RESUMEN

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.

RESUMEN

PURPOSE: The word learning of preschool-age children with developmental language disorder (DLD) is improved when spaced retrieval practice is incorporated into the learning sessions. In this preregistered study, we compared two types of spacing-an expanding retrieval practice schedule and an equally spaced schedule-to determine if one of these approaches yields better word learning outcomes for the children. METHOD: Fourteen children with DLD aged 4-5 years and 14 same-age children with typical language development (TD) learned eight novel nouns over two sessions. Spacing for half of the novel words was expanded gradually during learning; for the remaining novel words, greater spacing remained at the same level throughout learning. Immediately after the second session and 1 week later, the children's recall of the words was tested. RESULTS: The children with TD recalled more novel words than the children with DLD, although this difference could be accounted for by differences in the children's standardized receptive vocabulary test scores. The two groups were similar in their ability to retain the words over 1 week. Initially, the shorter spacing in the expanding schedule resulted in greater retrieval success than the corresponding (longer spaced) retrieval trials in the equally spaced schedule. These early shorter spaced trials also seemed to benefit retrieval of the trials with greater spacing that immediately followed. However, as the learning period progressed, the accuracy levels for the two conditions converged and were likewise similar during final testing. CONCLUSION: We need a greater understanding of how and when short spacing can be helpful to children's word learning, with the recognition that early gains might give a misleading picture of the benefits that short spacing can provide to longer term retention.

RESUMEN

This paper evaluates an innovative framework for spoken dialect density prediction on children's and adults' African American English. A speaker's dialect density is defined as the frequency with which dialect-specific language characteristics occur in their speech. Rather than treating the presence or absence of a target dialect in a user's speech as a binary decision, instead, a classifier is trained to predict the level of dialect density to provide a higher degree of specificity in downstream tasks. For this, self-supervised learning representations from HuBERT, handcrafted grammar-based features extracted from ASR transcripts, prosodic features, and other feature sets are experimented with as the input to an XGBoost classifier. Then, the classifier is trained to assign dialect density labels to short recorded utterances. High dialect density level classification accuracy is achieved for child and adult speech and demonstrated robust performance across age and regional varieties of dialect. Additionally, this work is used as a basis for analyzing which acoustic and grammatical cues affect machine perception of dialect.

RESUMEN

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.

RESUMEN

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. SUPPLEMENTAL MATERIAL: https://doi.org/10.23641/asha.25521400.

RESUMEN

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.

RESUMEN

Lexical alignment, a communication phenomenon where conversational partners adapt their word choices to become more similar, plays an important role in the development of language and social communication skills. While this has been studied extensively in the conversations of preschool-aged children and their parents in Western, Educated, Industrialized, Rich, and Democratic (WEIRD) communities, research in other pediatric populations is sparse. This study makes significant expansions on the existing literature by focusing on alignment in naturalistic conversations of school-aged children from a non-WEIRD population across multiple conversational tasks and with different types of adult partners. Typically developing children aged 5 to 8 years (n = 45) engaged in four semi-structured conversations that differed by task (problem-solving vs. play-based) and by partner (parent vs. university student), resulting in a corpus of 180 conversations. Lexical alignment scores were calculated and compared to sham conversations, representing alignment occurring at the level of chance. Both children and adults coordinated their conversational utterances by re-using or aligning each other's word choices. This alignment behavior persisted across conversational tasks and partners, although the degree of alignment was moderated by the conversational context. These findings suggest that lexical alignment is a robust phenomenon in conversations between school-age children and adults. Furthermore, this study extends lexical alignment findings to a non-WEIRD culture, suggesting that alignment may be a coordination strategy employed by adults and children across diverse linguistic and cultural backgrounds.

RESUMEN

PURPOSE: The study examined the use of percent grammatical utterances (PGUs) for assessing grammatical skills in Mandarin-speaking 3-year-old children. METHOD: Participants were 30 Mandarin-speaking 3-year-olds with typical development. Language samples were collected in two visits for each child using a picture description task. Children were asked to talk about 16 pictures in response to questions and prompts at each visit. Pictures for the language sample collection were identical across the visits. PGUs were computed, and the grammatical errors that children produced in the task were coded and tallied for error types at each visit. Test-retest reliability, split-half reliability, and concurrent criterion validity of PGUs were evaluated. RESULTS: The mean PGU level was approximately 78% at Visit 1 and 81% at Visit 2, both of which were significantly below the mastery level (i.e., 90%). The correlation coefficient for test-retest reliability of PGU was large (r = .70, p < .01); the correlation coefficient for split-half reliability was medium at Visit 1 (r = .47, p < .01) and large (r = .65, p < .01) at Visit 2. In addition, the correlation coefficient for concurrent criterion validity of PGU was medium for both visits (rs ≥ .35, ps ≤ .03). The ranking and proportion of each error type were similar between the visits. CONCLUSION: The initial evidence from psychometric properties suggests that PGU computed from the picture description task is a reliable and valid measure for evaluating grammatical skills in Mandarin-speaking 3-year-old children.

RESUMEN

PURPOSE: Across Canada, speech-language pathologists (SLPs) and educational psychologists (EPs) work in schools to identify and diagnose childhood learning difficulties, including language disorders; however, both professional groups use different terms to identify and diagnose them. Using the term developmental language disorder (DLD), developed by the CATALISE consortium, would provide consistency across fields. To effectively implement the use of DLD, it is crucial to understand how EPs and SLPs currently identify childhood language disorders and to investigate the potential impact of a practice change in this area. METHOD: The study conducted 13 moderated focus groups and one one-on-one semistructured interview across six Canadian provinces in English and French. RESULTS: We found some social and structural barriers that impact SLPs' and EPs' current practice of identifying and diagnosing language disorders generally (e.g., the belief that children should not be labeled "too early," institutions that prioritize certain professional diagnoses over others, board policies that do not allocate funds for language disorders, professionals' reticence to convey difficult information such as a diagnosis to collaborators) and DLD specifically (e.g., different professional taxonomies, lack of familiarity with or uncertainty about the label, not recognized as a condition in schools that may or may not even identify language disorder as a category of exceptionality). Nevertheless, the focus groups also revealed the extent to which DLD could be useful in their current practice. CONCLUSION: Both EPs and SLPs acknowledged the importance of working together; therefore, DLD could inspire more collaborative practice between SLPs and EPs around language disorders.

RESUMEN

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.

RESUMEN

PURPOSE: Despite the speed with which telehealth use advanced during the COVID-19 pandemic, evidence is needed to support the remote delivery of standardized assessments. This study investigated the reliability and feasibility of administering a standardized language assessment administered in real-world telehealth scenarios compared to in-person administration. METHOD: A total of 100 children between the ages of 3 and 12 years were administered one of three versions of the Clinical Evaluation of Language Fundamentals (CELF). Children were administered the CELF by the same licensed speech-language pathologists (SLPs) in person and using telehealth, with the order counterbalanced. Means for Core Language standard scores were compared between conditions and among devices. Descriptive statistics summarized the behavior and technology disruptions during administration as well as the results of parent and SLP telehealth perception surveys. RESULTS: In-person and telehealth mean scores on all three versions of the CELF revealed no systematic differences of one condition under- or overestimating another. The incidence of child behavior disruptions was similar for both test administration conditions. Adaptations compensated for the rare technology disruptions. Despite no significant language score and behavior differences between testing conditions, parents reported they continued to prefer in-person assessments. SLP participants viewed telehealth overall positively but identified conditions in which they continued to prefer in-person delivery. CONCLUSIONS: This study provides evidence of minimal or no differences in scores and behavioral or technological disruptions between remote and in-person administration of the CELF core language assessments. SLP and parent participants' attitudes toward remote delivery of standardized tests appear to be evolving in a positive direction compared to previous studies.

RESUMEN

Based on the linguistic analysis of game explanations and retellings, the paper's goal is to investigate the relation of preschool children's situated discourse competence and iconic gestures in different communicative genres, focussing on reinforcing and supplementary speech-gesture-combinations. To this end, a method was developed to evaluate discourse competence as a context-sensitive and interactively embedded phenomenon. The so-called GLOBE-model was adapted to assess discourse competence in relation to interactive scaffolding. The findings show clear links between the children's competence and their parents' scaffolding. We suggest this to be evidence of a fine-tuned interactive support system. The results also indicate strong relations between higher discourse competence and increased frequency of iconic gestures. This applies in particular to reinforcing gestures. The results are interpreted as a confirmation that the speech-gesture system undergoes systematic changes during early childhood, and that gesturing becomes more iconic - and thus more communicative - when discourse competence is growing.

RESUMEN

PURPOSE: The purpose of this study was to investigate the diagnostic accuracy of two measures derived from spontaneous language samples, mean length of utterance in words (MLUw) and percentage of grammatical utterances (PGU), in identifying developmental language disorder (DLD) in Spanish-English bilingual children. We examined two approaches: best language and total language. METHOD: The participants in this study included 74 Spanish-English bilingual children with (n = 36) and without (n = 38) DLD. Language samples were elicited through a story retell and story generation task using Frog wordless picture books in English and Spanish. Stories were transcribed and coded using the Systematic Analysis of Language Samples (Miller & Iglesias, 2020) to extract MLUw and PGU in both languages. RESULTS: Logistic regression analyses suggested that a model that included PGU, MLUw, and age achieved the best diagnostic accuracy in predicting group membership. Both approaches, best language and total language, had fair diagnostic accuracy. CONCLUSIONS: In combination, PGU and MLUw seem to be useful diagnostic tools to differentiate bilingual children with and without DLD. Clinical implications and usability are discussed.

RESUMEN

PURPOSE: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. METHOD: One hundred nine children were recorded during free-play at 2;6 and 3;11 (years;months). We compared MLU in syllables, morphemes, and words (MLUw) in transcripts of different lengths (50, 75, 100, and all available utterances). For evaluating the validity of MLU, we also calculated Index of Productive Syntax (IPSyn) and number of different words (NDW) and used results of receptive vocabulary and grammar comprehension tests. RESULTS: The different MLU measures based on different sample lengths correlated closely with MLU in transcripts of all utterances (all rs > .87). We found mostly strong correlations between MLU, IPSyn, and NDW at both time points and weak or moderate correlations between MLU and grammar and vocabulary. Regression models showed the significant unique effect of MLUw at 2;6 for MLUw (ß = .29) and grammar (ß = .33) at 3;11 and vocabulary (ß = .27) at 3;7. CONCLUSION: MLUw based on all utterances was confirmed as a valid measure of early language skills in Czech, as it is stable in time and shows concurrent and predictive relations with other transcript-based and test-based measures.

RESUMEN

PURPOSE: We investigated the impact of narrative task complexity on macrostructure in both languages of bilingual kindergarten children and the relationship of macrostructure across languages to guide practitioners' choice of assessment tools and aid in interpretation of results. METHOD: Thirty-nine English-Hebrew bilingual kindergarten children (Mage = 65 months) retold two narratives in each language: a one-episode story and a three-episode story. Stories were coded for macrostructure using five story grammar (SG) elements: Internal State-Initiating Event, Goal, Attempt, Outcome, and Internal State-Reaction. Linear mixed and generalized linear mixed models were used to analyze scores for total macrostructure, episode, and SG elements; correlations were conducted to examine cross-language relations in macrostructure. RESULTS: In general, performance on the single-episode story was significantly better than for the three-episode story: higher percentages of SG elements were produced, with better performance in the home language/English. In addition to Task and Language effects, Age and Episode (Episodes 1/2/3 of the three-episode story vs. one-episode story) emerged as predictors of macrostructure. Performance on the different episodes of the three-episode story varied, with Episode 3 yielding scores similar to those on the one-episode story. Children produced more Attempts and Outcomes than other SG elements. Finally, the total macrostructure scores yielded low to moderate correlations across languages for both one-episode and three-episode stories, but there were no significant cross-task (one-episode/three-episode story) correlations. CONCLUSIONS: The study illustrates the importance of task complexity in narrative performance. Ideally, assessment should include a variety of tools, which would include narratives varying in complexity. However, time constraints do not always permit this luxury. The findings here may offer more to therapists than to diagnosticians. Narratives should be manipulated for episodic complexity not only in the number of episodes but also with regard to characters, goals, feelings, and reactions to events.

RESUMEN

PURPOSE: Interactions with caregivers during the ordinary activities that occur as families go about their everyday lives are critical to supporting children's acquisition of social communication and language skills. The purpose of this study was to examine child communication and parent verbal responsiveness across interaction contexts in 211 children (Mage = 20 months) on the autism spectrum (n = 121), with developmental delay (n = 46), or with typical development (n = 44). METHOD: Families participated in up to eight activities during an hour-long, video-recorded home observation. We tested differences in the strength of associations between diagnostic group and interaction context using linear mixed-effects models, with child rate per minute of communication and proportions of parent follow-in comments and directives as outcome variables. Child communicative functions expressed across contexts were also examined. RESULTS: Children across groups communicated at significantly higher rates per minute during book sharing and play with people compared to other interaction contexts. Most child communication was for the function of joint attention during book sharing, for social interaction during play with people, and for behavior regulation during necessary activities such as family chores and meals. On average, parents of children responded using proportionally more follow-in comments during book sharing and play compared to necessary activities, during which parents used more follow-in directives. CONCLUSION: Results provide a glimpse into the dyadic communication that may occur within everyday activities at home, which supports the need for future intervention research and may aid clinicians seeking to identify activities that serve as important contexts for intervention.

RESUMEN

PURPOSE: This review aims to comprehensively summarize, compare, and evaluate screeners used to identify risk for developmental language disorder (DLD), a common learning disability that is underidentified. Screening for DLD is a cost-effective way to identify children in need of further assessment and, in turn, provides much needed supports. METHOD: We identified 15 commercially available English language DLD screeners in North America. We then characterized each screener on 27 aspects in three domains, including (a) accessibility information (acronym, subtest, website, cost, materials included, publish year, examiner qualification, age range, administration time, and administration format), (b) usability features (dialect compatibility, progress monitoring function, actionable follow-up instruction, group assessment capability, and online administration availability), and (c) technical standards (the availability of a technical manual, conceptual definition, the sample size used in classification accuracy calculation, sample distribution, year of sample collection, outcome measure, sample base rate, cutoff score, sensitivity, specificity, positive predictive value, and negative predictive value). RESULTS: We obtained sufficient accessibility information from 14 out of 15 (93%) screeners. In contrast, none of the screeners (0%) included comprehensive usability features. Ten screeners (67%) included a range of classification accuracy (70%-100% sensitivity and 68%-90% specificity). We provided areas of strength and weakness for each screener as a quick reference for users and generated screener recommendations for five practical scenarios. CONCLUSIONS: Our findings presented some DLD screeners that meet most standards and highlight numerous areas for improvement, including improving classification accuracy and clarifying follow-up instructions for children who are identified with DLD risk. Screening for DLD is critical to provide timely early identification, intervention, and classroom support, which in turn facilitates student outcomes.

RESUMEN

OBJECTIVE: This study aimed to develop a Digital Speech Assessment Instrument to evaluate the phonological and motor speech skills of Brazilian Portuguese-speaking children and adolescents through six tasks: (a) word naming, (b) word imitation, (c) pseudoword imitation, (d) word repetition, (e) pseudoword repetition, and (f) diadochokinesis. METHOD: The assessment instrument was developed and validated in a seven-step process, beginning with stimulus selection and ending with Pilot Study 1 (involving children and adolescents with typical speech development) and Pilot Study 2 (involving children and adolescents with speech sound disorders [SSDs]). Participants of the study included expert and nonexpert judges, children, and adolescents. RESULTS: The Digital Speech Assessment Instrument contains 91 real words (61 in the naming task, 51 in the imitation task, and five in the repetition task), 26 pseudowords (26 in the imitation task and four in the repetition task), and six stimuli for diadochokinesis. The test contains stimuli in the form of images as well as audio and video recordings and allows for the analysis and storage of participant data in a virtual database. CONCLUSIONS: This study described the development of the Digital Speech Assessment Instrument, available in Brazilian Portuguese for the evaluation of several aspects of speech production (including word and pseudoword naming, imitation, and repetition and diadochokinesis). The test was developed for children aged 2;0 (years;months) to 17;11 and is administered fully online. In the future, the instrument can be used to provide a timely and accurate diagnosis of SSDs.
