Research review: Goals, intentions and mental states: challenges for theories of autism / Antonia HAMILTON in Journal of Child Psychology and Psychiatry, 50-8 (August 2009)
[article]
Titre : Research review: Goals, intentions and mental states: challenges for theories of autism Type de document : Texte imprimé et/ou numérique Auteurs : Antonia HAMILTON, Auteur Année de publication : 2009 Article en page(s) : p.881-892 Langues : Anglais (eng) Mots-clés : Autistic-disorder brain-imaging cognition theory-of-mind Index. décimale : PER Périodiques Résumé : The ability to understand the goals and intentions behind other people's actions is central to many social interactions. Given the profound social difficulties seen in autism, we might expect goal understanding to be impaired in these individuals. Two influential theories, the 'broken mirror' theory and the mentalising theory, can both predict this result. However, a review of the current data provides little empirical support for goal understanding difficulties; several studies demonstrate normal performance by autistic children on tasks requiring the understanding of goals or intentions. I suggest that this conclusion forces us to reject the basic broken mirror theory and to re-evaluate the breadth of the mentalising theory. More subtle theories which distinguish between different types of mirroring and different types of mentalising may be able to account for the present data, and further research is required to test and refine these theories.

[article]
Titre : Social anxiety is more likely to influence reputation management decisions than autistic traits Type de document : Texte imprimé et/ou numérique Auteurs : Maddie GROOM, Auteur ; Ameena TAHIR, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.78-88 Index. décimale : PER Périodiques Résumé : Abstract People manage their social reputation by selectively sharing achievements, thereby shaping the way others think about them. Autistic traits and social anxiety may have opposing impacts on reputation management. This study aimed to identify the influence of autistic traits and social anxiety on reputation management behavior, independently and in co-occurrence with one another. Seventy-seven adults with varying levels of autistic and social anxiety traits completed a novel self-disclosure task that required them to complete a computerized game and decide whether to disclose their scores to another participant. This design provided a safe social environment for sharing performance outcomes and allowed us to manipulate performance outcomes for participants and set a perceived ?norm? of high self-disclosure. Results showed that participants were more likely to disclose their high than low scores to the other player. Social anxiety reliably predicted the likelihood of disclosing their scores while high autistic traits predicted the likelihood of disclosure only in combination with high social anxiety. Additionally, establishing the norm of high disclosure facilitated self-disclosure in all the participants. This study shows that social anxiety may influence reputation management via selective self-disclosure more when co-occurring with high autistic traits. People with varying levels of autistic traits may not behave differently to maintain a social reputation.

[article]
Titre : Spatial Transformations of Bodies and Objects in Adults with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Amy PEARSON, Auteur ; Lauren MARSH, Auteur ; Antonia HAMILTON, Auteur ; Danielle ROPAR, Auteur Article en page(s) : p.2277-2289 Langues : Anglais (eng) Mots-clés : Spatial transformations Bodies Objects Mental rotation Egocentric Autism Index. décimale : PER Périodiques Résumé : Previous research into autism spectrum disorder (ASD) has shown people with autism to be impaired at visual perspective taking. However it is still unclear to what extent the spatial mechanisms underlying this ability contribute to these difficulties. In the current experiment we examine spatial transformations in adults with ASD and typical adults. Participants performed egocentric transformations and mental rotation of bodies and cars. Results indicated that participants with ASD had general perceptual differences impacting on response times across tasks. However, they also showed more specific differences in the egocentric task suggesting particular difficulty with using the self as a reference frame. These findings suggest that impaired perspective taking could be grounded in difficulty with the spatial transformation used to imagine the self in someone else’s place.

Titre : Typical use of inverse dynamics in perceiving motion in autistic adults: Exploring computational principles of perception and action Type de document : Texte imprimé et/ou numérique Auteurs : S. TAKAMUKU, Auteur ; P. A. G. FORBES, Auteur ; Antonia HAMILTON, Auteur ; H. GOMI, Auteur Article en page(s) : p.1062-1075 Langues : Anglais (eng) Mots-clés : autism delayed visual feedback internal models inverse dynamics velocity perception Index. décimale : PER Périodiques Résumé : There is increasing evidence for motor difficulties in many people with autism spectrum condition (ASC). These difficulties could be linked to differences in the use of internal models which represent relations between motions and forces/efforts. The use of these internal models may be dependent on the cerebellum which has been shown to be abnormal in autism. Several studies have examined internal computations of forward dynamics (motion from force information) in autism, but few have tested the inverse dynamics computation, that is, the determination of force-related information from motion information. Here, we examined this ability in autistic adults by measuring two perceptual biases which depend on the inverse computation. First, we asked participants whether they experienced a feeling of resistance when moving a delayed cursor, which corresponds to the inertial force of the cursor implied by its motion-both typical and ASC participants reported similar feelings of resistance. Second, participants completed a psychophysical task in which they judged the velocity of a moving hand with or without a visual cue implying inertial force. Both typical and ASC participants perceived the hand moving with the inertial cue to be slower than the hand without it. In both cases, the magnitude of the effects did not differ between the two groups. Our results suggest that the neural systems engaged in the inverse dynamics computation are preserved in ASC, at least in the observed conditions. Autism Res 2018, 11: 1062-1075. (c) 2018 International Society for Autism Research, Wiley Periodicals, Inc. LAY SUMMARY: We tested the ability to estimate force information from motion information, which arises from a specific "inverse dynamics" computation. Autistic adults and a matched control group reported feeling a resistive sensation when moving a delayed cursor and also judged a moving hand to be slower when it was pulling a load. These findings both suggest that the ability to estimate force information from motion information is intact in autism.
