Public ISBD [article]  inJournal of Autism and Developmental Disorders > 39-2 (February 2009) . - p.330-338 Titre : The Effect of Stimulus Salience on Over-selectivity Type de document : Texte imprimé et/ou numérique Auteurs : Geraldine LEADER, Auteur ; Phil REED, Auteur ; Ann LOUGHNANE, Auteur ; Claire MCMORELAND, Auteur Année de publication : 2009 Article en page(s) : p.330-338 Langues : Anglais (eng) Mots-clés : Over-selectivity Comparator-mechanism Stimulus-salience Extinction Index. décimale : PER Périodiques Résumé : The influence of stimulus salience on over-selective responding was investigated in the context of a comparator theory of over-selectivity. In Experiments 1 and 2, participants were presented with two cards, each displaying two colors. In comparison to matched control participants, participants with Autistic Spectrum Disorder (ASD) demonstrated more over-selectivity, which increased when the stimuli differed in salience. In Experiment 3, the over-selected color was extinguished, and the previously under-selected color emerged to control behavior. The results suggest that stimuli of different salience may trigger over-selectivity in individuals with ASD, and provide preliminary support that this may be due to the action of an over-sensitive comparator mechanism functioning at the retrieval level of processing.
