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)

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.

Speaker-Versus Listener-Oriented Disfluency: A Re-examination of Arguments and Assumptions from Autism Spectrum Disorder / Paul E. ENGELHARDT in Journal of Autism and Developmental Disorders, 47-9 (September 2017)

Previous studies examined individuals with HFA to address a theoretical question regarding speaker- and listener-oriented disfluencies. Individuals with HFA tend to be self-centric and have poor pragmatic language skills, and should be less likely to produce listener-oriented disfluency. However, previous studies did not account for individual differences variables that affect disfluency. We show that both matched and unmatched controls produce fewer repairs than individuals with HFA. For silent pauses, there was no difference between matched controls and HFA, but both groups produced more than unmatched controls. These results identify limitations in prior research and shed light on the relationship between autism spectrum disorders and disfluent speech.

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.
