Anticipation of Action Intentions in Autism Spectrum Disorder / Matthew HUDSON in Journal of Autism and Developmental Disorders, 42-8 (August 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-8 (August 2012) . - p.1684-1693 Titre : Anticipation of Action Intentions in Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Matthew HUDSON, Auteur ; Hollie G. BURNETT, Auteur ; Tjeerd JELLEMA, Auteur Année de publication : 2012 Article en page(s) : p.1684-1693 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  Gaze direction  Action anticipation  Representational momentum  Motor intention  Goal directed action Index. décimale : PER Périodiques Résumé : We investigated whether individuals with a mild form of autism spectrum disorder (ASD) are influenced by an actor’s gaze direction when anticipating how an observed action will continue in the immediate future. Participants observed a head rotate towards them, while the gaze direction was either leading, or lagging behind, rotation. They also observed identical rotations of a cylinder containing the geometrical equivalent of the gaze manipulation. The control group was influenced by the gaze manipulations for the animate but not the inanimate stimulus. The ASD group did not discriminate between the stimuli, showing a similar influence for both. This suggests that the ASD responses in the animate condition were biased by the low-level directional features of the eyes rather than by the conveyed intentions.

Implicit Social Learning in Relation to Autistic-Like Traits / Matthew HUDSON in Journal of Autism and Developmental Disorders, 42-12 (December 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-12 (December 2012) . - p.2534-2545 Titre : Implicit Social Learning in Relation to Autistic-Like Traits Type de document : Texte imprimé et/ou numérique Auteurs : Matthew HUDSON, Auteur ; Tanja C. W. NIJBOER, Auteur ; Tjeerd JELLEMA, Auteur Année de publication : 2012 Article en page(s) : p.2534-2545 Langues : Anglais (eng) Mots-clés : Intention  Gaze direction  Autism spectrum  Emotional expression  Gaze cueing  Implicit learning Index. décimale : PER Périodiques Résumé : We investigated if variation in autistic traits in the typically-developed population (using the Autism-spectrum Quotient, AQ) influenced implicit learning of social information. In the learning phase, participants repeatedly observed two identities whose gaze and expression conveyed either a pro- or antisocial disposition. These identities were then employed in a gaze-cueing paradigm. Participants made speeded responses to a peripheral target that was spatially pre-cued by a non-predictive gaze direction. The low AQ group (n = 50) showed a smaller gaze-cueing effect for the antisocial than for the prosocial identity. The high AQ group (n = 48) showed equivalent gaze-cueing for both identities. Others' intentions/dispositions can be learned implicitly and affect subsequent responses to their behavior. This ability is impaired with increasing levels of autistic traits.
