Guy, Jacalyn; Mottron, Laurent; Berthiaume, Claude; Bertone, Armando – Journal of Autism and Developmental Disorders, 2019
Individuals with autism spectrum disorder (ASD) demonstrate superior performances on visuo-spatial tasks emphasizing local information processing; however, findings from studies involving hierarchical stimuli are inconsistent. Wide age ranges and group means complicate their interpretability. Children and adolescents with and without ASD completed…

Bouvet, Lucie; Mottron, Laurent; Valdois, Sylviane; Donnadieu, Sophie – Journal of Autism and Developmental Disorders, 2016
Auditory stream segregation allows us to organize our sound environment, by focusing on specific information and ignoring what is unimportant. One previous study reported difficulty in stream segregation ability in children with Asperger syndrome. In order to investigate this question further, we used an interleaved melody recognition task with…

Meilleur, Andrée-Anne S.; Jelenic, Patricia; Mottron, Laurent – Journal of Autism and Developmental Disorders, 2015
Outstanding skills, including special isolated skills (SIS) and perceptual peaks (PP) are frequent features of autism. However, their reported prevalence varies between studies and their co-occurrence is unknown. We determined the prevalence of SIS in a large group of 254 autistic individuals and searched for PP in 46 of these autistic individuals…

Massand, Esha; Bowler, Dermot M.; Mottron, Laurent; Hosein, Anthony; Jemel, Boutheina – Journal of Autism and Developmental Disorders, 2013
Recognition memory in autism spectrum disorder (ASD) tends to be undiminished compared to that of typically developing (TD) individuals (Bowler et al. 2007), but it is still unknown whether memory in ASD relies on qualitatively similar or different neurophysiology. We sought to explore the neural activity underlying recognition by employing the…

Sahyoun, Cherif P.; Soulieres, Isabelle; Belliveau, John W.; Mottron, Laurent; Mody, Maria – Journal of Autism and Developmental Disorders, 2009
We investigated linguistic and visuospatial processing during pictorial reasoning in high-functioning autism (HFA), Asperger's syndrome (ASP), and age and IQ-matched typically developing participants (CTRL), using three conditions designed to differentially engage linguistic mediation or visuospatial processing (visuospatial, V; semantic, S;…

Jemel, Boutheina; Mottron, Laurent; Dawson, Michelle – Journal of Autism and Developmental Disorders, 2006
Within the last 10 years, there has been an upsurge of interest in face processing abilities in autism which has generated a proliferation of new empirical demonstrations employing a variety of measuring techniques. Observably atypical social behaviors early in the development of children with autism have led to the contention that autism is a…

Mottron, Laurent; Dawson, Michelle; Soulieres, Isabelle; Hubert, Benedicte; Burack, Jake – Journal of Autism and Developmental Disorders, 2006
We propose an "Enhanced Perceptual Functioning" model encompassing the main differences between autistic and non-autistic social and non-social perceptual processing: locally oriented visual and auditory perception, enhanced low-level discrimination, use of a more posterior network in "complex" visual tasks, enhanced perception…

Gagnon, Louise; Mottron, Laurent; Bherer, Louis; Joanette, Yves – Journal of Autism and Developmental Disorders, 2004
This study examined the hypothesis of superior quantification abilities of persons with high functioning autism (HFA). Fourteen HFA individuals (mean age: 15 years) individually matched with 14 typically developing (TD) participants (gender, chronological age, full-scale IQ) were asked to quantify as accurately and quickly as possible…
