Inversion effects in the perception of the moving human form: A comparison of adolescents with autism spectrum disorder and typically developing adolescents / Laura CLEARY in Autism, 18-8 (November 2014)

Titre : Inversion effects in the perception of the moving human form: A comparison of adolescents with autism spectrum disorder and typically developing adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Laura CLEARY, Auteur ; Kathy LOONEY, Auteur ; Nuala BRADY, Auteur ; Michael FITZGERALD, Auteur Article en page(s) : p.943-952 Langues : Anglais (eng) Mots-clés : autism spectrum disorders biological motion perception body inversion effect configural processing Index. décimale : PER Périodiques Résumé : The “body inversion effect” refers to superior recognition of upright than inverted images of the human body and indicates typical configural processing. Previous research by Reed et al. using static images of the human body shows that people with autism fail to demonstrate this effect. Using a novel task in which adults, adolescents with autism, and typically developing adolescents judged whether walking stick figures—created from biological motion recordings and shown at seven orientations between 0° and 180°—were normal or distorted, this study shows clear effects of stimulus inversion. Reaction times and “inverse efficiency” increased with orientation for normal but not distorted walkers, and sensitivity declined with rotation from upright for all groups. Notably, the effect of stimulus inversion was equally detrimental to both groups of adolescents suggesting intact configural processing of the body in motion in autism spectrum disorder.

Titre : Recognition of Facial Expressions and Prosodic Cues with Graded Emotional Intensities in Adults with Asperger Syndrome Type de document : Texte imprimé et/ou numérique Auteurs : Hirokazu DOI, Auteur ; Takashi X. FUJISAWA, Auteur ; Chieko KANAI, Auteur ; Haruhisa OHTA, Auteur ; Hideki YOKOI, Auteur ; Akira IWANAMI, Auteur ; Nobumasa KATO, Auteur ; Kazuyuki SHINOHARA, Auteur Article en page(s) : p.2099-2113 Langues : Anglais (eng) Mots-clés : Facial expression Prosody Inversion effect Configural processing Asperger syndrome Index. décimale : PER Périodiques Résumé : This study investigated the ability of adults with Asperger syndrome to recognize emotional categories of facial expressions and emotional prosodies with graded emotional intensities. The individuals with Asperger syndrome showed poorer recognition performance for angry and sad expressions from both facial and vocal information. The group difference in facial expression recognition was prominent for stimuli with low or intermediate emotional intensities. In contrast to this, the individuals with Asperger syndrome exhibited lower recognition accuracy than typically-developed controls mainly for emotional prosody with high emotional intensity. In facial expression recognition, Asperger and control groups showed an inversion effect for all categories. The magnitude of this effect was less in the Asperger group for angry and sad expressions, presumably attributable to reduced recruitment of the configural mode of face processing. The individuals with Asperger syndrome outperformed the control participants in recognizing inverted sad expressions, indicating enhanced processing of local facial information representing sad emotion. These results suggest that the adults with Asperger syndrome rely on modality-specific strategies in emotion recognition from facial expression and prosodic information.

Titre : The development of perceptual expertise for faces and objects in autism spectrum conditions Type de document : Texte imprimé et/ou numérique Auteurs : Cara R. DAMIANO, Auteur ; Owen CHURCHES, Auteur ; Howard RING, Auteur ; Simon BARON-COHEN, Auteur Année de publication : 2011 Article en page(s) : p.297-301 Langues : Anglais (eng) Mots-clés : face processing object processing autism spectrum conditions inversion effect perceptual expertise configural processing local processing Index. décimale : PER Périodiques Résumé : Previous research indicates that individuals with autism spectrum conditions (ASC) do not develop face expertise to the same extent as typical individuals. Yet it remains unclear whether this atypicality is specific to faces or related to more pervasive perceptual or cognitive deficits involved in the actual process of gaining expertise. To address this question, we examined the extent to which adults with ASC were capable of developing expertise with non-face objects. To become experts, all participants completed a 2-week training program with novel objects, known as Greebles. Level of expertise was assessed throughout training by measuring the ability to identify Greebles on an individual level. The perceptual strategies acquired as a result of expertise were measured through an inversion effect task completed before and after training, in which performance with upright Greebles and faces was compared to performance with inverted Greebles and faces. After expertise training, it was found that individuals in both the ASC and the typical group successfully achieved expertise and showed an enhanced Greeble inversion effect as a result of training. The development of an inversion effect with Greebles suggests that individuals with ASC may employ the same processing strategies as the typical group. Although exploratory, these findings have implications for understanding the nature of the face processing deficit in ASC as well as offering potential insights into face processing interventions for individuals with ASC.
