Charbonneau, Geneviève; Bertone, Armando; Véronneau, Marie; Girard, Simon; Pelland, Maxime; Mottron, Laurent; Lepore, Franco; Collignon, Olivier – Journal of Autism and Developmental Disorders, 2020
Although impairment in sensory integration is suggested in the autism spectrum (AS), empirical evidences remain equivocal. We assessed the integration of low-level visual and tactile information within and across modalities in AS and typically developing (TD) individuals. TD individuals demonstrated increased redundancy gain for cross-modal…

Alary, Flamine; Duquette, Marco; Goldstein, Rachel; Chapman, C. Elaine; Voss, Patrice; La Buissonniere-Ariza, Valerie; Lepore, Franco – Neuropsychologia, 2009
Previous studies have shown that blind subjects may outperform the sighted on certain tactile discrimination tasks. We recently showed that blind subjects outperformed the sighted in a haptic 2D-angle discrimination task. The purpose of this study was to compare the performance of the same blind (n = 16) and sighted (n = 17, G1) subjects in three…

Early Visual Deprivation Alters Multisensory Processing in Peripersonal Space
Peer reviewed Peer reviewed

Collignon, Olivier; Charbonneau, Genevieve; Lassonde, Maryse; Lepore, Franco – Neuropsychologia, 2009
Multisensory peripersonal space develops in a maturational process that is thought to be influenced by early sensory experience. We investigated the role of vision in the effective development of audiotactile interactions in peripersonal space. Early blind (EB), late blind (LB) and sighted control (SC) participants were asked to lateralize…
