Atypical Processing of Gaze Cues and Faces Explains Comorbidity between Autism Spectrum Disorder (ASD) and Attention Deficit/Hyperactivity Disorder (ADHD) / Madeleine J. GROOM in Journal of Autism and Developmental Disorders, 47-5 (May 2017)
[article]
Titre : Atypical Processing of Gaze Cues and Faces Explains Comorbidity between Autism Spectrum Disorder (ASD) and Attention Deficit/Hyperactivity Disorder (ADHD) Type de document : Texte imprimé et/ou numérique Auteurs : Madeleine J. GROOM, Auteur ; Puja KOCHHAR, Auteur ; Antonia HAMILTON, Auteur ; Elizabeth B. LIDDLE, Auteur ; Marina SIMEOU, Auteur ; Chris HOLLIS, Auteur Article en page(s) : p.1496-1509 Langues : Anglais (eng) Mots-clés : ASD ADHD ERPs Comorbidity Gaze cueing Face processing Index. décimale : PER Périodiques Résumé : This study investigated the neurobiological basis of comorbidity between autism spectrum disorder (ASD) and attention deficit/hyperactivity disorder (ADHD). We compared children with ASD, ADHD or ADHD+ASD and typically developing controls (CTRL) on behavioural and electrophysiological correlates of gaze cue and face processing. We measured effects of ASD, ADHD and their interaction on the EDAN, an ERP marker of orienting visual attention towards a spatially cued location and the N170, a right-hemisphere lateralised ERP linked to face processing. We identified atypical gaze cue and face processing in children with ASD and ADHD+ASD compared with the ADHD and CTRL groups. The findings indicate a neurobiological basis for the presence of comorbid ASD symptoms in ADHD. Further research using larger samples is needed.

[article]
Titre : Body Constraints on Motor Simulation in Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Massimiliano CONSON, Auteur ; Antonia HAMILTON, Auteur ; Francesco BELLIS, Auteur ; Domenico ERRICO, Auteur ; Ilaria IMPROTA, Auteur ; Elisabetta MAZZARELLA, Auteur ; Luigi TROJANO, Auteur ; Alessandro FROLLI, Auteur Article en page(s) : p.1051-1060 Langues : Anglais (eng) Mots-clés : ASD Motor simulation Motor imagery Proprioception Mental transformation Development Index. décimale : PER Périodiques Résumé : Developmental data suggested that mental simulation skills become progressively dissociated from overt motor activity across development. Thus, efficient simulation is rather independent from current sensorimotor information. Here, we tested the impact of bodily (sensorimotor) information on simulation skills of adolescents with Autism Spectrum Disorders (ASD). Typically-developing (TD) and ASD participants judged laterality of hand images while keeping one arm flexed on chest or while holding both arms extended. Both groups were able to mentally simulate actions, but this ability was constrained by body posture more in ASD than in TD adolescents. The strong impact of actual body information on motor simulation implies that simulative skills are not fully effective in ASD individuals.

Titre : Brief Report: Autistic Adults Assign Less Weight to Affective Cues When Judging Others' Ambiguous Emotional States Type de document : Texte imprimé et/ou numérique Auteurs : Paul A. G. FORBES, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.3066-3070 Langues : Anglais (eng) Mots-clés : Emotions Faces Theory of mind Index. décimale : PER Périodiques Résumé : Understanding other people's emotional states involves integrating multiple sources of information, such as someone's smile (affective cue) with our knowledge that they have passed an exam (situational cue). We explored whether autistic adults display differences in how they integrate these cues by showing participants videos of students receiving their exams results. Our results suggest autistic adults generally perform as neurotypical participants when identifying and integrating affective and situational cues. It was only in certain unfamiliar and ambiguous social situations that autistic adults assigned less weight to affective cues compared to situational cues when judging other people's emotional states.

Here we compared adolescents with (N?=?31) and without (N?=?37) ASC on the Choose-a-Movie paradigm that measures the social seeking. The results showed a preference for viewing objects over smiling faces in ASC, which is in line with the theory of low social motivation. However, typical adolescents did not show any stimuli preferences, raising questions about developmental changes in social motivation. Age was found to play a significant role in moderating the choice behaviour of the participants. We discuss the implications of these findings in detail.

Titre : Cognitive Mechanisms underlying visual perspective taking in typical and ASC children Type de document : Texte imprimé et/ou numérique Auteurs : Amy PEARSON, Auteur ; Lauren MARSH, Auteur ; Danielle ROPAR, Auteur ; Antonia HAMILTON, Auteur Article en page(s) : p.121-130 Langues : Anglais (eng) Mots-clés : autism spectrum conditions visual perspective taking mental rotation embodied cognitive mechanisms Index. décimale : PER Périodiques Résumé : Previous research has suggested that people with Autism Spectrum Conditions (ASC) may have difficulty with visual perspective taking (VPT) but it is not clear how this relates to different strategies that can be used in perspective taking tasks. The current study examined VPT in 30 children with autism and 30 verbal mental age matched typical children, in comparison to mental rotation (MR) abilities and body representation abilities. Using a similar paradigm to Hamilton, Brindley, and Frith [2009] all children completed three tasks: a VPT task in which children decided what a toy on a table would look like from a different points of view; a MR task in which the child decided what a toy would look like after it had been rotated; and a body posture matching task, in which children matched pictures of a body shown from different viewpoints. Results showed that children with ASC performed better than the typically developing children on the MR task, and at a similar level on the VPT task and body matching task. Importantly, in the typical children VPT performance was predicted by performance on the body matching task, whereas in the ASC children VPT performance was predicted by MR ability. These findings suggest that differences in VPT in ASC may be explained by the use of a spatial rotation strategy rather than the embodied egocentric transformation strategy used by typical children.
