The Role of Language in the Social and Academic Functioning of Children With ADHD.

OBJECTIVE: To provide an in-depth examination of whether pragmatic, expressive, receptive, and narrative language are associated with the social and academic functioning of children with ADHD. METHOD: Children with ADHD (n = 46) and neurotypical comparison (NC) children (n = 40) aged 7 to 11 years completed tasks measuring expressive, receptive, and narrative language, while parents rated pragmatic language and social- and academic functioning. RESULTS: Children with ADHD differed significantly from NC children on pragmatic language, expressive language, receptive language, and narrative coherence. An examination of indirect effects revealed that a significant proportion of the association between ADHD and social functioning was shared with pragmatic language, while a significant proportion of the association between ADHD and academic difficulties was shared with pragmatic language as well as with expressive language. CONCLUSION: This preliminary study supports the clinical relevance of language in relation to the academic- and social functioning of children with ADHD.

Metaphor Comprehension in Individuals with Autism Spectrum Disorder: Core Language Skills Matter.

Poor metaphor comprehension was considered a hallmark of autism spectrum disorder (ASD), but recent research has questioned the extent and the sources of these difficulties. In this cross-sectional study, we compared metaphor comprehension in individuals with ASD (N = 29) and individuals with typical development (TD; N = 31), and investigated the relationship between core language and metaphor comprehension. Individuals with ASD showed more difficulty but also a more variable performance in both metaphor and literal items of the task used than individuals with TD did. This indicates that core language ability accounts for metaphor comprehension and should be considered in future research and interventions aiming to improve metaphor comprehension in individuals with ASD.

Syntax and Morphology in Danish-Speaking Children with Autism Spectrum Disorder.

The current study examined delays in syntax and morphology, and vocabulary, in autism spectrum disorder (ASD). Children ages 4-6 years with ASD (n = 21) and typical development (n = 21), matched on nonverbal mental age, completed five language tasks. The ASD group had significant delays in both syntax and morphology, and vocabulary measures, with significant within-group heterogeneity; furthermore, syntactic and morphological measures were impaired even for subgroups matched on vocabulary. Children in the ASD group without early language delay showed syntactic and morphological impairment, with intact performance on vocabulary and sentence repetition. Findings indicate that syntactic and morphological impairments are a significant concern for high-functioning children with ASD, and may be overlooked if language evaluation focuses exclusively on vocabulary.
