Processing Speed is Impaired in Adults with Autism Spectrum Disorder, and Relates to Social Communication Abilities / Sarah M. HAIGH in Journal of Autism and Developmental Disorders, 48-8 (August 2018)
[article]
Titre : Processing Speed is Impaired in Adults with Autism Spectrum Disorder, and Relates to Social Communication Abilities Type de document : Texte imprimé et/ou numérique Auteurs : Sarah M. HAIGH, Auteur ; Jennifer A. WALSH, Auteur ; C. A. MAZEFSKY, Auteur ; N. J. MINSHEW, Auteur ; S. M. EACK, Auteur Article en page(s) : p.2653-2662 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Information processing Matrics Speed of processing Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is characterized by a variety of social and non-social behavioral deficits. One potential mechanism that could unify this diverse profile of behaviors is slower processing speed. Seventy-six high-functioning adults with ASD were compared to 64 matched controls on standardized measures of processing speed. Participants with ASD were significantly slower on all measures, and on the composite score from the three tests (d's > .65). ASD participants with slower processing speeds scored higher on the ADOS Communication and Reciprocal Social Interaction scale (r = .34). These findings provide evidence of slower processing speeds in adults with ASD, and that this may be contributing to impairments in social communication skills. Interventions that improve processing speed might improve social communication abilities in ASD.

YELLAND, Auteur Article en page(s) : p.2809-2819 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Cognitive processing Processing efficacy Subtle Cognitive Impairment Test Speed of processing Index. décimale : PER Périodiques Résumé : Autism spectrum disorders (ASD) are characterised by a unique pattern of preserved abilities and deficits within and across cognitive domains. 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.

Previous research has examined these capabilities in typically developing (TD) children and individuals with intellectual disabilities (ID); however, there is limited research on these abilities in children with Autism Spectrum Disorders (ASD). Twenty-one TD and eighteen ASD children were presented with circular visual arrays of letters for 100 ms and were asked to recall as many letters as possible or a single letter that was cued for recall. Groups did not differ in the number of items recalled, the rate of information decay, or speed of information processing. These findings suggest that iconic memory is an intact skill for children with ASD, a result that has implications for subsequent information processing.

Titre : The Role of Timing in Testing Nonverbal IQ in Children with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Margaret MCGONIGLE-CHALMERS, Auteur ; Meabh MCSWEENEY, Auteur Année de publication : 2013 Article en page(s) : p.80-90 Langues : Anglais (eng) Mots-clés : Children with ASD Nonverbal intelligence testing Speed of processing WISC-III Index. décimale : PER Périodiques Résumé : 15 School-aged high functioning children on the autistic spectrum were compared with a neurotypical cohort on the WISC-III and the KABC-II, to determine the impact of the relatively more strict timing criteria of the former test on the evaluation of nonverbal intelligence. Significant group effects, showing lower performance by the ASD group were found for three of the five sub-tests for the WISC but not for the KABC, peaks and troughs were more evident for the WISC, and the evaluation of intellectual level was also markedly lower for ASD children on the WISC-III as opposed to the KABC-II. The results are discussed in terms of how speed of processing can impact on how children with ASD are 'matched' against neurotypical samples.

MINSHEW, Auteur Article en page(s) : p.794-806 Langues : Anglais (eng) Mots-clés : Autism Attentional shifting Speed of processing Perceptual development Index. décimale : PER Périodiques Résumé : This study used the modality shift experiment, a relatively simple reaction time measure to visual and auditory stimuli, to examine attentional shifting within and across modalities in 33 children and 42 adults with high-functioning autism as compared to matched numbers of age- and ability-matched typical controls. An exaggerated “modality shift effect” relative to the TD children occurred for the children with autism in conditions involving the reaction time when shifting from sound to light but not from light to sound. No exaggerated MSE was found for the adults with autism; rather, their responses were characterized by a generalized slowness relative to the adults with TD. These results suggest a lag in maturational development in autism in basic information processing mechanisms.
