Atypical Interference of Local Detail on Global Processing in High-functioning Autism and Asperger's Disorder / Nicole J. RINEHART in Journal of Child Psychology and Psychiatry, 41-6 (September 2000)

Participants observed a large or “global” number composed of smaller or “local” numbers. The response was contingent upon the identification of either the large stimulus or the small stimuli. Relative to age, sex, and IQ matched controls, global processing in children and adolescents with autism (N= 12) and Asperger's disorder (N= 12) was more vulnerable when the local stimuli were incongruent. The autism group made more global errors than their matched control group, regardless of whether there was local incongruence. In contrast, the Asperger's disorder group made a similar number of global errors as their respective control group. These results were discussed in relation to an “absence of global precedence” notion, “weak central coherence” theory, and right-hemisphere dysfunction. The neurobiological significance of these findings were discussed in the context of a fronto-striatal model of dysfunction.

Brief report: Inhibition of return in young people with autism and Asperger's disorder / Nicole J. RINEHART in Autism, 12-3 (May 2008)  

Public ISBD [article]  inAutism > 12-3 (May 2008) . - p.249-260 Titre : Brief report: Inhibition of return in young people with autism and Asperger's disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nicole J. RINEHART, Auteur ; John L. BRADSHAW, Auteur ; Simon A. MOSS, Auteur ; Avril V. BRERETON, Auteur Année de publication : 2008 Article en page(s) : p.249-260 Langues : Anglais (eng) Mots-clés : Asperger's-disorder autism inhibition-of-return visual-search Index. décimale : PER Périodiques Résumé : The aim of this study was to investigate whether the superior search abilities observed in autism/Asperger's disorder may in part be a consequence of a more pronounced inhibition of return (IOR). Contrary to our prediction, IOR in individuals with autism was comparable to the matched comparison group. However, the autism group committed more false alarm responses than the matched comparison group; this may reflect a possible inhibitory deficit, or suggest that individuals with autism rely more on probabilities to determine their behavioural responses. There was a borderline-significant trend (p = 0.052) to indicate that IOR may be more pronounced in individuals with Asperger's disorder. In contrast to the autism group, the Asperger's disorder group had a pattern of false alarm responses similar to that of the comparison group. The findings further inform Minshew's complex information processing theory which seeks to establish which areas of neuropsychological functioning are preserved and deficit in autism.

A Deficit in Shifting Attention Present in High-Functioning Autism but not Asperger’s Disorder / Nicole J. RINEHART in Autism, 5-1 (March 2001)  

Public ISBD [article]  inAutism > 5-1 (March 2001) . - p.67-80 Titre : A Deficit in Shifting Attention Present in High-Functioning Autism but not Asperger’s Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nicole J. RINEHART, Auteur ; John L. BRADSHAW, Auteur ; Simon A. MOSS, Auteur ; Avril V. BRERETON, Auteur ; Bruce J. TONGE, Auteur Article en page(s) : p.67-80 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The aim of this study was to examine executive functioning, in particular, attentional set-shifting deficits in high-functioning autism (n = 12) and Asperger’s disorder (n = 12). A large or global digit composed of smaller or local digits was presented during each trial. The participants indicated the presence of 1s or 2s by pressing the appropriate button. These targets could appear globally or locally. Relative to IQ, sex and age matched controls, reaction time to global targets in individuals with autism was retarded when the previous target appeared locally. This deficiency in shifting from local to global processing, however, was not observed in individuals with Asperger’s disorder. The theoretical and neurobiological significance of this dissociation in executive functioning in these clinically related disorders was explored.
