Brief Report: Imitation of Meaningless Gestures in Individuals with Asperger Syndrome and High-functioning Autism / Heidi STIEGLITZ HAM in Journal of Autism and Developmental Disorders, 38-3 (March 2008)

The individuals with AS/HFA achieved lower scores in the imitation of both hand and finger positions relative to a matched neurotypical group. The between-group difference was primarily accounted for by performance on a test of visual motor integration, together with a hand imitation deficit which was specifically due to errors in body part orientation. Our findings implicate both visuomotor processes (Damasio and Maurer, 1978) and self-other mapping (Rogers and Pennington, 1991) in ASD imitation deficits. Following Goldenberg (1999), we propose that difficulties with body part orientation may underlie problems in meaningless gesture imitation.

Exploring the Relationship Between Gestural Recognition and Imitation: Evidence of Dyspraxia in Autism Spectrum Disorders / Heidi STIEGLITZ HAM in Journal of Autism and Developmental Disorders, 41-1 (January 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-1 (January 2011) . - p.1-12 Titre : Exploring the Relationship Between Gestural Recognition and Imitation: Evidence of Dyspraxia in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Heidi STIEGLITZ HAM, Auteur ; Angela BARTOLO, Auteur ; Martin CORLEY, Auteur ; Gnanathusharan RAJENDRAN, Auteur ; Aniko SZABO, Auteur ; Sara SWANSON, Auteur Année de publication : 2011 Article en page(s) : p.1-12 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders  Dyspraxia  Gestural recognition  Imitation Index. décimale : PER Périodiques Résumé : In this study, the relationship between gesture recognition and imitation was explored. Nineteen individuals with Autism Spectrum Disorder (ASD) were compared to a control group of 23 typically developing children on their ability to imitate and recognize three gesture types (transitive, intransitive, and pantomimes). The ASD group performed more poorly than controls on all tasks of recognition and imitation. Higher performance on tests of working memory was associated with increased odds of successful imitation in both groups. Group differences remained even when working memory was statistically controlled for. An association was revealed in the ASD group between pantomime recognition and imitation but a similar association was not identified for intransitive gestures suggesting that recognition alone is not sufficient for imitation success.
