Attention to Faces in Williams Syndrome / Deborah M. RIBY in Journal of Autism and Developmental Disorders, 41-9 (September 2011)

One component of the WS social phenotype is atypically prolonged face fixation. This behaviour co-exists with attention difficulties. Attention is multi-faceted and may impact on gaze behaviour in several ways. Four experiments assessed (i) attention capture by faces, (ii) interference from facial stimuli, (iii) face bias, and (iv) attention disengagement. Individuals with WS were compared to typically developing participants of comparable nonverbal ability and chronological age. The first three experiments revealed no atypicality of attention to faces in WS. However, in experiment 4 there was a suggestion that individuals with WS (compared to those developing typically) found it much more time consuming to disengage from faces than objects. The results are discussed in terms of attention abnormalities and possible face disengagement difficulties in WS.

Brief Report: Faces Cause Less Distraction in Autism / Deborah M. RIBY in Journal of Autism and Developmental Disorders, 42-4 (April 2012)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 42-4 (April 2012) . - p.634-639 Titre : Brief Report: Faces Cause Less Distraction in Autism Type de document : Texte imprimé et/ou numérique Auteurs : Deborah M. RIBY, Auteur ; Philippa H. BROWN, Auteur ; Nicola JONES, Auteur ; Mary HANLEY, Auteur Année de publication : 2012 Article en page(s) : p.634-639 Langues : Anglais (eng) Mots-clés : Face perception  Social attention  Autism Index. décimale : PER Périodiques Résumé : Individuals with autism have difficulties interpreting face cues that contribute to deficits of social communication. When faces need to be processed for meaning they fail to capture and hold the attention of individuals with autism. In the current study we illustrate that faces fail to capture attention in a typical manner even when they are non-functional to task completion. In a visual search task with a present butterfly target an irrelevant face distracter significantly slows performance of typical individuals. However, participants with autism (n = 28; mean 10 years 4 months) of comparable non-verbal ability are not distracted by the faces. Interestingly, there is a significant relationship between level of functioning on the autism spectrum and degree of face capture or distraction.
