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 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.

Joint attention difficulties in autistic adults: An interactive eye-tracking study / Nathan CARUANA in Autism, 22-4 (May 2018)  

Public ISBD [article]  inAutism > 22-4 (May 2018) . - p.502-512 Titre : Joint attention difficulties in autistic adults: An interactive eye-tracking study Type de document : texte imprimé Auteurs : Nathan CARUANA, Auteur ; Heidi STIEGLITZ HAM, Auteur ; Jon BROCK, Auteur ; Alexandra WOOLGAR, Auteur ; Nadine KLOTH, Auteur ; Romina PALERMO, Auteur ; Genevieve MCARTHUR, Auteur Article en page(s) : p.502-512 Langues : Anglais (eng) Mots-clés : autism  eye gaze  eye tracking  joint attention  social interaction Index. décimale : PER Périodiques Résumé : Joint attention - the ability to coordinate attention with a social partner - is critical for social communication, learning and the regulation of interpersonal relationships. Infants and young children with autism demonstrate impairments in both initiating and responding to joint attention bids in naturalistic settings. However, little is known about joint attention abilities in adults with autism. Here, we tested 17 autistic adults and 17 age- and nonverbal intelligence quotient-matched controls using an interactive eye-tracking paradigm in which participants initiated and responded to joint attention bids with an on-screen avatar. Compared to control participants, autistic adults completed fewer trials successfully. They were also slower to respond to joint attention bids in the first block of testing but performed as well as controls in the second block. There were no group differences in responding to spatial cues on a non-social task with similar attention and oculomotor demands. These experimental results were mirrored in the subjective reports given by participants, with some commenting that they initially found it challenging to communicate using eye gaze, but were able to develop strategies that allowed them to achieve joint attention. Our study indicates that for many autistic individuals, subtle difficulties using eye-gaze information persist well into adulthood.
