Background and aims: A substantial minority of autistic individuals score within typical ranges on standard language tests, suggesting that autism does not necessarily affect language acquisition. This idea is reflected in current diagnostic criteria for autism, wherein language impairment is no longer included. However, some work has suggested…

Purpose: The goal of this work was to examine the semantic and syntactic properties of the vocabularies of autistic and non-autistic infants and toddlers to see if children in these two groups know different kinds of words. We focused on both receptive and expressive vocabularies. For expressive vocabulary, we looked only at the "active"…

Despite emerging awareness of gender diversity in the autistic population, our understanding of autism remains limited to cisgender boys and men. We conducted a scoping review to better understand how structural language skills (i.e. syntax, semantics, narrative) differ across sex/gender within autism, and how gender diversity is incorporated in…

Children with autism spectrum disorder often have significant language delays. But do they learn language differently than neurotypical toddlers? We compared the lexical skills of 64 preverbal and minimally verbal children with autism spectrum disorder to 461 vocabulary-size-matched typically developing toddlers. We also examined social features…

Purpose: Several studies have reported that "useful speech" at 5 years of age predicts outcomes in individuals with autism spectrum disorder (ASD), but this skill has been vaguely defined. This study investigates which specific aspects of expressive language in children with ASD best predict adult language and communication outcomes.…

Sex differences in autism may in part be understood by an atypical sex profile of executive function and non-executive function. In this study, we compared females and males with autism against non-autistic individuals on neuropsychological and self-report measures to examine whether any sex differences in executive function and non-executive…

Purpose: Extant research indicates that children and adolescents with autism spectrum disorder (ASD) without an intellectual disability (ID) often experience difficulty comprehending written texts that is unexpected in comparison with their cognitive abilities. This study investigated the development of two key skills, narrative and inference…

Purpose: To investigate sensitivity to prosodic and semantic cues to emotion in individuals with high-functioning autism (HFA). Method: Emotional prosody and semantics were independently manipulated to assess the relative influence of prosody versus semantics on speech processing. A sample of 10-year-old typically developing children (n = 10) and…

This study analyses the case of a gifted child (9;6 year) with autism spectrum disorder (ASD) who had a particularly high verbal IQ (146) and a specific cognitive, linguistic, and metalinguistic profile. A description of some salient behavioral characteristics of the child is provided. A metalinguistic ability test assessing metagrammatical,…

Previous work leaves open the question of whether children with autism spectrum disorders aged 6-12?years have delay in producing gestures compared to their typically developing peers. This study examined gestural production among school-aged children in a naturalistic context and how their gestures are semantically related to the accompanying…
