The role of children?s neural responses to emotional faces in the intergenerational transmission of anxiety symptomatology / Finola KANE-GRADE in Development and Psychopathology, 37-3 (August 2025)  

Public ISBD [article]  inDevelopment and Psychopathology > 37-3 (August 2025) . - p.1659-1675 Titre : The role of children?s neural responses to emotional faces in the intergenerational transmission of anxiety symptomatology Type de document : texte imprimé Auteurs : Finola KANE-GRADE, Auteur ; Dashiell SACKS, Auteur ; Carter R.

In a prospective longitudinal study of a community sample of N = 464 mother-child dyads, we examined relations among maternal anxiety symptoms when children were infants and age 5 years, child neural responses to emotional faces (angry, fearful, happy) at age 3 years, and child internalizing symptoms at age 5 years. Path analyses tested whether amplitudes of event-related potential (ERP) components selected a priori (N290, Nc, P400) (a) mediated associations between maternal anxiety symptoms in infancy and child internalizing symptoms at 5 years and/or (b) moderated associations between maternal anxiety symptoms at 5 years and child internalizing symptoms at 5 years. Mediating effects were not observed for any of the ERP measures. Nc and P400 amplitudes to angry faces and Nc amplitude to happy faces moderated the effect of maternal anxiety at 5 years on child internalizing symptoms at 5 years. Effects were not related to maternal depressive symptoms. Differential sex effects were not observed. The findings suggest that larger neural responses to emotional faces may represent a biological risk factor that amplifies vulnerability to the development of internalizing symptomatology in young children exposed to maternal anxiety.

Differential electrophysiological responses to biological motion in children and adults with and without autism spectrum disorders / Masahiro HIRAI in Research in Autism Spectrum Disorders, 8-12 (December 2014)  

Public ISBD [article]  inResearch in Autism Spectrum Disorders > 8-12 (December 2014) . - p.1623-1634 Titre : Differential electrophysiological responses to biological motion in children and adults with and without autism spectrum disorders Type de document : texte imprimé Auteurs : Masahiro HIRAI, Auteur ; Atsuko GUNJI, Auteur ; Yuki INOUE, Auteur ; Yosuke KITA, Auteur ; Takashi HAYASHI, Auteur ; Kengo NISHIMAKI, Auteur ; Miho NAKAMURA, Auteur ; Ryusuke KAKIGI, Auteur ; Masumi INAGAKI, Auteur Article en page(s) : p.1623-1634 Langues : Anglais (eng) Mots-clés : Point-light walker  Biological motion  Event-related potential (ERP)  Autism spectrum disorder  Development  Children Index. décimale : PER Périodiques Résumé : Abstract Although atypical processing of biological motion (BM) in individuals with autism spectrum disorder (ASD) has been reported, the temporal profile of the neural response to BM is not well explored. In the current study, event-related potentials (ERPs) were measured in 12 individuals with ASD, aged 8–22 years, and 12 age- and gender-matched normal controls, to investigate the electrophysiological response to BM and a control visual stimulus. By introducing a novel experimental paradigm that can dissociate the electrophysiological responses to motion processing and the global shape processing of BM, we found that: (1) the timing of the response was preserved in ASD groups, whereas (2) the ERP response to BM was significantly enhanced compared with scrambled point-light motion (SM) in normal controls; the responses to both BM and SM were not significantly different in subjects with ASD. Because we did not find a significant group effect on the peak and mean amplitude induced by BM, it is presumed that this atypical response in individuals with ASD was due to over-sensitivity to the local motion signals. This experimental paradigm showed atypical local motion processing of BM in individuals with ASD.
