphasizing the importance of studying all caregivers and using observational methodologies. More broadly, a thorough understanding of the factors that shape infants' language environments contributes to theories of language acquisition and can aid in intervention design.

In this article, the authors argue for what Édouard Glissant terms the 'right to opacity' in teaching and assessing communication and language skills in early childhood education (ECE). We draw from Glissant's writing on Relation, and his interrelated concepts of 'opacity' and 'transparency', to consider two vignettes from sensory ethnographic research conducted in ECE settings: a special education classroom and a nursery. We contest the international emphasis on efficiency, clarity, and rationality in ECE communication and language provision as one informed by colonial and ableist logics of 'transparency'. Instead, we argue for an attention to moments of what we call 'opaque reciprocity': of (1) non-dyadic, non-developmentalist, more-than-human exchange, within which (2) authorship becomes distributed inter-subjectively, thereby (3) de-emphasising efficient, clear, and rational notions of meaning-making.

The number of U.S. children living in households with extended families has greatly increased in the last 4 decades. This demographic shift calls for a reevaluation of the impact of household size on children's development. Household density (HHD), measured as the ratio of people to bedrooms in a home, has been shown to negatively relate to children's language. Here, we propose that while greater HHD may result in poorer language abilities, more adults in relation to the number of children in the home may have a positive impact on children's language. To test this hypothesis, we studied relations between HHD and adult-to-child ratio with children's vocabulary scores, as well as whether maternal education and household chaos accounted for these associations. Participants included families from a range of socioeconomic and ethnic backgrounds (N = 275; M[subscript age] = 10.85; 51% female; 51% Hispanic; annual income range less than $10,000-over $100,000). In general, higher HHD was related to lower child vocabulary scores. Conversely, higher adult-to-child ratio was related to higher child vocabulary and lower household chaos. These patterns were primarily driven by effects in Hispanic families. Our results suggest that a reevaluation of household size is needed, as more adults in the home can be protective for children's language development in larger families, an effect that may vary by culture.

Associations between home learning opportunities, parental growth mindset (the belief that intelligence is malleable), and children's academic skills have been documented primarily in European descent communities. Less is known about other communities. This study examined associations among home learning opportunities, parental mindsets, and child academic skills in a sample of 107 Latino parents and their kindergartners (M age = 67 months; 51% girls). Home learning opportunities were measured via a survey that included conventional learning practices (e.g. book sharing) and food practices (e.g. mealtime conversations). Parental mindsets were assessed through a widely used mindset scale. Child academic skills were assessed using standardized and non-standardized tests. Research Findings: Parental growth mindsets positively related to food practices ([beta] = 0.29) and there was suggestive evidence that food practices positively related to child expressive vocabulary ([beta] = 0.35). Conventional learning practices and parental growth mindset did not relate to child outcomes. Practice or Policy: If replicated in larger samples, findings suggest that Latino parents might view food practices as prime learning opportunities for their children. In addition, results suggest that food practices might foster Latino children's academic skills. Findings have the potential to inform family interventions targeting Latino families.

Research Findings: Early elementary school is a crucial time for the development of executive functions, but less is known about the impact of parent-child narratives on executive function development in children of this age group. This study aims to investigate the influence of parental scaffolding styles in parent-child co-constructed narratives in the development of transitional kindergartners' executive function. The sample comprised 35 Hispanic and non-Hispanic parent-child dyads, who were video recorded discussing a past experience at home. Video recordings were transcribed and coded for parental scaffolding strategies. Through principal component analysis, three scaffolding styles were identified: elaborative, eliciting, and echoing. Children's executive function was measured using the pencil tap task. Hierarchical linear regression analysis revealed that parents' echoing scaffolding style was positively and significantly associated with children's executive function outcomes, after controlling for child expressive language, maternal education, and parent dominant narrative languages. Practice or Policy: These findings highlight that the way parents scaffold their children's narratives can have a positive impact on their development of executive function. It also emphasizes the need for educators and practitioners to recognize the role of parent-child language interactions in supporting children's cognitive development, and to collaborate with families to promote positive developmental outcomes.

We provide an account of the developmental trajectory of Emirati Arabic negation particles. We treat the non-verbal predicate negator (NVPN) "mub" as a negative copula, in contrast to the verbal predicate negator (VPN) "maa," which encodes sentential negation in verbal and existential contexts. The analysis is supported by evidence from a longitudinal corpus of six Emirati children. Given the high frequency of occurrence of "maa" in the ambient language, we show that an input-frequency account predicts "maa-mub" substitutions in early stages of acquisition. However, confirming previous findings by Becker we show that when "mub" emerges in later stages, its distribution exhibits an asymmetry: "mub" is used frequently with individual-level nominal/adjectival predicates but it almost never appears with stage level adjectival/prepositional/ adverbial predicates, mirroring the distribution of copular elements in child English (and other languages).

The goal of this paper is to tease apart two approaches to the source of children's consistent scope assignment in negative sentences containing logical connectives: the Semantic Subset Principle and the Semantic Subset Maxim. Previous developmental work has observed that four- to six-year-old children across languages have difficulty with disjunctive interpretations in these sentences and assign conjunctive interpretations. The results of our experiment however show that Japanese children can access the disjunctive interpretations when conjunctions are elided. This finding supports the idea that children are guided by the Semantic Subset Principle when determining the default value of any parameter associated with a logical connective.

The acquisition of passives is well-studied in many languages, with evidence of crosslinguistic differences in the age at which passives are acquired. The aim of this study is to add to the existing knowledge of child acquisition of passives by providing data from Afrikaans and isiXhosa, two under-researched and typologically different languages spoken in South Africa. Comprehension and production data were collected from first language speakers (27 Afrikaans; 29 isiXhosa) from low socioeconomic backgrounds at the beginning and end of their Grade 1 year (aged 6;0 to 7;6). Picture selection and sentence completion tasks of the Receptive and Expressive Activities for Language Therapy were used to collect comprehension and production data, respectively, on short/full passives with actional verbs, reversible passives, and passives containing perceptual and psychological verbs. Comprehension of short passives with actional verbs were fully acquired by the isiXhosa L1 groups and reversible passives were approaching mastery by the beginning of Grade 1, but not the comprehension or production of any other types of passives constructions, by neither the isiXhosa nor the Afrikaans L1 group. By the end of the Grade 1 year, the isiXhosa group had acquired full comprehension and production of all passive types, whereas the Afrikaans group had fully acquired comprehension of both short and full passives with actional verbs but not yet passive production. Language group differences are thought to be related, in part, to differences in passive morphosyntax.

Modals (e.g., "can," "must") vary along two dimensions of meaning: "force" (i.e., possibility or necessity), and "flavor" (i.e., possibilities relative to knowledge [epistemic], goals [teleological], or rules [deontic] …). Comprehension studies show that children struggle with both force and flavor dimensions of modals. However, given the complex one-to-many mappings from forms to meanings, it is not clear what force or flavor children assign to the modals being tested. In this study, we use a sentence-repair task to test which modals 3- and 4-year-old children themselves prefer to produce in teleological (goal-oriented) and epistemic (knowledge-based) possibility and necessity contexts, and how these preferences differ from those of adults. Our results provide a first controlled look at which modals children use to express the major flavor and force dimensions of modal verb meanings. We shed new light on children's modal systems, and show that learners generally distinguish modal flavors but struggle distinguishing forces.

The speech register that adults especially caregivers use when interacting with infants and toddlers, that is, infant-directed speech (IDS) or baby talk, has been reported to facilitate language development throughout the early years. However, the neural mechanisms as well as why IDS results in such a developmental faciliatory effect remain to be investigated. The current study uses functional near-infrared spectroscopy (fNIRS) to evaluate two alternative hypotheses of such a facilitative effect, that IDS serves to enhance linguistic contrastiveness or to attract the child's attention. Behavioral and fNIRS data were acquired from twenty-seven Cantonese-learning toddlers 15-20 months of age when their parents spoke to them in either an IDS or adult-directed speech (ADS) register in a naturalistic task in which the child learned four disyllabic pseudowords. fNIRS results showed significantly greater neural responses to IDS than ADS register in the left dorsolateral prefrontal cortex (L-dlPFC), but opposite response patterns in the bilateral inferior frontal gyrus (IFG). The differences in fNIRS responses to IDS and to ADS in the L-dlPFC and the left parietal cortex (L-PC) showed significantly positive correlations with the differences in the behavioral word-learning performance of toddlers. The same fNIRS measures in the L-dlPFC and right PC (R-PC) of toddlers were significantly correlated with pitch range differences of parents between the two speech conditions. Together, our results suggest that the dynamic prosody in IDS increased toddlers' attention through greater involvement of the left frontoparietal network that facilitated word learning, compared to ADS.
