Purpose: We examined whether affix type and base word transparency explained variation in third- through sixth-grade students' performance on a number of morphological awareness tasks. Method: Third- through sixth-grade students (n > 500 at each grade) completed morphological awareness tasks from the Morphological Awareness Test for Reading and Spelling, which represent the ways individuals may use their morphological awareness to support reading and spelling. Explanatory item response models were used to understand the role of affix type and base word transparency on students' performance on six morphological awareness tasks. Results: For all grades, 73%-83% of variance in students' performance was due to differences across individual items. Furthermore, when task effects, affix type, and base word transparency were included simultaneously in the model, affix type was not a significant predictor; there was a significant effect of base word transparency and task. Specifically, the probability of a correct response was greater on task items in which inflected or derived words were transparent with their base word (e.g., friend > friendly) compared to items in which there was a shift in both the phonological and orthographic aspects of the base word (e.g., attend > attention). Conclusions: These findings emphasize the importance of considering base word transparency when assessing students' morphological awareness skills with less emphasis on affix type, at least for third- through sixth-grade students. Our results also point to the importance of administering a variety of morphological awareness tasks to fully capture an individual's morphological awareness skills. Collectively, researchers and practitioners should ensure assessment items on multiple measures of morphological awareness vary in their base word transparency to potentially capture a range of student performances.

Purpose: Morphological awareness is the ability to consciously manipulate the smallest units of meaning in language. Morphological awareness contributes to success with literacy skills for children with typical language and those with language impairment. However, little research has focused on the morphological awareness skills of children with speech sound disorders (SSD), who may be at risk for literacy impairments. No researcher has examined the morphological awareness skills of children with SSD and compared their skills to children with typical speech using tasks representing a comprehensive definition of morphological awareness, which was the main purpose of this study. Method: Thirty second- and third-grade students with SSD and 30 with typical speech skills, matched on age and receptive vocabulary, completed four morphological awareness tasks and measures of receptive vocabulary, real-word reading, pseudoword reading, and word-level spelling. Results: Results indicated there was no difference between the morphological awareness skills of students with and without SSD. Although morphological awareness was moderately to strongly related to the students' literacy skills, performance on the morphological awareness tasks contributed little to no additional variance to the children's real-word reading and spelling skills beyond what was accounted for by pseudoword reading. Conclusions: Findings suggest that early elementary-age students with SSD may not present with concomitant morphological awareness difficulties and that the morphological awareness skills of these students may not play a unique role in their word-level literacy skills. Limitations and suggestions for future research on the morphological awareness skills of children with SSD are discussed.

Purpose: We examined whether diverse profiles of strengths and weaknesses would emerge when assessing different aspects of morphological awareness in first- through sixth-grade students using a recently developed standardized test, the Morphological Awareness Test for Reading and Spelling (MATRS; Apel et al., 2021). Method: Four thousand fifty-nine first- through sixth-grade students completed the eight morphological awareness tasks of the MATRS. The eight tasks represent the multiple ways that morphological awareness impacts both spoken and written language skills for the English language. Exploratory finite mixture models estimated the number of latent subgroups that best reflected heterogeneity in task-level performance by grade level. Specific profiles were chosen that demonstrated strong reliability and included a set of tasks that were consistent between first- and second-grade students and between third- and sixth-grade students. Results: Different performance profiles emerged when the students completed multiple morphological awareness tasks. At each of the six grades (first through sixth), clusters of students performed differentially on specific tasks. Conclusions: The findings demonstrate that students can differ in patterns of strength and weaknesses of their morphological awareness given a range of tasks that assess different aspects of morphological awareness. The clinical implications of these findings suggest that by identifying students struggling in specific areas of morphological awareness, clinicians can develop and implement specific prescriptive instructional plans.

Purpose: As an initial step in determining whether a spelling error analysis might be useful in measuring children's linguistic knowledge, the relation between the frequency of types of scores from a spelling error analysis and children's performance on measures of phonological and orthographic pattern awareness was examined. Method: The spellings of first-grade children with typical spoken language skills were scored using the "Spelling Sensitivity System" (Masterson & Apel, 2010a); words were parsed into elements based on phonemes and then assigned a score based on the linguistic skills represented in the spelling. The children also completed more traditional measures of phonological and orthographic knowledge: an elision task and an orthographic pattern awareness task. Results: There was a moderate negative correlation between number of elements omitted in the children's spellings (e.g., the child did not represent a phoneme with a letter[s] and performance on the phonological awareness task). There also was a moderate negative correlation between frequency of orthographically based spelling errors (e.g., spelling an element with a letter[s] that could never represent that sound in English) and performance on the orthographic pattern and phonological awareness measures. Conclusions: These findings suggest that specific types of scores on the spelling error analysis provided information about the children's phonological awareness and orthographic knowledge. They also support continued investigations on the use of a systematic spelling error analysis for measuring phonological awareness and orthographic knowledge and highlight the potential utility of the analysis procedure in the educational setting.

Purpose: For non-autistic children, it is well established that linguistic awareness skills support their success with reading and spelling. Few investigations have examined whether these same linguistic awareness skills play a role in literacy development for autistic elementary school-age children. This study serves as a first step in quantifying the phonological, prosodic, orthographic, and morphological awareness skills of autistic children; how these skills compare to those of non-autistic children; and their relation to literacy performance. Method: We measured and compared the phonological, prosodic, orthographic, and morphological awareness skills of 18 autistic (with average nonverbal IQs) and 18 non-autistic elementary school-age children, matched in age, nonverbal IQ, and real-word reading. The relations between linguistic awareness and the children's word-level literacy and reading comprehension skills were examined, and we explored whether the magnitude of these relations was different for the two groups. Regression analyses indicated the relative contribution of linguistic awareness variables to performance on the literacy measures for the autistic children. Results: The non-autistic children outperformed the autistic children on most linguistic awareness measures. There were moderate-to-strong relations between performances on the linguistic awareness and literacy measures for the non-autistic children, and most associations were not reliably different from those for the autistic children. Regression analyses indicate that the performance on specific linguistic awareness variables explains unique variance in autistic children's literacy performance. Conclusion: Although less developed than those of their non-autistic peers, the linguistic awareness skills of autistic elementary school-age children are important for successful reading and spelling.

Purpose: The Pitch Patterns Test (PPT) and the Duration Patterns Test (DPT) are clinical auditory processing tests that evaluate temporal patterning skills based on pitch (PPT) or duration (DPT) aspects of sound. Although temporal patterning tests are categorized under the temporal processing domain, successful performance on the PPT also relies on accurate pitch discrimination. However, the relationship between pitch discrimination ability and temporal patterning skills has not been thoroughly evaluated. This study examined the contribution of pitch discrimination ability to performance on temporal patterning in children through the use of a pitch discrimination task and the PPT. The DPT was also given as a control measure to assess temporal patterning with no pitch component. Method: Thirty-two typically developing elementary school-age children (6;11-11;3 [years;months]) with normal hearing were given a series of three counterbalanced tasks: an adaptive psychophysical pitch discrimination task (difference limen for frequency [DLF]), the PPT, and the DPT. Results: Correlational analysis revealed moderate correlations between DLF and PPT scores. After accounting for age, results of a linear regression analysis suggested that pitch discrimination accounts for a significant amount of variance in performance on the PPT. No significant correlation was found between DLF and DPT scores, supporting the hypothesis that the pitch task had no significant temporal patterning component contributing to the overall score. Discussion: These findings indicate that pitch discrimination contributes significantly to performance on the PPT, but not the DPT, in a typically developing pediatric population. This is an important clinical consideration in both assessment and utilization of targeted therapy techniques for different clinical populations.

Purpose: Speech-language pathologists (SLPs) work with students with specific language impairment and specific learning disorder who are known to have deficits in morphological knowledge and morphological awareness. Thus, it is important that SLPs have explicit knowledge of morphology to classify, elicit, and correct morphological errors to improve these students' morphological knowledge and morphological awareness. The purposes of this clinical focus article are to summarize current evidence about SLPs and other educators' explicit knowledge of language, to identify information that supports explicit knowledge of morphology, and to illustrate the use of explicit knowledge of morphology with a hypothetical case study. Method: A case-based demonstration of an SLP's use of his/her explicit knowledge of morphology to analyze a fourth-grade student's production of derivational morphemes in a spoken language sample and on a sentence completion task is presented. Results and Conclusion: The SLP's morphological analyses and summarization of the analyses are presented.

Purpose: Spelling is a skill that relies on an individual's linguistic awareness, the ability to overtly manipulate language. The ability to accurately spell is important for academic and career success into adulthood. The spelling skills of adults have received some attention in the literature, but there is limited information regarding which approach for analyzing adults' spelling is optimal for guiding instruction or intervention for those who struggle. Thus, we aimed to examine the concurrent validity of four different scoring methods for measuring adults' spellings (a dichotomous scoring method and three continuous methods) and to determine whether adults' linguistic awareness skills differentially predict spelling outcomes based on the scoring method employed. Method: Sixty undergraduate college students who were determined to be average readers as measured by a word reading and contextual word reading task were administered a spelling task as well as morphological, orthographic, phonemic, and syntactic awareness tasks. Results: All four scoring methods were highly correlated suggesting high concurrent validity among the measures. Two linguistic awareness skills, morphological awareness and syntactic awareness, predicted spelling performance on both the dichotomous and continuous scoring methods. Contrastively, phonemic awareness and orthographic awareness predicted spelling performance only when spelling was scored using a continuous measure error analysis. Conclusions: The results of this study confirm that multiple linguistic awareness skills are important for spelling in adults who are average readers. The results also highlight the need for using continuous measures of spelling when planning intervention or instruction, particularly in the areas of orthographic and phonemic awareness.

Orthographic knowledge is the understanding of how spoken language is represented in print. However, the terms used to describe the two levels of orthographic knowledge, lexical and sublexical orthographic knowledge, have been variably defined and inconsistently measured, potentially contributing to discrepancies in research findings. Dissimilarities in how orthographic knowledge has been operationally defined and measured and the associated differences in tasks used to assess that construct are discussed. As part of that discussion, we relate how some measures assess either implicit or more explicit levels of orthographic knowledge. Using current theories and the existing research, we next provide an argument for how initial development of sublexical orthographic knowledge occurs before lexical orthographic knowledge. Suggestions are provided for what researchers might do in the future to help move the field toward a better understanding of orthographic knowledge. Strategies for assessing orthographic knowledge in literacy research are offered.

Purpose: The purpose of this study was to examine the orthographic fast-mapping abilities of 5- and 6-year-old children across time to determine (a) growth in the ability to quickly acquire mental images of written words, (b) the effect of words' statistical regularities on the learning of written word images across time, (c) whether the statistical regularities of words impact children's eye movements during an orthographic fast-mapping task, and (d) the relation among written word learning and future literacy skills. Method: Twenty-eight 5- and 6-year-old children viewed and listened to 12 short stories while their eye movements were recorded across 2 time points (approximately 3 months apart). At each time point, objects in the stories represented 12 novel pseudowords differing in their phonotactic and orthotactic probabilities. After viewing each story, the children were asked to spell and identify the target pseudowords; they also completed a battery of literacy measures. Results: The children were able to quickly acquire mental orthographic representations of the novel written pseudowords as evidenced by their ability to identify and spell the target pseudowords after viewing the stories. This ability was related to future literacy performance and significantly improved over time. Performance on the orthographic fast-mapping tasks and the children's eye movements at Time 2 were influenced by the words' linguistic properties. Conclusions: This study adds to accumulating evidence that orthographic fast-mapping is largely influenced by the orthotactic probabilities of words. These findings, taken together with those from previous investigations, provide a rich amount of evidence indicating that children are statistical learners when developing their orthographic knowledge.

This article is a report of recent evidence on methods for teaching young and struggling readers to read words. Specifically, evidence comparing synthetic and analytic phonics instruction was reviewed as well as the benefit of instruction in encoding and morphological awareness. The evidence reviewed suggests that instruction in synthetic and analytic phonics are both effective methods for teaching word reading to young and struggling readers and the inclusion of encoding in early reading instruction may provide added benefit. Furthermore, several investigations have found instruction in morphological awareness to be beneficial for improving young students' word reading. More research is needed to investigate the effectiveness of incorporating encoding and morphological awareness instruction into early reading programs.
