Neural correlates of emotion processing during observed self-face recognition in individuals with autism spectrum disorders / Tomoyo MORITA in Research in Autism Spectrum Disorders, 26 (June 2016)
[article]
Titre : Neural correlates of emotion processing during observed self-face recognition in individuals with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : Tomoyo MORITA, Auteur ; Hirotaka KOSAKA, Auteur ; Daisuke N. SAITO, Auteur ; Takeshi FUJII, Auteur ; Makoto ISHITOBI, Auteur ; Toshio MUNESUE, Auteur ; Keisuke INOHARA, Auteur ; Hidehiko OKAZAWA, Auteur ; Ryusuke KAKIGI, Auteur ; Norihiro SADATO, Auteur Article en page(s) : p.16-32 Langues : Anglais (eng) Mots-clés : Anterior cingulate cortex Anterior insula Autism spectrum disorder (ASD) Being observed Embarrassment Functional magnetic resonance imaging Self-face Index. décimale : PER Périodiques Résumé : When exposed to self-face images, individuals often experience embarrassment, which is enhanced by being observed. This self-evaluative emotion is related to activity in the right anterior insula and the functional connectivity between the anterior cingulate and prefrontal cortices. Coupling between cognitive evaluation of self-face images and emotional response to them (cognitive–emotional coupling) is weaker in individuals with autism spectrum disorder (ASD), in parallel with reduced activity of the right insula. To determine whether self-evaluative emotions of individuals with ASD are less strongly impacted by observation, we conducted functional MRI in 14 adult men with ASD and 18 age-matched control men while the participants viewed self-face images. Increased embarrassment upon observation was positively correlated with increased activity in the right anterior insula in the control group, but not in the ASD group. In addition, awareness of being observed enhanced cognitive–emotional coupling in the controls but not in the ASD group. The coupling was correlated with the functional connectivity between the anterior cingulate and medial prefrontal cortices. These results suggest that the reduced impact of observation on embarrassment induced by self-face images in individuals with ASD is related to impairment in the right anterior insula, which is involved in creating subjective feelings, and the anterior cingulate cortex, which acts as a hub for integrating information from others during self-face evaluation.

Titre : Impaired attentional bias toward one's own face in autism spectrum disorder: ERP evidence Type de document : Texte imprimé et/ou numérique Auteurs : H. B. CYGAN, Auteur ; M. M. NOWICKA, Auteur ; A. NOWICKA, Auteur Article en page(s) : p.241-253 Langues : Anglais (eng) Mots-clés : Erp attention autism self-face Index. décimale : PER Périodiques Résumé : Converging lines of evidence seem to indicate reduced self-referential processing in individuals with autism spectrum disorder (ASD). However, processing of one's own face has rarely been investigated in the context of ASD. Thus, the aim of the present study was to elucidate the role of attentional biases in the processing of self- and other faces in ASD. To achieve this goal we presented participants with images of their own face, the face of a close-other, and famous and unknown faces in a Stroop-like paradigm. Participants (22 with ASD, 22 typically developing [TD]) were instructed to indicate the color of presented faces while EEG was recorded. Our event-related potential results clearly showed that self-face was associated with larger P3 amplitudes than all other faces in the TD group, thus indicating a strong attentional bias toward one's own face. In the ASD group, P3 to the self-face and the close-other's face did not differ, suggesting similar attentional biases in both cases. In line with these P3 findings, nonparametric cluster-based permutation tests showed an analogous pattern of results: significant clusters for the self-face compared with all other faces in the TD group, and no significant cluster in the ASD group. Overall, our findings revealed impaired attentional bias to one's own face and diminished self versus other differentiation in individuals with ASD. The similar neural underpinnings of the self-face and other faces supports previous findings indicating reduced self-prioritization among individuals with ASD.
