RESUMEN

PURPOSE: Expressive language impairments are common among school-age boys with fragile X syndrome (FXS) and autistic boys. Given the high co-occurrence of autism spectrum disorder (ASD) among individuals with FXS, cross-condition comparisons can elucidate the specificity of such impairments as they relate to ASD. Language samples can provide fruitful information regarding individuals' grammatical skills in less structured formats relative to standardized measures. This study examined grammatical errors produced during a conversational language sample among 20 boys with FXS and co-occurring ASD (FXS + ASD) and 19 autistic boys matched on ASD severity. METHOD: Language samples were coded for omissions and errors at the word and utterance levels. Participants' grammatical errors were also compared to separate mental age-matched and mean length of utterance-matched boys from a reference database. RESULTS: Boys with FXS + ASD and autistic boys produced similar rates of errors across all categories. Relative to their matched comparison groups, boys with FXS + ASD and autistic boys produced significantly more omissions during conversation. CONCLUSIONS: These findings suggest that omissions may be a unique grammatical marker associated with the ASD phenotype. Further examination of omissions across diagnostic groups would aid in clarifying the specificity of omissions in the language phenotype of ASD.

RESUMEN

Objective: College students with autism spectrum disorder (ASD) experience elevated drop-out rates, peer difficulties, and mental health concerns compared to their neurotypical counterparts. Thus, the firsthand concerns of college students with ASD were examined, so that supports can be appropriately tailored. Methods: Responses of 31 college students with ASD were examined in relation to 39 demographically similar neurotypical students regarding students' college experiences (e.g., social interactions, mental health, daily living habits). Students with ASD also provided recommendations for improving college support programs. Results: Difficulties unique to students with ASD included trouble conversing with peers, feeling isolated despite preferences to be alone, inaccessible extra-curricular activities, and experiencing anxiety and depression resulting from social demands. Notably, these students endorsed desire for a "social group" to learn from the experiences of successful students. Conclusions: Practical targets were identified for university-implemented support groups, such as navigating social interactions and processing experiences with peers.

RESUMEN

Young children with Down syndrome (DS) have language delays beginning early in life. Book reading with parents provides a context for capitalizing on language learning opportunities. This study evaluated the quantity and quality of language input among mothers and fathers of young children with DS during book reading interactions and investigated associations with child language. Findings revealed that mothers were more talkative and used more descriptive language, whereas fathers spent more time reading the book text. Moreover, maternal and paternal input were correlated with different measures of child language, suggesting that mothers and fathers may use divergent approaches to support language development.

RESUMEN

The present research examined recognition of basic (happy, fear, sad) and self-conscious (pride, embarrassment, guilt) emotions from situational contexts in children with Autism Spectrum Disorder (ASD) and neurotypical children (Study 1). Results showed that children with ASD were less accurate in recognizing fear, embarrassment, and guilt situations than neurotypical children. Additionally, the research explored whether recognition of these emotions from situational contexts could be improved in children with ASD after a 4-week computerized emotion intervention (Study 2). Following the intervention, children showed better recognition of embarrassment and guilt, but no improvement in recognizing fear. In children with ASD, significant negative relations were found between ASD symptomatology and recognition of guilt (Study 1), although ASD symptomatology did not impact the intervention's efficacy (Study 2). Additional explanations for these findings are provided.

RESUMEN

Purpose The goal of this study was to characterize and quantify maternal use of decontextualized and contextualized input during mother-child interactions including young children with Down syndrome (DS). Method Participants included 22 mother-child dyads with DS (M age = 42.8 months) and 22 mother-child dyads with typical development (M age = 44.0 months). Parent-child language samples were collected during free-play, book reading, and snack time, and coded for maternal decontextualized (i.e., pretend, explanatory, and narrative talk) and contextualized input (i.e., descriptions, conversation, praise, questions, and directives). Results Mothers of children with DS used a larger proportion of pretend talk compared to other types of decontextualized input and also used a larger proportion of questions, conversation, and descriptions compared to other types of contextualized language. Mothers of children with DS generally used a smaller proportion of decontextualized input compared to mothers of children with typical development, with the exception of pretend talk. Maternal decontextualized input was not related to children's age or language ability in DS. Conclusions Findings shed new light on the early language environments of children with DS, providing important insight into the ways that mothers of children with DS are incorporating decontextualized and contextualized talk into early mother-child conversations. Additional implications and future directions are discussed.

RESUMEN

BACKGROUND: Research has demonstrated that writing may be challenging for many children with Autism Spectrum Disorder (ASD; Mayes & Calhoun, 2006). In our study, we used linguistic analysis to identify and examine the personal narrative writing skills of children with ASD in comparison to neurotypical (NT) children. METHOD: This study included 22 children with ASD and 22 NT children. Groups did not differ in terms of age, IQ, and language. Writing samples were coded and compared for aspects of microstructure (e.g., lexical and syntactic complexity, errors) and macrostructure (e.g., quality, or ratings of coherence, structure, and content). We also examined the link between theory of mind (ToM) and personal narrative writing. Of interest was whether ToM uniquely predicted writing performance after controlling for diagnostic group, chronological age, and language ability. RESULTS: The texts of children with ASD were less syntactically diverse, contained more grammatical errors, and were reduced in overall quality compared to NT children. However, children with ASD did not differ from NT children in terms of lexical complexity, frequency of writing conventions errors, and use of evaluative devices. Overall, ToM uniquely predicted syntactic complexity and text quality in children. CONCLUSIONS: Study findings showed that children with ASD demonstrate some challenges with personal narrative writing compared to NT children. Additionally, difficulty with narrative writing was linked to poorer ToM performance, particularly in children with ASD. Findings highlight the utility of obtaining a variety of writing outcomes, as well as mechanisms related to writing, when evaluating writing for educational decisions.

RESUMEN

Purpose Question-asking serves as a tool to learn new information and is important in both academic and social settings. Boys with idiopathic autism spectrum disorder (ASD) and boys with fragile X syndrome and comorbid ASD (FXS + ASD) have similar social communication deficits, which may have downstream effects on their question-asking ability. This study examined question-asking in school-age boys with idiopathic ASD and FXS + ASD, including the role of ASD severity, expressive grammatical complexity (measured by mean length of utterance [MLU]), and IQ. Method Twenty-five boys with FXS + ASD and 21 boys with idiopathic ASD (ages 9-16 years) were included in this study. Autism Diagnostic Observation Schedule assessments were transcribed and coded for the frequency, function, and appropriateness of spontaneous questions asked. We examined group differences in these aspects of question-asking and relationships between question-asking and ASD severity, MLU, and IQ within each group. Results Boys with FXS + ASD asked more questions than boys with idiopathic ASD, although boys with idiopathic ASD asked a higher proportion of appropriate questions. Boys with idiopathic ASD also asked the examiner more personal questions than the boys with FXS + ASD. ASD severity and MLU were related to the proportion of clarification questions in FXS + ASD, and ASD severity was also related to the proportion of personal questions in this group. For the boys with idiopathic ASD, ASD severity was related to the total number of questions asked. Conclusions Our findings highlight similarities and differences between boys with FXS + ASD and idiopathic ASD in their spontaneous question production and indicate that ASD severity and grammatical language are differentially important for question-asking. This study has implications for targeted treatment in question-asking skills for boys with FXS + ASD and ASD.

RESUMEN

Purpose This study compared and characterized the tense and agreement productivity of boys with fragile X syndrome (FXS), children with developmental language disorder (DLD), and children with typical development (TD) matched on mean length of utterance. Method Twenty-two boys with FXS (M age = 12.22 years), 19 children with DLD (M age = 4.81 years), and 20 children with TD (M age = 3.23 years) produced language samples that were coded for their productive use of five tense markers (i.e., third-person singular, past tense -ed, copula BE, auxiliary BE, and auxiliary DO) using the tense and agreement productivity score. Children also completed norm-referenced cognitive and linguistic assessments. Results Children with DLD generally used tense and agreement markers less productively than children with TD, particularly third-person singular and auxiliary BE. However, boys with FXS demonstrated a more complicated pattern of productivity, where they were similar to children with DLD and TD, depending on the tense marker examined. Results revealed that children with DLD and TD showed a specific developmental sequence of the individual tense markers that aligns with patterns documented by previous studies, whereas boys with FXS demonstrated a more even profile of productivity. Conclusions These findings help to further clarify areas of overlap and discrepancy in tense and agreement productivity among boys with FXS and children with DLD. Additional clinical implications of these results are discussed.

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

Using detailed linguistic analysis, this study examined the expository writing abilities of school-age children with autism spectrum disorder (ASD) in comparison to neurotypical (NT) children. Associations between executive functioning (EF) and writing ability in children with and without ASD were also explored. Compared to NT peers, children with ASD wrote shorter expository texts that contained more grammatical errors, and needed more assistance from the experimenter to complete the writing assessment. However, the texts of children with and without ASD did not differ in their lexical diversity, use of writing conventions, and overall quality. Analyses also revealed that greater EF was associated with better writing outcomes in both groups. Educational implications of these findings are discussed.

RESUMEN

In this study, monolingual (English) and bilingual (English/Spanish, English/Urdu) five- and six-year-old children completed a grammaticality judgment test in order to assess their awareness of the grammaticality of two types of syntactic constructions in English: word order and gender representation. All children were better at detecting grammatically correct and incorrect word order constructions than gender constructions, regardless of language group. In fact, bilingualism per se did not impact the results as much as receptive vocabulary range. For example, children with the highest receptive vocabulary scores were more accurate in detecting incorrect word order constructions (i.e., word order violations, semantic anomalies) and incorrect gender agreement than children in the lower receptive vocabulary ranges. However, no differences were found between the ranges for ambiguous gender constructions. These results highlight the importance of receptive vocabulary ability on syntactic awareness performance, regardless of language group.

RESUMEN

Self-conscious emotions (e.g., guilt, shame, and pride) are complex emotions that require self-reflection and self-evaluation, and are thought to facilitate the maintenance of societal norms and personal standards. Despite the importance of self-conscious emotions, most research has focused on basic emotion processing in children with Autism Spectrum Disorders (ASD). Therefore, in the present study, we used the Test of Self-Conscious Affect for Children (TOSCA-C) to assess proneness to, or propensity to experience, the self-conscious emotions guilt, shame, and pride in children with ASD and neurotypical children. The TOSCA-C is designed to capture a child's natural tendency to experience a given emotion across a range of everyday situations [Tangney, Stuewig, & Mashek, 2007]. We also assessed how individual characteristics contribute to the development of proneness to self-conscious emotions, including theory of mind (ToM) and ASD symptomatology. In comparison to neurotypical children, children with ASD showed less proneness to guilt, although all children showed relatively high levels of proneness to guilt. Greater ToM ability was related to more proneness to guilt and authentic pride in children with ASD. Additionally, we found that children with ASD with more severe symptomatology were more prone to hubristic pride. Our results provide evidence of differences in proneness to self-conscious emotions in children with ASD, as well as highlight important mechanisms contributing to how children with ASD may experience self-conscious emotions. Autism Res 2018,11:883-892. ©2017 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: This research examined proneness to guilt, shame, and pride in children with Autism Spectrum Disorders (ASD) and neurotypical children. We found that children with ASD showed less proneness to guilt than neurotypical children. Better understanding of theory of mind was related to greater proneness to guilt and pride, but only for children with ASD. These findings are important because these complex emotions are linked with both positive and negative social behaviors towards others and oneself.

RESUMEN

Self-conscious emotions, such as shame, guilt and pride, facilitate our social interactions by motivating us to adhere to social norms and external standards. In this study, we examined proneness to shame, guilt, hubristic pride and authentic pride in adults with Autism Spectrum Disorder traits (ASD-T) and in neurotypical (NT) adults. Relations between proneness to self-conscious emotions and theory of mind (ToM), fear of negative evaluation, and social functioning were also assessed. Adults with ASD-T showed greater proneness to shame, and less proneness to guilt and pride than NT adults. Both ToM and fear of negative evaluation predicted proneness to self-conscious emotions in ASD-T. These findings are discussed in terms of understanding complex emotion processing in adults with ASD-T.
