Affective–motivational brain responses to direct gaze in children with autism spectrum disorder / Anneli KYLLIAINEN in Journal of Child Psychology and Psychiatry, 53-7 (July 2012)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 53-7 (July 2012) . - p.790-797 Titre : Affective–motivational brain responses to direct gaze in children with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Anneli KYLLIAINEN, Auteur ; Simon WALLACE, Auteur ; Marc N. COUTANCHE, Auteur ; Jukka M. LEPPANEN, Auteur ; James CUSACK, Auteur ; Anthony J. BAILEY, Auteur ; Jari K. HIETANEN, Auteur Année de publication : 2012 Article en page(s) : p.790-797 Langues : Anglais (eng) Mots-clés : Direct gaze  eye contact  autism spectrum disorders  frontal EEG asymmetry  skin conductance Index. décimale : PER Périodiques Résumé : Background:  It is unclear why children with autism spectrum disorders (ASD) tend to be inattentive to, or even avoid eye contact. The goal of this study was to investigate affective–motivational brain responses to direct gaze in children with ASD. To this end, we combined two measurements: skin conductance responses (SCR), a robust arousal measure, and asymmetry in frontal electroencephalography (EEG) activity which is associated with motivational approach and avoidance tendencies. We also explored whether degree of eye openness and face familiarity modulated these responses. Methods:  Skin conductance responses and frontal EEG activity were recorded from 14 children with ASD and 15 typically developing children whilst they looked at familiar and unfamiliar faces with eyes shut, normally open or wide-open. Stimuli were presented in such a way that they appeared to be looming towards the children. Results:  In typically developing children, there were no significant differences in SCRs between the different eye conditions, whereas in the ASD group the SCRs were attenuated to faces with closed eyes and increased as a function of the degree of eye openness. In both groups, familiar faces elicited marginally greater SCRs than unfamiliar faces. In typically developing children, normally open eyes elicited greater relative left-sided frontal EEG activity (associated with motivational approach) than shut eyes and wide-open eyes. In the ASD group, there were no significant differences between the gaze conditions in frontal EEG activity. Conclusions:  Collectively, the results replicate previous finding in showing atypical modulation of arousal in response to direct gaze in children with ASD but do not support the assumption that this response is associated with an avoidant motivational tendency. Instead, children with ASD may lack normative approach-related motivational response to eye contact.

Age-Related Differences in Response to Music-Evoked Emotion Among Children and Adolescents with Autism Spectrum Disorders / K. G. STEPHENSON in Journal of Autism and Developmental Disorders, 46-4 (April 2016)

This study extends and expands the few previous studies of response to music in ASD, measuring both psychophysiological and behavioral responses in younger children (ages 8–11) as well as older adolescents (ages 16–18). Compared to controls, the ASD group demonstrated reduced skin conductance response to music-evoked emotion. Younger groups, regardless of diagnosis, showed greater physiological reactivity to scary stimuli than to other emotions. There was a significant interaction of age group and diagnostic group in identifying scary music stimuli, possibly evidencing disrupted developmental trajectories in ASD for integrating physiological and cognitive cues that may underlie symptoms of anxiety.

Arousal was measured through skin conductance responses (SCR) while the participants (15 children with ASD and 16 control children) viewed a live face of another person. Impairments in social skills was assessed with the Developmental, Dimensional and Diagnostic Interview. The level of arousal enhancement to direct gaze in comparison to arousal to faces with averted gaze or closed eyes was positively associated with impairments in social skills (use of language and other social communication skills and use of gesture and non-verbal play) among children with ASD. There was no similar association among children without ASD. The role of arousal-related factors in influencing eye contact behaviour in ASD is discussed.

Enhanced social learning of threat in adults with autism / Lisa ESPINOSA in Molecular Autism, 11 (2020)  

Public ISBD [article]  inMolecular Autism > 11 (2020) . - 71 p. 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.

A process model linking physiological arousal and fear recognition to aggression via guilt in middle childhood / Tyler COLASANTE in Development and Psychopathology, 33-1 (February 2021)  

Public ISBD [article]  inDevelopment and Psychopathology > 33-1 (February 2021) . - p.109-121 Titre : A process model linking physiological arousal and fear recognition to aggression via guilt in middle childhood Type de document : Texte imprimé et/ou numérique Auteurs : Tyler COLASANTE, Auteur ; Marc JAMBON, Auteur ; Xiaoqing GAO, Auteur ; Tina MALTI, Auteur Article en page(s) : p.109-121 Langues : Anglais (eng) Mots-clés : aggression  childhood  fear recognition  guilt  respiratory sinus arrhythmia  skin conductance Index. décimale : PER Périodiques Résumé : Aggression coincides with emotional underarousal in childhood, but we still lack an understanding of how underarousal contributes to aggression. With an ethnically diverse sample of 8-year-olds (N = 150), we tested whether physiological underarousal and lower fear recognition were indirectly associated with heightened aggression through dampened guilt feelings. Caregivers rated children's aggressive behavior. We assessed children's skin conductance (SC) and respiratory sinus arrhythmia (RSA) while they imagined transgressing norms and measured their fear recognition with a facial morph task. Children reported guilt or lack thereof after hypothetically transgressing. The interaction of decreasing SC and increasing RSA (i.e., physiological underarousal) and poor fear recognition were indirectly associated with higher aggression through their associations with lower guilt. Emotional underarousal may contribute to aggression by disrupting the normative development of guilt. We discuss strategies to improve social-emotional acuity and reduce aggression in children with blunted physiological arousal and fear recognition.
