Autistic Children Quickly Orient Away from Both Eyes and Mouths During Face Observation / Lilja Kristin JONSDOTTIR in Journal of Autism and Developmental Disorders, 53-1 (January 2023)
[article]
Titre : Autistic Children Quickly Orient Away from Both Eyes and Mouths During Face Observation Type de document : Texte imprimé et/ou numérique Auteurs : Lilja Kristin JONSDOTTIR, Auteur ; Janina NEUFELD, Auteur ; Terje FALCK-YTTER, Auteur ; Johan LUNDIN KLEBERG, Auteur Article en page(s) : p.495-502 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Studies have supported two different hypotheses of reduced eye gaze in people with ASD; gaze avoidance and gaze indifference, while less is known about the role of anxiety. We tested these hypotheses using an eye-tracking paradigm that cued the eyes or mouth of emotional faces. Autistic children (n=12, mean age 7 years) looked faster away from both eyes and mouths than controls (n=22). This effect was not explained by anxiety symptoms. No difference was found in latency towards either area. These results indicate that attentional avoidance of autistic children is not specific to eyes, and that they do not show attentional indifference to eyes compared to controls. Atypicalities in visual scanning in ASD are possibly unrelated to specific facial areas.

Titre : Enhanced social learning of threat in adults with autism Type de document : Texte imprimé et/ou numérique Auteurs : Lisa ESPINOSA, Auteur ; Johan LUNDIN KLEBERG, Auteur ; Björn HOFVANDER, Auteur ; Steve BERGGREN, Auteur ; Sven BÖLTE, Auteur ; Andreas OLSSON, Auteur Article en page(s) : 71 p. Langues : Anglais (eng) Mots-clés : Anxiety Attention Autism Eye tracking Skin conductance Social cognition Social fear learning Vicarious threat Index. décimale : PER Périodiques Résumé : BACKGROUND: Recent theories have linked autism to challenges in prediction learning and social cognition. It is unknown, however, how autism affects learning about threats from others "demonstrators" through observation, which contains predictive learning based on social information. The aims of this study are therefore to investigate social fear learning in individual with autism spectrum disorder (ASD) and to examine whether typically developing social cognition is necessary for successful observational learning. METHODS: Adults with ASD (n = 23) and neurotypical controls (n = 25) completed a social fear learning (SFL) procedure in which participants watched a "demonstrator" receiving electrical shocks in conjunction with a previously neutral conditioned stimulus (CS+), but never with a safe control stimulus (CS-). Skin conductance was used to measure autonomic responses of learned threat responses to the CS+ versus CS-. Visual attention was measured during learning using eye tracking. To establish a non-social learning baseline, each participant also underwent a test of Pavlovian conditioning. RESULTS: During learning, individuals with ASD attended less to the demonstrator's face, and when later tested, displayed stronger observational, but not Pavlovian, autonomic indices of learning (skin conductance) compared to controls. In controls, both higher levels of attention to the demonstrator's face and trait empathy predicted diminished expressions of learning during test. LIMITATIONS: The relatively small sample size of this study and the typical IQ range of the ASD group limit the generalizability of our findings to individuals with ASD in the average intellectual ability range. CONCLUSIONS: The enhanced social threat learning in individuals with ASD may be linked to difficulties using visual attention and mental state attributions to downregulate their emotion.

Titre : Visual orienting in children with autism: Hyper-responsiveness to human eyes presented after a brief alerting audio-signal, but hyporesponsiveness to eyes presented without sound Type de document : Texte imprimé et/ou numérique Auteurs : Johan LUNDIN KLEBERG, Auteur ; Emilia THORUP, Auteur ; Terje FALCK-YTTER, Auteur Article en page(s) : p.246-250 Langues : Anglais (eng) Mots-clés : Autism social orienting eye tracking phasic alerting arousal face perception Index. décimale : PER Périodiques Résumé : Autism Spectrum Disorder (ASD) has been associated with reduced orienting to social stimuli such as eyes, but the results are inconsistent. It is not known whether atypicalities in phasic alerting could play a role in putative altered social orienting in ASD. Here, we show that in unisensory (visual) trials, children with ASD are slower to orient to eyes (among distractors) than controls matched for age, sex, and nonverbal IQ. However, in another condition where a brief spatially nonpredictive sound was presented just before the visual targets, this group effect was reversed. Our results indicate that orienting to social versus nonsocial stimuli is differently modulated by phasic alerting mechanisms in young children with ASD.
