Familiar Face Recognition in Children with Autism: The Differential use of Inner and Outer Face Parts / Rebecca WILSON in Journal of Autism and Developmental Disorders, 37-2 (February 2007)
[article]
Titre : Familiar Face Recognition in Children with Autism: The Differential use of Inner and Outer Face Parts Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca WILSON, Auteur ; Olivier PASCALIS, Auteur ; Mark BLADES, Auteur Année de publication : 2007 Article en page(s) : p.314-320 Langues : Anglais (eng) Mots-clés : Autism Children Familiar-face Part-face Index. décimale : PER Périodiques Résumé : We investigated whether children with autistic spectrum disorders (ASD) have a deficit in recognising familiar faces. Children with ASD were given a forced choice familiar face recognition task with three conditions: full faces, inner face parts and outer face parts. Control groups were children with developmental delay (DD) and typically developing (TD) children. Children with ASD and children with DD recognised slightly fewer faces than did TD children, but there was no ASD-specific deficit. All groups displayed the same pattern of face part superiority: full-face superiority over inner face, and inner face superiority over outer face. Therefore, the pattern of familiar face recognition by children with ASD was similar to the pattern found in other children.

Titre : Route knowledge and configural knowledge in typical and atypical development: a comparison of sparse and rich environments Type de document : Texte imprimé et/ou numérique Auteurs : E. K. FARRAN, Auteur ; H. R. PURSER, Auteur ; Y. COURBOIS, Auteur ; M. BALLE, Auteur ; P. SOCKEEL, Auteur ; D. MELLIER, Auteur ; Mark BLADES, Auteur Article en page(s) : p.37 Langues : Anglais (eng) Mots-clés : Development Down syndrome Navigation Spatial cognition Williams syndrome Index. décimale : PER Périodiques Résumé : BACKGROUND: Individuals with Down syndrome (DS) and individuals with Williams syndrome (WS) have poor navigation skills, which impact their potential to become independent. Two aspects of navigation were investigated in these groups, using virtual environments (VE): route knowledge (the ability to learn the way from A to B by following a fixed sequence of turns) and configural knowledge (knowledge of the spatial relationships between places within an environment). METHODS: Typically developing (TD) children aged 5 to 11 years (N = 93), individuals with DS (N = 29) and individuals with WS (N = 20) were presented with a sparse and a rich VE grid maze. Within each maze, participants were asked to learn a route from A to B and a route from A to C before being asked to find a novel shortcut from B to C. RESULTS: Performance was broadly similar across sparse and rich mazes. The majority of participants were able to learn novel routes, with poorest performance in the DS group, but the ability to find a shortcut, our measure of configural knowledge, was limited for all three groups. That is, 59 % TD participants successfully found a shortcut, compared to 10 % participants with DS and 35 % participants with WS. Differences in the underlying mechanisms associated with route knowledge and configural knowledge and in the developmental trajectories of performance across groups were observed. Only the TD participants walked a shorter distance in the last shortcut trial compared to the first, indicative of increased configural knowledge across trials. The DS group often used an alternative strategy to get from B to C, summing the two taught routes together. CONCLUSIONS: Our findings demonstrate impaired configural knowledge in DS and in WS, with the strongest deficit in DS. This suggests that these groups rely on a rigid route knowledge based method for navigating and as a result are likely to get lost easily. Route knowledge was also impaired in both DS and WS groups and was related to different underlying processes across all three groups. These are discussed with reference to limitations in attention and/or visuo-spatial processing in the atypical groups.
