Atypical recognition of dynamic changes in facial expressions in autism spectrum disorders / Wataru SATO in Research in Autism Spectrum Disorders, 7-7 (July 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-7 (July 2013) . - p.906-912 Titre : Atypical recognition of dynamic changes in facial expressions in autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Wataru SATO, Auteur ; Shota UONO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.906-912 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD)  Dynamic facial expressions  Naturalness  Speed Index. décimale : PER Périodiques Résumé : Previous studies have suggested that the processing of dynamic facial expressions is impaired in autism spectrum disorders (ASD). However, the specific component that is impaired in the processing of dynamic facial expressions has not been identified. We investigated the recognition of dynamic changes in facial expressions among individuals with ASD and age- and sex-matched typically developing controls. Morphing animations of facial expressions of six emotions were presented at four different changing speeds, and participants rated the naturalness of the expression changes. The correspondence between reduced speeds and decreased naturalness ratings was weaker in the ASD than in the control group. These results suggest that the atypical visual analysis of dynamic changes in facial expressions underlies the impairment in real-life social interaction among individuals with ASD.

Brief Report: Representational Momentum for Dynamic Facial Expressions in Pervasive Developmental Disorder / Shota UONO in Journal of Autism and Developmental Disorders, 40-3 (March 2010)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 40-3 (March 2010) . - p.371-377 Titre : Brief Report: Representational Momentum for Dynamic Facial Expressions in Pervasive Developmental Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Shota UONO, Auteur ; Motomi TOICHI, Auteur ; Wataru SATO, Auteur Année de publication : 2010 Article en page(s) : p.371-377 Langues : Anglais (eng) Mots-clés : Asperger’s-disorder Dynamic-facial-expression Pervasive-developmental-disorder Representational-momentum Index. décimale : PER Périodiques Résumé : Individuals with pervasive developmental disorder (PDD) have difficulty with social communication via emotional facial expressions, but behavioral studies involving static images have reported inconsistent findings about emotion recognition. We investigated whether dynamic presentation of facial expression would enhance subjective perception of expressed emotion in 13 individuals with PDD and 13 typically developing controls. We presented dynamic and static emotional (fearful and happy) expressions. Participants were asked to match a changeable emotional face display with the last presented image. The results showed that both groups perceived the last image of dynamic facial expression to be more emotionally exaggerated than the static facial expression. This finding suggests that individuals with PDD have an intact perceptual mechanism for processing dynamic information in another individual’s face.

Common and unique impairments in facial-expression recognition in pervasive developmental disorder-not otherwise specified and Asperger's disorder / Shota UONO in Research in Autism Spectrum Disorders, 7-2 (February 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-2 (February 2013) . - p.361-368 Titre : Common and unique impairments in facial-expression recognition in pervasive developmental disorder-not otherwise specified and Asperger's disorder Type de document : Texte imprimé et/ou numérique Auteurs : Shota UONO, Auteur ; Wataru SATO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.361-368 Langues : Anglais (eng) Mots-clés : Asperger's disorder  Facial expression recognition  Pervasive developmental disorder  Pervasive developmental disorder-not otherwise specified Index. décimale : PER Périodiques Résumé : This study was designed to identify specific difficulties and associated features related to the problems with social interaction experienced by individuals with pervasive developmental disorder-not otherwise specified (PDD-NOS) using an emotion-recognition task. We compared individuals with PDD-NOS or Asperger's disorder (ASP) and typically developing individuals in terms of their ability to recognize facial expressions conveying the six basic emotions. Individuals with PDD-NOS and ASP were worse at recognizing fearful faces than were controls. Individuals with PDD-NOS were less accurate in recognizing disgusted faces than were those with ASP. The results suggest that PDD subtypes are characterized by shared and unique impairments in the ability to recognize facial expressions. Furthermore, the ability to recognize fearful but not disgusted expressions was negatively correlated with the severity of social dysfunction in PDD-NOS and ASP. The results suggest that impaired recognition of fearful and disgusted faces may reflect the severity of social dysfunction across PDD subtypes and the specific problems associated with PDD-NOS, respectively. Characteristics associated with different levels of symptom severity in PDD-NOS are discussed in terms of similarities with brain damage and other psychiatric disorders.

Impaired Overt Facial Mimicry in Response to Dynamic Facial Expressions in High-Functioning Autism Spectrum Disorders / Sayaka YOSHIMURA in Journal of Autism and Developmental Disorders, 45-5 (May 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-5 (May 2015) . - p.1318-1328 Titre : Impaired Overt Facial Mimicry in Response to Dynamic Facial Expressions in High-Functioning Autism Spectrum Disorders Type de document : Texte imprimé et/ou numérique Auteurs : Sayaka YOSHIMURA, Auteur ; Wataru SATO, Auteur ; Shota UONO, Auteur ; Motomi TOICHI, Auteur Article en page(s) : p.1318-1328 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders (ASD)  Dynamic facial expression  Facial mimicry  Reciprocal social interaction Index. décimale : PER Périodiques Résumé : Previous electromyographic studies have reported that individuals with autism spectrum disorders (ASD) exhibited atypical patterns of facial muscle activity in response to facial expression stimuli. However, whether such activity is expressed in visible facial mimicry remains unknown. To investigate this issue, we videotaped facial responses in high-functioning individuals with ASD and controls to dynamic and static facial expressions of anger and happiness. Visual coding of facial muscle activity and the subjective impression ratings showed reduced congruent responses to dynamic expressions in the ASD group. Additionally, this decline was related to social dysfunction. These results suggest that impairment in overt facial mimicry in response to others’ dynamic facial expressions may underlie difficulties in reciprocal social interaction among individuals with ASD.

Impairment of unconscious, but not conscious, gaze-triggered attention orienting in Asperger's disorder / Wataru SATO in Research in Autism Spectrum Disorders, 4-4 (October-December 2010)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 4-4 (October-December 2010) . - p.782-786 Titre : Impairment of unconscious, but not conscious, gaze-triggered attention orienting in Asperger's disorder Type de document : Texte imprimé et/ou numérique Auteurs : Wataru SATO, Auteur ; Motomi TOICHI, Auteur ; Shota UONO, Auteur ; Takashi OKADA, Auteur Année de publication : 2010 Article en page(s) : p.782-786 Langues : Anglais (eng) Mots-clés : Attention-orienting Asperger's-disorder Gaze Pervasive-developmental-disorder-(PDD) Unconscious-processing Subliminal-presentation Index. décimale : PER Périodiques Résumé : Impairment of joint attention represents the core clinical features of pervasive developmental disorders (PDDs), including autism and Asperger's disorder. However, experimental studies reported intact gaze-triggered attentional orienting in PDD. Since all previous studies employed supraliminal presentation of gaze stimuli, we hypothesized that individuals with PDD may be impaired not in conscious but in unconscious gaze-triggered attention shift. We tested the hypothesis in a group of Asperger's disorder (N = 12) and age- and gender-matched controls (N = 13), using a cueing paradigm with supraliminal and subliminal presentation of gaze cues. Under supraliminal conditions, the gaze cueing effect was evident in both groups. Under subliminal conditions, the Asperger group, unlike the control group, did not show the gaze cueing effect. These results indicate the impairment of unconscious, but not conscious, joint attention in Asperger's disorder, which may underlie some clinical findings of social malfunction in PDD.
