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)
[article]
Titre : Brief Report: Seeing the Man in the Moon: Do Children with Autism Perceive Pareidolic Faces? A Pilot Study Type de document : Texte imprimé et/ou numérique Auteurs : Christian RYAN, Auteur ; Martina STAFFORD, Auteur ; Robert James KING, Auteur Article en page(s) : p.3838-3843 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Face perception Social attention Protofacial stimuli Pareidolia Index. décimale : PER Périodiques Résumé : Faces are one of the most socially significant visual stimuli encountered in the environment, whereas pareidolias are illusions of faces arising from ambiguous stimuli in the environment. 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.

Titre : Eliciting Expressions of Emotion: An Exploratory Analysis of Alexithymia in Adults with Autism Utilising the APRQ : Journal of Autism and Developmental Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Christian RYAN, Auteur ; Stephen Cogan, Auteur Article en page(s) : p.2499-2513 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : This study examined alternative methods for detecting alexithymia to the Toronto Alexithymia Scale-20 (TAS-20) by comparing the emotional linguistic performance of ASD and NT samples (n=32 in each) on the Alexithymia Provoked Responses Questionnaire (APRQ). We utilised both the LIWC and tidytext approaches to linguistic analysis. The results indicate the ASD sample used significantly fewer affective words in response to emotionally stimulating scenarios and had less emotional granularity. Affective word use was correlated with ASD symptomatology but not with TAS-20 scores, suggesting that some elements of alexithymia are not well detected by the TAS-20 alone. The APRQ, in combination with the tidytext package, offers significant potential for sophisticated exploration of emotional expression in ASD.

Titre : Judgments of Nonverbal Behaviour by Children with High-Functioning Autism Spectrum Disorder: Can they Detect Signs of Winning and Losing from Brief Video Clips? Type de document : Texte imprimé et/ou numérique Auteurs : Christian RYAN, Auteur ; Philip FURLEY, Auteur ; Kathleen MULHALL, Auteur Article en page(s) : p.2916-2923 Langues : Anglais (eng) Mots-clés : Sport Emotion expression Nonverbal behavior Thin slices Autism Social rank Index. décimale : PER Périodiques Résumé : Typically developing children are able to judge who is winning or losing from very short clips of video footage of behaviour between active match play across a number of sports. Inferences from “thin slices” (short video clips) allow participants to make complex judgments about the meaning of posture, gesture and body language. This study extends the use of the thin slice research paradigm to children with high-functioning autism spectrum disorder (ASD). We tested 38 children with ASD, in two age groups: 15 participants aged 5–8 years and 23 participants aged 9–13 years. We found that the children with ASD had a rate of accuracy similar to that of typically developing peers tested in a previous study.

Titre : Teaching Emotion Recognition Skills to Children with Autism Type de document : Texte imprimé et/ou numérique Auteurs : Christian RYAN, Auteur ; Caitríona NI CHARRAGAIN, Auteur Année de publication : 2010 Article en page(s) : p.1505-1511 Langues : Anglais (eng) Mots-clés : Autism Emotion recognition Facial expressions Index. décimale : PER Périodiques Résumé : Autism is associated with difficulty interacting with others and an impaired ability to recognize facial expressions of emotion. Previous teaching programmes have not addressed weak central coherence. Emotion recognition training focused on components of facial expressions. The training was administered in small groups ranging from 4 to 7 children. Improvements were significantly better for the training group (n = 20, mean age 9 years, 3 months) than a waiting list control group (n = 10, mean age 10 years, 7 months). Pre and post measures revealed an effect size of the training of Cohen’s d = 1.42. The impact of the training was highly significant. There was evidence of some generalisation of the emotion recognition and improvements at follow-up.
