Differences in the Late Positive Potential and P300 to Emotional Faces in Individuals with Autism Spectrum Disorder / C. M. KEIFER in Journal of Autism and Developmental Disorders, 49-12 (December 2019)
[article]
Titre : Differences in the Late Positive Potential and P300 to Emotional Faces in Individuals with Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : C. M. KEIFER, Auteur ; K. M. HAUSCHILD, Auteur ; B. D. NELSON, Auteur ; G. HAJCAK, Auteur ; M. D. LERNER, Auteur Article en page(s) : p.5009-5022 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder Erp Emotion processing Lpp P300 Social cognition Index. décimale : PER Périodiques Résumé : Despite evidence suggesting differences in early event-related potential (ERP) responses to social emotional stimuli, little is known about later stage ERP contributions to social emotional processing in individuals with autism spectrum disorder (ASD). Adults with and without ASD completed a facial emotion recognition task involving stimuli that varied by emotional intensity while electroencephalograms were recorded. Principal components analysis was used to examine P300 and late positive potential (LPP) modulation by emotional intensity. Results indicated that greater ASD symptomatology evinced heightened P300 to high relative to low intensity faces, then heightened LPP to low relative to high intensity faces. Findings suggest that adults with greater ASD symptomatology may demonstrate a lag in engagement in elaborative processing of low intensity faces.

Titre : Parenting style moderates the effects of exposure to natural disaster-related stress on the neural development of reactivity to threat and reward in children Type de document : Texte imprimé et/ou numérique Auteurs : E.

KLEIN, Auteur Article en page(s) : p.1589-1598 Langues : Anglais (eng) Mots-clés : brain development event-related potentials natural disaster parenting Index. décimale : PER Périodiques Résumé : Little is known about the effect of natural disasters on children's neural development. Additionally, despite evidence that stress and parenting may both influence the development of neural systems underlying reward and threat processing, few studies have brought together these areas of research. The current investigation examined the effect of parenting styles and hurricane-related stress on the development of neural reactivity to reward and threat in children. Approximately 8 months before and 9 months after Hurricane Sandy, 74 children experiencing high and low levels of hurricane-related stress completed tasks that elicited the reward positivity and error-related negativity, event-related potentials indexing sensitivity to reward and threat, respectively. At the post-Hurricane assessment, children completed a self-report questionnaire to measure promotion- and prevention-focused parenting styles. Among children exposed to high levels of hurricane-related stress, lower levels of promotion-focused, but not prevention-focused, parenting were associated with a reduced post-Sandy reward positivity. In addition, in children with high stress exposure, greater prevention-focused, but not promotion-focused, parenting was associated with a larger error-related negativity after Hurricane Sandy. These findings highlight the need to consider contextual variables such as parenting when examining how exposure to stress alters the development of neural reactivity to reward and threat in children.
