Recognition of Facial Expressions and Prosodic Cues with Graded Emotional Intensities in Adults with Asperger Syndrome / Hirokazu DOI in Journal of Autism and Developmental Disorders, 43-9 (September 2013)

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.

Titre : Toddlers with Williams Syndrome Process Upright but not Inverted Faces Holistically Type de document : Texte imprimé et/ou numérique Auteurs : Cara H. CASHON, Auteur ; Oh-Ryeong HA, Auteur ; Christopher A. DENICOLA, Auteur ; Carolyn B. MERVIS, Auteur Article en page(s) : p.2549-2557 Langues : Anglais (eng) Mots-clés : Face perception Holistic processing Inversion effect Perceptual expertise Williams syndrome Developmental disability Index. décimale : PER Périodiques Résumé : Holistic processing of upright, but not inverted, faces is a marker of perceptual expertise for faces. This pattern is shown by typically developing individuals beginning at age 7 months. Williams syndrome (WS) is a rare neurogenetic developmental disorder characterized by extreme interest in faces from a very young age. Research on the effects of inversion on holistic processing of faces by older children and adults with WS has produced mixed results. Younger children with WS were not included in these previous studies. Using the habituation switch paradigm, we demonstrated that 15–35-month-olds with WS process upright, but not inverted, faces holistically. This study provides evidence of perceptual expertise for faces in individuals with WS early in life.
