Background: This study examined predictive relationships between two indices of language--receptive vocabulary and morphological comprehension--and inhibition in children with specific language impairment (SLI) and typically developing (TD) children. Methods: Participants included 30 children with SLI and 41 TD age-matched peers (8-12 years). At…

Purpose: This article reviews research on executive function (EF) skills in children with autism spectrum disorder (ASD) and the relation between EF and language abilities. The current study assessed EF using nonverbal tasks of inhibition, shifting, and updating of working memory (WM) in school-age children with ASD. It also evaluated the…

This study investigated whether the ability to learn word-object associations following minimal exposure (i.e., fast mapping) was associated with concurrent and later language abilities in children with ASD. Children who were poor learners at age 3½ had significantly lower receptive language abilities than children who successfully learned the new…

Children with autism spectrum disorder (ASD) and specific language impairment (SLI) often have immature lexical-semantic knowledge; however, the organization of lexical-semantic knowledge is poorly understood. This study examined lexical processing in school-age children with ASD, SLI, and typical development, who were matched on receptive…

Relatively little is known about trajectories of autism severity using calibrated severity scores (CSS) from the Autism Diagnostic Observation Schedule, but characterizing these trajectories has important theoretical and clinical implications. This study examined CSS trajectories during early childhood. Participants were 129 children with autism…

Purpose: The authors examined longitudinal associations between 2 categories of parent verbal responsiveness and language comprehension and production 1 year later in 40 toddlers and preschoolers with a diagnosis of an autism spectrum disorder (ASD). Method: Parent-child play samples using a standard toy set were digitally captured and coded for…

Investigation of the impact of speaking rate variations in the linguistic input provided to 32 school-age children (half with specific language impairment (SLI) found both SLI and typical children had similar recognition accuracy, but SLI children had significantly more difficulty with the production of novel words presented at a fast rate.…
