Face processing in children with ASD: Literature review / Giulia CAMPATELLI in Research in Autism Spectrum Disorders, 7-3 (March 2013)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 7-3 (March 2013) . - p.444-454 Titre : Face processing in children with ASD: Literature review Type de document : Texte imprimé et/ou numérique Auteurs : Giulia CAMPATELLI, Auteur ; R. R. FEDERICO, Auteur ; Fabio APICELLA, Auteur ; F. SICCA, Auteur ; Filippo MURATORI, Auteur Article en page(s) : p.444-454 Mots-clés : Autism  Face processing  ERPs  fMRI Index. décimale : PER Périodiques Résumé : Face processing has been studied and discussed in depth during previous decades in several branches of science, and evidence from research supports the view that this process is a highly specialized brain function. Several authors argue that difficulties in the use and comprehension of the information conveyed by human faces could represent a core deficit in autism. Neuroimaging and ERP studies show that the brains of individuals with autism spectrum disorders (ASD) fail to activate and coordinate the activation of the cortical regions that are specialized in face processing. However, the mechanisms for the occurrence of this impairment remain poorly understood. ERP studies that investigate brain activity in ASD individuals during face processing have yielded mixed results. This review reports several debates in the literature regarding the interpretation of recorded neural components, their correlation with ASD, the possible organization of neural networks, the strategies of encoding structural and emotional stimuli, and the future goals of research.

Face processing abilities in relatives of individuals with ASD / Simon WALLACE in Autism Research, 3-6 (December 2010)  

Public ISBD [article]  inAutism Research > 3-6 (December 2010) . - p.345-349 Titre : Face processing abilities in relatives of individuals with ASD Type de document : Texte imprimé et/ou numérique Auteurs : Simon WALLACE, Auteur ; Catherine L. SEBASTIAN, Auteur ; Elizabeth PELLICANO, Auteur ; Jeremy R. PARR, Auteur ; Anthony J. BAILEY, Auteur Année de publication : 2010 Article en page(s) : p.345-349 Langues : Anglais (eng) Mots-clés : autism spectrum disorder  broader autism phenotype  relatives  genetics  face processing Index. décimale : PER Périodiques Résumé : Individuals with an autism spectrum disorder (ASD) show difficulties identifying familiar faces, recognizing emotional expressions and judging eye-gaze direction. Recent research suggests that relatives of individuals with AS also show impairments in some aspects of face processing but no study has comprehensively assessed the nature and extent of face-processing difficulties in a group of relatives. This study compared the performance of 22 parents/adult siblings of individuals with ASD (“relatives” group), 26 adults with ASD, and 26 typically developing adults on tasks of face discrimination, facial expression recognition and judging eye-gaze direction. Relatives of individuals with ASD were less able to discriminate subtle differences between faces than typically developing adults, but were more sensitive to such differences than adults with ASD. Furthermore, relatives were significantly worse at identifying expressions of fear and disgust than typically developing adults and failed to show the typical sensitivity to direct compared with averted eye-gaze direction—a strikingly similar pattern to that observed in adults with ASD. These findings show that atypical patterns of face processing are found in some relatives of individuals with ASD and suggest that these difficulties may represent a cognitive endophenotype.

Face Processing in Children with Autism Spectrum Disorder: Independent or Interactive Processing of Facial Identity and Facial Expression? / Julia F. KREBS in Journal of Autism and Developmental Disorders, 41-6 (June 2011)

Children with autism and IQ and age matched typically developing children classified faces either by emotional expression, thereby ignoring facial identity or by facial identity disregarding emotional expression. Typically developing children processed facial identity independently from facial expressions but processed facial expressions in interaction with identity. Children with autism processed both facial expression and identity independently of each other. They selectively directed their attention to one facial parameter despite variations in the other. Results indicate that there is no interaction in processing facial identity and emotional expression in autism spectrum disorder.

Autistic and non-autistic individuals show the same amygdala activity during emotional face processing / Benedikt P LANGENBACH in Molecular Autism, 15 (2024)  

Public ISBD [article]  inMolecular Autism > 15 (2024) . - 2p. Titre : Autistic and non-autistic individuals show the same amygdala activity during emotional face processing Type de document : Texte imprimé et/ou numérique Auteurs : Benedikt P LANGENBACH, Auteur ; Dominik GROTEGERD, Auteur ; Peter C R MULDERS, Auteur ; Indira TENDOLKAR, Auteur ; Jasper VAN OORT, Auteur ; Fleur DUYSER, Auteur ; Philip VAN EIJNDHOVEN, Auteur ; Janna N VRIJSEN, Auteur ; Udo DANNLOWSKI, Auteur ; Zarah KAMPMANN, Auteur ; Katja KOELKEBECK, Auteur Article en page(s) : 2p. Langues : Anglais (eng) Mots-clés : Humans  Autistic Disorder  Autism Spectrum Disorder  Facial Recognition  Emotions  Amygdala/diagnostic imaging  Amygdala  Autism  Emotion processing  Face processing  fMRI Index. décimale : PER Périodiques Résumé : BACKGROUND: Autistic and non-autistic individuals often differ in how they perceive and show emotions, especially in their ability and inclination to infer other people's feelings from subtle cues like facial expressions. Prominent theories of autism have suggested that these differences stem from alterations in amygdala functioning and that amygdala hypoactivation causes problems with emotion recognition. Thus far, however, empirical investigations of this hypothesis have yielded mixed results and largely relied on relatively small samples. METHODS: In a sample of 72 autistic and 79 non-autistic participants, we conducted a study in which we used the Hariri paradigm to test whether amygdala activation during emotional face processing is altered in autism spectrum disorder, and whether common mental disorders like depression, ADHD or anxiety disorders influence any potential alterations in activation patterns. RESULTS: We found no evidence for differences in amygdala activation, neither when comparing autistic and non-autistic participants, nor when taking into account mental disorders or the overall level of functional impairment. LIMITATIONS: Because we used one basic emotion processing task in a Dutch sample, results might not generalise to other tasks and other populations. CONCLUSIONS: Our results challenge the view that autistic and non-autistic processing of emotional faces in the amygdala is vastly different and call for a more nuanced view of differences between non-autistic and autistic emotion processing.

Autistic Symptomatology, Face Processing Abilities, and Eye Fixation Patterns / Jennifer C. KIRCHNER in Journal of Autism and Developmental Disorders, 41-2 (February 2011)

Its relevance as a pathophysiological mechanism, however, remains unknown. In the present study, we compared eye fixations of 20 adults with autism and 21 controls while they were engaged in taking the Multifaceted Empathy Test (MET). Additional measures of face emotion and identity recognition were also obtained. While both groups fixated more on the face and mouth in the emotion recognition than in the face identity condition of the MET, individuals with autism fixated less on the face across MET conditions. Correlation analysis revealed associations between fixation time on the eyes and face processing abilities. Our results suggest that eye fixation patterns are an important characteristic of the social phenotype of autism.
