Cognitive Flexibility in ASD; Task Switching with Emotional Faces / Marieke VRIES in Journal of Autism and Developmental Disorders, 42-12 (December 2012)
[article]
Titre : Cognitive Flexibility in ASD; Task Switching with Emotional Faces Type de document : Texte imprimé et/ou numérique Auteurs : Marieke VRIES, Auteur ; Hilde M. GEURTS, Auteur Année de publication : 2012 Article en page(s) : p.2558-2568 Langues : Anglais (eng) Mots-clés : ASD Task switching Cognitive flexibility Emotion Executive functioning Index. décimale : PER Périodiques Résumé : Children with autism spectrum disorders (ASDs) show daily cognitive flexibility deficits, but laboratory data are unconvincing. The current study aimed to bridge this gap. Thirty-one children with ASD (8'12 years) and 31 age- and IQ-matched typically developing children performed a gender emotion switch task. Unannounced switches and complex stimuli (emotional faces) improved ecological validity; minimal working memory-load prevented bias in the findings. Overall performance did not differ between groups, but in a part of the ASD group performance was slow and inaccurate. Moreover, within the ASD group switching from emotion to gender trials was slower than vice versa. Children with ASD do not show difficulties on an ecological valid switch task, but have difficulty disengaging from an emotional task set.

Titre : Understanding Behavioural Rigidity in Autism Spectrum Conditions: The Role of Intentional Control Type de document : Texte imprimé et/ou numérique Auteurs : Edita POLJAC, Auteur ; Vincent HOOFS, Auteur ; Myrthe M. PRINCEN, Auteur ; Ervin POLJAC, Auteur Article en page(s) : p.714-727 Langues : Anglais (eng) Mots-clés : Cognitive control Autism Intentions Task switching Voluntary action Index. décimale : PER Périodiques Résumé : Although behavioural rigidity belongs to the core symptoms of autism spectrum conditions, little is known about its underlying cognitive mechanisms. The current study investigated the role of intentional control mechanisms in behavioural rigidity in autism. Autistic individuals and their matched controls were instructed to repeatedly choose between two simple cognitive tasks and to respond accordingly to the subsequently presented stimulus. Results showed that autistic participants chose to repeat tasks more often than their controls and when choosing to switch, they demonstrated larger performance costs. These findings illustrate that when required to make their own choices, autistic people demonstrate rigidity at different performance levels, suggesting that intentional control mechanisms might be important for a better understanding of behavioural rigidity in autism.
