Do Planning and Visual Integration Difficulties Underpin Motor Dysfunction in Autism? A Kinematic Study of Young Children with Autism / Ariane M. DOWD in Journal of Autism and Developmental Disorders, 42-8 (August 2012)

Titre : Do Planning and Visual Integration Difficulties Underpin Motor Dysfunction in Autism? A Kinematic Study of Young Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Ariane M. DOWD, Auteur ; Jennifer L. MCGINLEY, Auteur ; John R. TAFFE, Auteur ; Nicole J. RINEHART, Auteur Année de publication : 2012 Article en page(s) : p.1539-1548 Langues : Anglais (eng) Mots-clés : Autism Motor processes Movement kinematics Motor preparation Visual integration Index. décimale : PER Périodiques Résumé : This paper examines the upper-limb movement kinematics of young children (3–7 years) with high-functioning autism using a point-to-point movement paradigm. Consistent with prior findings in older children, a difference in movement preparation was found in the autism group (n = 11) relative to typically developing children. In contrast to typically developing children, the presence of a visual distractor in the movement task did not appear to impact on early movement planning or execution in children with autism, suggesting that this group were not considering all available environmental cues to modulate movement. The findings from this study are consistent with the possibility that autism is associated with a difficulty using visual information to prime alternative movements in a responsive way to environmental demands.

Titre : Visual perception and processing in children with 22q11.2 deletion syndrome: associations with social cognition measures of face identity and emotion recognition Type de document : Texte imprimé et/ou numérique Auteurs : K. L. MCCABE, Auteur ; S. MARLIN, Auteur ; Gavin COOPER, Auteur ; R. MORRIS, Auteur ; U. SCHALL, Auteur ; D. G. MURPHY, Auteur ; K. C. MURPHY, Auteur ; Linda E. CAMPBELL, Auteur Article en page(s) : p.30 Langues : Anglais (eng) Mots-clés : 22q11.2 deletion syndrome (22q11DS) Face processing Object recognition Perceptual organisation Social cognition Visual integration Index. décimale : PER Périodiques Résumé : BACKGROUND: People with 22q11.2 deletion syndrome (22q11DS) have difficulty processing social information including facial identity and emotion processing. However, difficulties with visual and attentional processes may play a role in difficulties observed with these social cognitive skills. METHODS: A cross-sectional study investigated visual perception and processing as well as facial processing abilities in a group of 49 children and adolescents with 22q11DS and 30 age and socio-economic status-matched healthy sibling controls using the Birmingham Object Recognition Battery and face processing sub-tests from the MRC face processing skills battery. RESULTS: The 22q11DS group demonstrated poorer performance on all measures of visual perception and processing, with greatest impairment on perceptual processes relating to form perception as well as object recognition and memory. In addition, form perception was found to make a significant and unique contribution to higher order social-perceptual processing (face identity) in the 22q11DS group. CONCLUSIONS: The findings indicate evidence for impaired visual perception and processing capabilities in 22q11DS. In turn, these were found to influence cognitive skills needed for social processes such as facial identity recognition in the children with 22q11DS.
