Attention to Faces in Williams Syndrome / Deborah M. RIBY in Journal of Autism and Developmental Disorders, 41-9 (September 2011)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 41-9 (September 2011) . - p.1228-1239 Titre : Attention to Faces in Williams Syndrome Type de document : texte imprimé Auteurs : Deborah M. RIBY, Auteur ; Nicola JONES, Auteur ; Philippa H. BROWN, Auteur ; Lucy J. ROBINSON, Auteur ; Stephen R.H. LANGTON, Auteur ; Vicki BRUCE, Auteur ; Leigh M. RIBY, Auteur Année de publication : 2011 Article en page(s) : p.1228-1239 Langues : Anglais (eng) Mots-clés : Williams syndrome  Social attention  Face perception  Autism Index. décimale : PER Périodiques Résumé : Williams syndrome (WS) is associated with distinct social behaviours. One component of the WS social phenotype is atypically prolonged face fixation. This behaviour co-exists with attention difficulties. Attention is multi-faceted and may impact on gaze behaviour in several ways. Four experiments assessed (i) attention capture by faces, (ii) interference from facial stimuli, (iii) face bias, and (iv) attention disengagement. Individuals with WS were compared to typically developing participants of comparable nonverbal ability and chronological age. The first three experiments revealed no atypicality of attention to faces in WS. However, in experiment 4 there was a suggestion that individuals with WS (compared to those developing typically) found it much more time consuming to disengage from faces than objects. The results are discussed in terms of attention abnormalities and possible face disengagement difficulties in WS.

Atypical Face Perception in Autism: A Point of View? / Karine MORIN in Autism Research, 8-5 (October 2015)  

Public ISBD [article]  inAutism Research > 8-5 (October 2015) . - p.497-506 Titre : Atypical Face Perception in Autism: A Point of View? Type de document : texte imprimé Auteurs : Karine MORIN, Auteur ; Jacalyn GUY, Auteur ; Claudine HABAK, Auteur ; Hugh R. WILSON, Auteur ; Linda PAGANI, Auteur ; Laurent MOTTRON, Auteur ; Armando BERTONE, Auteur Article en page(s) : p.497-506 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  face perception  local  global  synthetic faces  viewpoint change Index. décimale : PER Périodiques Résumé : Face perception is the most commonly used visual metric of social perception in autism. However, when found to be atypical, the origin of face perception differences in autism is contentious. One hypothesis proposes that a locally oriented visual analysis, characteristic of individuals with autism, ultimately affects performance on face tasks where a global analysis is optimal. The objective of this study was to evaluate this hypothesis by assessing face identity discrimination with synthetic faces presented with and without changes in viewpoint, with the former condition minimizing access to local face attributes used for identity discrimination. Twenty-eight individuals with autism and 30 neurotypical participants performed a face identity discrimination task. Stimuli were synthetic faces extracted from traditional face photographs in both front and 20° side viewpoints, digitized from 37 points to provide a continuous measure of facial geometry. Face identity discrimination thresholds were obtained using a two-alternative, temporal forced choice match-to-sample paradigm. Analyses revealed an interaction between group and condition, with group differences found only for the viewpoint change condition, where performance in the autism group was decreased compared to that of neurotypical participants. The selective decrease in performance for the viewpoint change condition suggests that face identity discrimination in autism is more difficult when access to local cues is minimized, and/or when dependence on integrative analysis is increased. These results lend support to a perceptual contribution of atypical face perception in autism. Autism Res 2015, 8: 497–506. © 2015 International Society for Autism Research, Wiley Periodicals, Inc.

Brain activity during facial processing in autism spectrum disorder: an activation likelihood estimation (ALE) meta-analysis of neuroimaging studies / Cristiano COSTA in Journal of Child Psychology and Psychiatry, 62-12 (December 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-12 (December 2021) . - p.1412-1424 Titre : Brain activity during facial processing in autism spectrum disorder: an activation likelihood estimation (ALE) meta-analysis of neuroimaging studies Type de document : texte imprimé Auteurs : Cristiano COSTA, Auteur ; Ioana A.

Therefore, we conducted an activation likelihood estimation (ALE) meta-analysis of studies examining brain activity during face processing. METHODS: We searched PubMed and PsycINFO using combinations of terms as 'fMRI', 'Autism Spectrum Disorder', 'Face Perception'. Eligible studies reported on DSM-diagnosed ASD individuals, compared to controls (HC), using face stimuli presented in fMRI and reporting whole-brain analysis coordinates. We compared two approaches: 'convergence of differences' (primary analysis) using study-level coordinates from ASD vs. HC contrasts, and 'differences in convergence' (secondary) pooling coordinates within each group separately, and contrasting the resultant ALE maps. RESULTS: Thirty-five studies (655 ASD and 668 HC) were included. Primary analysis identified a cluster in amygdala/parahippocampus where HC showed greater convergence of activation. Secondary analysis yielded no significant results. CONCLUSIONS: Results suggest that ASD dysfunction in face processing relies on structures involved in emotional processing rather than perception. We also demonstrate that the two ALE methodologies lead to divergent results.

Brief Report: Faces Cause Less Distraction in Autism / Deborah M. RIBY in Journal of Autism and Developmental Disorders, 42-4 (April 2012)

When faces need to be processed for meaning they fail to capture and hold the attention of individuals with autism. In the current study we illustrate that faces fail to capture attention in a typical manner even when they are non-functional to task completion. In a visual search task with a present butterfly target an irrelevant face distracter significantly slows performance of typical individuals. However, participants with autism (n = 28; mean 10 years 4 months) of comparable non-verbal ability are not distracted by the faces. Interestingly, there is a significant relationship between level of functioning on the autism spectrum and degree of face capture or distraction.

Brief Report: Seeing the Man in the Moon: Do Children with Autism Perceive Pareidolic Faces? A Pilot Study / Christian RYAN in Journal of Autism and Developmental Disorders, 46-12 (December 2016)

Autism spectrum disorder (ASD) is characterised by deficits in response to social stimuli. We found that children with ASD (n = 60) identify significantly fewer pareidolic faces in a sequence of ambiguous stimuli than typically developing peers. The two groups did not differ in the number of objects identified, indicating that the children with ASD had a specific lack of attention to faces. Pareidolia have considerable potential as naturalistic and easy-to-create materials for the investigation of spontaneous attention to social stimuli in children with ASD.
