Purpose: Infants with autism spectrum disorder (ASD) produce fewer play actions and gestures than neurotypical infants (e.g., Mastrogiuseppe et al., 2015; Veness et al., 2012; Zwaigenbaum et al., 2005). The purpose of this study was to investigate whether different "types" of actions and gestures are more or less likely to develop…

Iarocci, Grace; Hutchison, Sarah M.; O'Toole, Gillian – Journal of Autism and Developmental Disorders, 2017
Parents and professionals are concerned that second language exposure may delay communication in children with ASD. In this study 174 youth (6-16 years) with and without ASD, exposed to a second language, were compared on executive function (EF) and functional communication (FC) with their peers without exposure. There were no significant…

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…

Hagberg, Bibbi S.; Miniscalco, Carmela; Gillberg, Christopher – Research in Developmental Disabilities: A Multidisciplinary Journal, 2010
Many studies have shown that children with autism spectrum disorders (ASD) and attention-deficit/hyperactivity disorder (ADHD) have had early indicators of language delay. The aim of the present study was to examine the cognitive profile of school age children referred to a specialist clinic for ASD, ADHD, or both, and relate this profile…
