Visual search for basic emotional expressions in autism; impaired processing of anger, fear and sadness, but a typical happy face advantage / Emily K. FARRAN in Research in Autism Spectrum Disorders, 5-1 (January-March 2011)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 5-1 (January-March 2011) . - p.455-462 Titre : Visual search for basic emotional expressions in autism; impaired processing of anger, fear and sadness, but a typical happy face advantage Type de document : Texte imprimé et/ou numérique Auteurs : Emily K. FARRAN, Auteur ; Amanda BRANSON, Auteur ; Ben J. KING, Auteur Année de publication : 2011 Article en page(s) : p.455-462 Langues : Anglais (eng) Mots-clés : Autism Emotion Visual-search Face-processing Index. décimale : PER Périodiques Résumé : Facial expression recognition was investigated in 20 males with high functioning autism (HFA) or Asperger syndrome (AS), compared to typically developing individuals matched for chronological age (TD CA group) and verbal and non-verbal ability (TD V/NV group). This was the first study to employ a visual search, “face in the crowd” paradigm with a HFA/AS group, which explored responses to numerous facial expressions using real-face stimuli. Results showed slower response times for processing fear, anger and sad expressions in the HFA/AS group, relative to the TD CA group, but not the TD V/NV group. Reponses to happy, disgust and surprise expressions showed no group differences. Results are discussed with reference to the amygdala theory of autism.
