Effects of eye gaze directions of facial images on looking behaviour and autonomic responses in adolescents with autism spectrum disorders / A. LOUWERSE in Research in Autism Spectrum Disorders, 7-9 (September 2013)
[article]
Titre : Effects of eye gaze directions of facial images on looking behaviour and autonomic responses in adolescents with autism spectrum disorders Type de document : Texte imprimé et/ou numérique Auteurs : A. LOUWERSE, Auteur ; J. N. VAN DER GEEST, Auteur ; J. H. M. TULEN, Auteur ; J. VAN DER ENDE, Auteur ; A. R. VAN GOOL, Auteur ; F. C. VERHULST, Auteur ; Kirstin GREAVES-LORD, Auteur Article en page(s) : p.1043-1053 Langues : Anglais (eng) Mots-clés : Autism spectrum disorders Eyes Gaze direction Eye-tracking Heart rate Skin conductance response Index. décimale : PER Périodiques Résumé : Abstract It has been suggested that atypical eye contact of individuals with autism spectrum disorders (ASDs) arises from an unusually high level of autonomic activity elicited by another person's gaze. The present study investigated visual fixation duration and autonomic reactivity (heart rate, skin conductance response) simultaneously, while adolescents looked towards photographs of neutral faces, with either direct eye gaze, averted eye gaze or closed eyes. Both cognitively able adolescents with ASD (n = 31, mean age = 16 years, mean IQ = 104) and typically developing (TD) adolescents (n = 34, mean age = 16 years, mean IQ = 108) looked significantly longer towards the eye region of faces with direct eye gaze compared with faces with averted eye gaze or closed eyes. The adolescents with ASD did not show higher levels of autonomic activity than TD adolescents while they were instructed to look at the eye region. This suggests that looking at the eye region of static faces does not particularly trigger high autonomic arousal in adolescents with ASD.

Titre : Psychophysiological and Behavioral Responses to a Novel Intruder Threat Task for Children on the Autism Spectrum Type de document : Texte imprimé et/ou numérique Auteurs : M. SOUTH, Auteur ; K. M. TAYLOR, Auteur ; T. NEWTON, Auteur ; M. CHRISTENSEN, Auteur ; N. K. JAMISON, Auteur ; P. CHAMBERLAIN, Auteur ; O. JOHNSTON, Auteur ; M. J. CROWLEY, Auteur ; J. D. HIGLEY, Auteur Année de publication : 2017 Article en page(s) : p.3704-3713 Langues : Anglais (eng) Mots-clés : Anxiety Autism spectrum disorders Skin conductance response Social threat Index. décimale : PER Périodiques Résumé : We measured skin conductance response (SCR) to escalating levels of a direct social threat from a novel, ecologically-relevant experimental paradigm, the Intruder Threat Task. We simultaneously evaluated the contribution of social symptom severity and behavioral movement. Children with AS group showed less psychophysiological reactivity to social threat than controls across all three phases of the experiment. In the AS group, greater social impairment was significantly associated with reduced SCR. However, movement activity predicted SCR while diagnosis did not. Research and treatment need to account for the complex interplay of emotional reactivity and social behavior in AS. Psychophysiology studies of AS should consider the impact of possible confounds such as movement.
