Multiple-object tracking among individuals with Down syndrome and typically developing children / Darlene A. BRODEUR in Development and Psychopathology, 25-2 (May 2013)

BURACK, Auteur Article en page(s) : p.545-553 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We investigated differences in multiple-object tracking among individuals with Down syndrome (DS) as compared to typically developing children matched on a visual–spatial mental age of approximately 5.5 years. In order to ensure that these effects did not originate in differences in encoding or reporting the positions of targets in distracters after a delay, immediate and delayed report were measured for static items. Although their immediate and delayed report for multiple static items was comparable to that of the typically developing children, the participants with DS performed as if they were only capable of tracking a single item at a time regardless of the number of targets that needed to be tracked. This finding is surprising because the operations used in multiple-object tracking are thought to be necessary for visuospatial tasks, which are an area of relative strength among persons with DS. These results call into question the idea that abilities or deficits in multiple-object tracking predict visuospatial performance, and highlight ways that atypical development can inform our understanding of typical development.

Time Estimation Among Low-Functioning Individuals With Autism Spectrum Disorders: Evidence of Poor Sensitivity to Variability of Short Durations / Darlene A. BRODEUR in Autism Research, 7-2 (April 2014)  

Public ISBD [article]  inAutism Research > 7-2 (April 2014) . - p.237-244 Titre : Time Estimation Among Low-Functioning Individuals With Autism Spectrum Disorders: Evidence of Poor Sensitivity to Variability of Short Durations Type de document : Texte imprimé et/ou numérique Auteurs : Darlene A. BRODEUR, Auteur ; Cathryn GORDON-GREEN, Auteur ; Heidi FLORES, Auteur ; Jacob A. BURACK, Auteur Article en page(s) : p.237-244 Mots-clés : time  perception  autism spectrum disorder  low-functioning Index. décimale : PER Périodiques Résumé : Time estimation of short durations (under 1?sec) was examined in low-functioning individuals with autism spectrum disorder (ASD) and typically developing (TD) children matched on mental age. Temporal bisection and generalization tasks were used to examine basic perceptual timing mechanisms. For both tasks, the participants with ASD demonstrated less sensitivity to variability in short durations than the TD children, adding to a growing body of literature suggesting deficits in timing exist for longer durations. The results highlight the need to examine multiple levels of processing of time-related information from basic perceptual mechanisms to higher level cognitive mechanisms.
