Language abilities in adolescents with autism spectrum disorders (ASDs) are variable and can be challenging to ascertain with confidence. This study aimed to compare and evaluate different forms of language assessment: standardized language testing, narrative analysis and parent/teacher reports. 14 adolescents with ASD and 14 typically developing…

Purpose: The Preschool Language Scale, Fourth Edition (PLS-4; Zimmerman, Steiner, & Pond, 2002) was used to examine syntactic and semantic language skills in preschool children with autism spectrum disorders (ASD) to determine its suitability for use with this population. We expected that PLS-4 performance would be better in more…

Although pragmatic deficits are well documented in autism, little is known about the extent to which grammatical knowledge in this disorder is deficient, or merely delayed when compared to that of typically developing children functioning at similar linguistic or cognitive levels. This study examines the knowledge of constraints on the…

This study aimed to test the hypothesis that children with autism spectrum disorder (ASD) use their knowledge of complement syntax as a means of "hacking out" solutions to false belief tasks, despite lacking a representational theory of mind (ToM). Participants completed a "memory for complements" task, a measure of receptive vocabulary, and…

Individuals with autism exhibit significant impairments in prosody production, yet there is a paucity of research on prosody comprehension in this population. The current study adapted a psycholinguistic paradigm to examine whether individuals with autism are able to use prosody to resolve syntactically ambiguous sentences. Participants were 21…

Background: Fragile X syndrome (FXS) is the most common known inherited cause of intellectual disability, yet very few studies have explored the language comprehension skills of children with FXS. We examined the receptive vocabulary, grammatical morphology and syntax skills of boys with FXS (who were additionally classified as having autism,…

Six autistic children and seven children with relatively specific language impairment were asked to act out a series of sentences. Both groups made little use of a semantically based probable event strategy but were more likely to use a syntactically based word order strategy, similar to normals matched for receptive language age.
