RESUMEN

INTRODUCTION: Language sampling is a widely used means of language assessment; it is based on the collection and transcription of a child's language production in various communicative contexts. The need for social distancing due to the COVID-19 pandemic impacted language sampling and speech and language therapy services in general. The in-person assessment became extremely challenging leading to the immediate increased use of telepractice in speech and language therapy. This scoping review aimed to identify the use of telepractice for language sampling in speech and language therapy during the COVID-19 pandemic. METHODS: A scoping review of existing literature was performed to collect evidence on using language sample collection via telepractice. A database search was conducted in PubMed, PsycINFO, Cochrane Library, Mendeley, Electronic, and grey bibliography in 2022. Articles were included if they met the inclusion criteria. The quality of each selected study was assessed using the modified critical appraisal skills program (CASP) checklist. RESULTS: Systematic searches identified 51 studies with six studies in total meeting the inclusion criteria. The results showed that telepractice was a necessary tool during the pandemic of COVID-19 to conduct language sampling in speech and language assessment. CONCLUSION: Speech and language therapists (SLTs) effectively collected language samples through telepractice during the COVID-19 pandemic. Although, to date, the literature on language sampling via telepractice is limited. The need for SLTs to rely on telepractice for language sampling warrants further investigation.

RESUMEN

Prior research supports the use of natural language sampling (NLS) to assess the rate of speech utterances (URate) and the rate of conversational turns (CTRate) in minimally verbal (MV) autistic children. Bypassing time-consuming transcription, previous work demonstrated the ability to derive URate and CTRate using real-time coding methods and provided support for their strong psychometric properties. (1) Unexplored is how URate and CTRate using real-time coding methods capture change over time and (2) whether specific child factors predict changes in URate and CTRate in 50 MV autistic children (40 males; M = 75.54, SD = 16.45 (age in months)). A NLS was collected at Time 1 (T1) and Time 2 (T2) (4.5 months between T1 and T2) and coding was conducted in ELAN Linguistic Annotator software using a real-time coding approach to derive URate and CTRate. Findings from paired samples Wilcoxon tests revealed a significant increase in child URate (not examiner URate) and child and examiner CTRate from T1 to T2. Child chronological age, Mullen expressive language age equivalent scores, and URate and CTRate at T1 were predictive of URate and CTRate at T2. Findings support using NLS-derived real-time coded measures of URate and CTRate to efficiently capture change over time in MV autistic children. Identifying child factors that predict changes in URate and CTRate can help in the tailoring of goals to children's individual needs and strengths.

RESUMEN

Narratives skills are associated with long-term academic and social benefits. While students with disabilities often struggle to produce complete and complex narratives, it remains unclear which aspects of narrative language are most indicative of disability. In this study, we examined the association between a variety of narrative contents and form indices and disability. Methodology involved drawing 50 K-3 students with Individual Education Programs (IEP) and reported language concerns from a large diverse sample (n = 1074). Fifty typically developing (TD) students were matched to the former group using propensity score matching based on their age, gender, grade, mother's education, and ethnicity. Narrative retells and generated language samples were collected and scored for Narrative Discourse and Sentence Complexity using a narrative scoring rubric. In addition, the number of different words (NDW), subordination index (SI), and percentage of grammatical errors (%GE) were calculated using computer software. Results of the Mixed effect model revealed that only Narrative Discourse had a significant effect on disability, with no significant effect revealed for Sentence Complexity, %GE, SI, and NDW. Additionally, Narrative Discourse emerged as the sole significant predictor of disability. At each grade, there were performance gaps between groups in the Narrative Discourse, Language Complexity, and SI. Findings suggest that difficulty in Narrative Discourse is the most consistent predictor of disability.

RESUMEN

Background: Although parental checklists are well-known for their potential in indexing young children's lexicon size, they can also be used to track children's acquisition of individual words. Word-level data can be used to identify the checklist words most and least commonly employed across groups of children. Like parent-completed vocabulary checklists, samples of spontaneous language use collected from multiple children can also generate measures of word commonality, concerned with the numbers of children producing individual words. To our knowledge, comparisons of word usage as determined by parental checklist and language sample data obtained in parallel from the same children have not been carried out. Also scarce in the empirical literature are item-level analyses of early bilingual lexicons that explore word usage across two emerging languages. The present study aimed to contribute toward bridging both gaps through the analysis of data generated by a bilingual Maltese-English adaptation of the vocabulary checklist of the MacArthur Communicative Development Inventories: Words and Sentences (CDI: WS) and spontaneous language samples for the same children. An additional objective was to derive implications for revising the current version of the vocabulary checklist, in preparation for its eventual standardization. Materials and methods: For 44 Maltese children aged 12, 18, 24, and 30 months, the words reported by their main caregivers on the vocabulary checklist were identified, along with their respective semantic categories. For the same children, 20-min language samples obtained during free play with the caregiver were transcribed orthographically. Words identified through parental report and language sampling were analyzed for commonality, i.e., the number of children producing each word. Results: Comparison of the word usage patterns obtained through both methods indicated differences in the words most commonly sampled and those most commonly reported, particularly in relation to grammatical categories. Notwithstanding these differences, positive and significant correlations emerged when considering all grammatical categories and languages across commonality levels. Discussion: The commonality scores based on parental checklist data have implications for reconsidering the length and language balance of the Maltese-English adaptation of the CDI: WS vocabulary checklist. Sampled word usage patterns can contribute additional objectivity in updating the reporting instrument in preparation for its eventual standardization.

RESUMEN

INTRODUCTION: It has been well established that the function of sharing personal narratives is to inform the listener about what the event meant to the narrator, for example, by using a range of evaluative devices. The use of these evaluative devices may reflect a person's understanding of the differences between one's own mind and others, by expressing their beliefs, emotions, thoughts, and desires. This paper investigates children's use of evaluative devices when producing personal narratives in response to the six emotion-based prompts contained in the Global TALES protocol (excited, worried, annoyed, proud, problem situation, something important). It addresses three research questions: (1) What types and proportions of evaluative devices do 10-year-old English-speaking children use in response to the six prompts contained in the Global TALES protocol and are there differences in performance between boys and girls? (2) What are the correlations between the different types of evaluative devices? (3) Does children's use of evaluative devices differ depending on the type of prompt used? METHODS: Eighty-two native English-speaking ten-year-old children from three English-speaking countries (Australia, New Zealand, and the USA) participated. None of the children had been identified with language and/or learning difficulties. Children's personal narratives were transcribed and analysed for the use of 12 evaluative devices: compulsion, internal emotional states, evaluative words, intensifiers, mental states, causal explanations, hypotheses, objective judgements, subjective judgements, intent, negatives, and repetition. RESULTS: Results showed that children use a high number of evaluative devices, with "intensifiers" and "evaluative words" used most frequently. There were few effects for sex, apart from girls using a wider range of evaluative devices than boys. We found moderate to large correlations between most devices, with factor analysis revealing three factors we labelled "causality," "hypothesis," and "judgement." Although there were significant overall effects for prompt type on the use of evaluative devices, there was no clear pattern when inspecting responses to individual prompts. CONCLUSION: The results from this study shed light on children's use of evaluative devices to convey the meaning of their personal narratives in response to six different prompts tapping into different emotions. Moving beyond appraising children's structural language skills when narrating their personal experiences may enhance the understanding of interpersonal and intrapersonal aspects of theory of mind, which may inform clinical practices, such as individualized goal setting and intervention choices.

RESUMEN

INTRODUCTION: This small-scale study explored the feasibility of the Global TALES protocol in eliciting personal narratives in typically developing monolingual Irish children, using the online Zoom platform. We investigated children's performance on measures of productivity (total number of utterances; total number of words) and syntactic complexity (MLU in words). We also documented the topics children talked about in response to the six emotion-based prompts contained in the Global TALES protocol. METHODS: Nineteen typically developing children (6 male, 13 female), aged between 10.0 and 10.11 years produced personal narratives in response to the Global TALES protocol. Given COVID-19 pandemic-related public health restrictions, the language samples were elicited using Zoom. All stories were transcribed and analysed using Systematic Analysis of Language Transcripts software. Qualitative content analysis was used to code the topics of the children's stories. RESULTS: Sixteen participants responded to all prompts. One participant only responded to three of the six prompts. The prompt that was least successful in eliciting a response was the "problem" prompt; 15.7% (n = 3) of the children did not provide a response to this prompt. On average, children produced 40 utterances, although individual variability was high. On average, MLU was 8.7, ranging from 6 to 11. Children's topics closely resembled those reported in the Global TALES feasibility study despite the fact, the current study took place during the COVID-19 pandemic. The most frequent topics were related to family (events, illnesses, relationships, siblings) and finding or fixing something. CONCLUSION: The Global TALES protocol was successful in eliciting personal narratives from 10-year-old Irish English-speaking children. Future larger scale studies are now needed to investigate if the results generalise to the wider Irish population with a view to create local benchmarks of personal narrative performance.

RESUMEN

Natural Language Sampling (NLS) offers clear potential for communication and language assessment, where other data might be difficult to interpret. We leveraged existing primary data for 18-month-olds showing early signs of autism, to examine the reliability and concurrent construct validity of NLS-derived measures coded from video-of child language, parent linguistic input, and dyadic balance of communicative interaction-against standardised assessment scores. Using Systematic Analysis of Language Transcripts (SALT) software and coding conventions, masked coders achieved good-to-excellent inter-rater agreement across all measures. Associations across concurrent measures of analogous constructs suggested strong validity of NLS applied to 6-min video clips. NLS offers benefits of feasibility and adaptability for validly quantifying emerging skills, and potential for standardisation for clinical use and rigorous research design.

RESUMEN

Purpose: A narrative is a reliable tool for assessing the child's oral language. There are various narrative assessment tools. Most of them follow the Language Sample Analysis method such as Systematic Analysis of Language Transcripts (SALT) which is time-consuming and needs extensive training. The Narrative Assessment Protocol (NAP) offers a free and faster method of assessment to administer. The current study compared the NAP online and offline coding methods.Methods: Fifty-two kindergarteners (40-66 months old) were voice-recorded while generating a story. A transcriber coded the samples using both online and offline methods. Then, relative and absolute reliabilities were measured.Results: The results indicate a high correlation between the NAP offline and online scoring methods. Aside from a few items, both methods showed good correlations with each other.Conclusions: The NAP online coding method can be used as an alternative to an offline transcription to obtain a quick picture of a child's microstructure measures in narration.

RESUMEN

Oral narrative abilities are an important measure of children's language competency and have predictive value for children's later academic performance. Research and development underway in New Zealand is advancing an innovative online oral narrative task. This task uses audio recordings of children's story retells, speech-to-text software and language analysis to record, transcribe, analyse and present oral narrative and listening comprehension data back to class teachers. The task has been designed for class teachers' use with the support of SLP or literacy specialists in data interpretation. Teachers are upskilled and supported in order to interpret these data and implement teaching practices for students through online professional learning and development modules, within the context of a broader evidence-based approach to early literacy instruction. This article describes the development of this innovative, culturally relevant, online tool for monitoring children's oral narrative ability and listening comprehension in their first year of school. Three phases of development are outlined, showing the progression of the tool from a researcher-administered task during controlled research trials, to wide-scale implementation with thousands of students throughout New Zealand. The current iteration of the tool uses an automatic speech-recognition system with specifically trained transcription models and support from research assistants to check transcription, then code and analyse the oral narrative. This reduces transcription and analysis time to ~7 min, with a word error rate of around 20%. Future development plans to increase the accuracy of automatic transcription and embed basic language analysis into the tool, with the aim of removing the need for support from research assistants.

RESUMEN

Expressive language sampling (ELS) is a frequently used tool for language analysis, as it can be used across widely ranging cognitive and language abilities. ELS can also evaluate pragmatic language, including excessive self-repetition, which is challenging to assess with traditional standardized assessments. This study explored how a well-established ELS protocol can assess three types of linguistic self-repetition in three neurodevelopmental disabilities: fragile X syndrome (FXS), autism spectrum disorder (ASD), and Down syndrome (DS). We examined its ability to differentiate between these disorders, the relationships between repetitive language and other participant characteristics, and initial construct validity. We found that the groups with FXS and ASD differed significantly on each of the three repetitive language measure, and that the group with DS differed from either ASD or FXS on two. Cognitive ability was significantly related to phrase repetition in the group with ASD. When the groups were combined, there was evidence of convergent and divergent validity. This study extends previous research on ELS and supports its use as a means to characterize pragmatic language. It also provides information about the relationships between repetitive language and other phenotypic characteristics.

RESUMEN

Children with autism spectrum disorder (ASD) have conversation deficits, yet the growth of conversation abilities is understudied, especially in Chinese-speaking populations. Little is known about whether their parents' verbal responsiveness and redirectives are related to their conversation skills. Children with ASD (N = 37; M = 5;5) and their parents contributed their language samples. These children interacted with their parents at four time points over nine months. The number of conversational turns and the proportion of child-initiated conversation (but not the proportion of children's appropriate responses) grew over nine months. After controlling for time, autism severity, and language skills, parents' verbal responsiveness positively predicted children's appropriate responses. Parents' redirectives negatively predicted the proportion of children's appropriate responses and the number of conversational turns.

RESUMEN

BACKGROUND: The purpose of this study was to evaluate expressive language sampling (ELS) as a procedure for generating spoken language outcome measures for treatment research in Down syndrome (DS). We addressed (a) feasibility, (b) practice effects across two short-term administrations, (c) test-retest reliability across two short-term administrations, (d) convergent and discriminant construct validity, and (e) considered comparisons across the conversation and narration contexts. METHOD: Participants were 107 individuals with DS between 6 and 23 years of age who presented with intellectual disability (IQ < 70). The utility of ELS procedures designed to collect samples of spoken language in conversation and narration were evaluated separately. Variables of talkativeness, vocabulary, syntax, utterance planning, and articulation quality, derived from transcripts segmented into C-units (i.e., an independent clause and its modifiers), were considered. A 4-week interval was used to assess practice effects and test-retest reliability. Standardized direct assessments and informant report measures were collected to evaluate construct validity of the ELS variables. RESULTS: Low rates of noncompliance were observed; youth who were under 12 years of age, had phrase-level speech or less, and had a 4-year-old developmental level or less were at particular risk for experiencing difficulty completing the ELS procedures. Minimal practice effects and strong test-retest reliability across the 4-week test-retest interval was observed. The vocabulary, syntax, and speech intelligibility variables demonstrated strong convergent and discriminant validity. Although significant correlations were found between the variables derived from both the conversation and narration contexts, some differences were noted. CONCLUSION: The ELS procedures considered were feasible and yielded variables with adequate psychometric properties for most individuals with DS between 6 and 23 years old. That said, studies of outcome measures appropriate for individuals with DS with more limited spoken language skills are needed. Context differences were observed in ELS variables suggest that comprehensive evaluation of expressive language is likely best obtained when utilizing both contexts.

RESUMEN

Language impairments are frequent, severe, and of prognostic value in autism spectrum disorder (ASD). Unfortunately, the evaluation of the efficacy of treatments targeting the language skills of those with ASD continues to be hindered by a lack of psychometrically sound outcome measures. Expressive Language Sampling (ELS) procedures offer a promising alternative to norm-referenced standardized tests for assessing expressive language in treatment studies. Until now, however, research on the validity and utility of ELS as outcome measures has been limited to administrations by a trained professional in a clinic setting and to use with English-speaking families. These limitations are a barrier for many families accessing the benefits of participation in treatment studies. The current study examines the feasibility of teaching native English-speaking parents (NESP) and native Spanish-speaking parents (NSSP) how to administer the ELS narrative task (ELS-N) to their sons and daughters with ASD (between ages 6 and 21) at home through telehealth-delivered procedures. The parent training was provided in the primary language of the participating parent (i.e., 11 NSSP and 11 NESP) and administered by the parent to the youth in the language that the parent reported to use to communicate with the youth at home (i.e., 9 Spanish and 13 English). Families were able to choose between using their own technology or be provided with the technology needed for participation. Of the 19 parents who completed the training, 16 learned to administer the ELS-N procedures. In addition, strong test-retest reliability and no practice effects over the 4-week interval were observed for ELS-N derived youth outcome measures (i.e., talkativeness, vocabulary, syntax, dysfluency, and intelligibility) for both NSSP and NESP. Results from this pilot study suggest that the home-based parent-implemented ELS-N procedures can be learned and administered at acceptable levels of fidelity by parents, with good test-retest reliability and limited practice effects observed in terms of outcome measures for youth with ASD. Implications for treatment studies and future directions are discussed.

RESUMEN

BACKGROUND: The purpose of this study was to conduct a 20-week controlled trial of lovastatin (10 to 40 mg/day) in youth with fragile X syndrome (FXS) ages 10 to 17 years, combined with an open-label treatment of a parent-implemented language intervention (PILI), delivered via distance video teleconferencing to both treatment groups, lovastatin and placebo. METHOD: A randomized, double-blind trial was conducted at one site in the Sacramento, California, metropolitan area. Fourteen participants were assigned to the lovastatin group; two participants terminated early from the study. Sixteen participants were assigned to the placebo group. Lovastatin or placebo was administered orally in a capsule form, starting at 10 mg and increasing weekly or as tolerated by 10 mg increments, up to a maximum dose of 40 mg daily. A PILI was delivered to both groups for 12 weeks, with 4 activities per week, through video teleconferencing by an American Speech-Language Association-certified Speech-Language Pathologist, in collaboration with a Board-Certified Behavior Analyst. Parents were taught to use a set of language facilitation strategies while interacting with their children during a shared storytelling activity. The main outcome measures included absolute change from baseline to final visit in the means for youth total number of story-related utterances, youth number of different word roots, and parent total number of story-related utterances. RESULTS: Significant increases in all primary outcome measures were observed in both treatment groups. Significant improvements were also observed in parent reports of the severity of spoken language and social impairments in both treatment groups. In all cases, the amount of change observed did not differ across the two treatment groups. Although gains in parental use of the PILI-targeted intervention strategies were observed in both treatment groups, parental use of the PILI strategies was correlated with youth gains in the placebo group and not in the lovastatin group. CONCLUSION: Participants in both groups demonstrated significant changes in the primary outcome measures. The magnitude of change observed across the two groups was comparable, providing additional support for the efficacy of the use of PILI in youth with FXS.

RESUMEN

Although pragmatic speech impairments have been found across the autism spectrum, how these manifest in minimally verbal (MV) individuals with autism spectrum disorder (ASD) has not been studied. We compared the pragmatic speech profiles of MV (n = 50) and verbally fluent (VF) individuals with ASD (n = 50; 6-21 years-old) based on natural language sampling during the Autism Diagnostic Observation Schedule-2. MV individuals with ASD primarily used their speech to agree/acknowledge/disagree, respond to a question, and request. In contrast, the primary pragmatic function used by VF individuals was commenting. Out of the total non-echolalic speech, groups did not differ proportionally in labeling and response to questions. Findings highlight the importance of investigating multiple aspects of pragmatic communication across different conversational partners and contexts.

RESUMEN

Language impairment is a core difficulty in fragile X syndrome (FXS), and yet standardized measures lack the sensitivity to assess developmental changes in the nature of these impairments. Expressive Language Sampling Narrative (ELS-N) has emerged as a promising new measure with research demonstrating its usefulness in a wide range of ages in developmental disabilities and typical development. We examined ELS-N results in FXS and age-matched typically developing (TD) controls along with cognitive, adaptive, and clinical measures. We found the groups differed significantly on all ELS-N variables. Cognitive abilities were related to lexical diversity, syntactic complexity, and unintelligibility for the FXS group, but only verbal abilities were related to syntactic complexity in TD. Autism spectrum disorder (ASD) symptomatology was related to less intelligibility in speech. Measures of hyperactivity were related to increased talkativeness and unintelligibility. In addition, FXS males in comparison to FXS females were more impaired in cognitive ability, ASD symptoms, hyperactivity, and anxiety. This study extends the previous ELS research, supporting its use in FXS research as a measure to characterize language abilities. It also demonstrates the relationships between ELS-N variables and measures of cognitive, adaptive, ASD symptoms, and clinical symptoms.

RESUMEN

Background and aims: Understanding the unique expressive language profiles of children with phenotypically similar, but distinct neurodevelopmental disorders, such as idiopathic autism spectrum disorder and fragile X syndrome with a co-diagnosis of autism spectrum disorder (fragile X syndrome + autism spectrum disorder), has both clinical and theoretical implications. However, comparative studies of these two clinical groups have been limited, and results have been inconsistent, partially as a result of different assessment methods being utilized. Thus, the current study compared the expressive language profiles of boys with idiopathic autism spectrum disorder and boys with fragile X syndrome + autism spectrum disorder and examined whether a similar linguistic profile emerged across different language sampling contexts: a semi-structured conversation and the Autism Diagnostic Observation Schedule. Methods: Eighteen boys with autism spectrum disorder (Mage = 13.25 years) and 19 boys with fragile X syndrome + autism spectrum disorder (Mage = 12.19 years), matched on autism spectrum disorder symptom severity and similar in terms of chronological age and mean length of utterance, participated in this study. Boys produced two language samples: one semi-structured conversation and one taken from the Autism Diagnostic Observation Schedule. Language samples were coded for talkativeness, lexical diversity, mean length of utterance, intelligibility, and repetitive or perseverative language. Results: Analyses revealed that boys with autism spectrum disorder produced language samples that were more lexically diverse and intelligible, and that included less topic perseveration compared to boys with fragile X syndrome + autism spectrum disorder. With regards to sampling context, boys in both groups were more talkative and produced longer and more intelligible utterances in their conversation sample compared to their Autism Diagnostic Observation Schedule sample. However, boys with autism spectrum disorder and fragile X syndrome + autism spectrum disorder used a higher proportion of topic perseveration during the conversation sample. Conclusions: Overall, we found similarities as well as distinctions in the expressive language profiles of boys with fragile X syndrome + autism spectrum disorder and boys with idiopathic autism spectrum disorder. Moreover, the Autism Diagnostic Observation Schedule sample elicited a relatively different language profile than the conversation sample for boys in both groups. Implications: These findings help to further elucidate the unique language phenotypes of boys with idiopathic autism spectrum disorder and boys with fragile X syndrome + autism spectrum disorder. Moreover, our findings indicate that multiple language samples may be needed to obtain a comprehensive account of a child's expressive language ability.

RESUMEN

A small randomized group design (N = 20) was used to examine a parent-implemented intervention designed to improve the spoken language skills of school-aged and adolescent boys with FXS, the leading cause of inherited intellectual disability. The intervention was implemented by speech-language pathologists who used distance video-teleconferencing to deliver the intervention. The intervention taught mothers to use a set of language facilitation strategies while interacting with their children in the context of shared story-telling. Treatment group mothers significantly improved their use of the targeted intervention strategies. Children in the treatment group increased the duration of engagement in the shared story-telling activity as well as use of utterances that maintained the topic of the story. Children also showed increases in lexical diversity, but not in grammatical complexity.

RESUMEN

BACKGROUND: In addition to significant cognitive delays, boys with fragile X syndrome display phenotypic characteristics that include delays in language, inattention, social anxiety, and escape-maintained challenging behaviors. Despite these challenges, families affected by fragile X syndrome often have limited access to center-based intervention programs. METHODS: The present study utilized a multiple baseline design across participants to examine the preliminary effectiveness of a 12-week, parent-implemented spoken language intervention for three 5- to 7-year-old boys with fragile X syndrome. The goal of the intervention was to teach the biological mothers of each boy to use a set of verbally responsive language support strategies while participating in shared book reading activities with her child. All aspects of the intervention, including pre- and post-treatment measures, were delivered into the family's home via distance video teleconferencing. RESULTS: Results from this study provide preliminary support for the efficacy of this parent-implemented language intervention approach by demonstrating generalized improvements in both targeted maternal strategy use and measures of child spoken language. CONCLUSIONS: The present study expands upon prior language intervention research utilizing distance delivery of services for families affected by fragile X syndrome. Additionally, the study provides early support for the feasibility of collecting pre- and post-treatment assessments at a distance.

RESUMEN

UNLABELLED: The purpose of this research was to begin to characterize and compare the school and home language environments of 10 preschool-aged children with Autism Spectrum Disorders (ASD). Naturalistic language samples were collected from each child, utilizing Language ENvironment Analysis (LENA) digital voice recorder technology, at 3-month intervals over the course of one year. LENA software was used to identify 15-min segments of each sample that represented the highest number of adult words used during interactions with each child for all school and home language samples. Selected segments were transcribed and analyzed using Systematic Analysis of Language Transcripts (SALT). LENA data was utilized to evaluate quantitative characteristics of the school and home language environments and SALT data was utilized to evaluate quantitative and qualitative characteristics of language environment. Results revealed many similarities in home and school language environments including the degree of semantic richness, and complexity of adult language, types of utterances, and pragmatic functions of utterances used by adults during interactions with child participants. Study implications and recommendations for future research are discussed. LEARNING OUTCOMES: The reader will be able to, (1) describe how two language sampling technologies can be utilized together to collect and analyze language samples, (2) describe characteristics of the school and home language environments of young children with ASD, and (3) identify environmental factors that may lead to more positive expressive language outcomes of young children with ASD.
