PORTER, Auteur ; Max COLTHEART, Auteur ; Robyn LANGDON, Auteur Année de publication : 2008 Article en page(s) : 806-814 Langues : Anglais (eng) Mots-clés : Williams-syndrome Theory-of Mind-(ToM) Nonverbal Heterogeneity Index. décimale : PER Périodiques Résumé : This study examined Theory of Mind in Williams syndrome (WS) and in normal chronological age-matched and mental age-matched control groups, using a picture sequencing task. This task assesses understanding of pretence, intention and false belief, while controlling for social-script knowledge and physical cause-and-effect reasoning. The task was selected because it is entirely non-verbal, so that the WS individuals could not rely on their good verbal skills when performing the task. Results indicated a specific deficit in understanding of false belief within the WS group. There was also evidence of heterogeneity in the WS group, with the false belief impairment restricted to only a particular subgroup of WS individuals identified originally by Porter, M., & Coltheart, M. (2005). Cognitive heterogeneity in Williams syndrome. Developmental Neuropsychology, 27(2), 275–306.

Viewing Social Scenes: A Visual Scan-Path Study Comparing Fragile X Syndrome and Williams Syndrome / Tracey A. WILLIAMS in Journal of Autism and Developmental Disorders, 43-8 (August 2013)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 43-8 (August 2013) . - p.1880-1894 Titre : Viewing Social Scenes: A Visual Scan-Path Study Comparing Fragile X Syndrome and Williams Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Tracey A. WILLIAMS, Auteur ; Melanie A. PORTER, Auteur ; Robyn LANGDON, Auteur Article en page(s) : p.1880-1894 Langues : Anglais (eng) Mots-clés : Fragile X syndrome  FXS  Williams syndrome  WS  Social processing  Attentional disengagement  Attentional capture  Eye-tracking Index. décimale : PER Périodiques Résumé : Fragile X syndrome (FXS) and Williams syndrome (WS) are both genetic disorders which present with similar cognitive-behavioral problems, but distinct social phenotypes. Despite these social differences both syndromes display poor social relations which may result from abnormal social processing. This study aimed to manipulate the location of socially salient information within scenes to investigate the visual attentional mechanisms of: capture, disengagement, and/or general engagement. Findings revealed that individuals with FXS avoid social information presented centrally, at least initially. The WS findings, on the other hand, provided some evidence that difficulties with attentional disengagement, rather than attentional capture, may play a role in the WS social phenotype. These findings are discussed in relation to the distinct social phenotypes of these two disorders.
