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

Public ISBD [article]  inDevelopment and Psychopathology > 25-2 (May 2013) . - p.545-553 Titre : Multiple-object tracking among individuals with Down syndrome and typically developing children Type de document : Texte imprimé et/ou numérique Auteurs : Darlene A. BRODEUR, Auteur ; Lana M. TRICK, Auteur ; Heidi FLORES, Auteur ; Caitlin MARR, Auteur ; Jacob A. 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.

A Point of Departure in the Comparison of Social and Nonsocial Visual Orienting Among Persons With Autism Spectrum Disorders / Tara FLANAGAN in Autism Research, 8-5 (October 2015)

BURACK, Auteur Article en page(s) : p.575-582 Langues : Anglais (eng) Mots-clés : autism spectrum disorders  visual orienting  social orienting  Posner task Index. décimale : PER Périodiques Résumé : Endogenous visual orienting among children with autism spectrum disorders (ASDs) and among typically developing (TD) children was examined using a Posner-type task that was modified to include social and nonsocial cues and targets to test hypotheses regarding information (social or nonsocial) and cue processing (long or short stimulus onset asynchronies (SOAs)). The findings suggest intact endogenous orienting to face and mixed face targets using hand and arrow cues among children with ASDs who were matched to typically developing children (TDC) on the basis of nonverbal mental age (MA) at approximately 8.5 years. The findings from this study challenge the notions of a social orienting impairment and of mechanical social orienting as the children with ASDs in this study demonstrated strong orienting effects in all conditions and social sensitivity in the long stimulus onset asynchrony (SOA) condition.

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.

Utilitarian Attention by Children with Autism Spectrum Disorder on a Filtering Task / Darlene A. BRODEUR in Journal of Autism and Developmental Disorders, 48-12 (December 2018)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 48-12 (December 2018) . - p.4019-4027 Titre : Utilitarian Attention by Children with Autism Spectrum Disorder on a Filtering Task Type de document : Texte imprimé et/ou numérique Auteurs : Darlene A. BRODEUR, Auteur ; J. STEWART, Auteur ; T. DAWKINS, Auteur ; Jacob A. BURACK, Auteur Article en page(s) : p.4019-4027 Langues : Anglais (eng) Mots-clés : Attention  Autism spectrum disorder  Flanker paradigm  Visual filtering Index. décimale : PER Périodiques Résumé : The findings are evidence that persons with ASD benefit more than typically developing (TD) persons from spatial framing cues in focusing their attention on a visual target. Participants were administered a forced-choice task to assess visual filtering. A target stimulus was presented on a screen and flanker stimuli were presented simultaneously with or after the target, with varying stimuli onset asynchronies (SOAs). Regardless of SOA, TD children showed the expected distracting effects with slower reaction times (RTs) when flankers were at closer distances from the target. However, children with ASD displayed shorter RTs in the conditions in which the stimuli were presented simultaneously or with a short SOA. These findings are interpreted as reflecting utilitarian attention among children with ASD.
