Early life stress is associated with reduced avoidance of threatening facial expressions / Elizabeth J. KIRKHAM in Development and Psychopathology, 32-3 (August 2020)
[article]
Titre : Early life stress is associated with reduced avoidance of threatening facial expressions Type de document : Texte imprimé et/ou numérique Auteurs : Elizabeth J. KIRKHAM, Auteur ; Liat LEVITA, Auteur Article en page(s) : p.1059-1067 Langues : Anglais (eng) Mots-clés : anger approach avoidance early life stress emotional facial expressions Index. décimale : PER Périodiques Résumé : Early neglect or maltreatment has been associated with changes in children's processing of emotional facial expressions, including a hypersensitivity to the emotion of anger. This may facilitate the avoidance of danger in a maltreating environment. However, few studies have examined whether experiences of early life stress (ELS) are associated with atypical avoidance responses towards emotional facial expressions, or whether the effects of ELS can be observed in adult participants. The present study therefore examined the effects of ELS on adults' approach-avoidance tendencies towards angry, happy, and neutral facial expressions. Surprisingly, higher levels of ELS were associated with reduced avoidance of angry facial expressions among individuals with no evidence of mental illness. In contrast, there was no evidence of a relationship between ELS and avoidance of angry facial expressions among individuals with experience of mental illness. These novel findings suggest that ELS-related changes in social cognition can be observed years after the ELS itself occurred.

Titre : Motion-Capture Patterns of Voluntarily Mimicked Dynamic Facial Expressions in Children and Adolescents With and Without ASD Type de document : Texte imprimé et/ou numérique Auteurs : E. ZANE, Auteur ; Z. YANG, Auteur ; L. POZZAN, Auteur ; T. GUHA, Auteur ; S. NARAYANAN, Auteur ; R. B. GROSSMAN, Auteur Article en page(s) : p.1062-1079 Langues : Anglais (eng) Mots-clés : Asd Emotional facial expressions Motion capture Social communication Index. décimale : PER Périodiques Résumé : Research shows that neurotypical individuals struggle to interpret the emotional facial expressions of people with Autism Spectrum Disorder (ASD). The current study uses motion-capture to objectively quantify differences between the movement patterns of emotional facial expressions of individuals with and without ASD. Participants volitionally mimicked emotional expressions while wearing facial markers. Recorded marker movement was grouped by expression valence and intensity. We used Growth Curve Analysis to test whether movement patterns were predictable by expression type and participant group. Results show significant interactions between expression type and group, and little effect of emotion valence on ASD expressions. Together, results support perceptions that expressions of individuals with ASD are different from-and more ambiguous than-those of neurotypical individuals'.

This was done to detect differences in valence processing between 25 subjects with autism spectrum disorders (ASDs) and 27 typically developing controls. Valence scaling was abnormal in ASDs. Positive valence induces lower deactivation and abnormally strong activity in ASD in multiple regions. Negative valence increased deactivation in visual areas in subjects with ASDs. The most marked differences between valences focus on fronto-insular and temporal regions. This supports the idea that subjects with ASDs may have difficulty in passive processing of the salience and mirroring of expressions. When the valence scaling of brain activity fails, in contrast to controls, these areas activate and/or deactivate inappropriately during facial stimuli presented dynamically.
