The Complex Information Processing Theory proposes this pattern reflects an altered capacity to respond to cognitive demands. This study compared how complexity induced by time constraints on processing affect cognitive function in individuals with ASD and typically-developing individuals. On a visual information-processing task, the Subtle Cognitive Impairment Test, both groups exhibited sensitivity to time-constraints. Further, 65 % of individuals with ASD demonstrated deficits in processing efficiency, possibly attributable to the effects of age and clinical comorbidities, like attention deficit hyperactivity disorder. These findings suggest that for some ASD individuals there are significant impairments in processing efficiency, which may have implications for education and interventions.

Lexical processing in individuals with high-functioning autism and Asperger’s disorder / Samantha SPEIRS in Autism, 15-3 (May 2011)  

Public ISBD [article]  inAutism > 15-3 (May 2011) . - p.307-325 Titre : Lexical processing in individuals with high-functioning autism and Asperger’s disorder Type de document : texte imprimé Auteurs : Samantha SPEIRS, Auteur ; Greg YELLAND, Auteur ; Nicole J. RINEHART, Auteur ; Bruce J. TONGE, Auteur Année de publication : 2011 Article en page(s) : p.307-325 Langues : Anglais (eng) Mots-clés : Asperger’s disorder  autism  language  lexical processing  masked priming  word recognition Index. décimale : PER Périodiques Résumé : The presence or absence of clinically delayed language development prior to 3 years of age is a key, but contentious, clinical feature distinguishing autism from Asperger’s disorder. The aim of this study was to examine language processing in children with high-functioning autism (HFA) and Asperger’s disorder (AD) using a task which taps lexical processing, a core language ability. Eleven individuals with HFA, 11 with AD and 11 typically developing (TD) individuals completed a masked priming task, a psycholinguistic paradigm that directly examines lexical processes. Within-group analyses revealed the AD and TD groups had intact lexical processing systems and orthographic processing of the written word. The outcomes for the HFA group were ambiguous, suggesting that their lexical processing system is either delayed or is structurally different. This suggests that fundamental differences in lexical processing exist between HFA and AD and remain evident later in development.
