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)

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.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02522.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=166

Titre : Attentional biases to faces with direct versus averted gaze in children without and with autism spectrum disorder: A dot-probe paradigm Type de document : Texte imprimé et/ou numérique Auteurs : Wei JING, Auteur ; Jing WANG, Auteur ; Jinxia FU, Auteur Article en page(s) : p.102233 Mots-clés : Children with ASD Dot-probe paradigms Direct gaze Averted gaze Facial attention Index. décimale : PER Périodiques Résumé : Previous research utilized a variety of paradigms to demonstrate attentional biases to faces with direct versus averted gaze in typical development (TD) and no such bias in autism spectrum disorder (ASD). However, little is known about whether the biases can be observed during automatic processing stages in TD and whether the lack of such bias in ASD is due to passive neglect or active avoidance of direct gaze. Therefore, we employed a dot-probe paradigm and manipulated stimulus onset asynchrony (SOA) to measure response times to probes replacing faces with direct gaze compared to faces with averted gaze in children without and with ASD. There was no evidence of attentional bias in either group when stimuli were presented during the automatic processing stage (200 ms SOA). However, during the controlled processing stage (1000 ms SOA), an attentional bias to faces with direct versus averted gaze was found in control children but not in those with ASD. The results indicate that the facilitation of direct gaze on facial attention occurs during controlled rather than automatic processing stages in TD individuals. In contrast, children with ASD respond indiscriminately to direct and averted gaze during both stages of cognitive processing, supporting the gaze indifference hypothesis. For TD children but not for children with ASD, direct gaze is an adaptively informative or socially salient signal.

Fifteen adolescents and adults with autism and 14 typically developing comparison participants viewed dynamic virtual-reality videos depicting a simple but realistic social scenario, in which an approaching male figure maintained either direct or averted gaze. Significant group by condition interactions reflecting differential responses to direct versus averted gaze in people with autism relative to typically developing individuals were identified in the right temporoparietal junction, right anterior insula, left lateral occipital cortex, and left dorsolateral prefrontal cortex. Our results provide initial evidence regarding brain mechanisms underlying the processing of gaze direction during simple social encounters, providing new insight into the social deficits in individuals with autism.

Adults viewed videos of actors whose gaze was either directed towards or averted from them. Individuals with lower scores on four subscales of the Autism-Spectrum Quotient (AQ) scale showed a greater tendency to look at directed relative to averted eyes; individuals with higher scores on the AQ did not. This relationship was specific to autism-associated traits and to gaze towards the eyes; it did not generalize to a social anxiety measure or to gaze towards the mouth. We discuss implications for our understanding of the broader autism phenotype.

Titre : Altered sensitivity to social gaze in the FMR1 premutation and pragmatic language competence Type de document : Texte imprimé et/ou numérique Auteurs : J. KLUSEK, Auteur ; J. SCHMIDT, Auteur ; A. J. FAIRCHILD, Auteur ; A. PORTER, Auteur ; J. E. ROBERTS, Auteur Article en page(s) : p.31 Langues : Anglais (eng) Mots-clés : Direct gaze Eye contact Fragile X carriers Social cognition Social communication Index. décimale : PER Périodiques Résumé : BACKGROUND: The FMR1 premutation affects 1:291 women and is associated with a range of cognitive, affective, and physical health complications, including deficits in pragmatic language (i.e., social language). This study investigated attention to eye gaze as a fundamental social-cognitive skill that may be impaired in the FMR1 premutation and could underlie pragmatic deficits. Given the high prevalence of the FMR1 premutation, efforts to define its phenotype and mechanistic underpinnings have significant public health implications. METHODS: Thirty-five women with the FMR1 premutation and 20 control women completed an eye-tracking paradigm that recorded time spent dwelling within the eye region in response to a face displaying either direct or averted gaze. Pragmatic language ability was coded from a conversational sample using the Pragmatic Rating Scale. RESULTS: Women with the FMR1 premutation failed to show attentional preference to direct gaze and spent more time dwelling on the averted eyes relative to controls. While dwelling on the eyes was associated with better pragmatic language performance in controls, these variables were unrelated in the women with the FMR1 premutation. CONCLUSIONS: Altered sensitivity to social gaze, characterized by increased salience of averted gaze, was observed among women with the FMR1 premutation. Furthermore, women with the FMR1 premutation were unable to capitalize on information conveyed through the eyes to enhance social-communicative engagement, which differed from patterns seen in controls. These findings contribute to the growing characterization of social and communication phenotypes associated with the FMR1 premutation.
