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)
[article]
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.

E. STEWART in Journal of Autism and Developmental Disorders, 48-4 (April 2018)
[article]
Titre : Autistic Traits and Enhanced Perceptual Representation of Pitch and Time Type de document : Texte imprimé et/ou numérique Auteurs : M. E. STEWART, Auteur ; T. D. GRIFFITHS, Auteur ; M. GRUBE, Auteur Article en page(s) : p.1350-1358 Langues : Anglais (eng) Mots-clés : Audition Autism-Spectrum Quotient Enhanced representation Loudness Pitch Sensory processing Time Index. décimale : PER Périodiques Résumé : Enhanced basic perceptual discrimination has been reported for pitch in individuals with autism spectrum conditions. We test whether there is a correlational pattern of enhancement across the broader autism phenotype and whether this correlation occurs for the discrimination of pitch, time and loudness. Scores on the Autism-Spectrum Quotient correlated significantly with the pitch discrimination (r = -0.51, p < 0.05) and the time-interval discrimination (r = -0.45, p < 0.05) task that were based on a fixed reference. No correlation was found for intensity discrimination based on a fixed reference, nor for a variable reference based time-interval discrimination. The correlations suggest a relationship between autistic traits and the ability to form an enhanced, stable and highly accurate representation of auditory events in the pitch and time dimensions.

Titre : Mathematics performance, response time, and enjoyment of eighth-grade autistic students and their general education peers Type de document : Texte imprimé et/ou numérique Auteurs : Xin WEI, Auteur ; Susu ZHANG, Auteur ; Jihong ZHANG, Auteur ; Jennifer YU, Auteur Article en page(s) : p.2518-2529 Mots-clés : autism enjoyment interest math performance persistence time visuospatial skills word problems Index. décimale : PER Périodiques Résumé : For autistic students receiving special education services, little is known about their relative strengths, weaknesses, and enjoyment across different math content areas; their overall math interest and persistence are also not well-studied. Using the 2017 eighth-grade National Assessment of Education Progress data, this study finds, relative to general education peers with the same math proficiency level, autistic students scored higher and exhibited faster speed in solving visuospatial problems (e.g. identifying figures), but scored lower on math word problems with complex language or social context. Autistic students reported a higher level of enjoyment in solving math problems related to finding areas of shapes or figures but a lower level of persistence than their non-autistic, general education peers. Our work points out the need to help autistic students overcome their weaknesses in word problems and develop their mathematical persistence.
