This study aimed to develop understanding of the nature and role of over-selectivity in autism spectrum disorder (ASD) by analyzing the relationship of over-selectivity to core deficits of ASD: stereotyped responding and inflexibility. Over-selectivity was investigated in a visual discrimination task in 24 children, 12 diagnosed with ASD and 12 mental-age-matched typically developing children. In addition, the participants’ levels of intellectual functioning, stereotypy, and cognitive flexibility were assessed using established tools. Results showed that over-selectivity was associated with IQ and stereotyped behavior but was not related to levels of cognitive flexibility nor did cognitive flexibility significantly correlate with stereotyped behavior in individuals with ASD. The current findings require consideration when designing behavioral interventions for individuals with ASD.

Stimulus Over-Selectivity and Extinction-Induced Recovery of Performance as a Product of Intellectual Impairment and Autism Severity / Michelle P. KELLY in Journal of Autism and Developmental Disorders, 45-10 (October 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-10 (October 2015) . - p.3098-3106 Titre : Stimulus Over-Selectivity and Extinction-Induced Recovery of Performance as a Product of Intellectual Impairment and Autism Severity Type de document : texte imprimé Auteurs : Michelle P. KELLY, Auteur ; Geraldine LEADER, Auteur ; Phil REED, Auteur Article en page(s) : p.3098-3106 Langues : Anglais (eng) Mots-clés : Over-selectivity  Extinction  Comparator deficit  Intellectual impairment  Autism severity Index. décimale : PER Périodiques Résumé : The current experiment investigated the extent to which three variables (autism severity, nonverbal intellectual functioning, and verbal intellectual functioning) are associated with over-selective responding in a group of children with Autism Spectrum Disorder. This paper also analyzed the association of these three variables with the recovery of responding to a previously under-selected stimulus following extinction of the previously over-selected stimulus. The results demonstrated that participants showed over-selectivity, and demonstrated that extinction of the over-selected stimulus led to recovery of responding to the previously under-selected stimulus. For both over-selectivity, and recovery from over-selectivity, verbal functioning appeared to predict the effects most strongly, with greater over-selectivity in the lower functioning individuals, and greater recovery in the higher functioning individuals.
