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.

Investigating Multitasking in High-Functioning Adolescents with Autism Spectrum Disorders Using the Virtual Errands Task / Gnanathusharan RAJENDRAN in Journal of Autism and Developmental Disorders, 41-11 (November 2011)

The VET requires multitasking (Law et al. in Acta Psychol 122(1):27–44, 2006) because there is a limited amount of time in which to complete the errands. ANCOVA revealed that the ASD group completed fewer tasks, broke more rules and rigidly followed the task list in the order of presentation. Our findings suggest that executive problems of planning inflexibility, inhibition, as well as difficulties with prospective memory (remembering to carry out intentions) may lie behind multitasking difficulties in ASD.

Social self-efficacy and mental well-being in autistic adults: Exploring the role of social identity / Lorna CAMUS in Autism, 28-5 (May 2024)  

Public ISBD [article]  inAutism > 28-5 (May 2024) . - p.1258-1267 Titre : Social self-efficacy and mental well-being in autistic adults: Exploring the role of social identity Type de document : Texte imprimé et/ou numérique Auteurs : Lorna CAMUS, Auteur ; Gnanathusharan RAJENDRAN, Auteur ; Mary Elizabeth STEWART, Auteur Article en page(s) : p.1258-1267 Langues : Anglais (eng) Mots-clés : adults  autism  double empathy  homophily  mental well-being  social identity  social self-efficacy Index. décimale : PER Périodiques Résumé : The double empathy problem proposes a lack of shared understanding between autistic and non-autistic people leads to interaction difficulties between them. Social self-efficacy (confidence in one?s social abilities) makes an important contribution to social interactions. Research has shown that autistic people show a social identity (one?s sense of self based on membership of social groups) with other autistic people, and this impacts positively on well-being. In addition, research shows that autistic people have a number of social identities. This study aims to understand whether social self-efficacy relates to mental well-being in autistic adults, and whether social identity plays a role in this relationship. A total of 512 autistic adults completed measures of social self-efficacy, social identity, mental well-being and autistic traits. In-group social self-efficacy was found to be higher than out-group social self-efficacy. Second, in-group social self-efficacy was positively associated with well-being. Finally, social identity did not mediate the relationships between social self-efficacy and mental well-being. These findings suggest social self-efficacy may relate to the nature of the group one interacts with. The findings support further research into the relationship between social self-efficacy and well-being, as well as using the double empathy problem as a framework for further investigations in other social groups. Lay abstract In the past, research has suggested that autistic people are not able to communicate well with non-autistic people because of autistic people?s communication difficulties. However, newer theories question this conclusion. It is now thought that the communication difficulties may be because autistic and non-autistic people both struggle to understand each other. This study explores how these differences in shared understanding relate to autistic people?s mental well-being, confidence in social situations and social identities (groups that we belong to and that influence how we see ourselves). We created an online survey taken by 512 autistic adults, which included questions about their confidence being social with people from different groups (such as other autistic people or people they share a hobby with), about the social groups they felt they belong to and about their mental well-being. First, participants reported higher social confidence when interacting with members of a social group they belonged to. Second, being confident during these interactions was linked to higher mental well-being. Finally, the groups participants belonged to did not influence the link between social confidence and mental well-being. These findings are important as they help us better understand autistic people?s experiences of social interactions and what contributes to good and poor mental well-being in autistic people. They also help us to think further about how to improve autistic people?s well-being.

Strange Words: Autistic Traits and the Processing of Non-Literal Language / Peter E. MCKENNA in Journal of Autism and Developmental Disorders, 45-11 (November 2015)

Here we show how these confounds may be avoided, using data from non-diagnosed participants classified using Autism Quotient. Participants read sentences containing target words with novel or established metonymic senses (e.g., Finland, Vietnam) in literal- or figurative-supporting contexts. Participants took longer to read target words in figurative contexts, especially where the metonymic sense was novel. Importantly, participants with higher AQs took longer still to read novel metonyms. This suggests a focus for further exploration, in terms of potential differences between individuals diagnosed with ASD and their neurotypical counterparts, and more generally in terms of the processes by which comprehension is achieved.
