Different Verbal Learning Strategies in Autism Spectrum Disorder: Evidence from the Rey Auditory Verbal Learning Test / Dermot M. BOWLER in Journal of Autism and Developmental Disorders, 39-6 (June 2009)
[article]
Titre : Different Verbal Learning Strategies in Autism Spectrum Disorder: Evidence from the Rey Auditory Verbal Learning Test Type de document : Texte imprimé et/ou numérique Auteurs : Dermot M. BOWLER, Auteur ; Laurent MOTTRON, Auteur ; Elyse LIMOGES, Auteur Année de publication : 2009 Article en page(s) : p.910-915 Langues : Anglais (eng) Mots-clés : High-functioning-ASD Verbal-learning Free-recall Serial-position-effects Memory Index. décimale : PER Périodiques Résumé : The Rey Auditory Verbal Learning Test, which requires the free recall of the same list of 15 unrelated words over 5 trials, was administered to 21 high-functioning adolescents and adults with autism spectrum disorder (ASD) and 21 matched typical individuals. The groups showed similar overall levels of free recall, rates of learning over trials and subjective organisation of their recall. However, the primacy portion of the serial position curve of the ASD participants showed slower growth over trials than that of the typical participants. The implications of this finding for our understanding of memory in ASD are discussed.

Titre : Enhanced connectivity between visual cortex and other regions of the brain in autism: a REM sleep EEG coherence study Type de document : Texte imprimé et/ou numérique Auteurs : Cathy LEVEILLE, Auteur ; Elise B. BARBEAU, Auteur ; Christianne BOLDUC, Auteur ; Elyse LIMOGES, Auteur ; Claude BERTHIAUME, Auteur ; Elyse CHEVRIER, Auteur ; Laurent MOTTRON, Auteur ; Roger GODBOUT, Auteur Année de publication : 2010 Article en page(s) : p.280-285 Langues : Anglais (eng) Mots-clés : autism occipital cortex REM sleep EEG EEG coherence visual perception neural coupling Index. décimale : PER Périodiques Résumé : Functional interregional neural coupling was measured as EEG coherence during REM sleep, a state of endogenous cortical activation, in 9 adult autistic individuals (21.1±4.0 years) and 13 typically developed controls (21.5±4.3 years) monitored for two consecutive nights in a sleep laboratory. Spectral analysis was performed on 60 s of artefact-free EEG samples distributed equally throughout the first four REM sleep periods of the second night. EEG coherence was calculated for six frequency bands (delta, theta, alpha, sigma, beta, and total spectrum) using a 22-electrode montage. The magnitude of coherence function was computed for intra- and interhemispheric pairs of recording sites. Results were compared by Multivariate Analysis of Variance (MANOVA). Each time the autistic group showed a greater EEG coherence than the controls; it involved intrahemispheric communication among the left visual cortex (O1) and other regions either close to or distant from the occipital cortex. In contrast, lower coherence values involved frontal electrodes in the right hemisphere. No significant differences between groups were found for interhemispheric EEG coherence. These results show that the analysis of EEG coherence during REM sleep can disclose patterns of cortical connectivity that can be reduced or increased in adults with autism compared to typically developed individuals, depending of the cortical areas studied. Superior coherence involving visual perceptual areas in autism is consistent with an enhanced role of perception in autistic brain organization.
