Motivational approach and avoidance in autism spectrum disorder: A comparison between real photographs and cartoons / Catarina SILVA in Research in Autism Spectrum Disorders, 17 (September 2015)
[article]
Titre : Motivational approach and avoidance in autism spectrum disorder: A comparison between real photographs and cartoons Type de document : Texte imprimé et/ou numérique Auteurs : Catarina SILVA, Auteur ; David DA FONSECA, Auteur ; Francisco ESTEVES, Auteur ; Christine DERUELLE, Auteur Année de publication : 2015 Article en page(s) : p.13-24 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Approach Avoidance Social motivation Emotion Cartoons Index. décimale : PER Périodiques Résumé : Abstract Individuals with autism spectrum disorder (ASD) show a lack of motivation to engage in spontaneous social encounters with other human beings. However, the basis for these diminished approach-related social behaviours is still unclear. This study investigated social motivation in ASD using an approach-avoidance task. In particular, we presented a group of ASD and a group of neurotypical adolescents with a series of emotionally positive, negative, and neutral visual stimuli, comprised of real photographs and cartoons – a stimulus with incentive salience for individuals with ASD. Participants were asked to either push or pull a joystick in response to an emotionally independent feature of the stimuli (colour frame). Following the main task, participants also rated the stimuli for affective valence and arousal. Results showed a dissociation in motivational responses towards positive stimuli for the ASD group only: faster avoidance from positive real photographs, but greater approach to positive cartoons, while no differences were found between emotionally negative or neutral stimuli. By contrast, no differences between the groups were found for the self-reported affective ratings. In light of the social motivation hypothesis, these atypical motivational responses suggest a deficit in assigning reward to socio-emotional stimuli in adolescents with ASD.

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.
