However, the conditions under which these atypicalities arise and their link with behavioral emotional expressions and core ASD symptoms remain uncertain. Given the importance of physiological arousal in affective, learning, and cognitive processes, the current study examined changes in skin conductance level (ΔSCL) in 41 toddlers with ASD (mean age: 22.7 months, SD: 2.9) and 32 age-matched toddlers with typical development (TD) (mean age: 21.6 months, SD: 3.6) in response to probes designed to induce anger, joy, and fear emotions. The magnitude of ΔSCL was comparable during anger (P = 0.206, d = 0.30) and joy (P = 0.996, d = 0.01) conditions, but significantly lower during the fear condition (P = 0.001, d = 0.83) in toddlers with ASD compared to TD peers. In the combined samples, ΔSCL positively correlated with intensity of behavioral emotional expressivity during the anger (r[71] = 0.36, P = 0.002) and fear (r[68] = 0.32, P = 0.007) conditions, but not in the joy (r[69] = −0.15, P = 0.226) condition. Finally, ΔSCL did not associate with autism symptom severity in any emotion-eliciting condition in the ASD group. Toddlers with ASD displayed attenuated ΔSCL to situations aimed at eliciting fear, which may forecast the emergence of highly prevalent internalizing and externalizing problems in this population. The study putatively identifies ΔSCL as a dimension not associated with severity of autism but with behavioral responses in negatively emotionally challenging events and provides support for the feasibility, validity, and incipient utility of examining ΔSCL in response to emotional challenges in very young children. Lay Summary Physiological arousal was measured in toddlers with autism exposed to frustrating, pleasant, and threatening tasks. Compared to typically developing peers, toddlers with autism showed comparable arousal responses to frustrating and pleasant events, but lower responses to threatening events. Importantly, physiological arousal and behavioral expressions were aligned during frustrating and threatening events, inviting exploration of physiological arousal to measure responses to emotional challenges. Furthermore, this study advances the understanding of precursors to emotional and behavioral problems common in older children with autism.

Infants' neural responses to emotional faces are related to maternal anxiety / Lindsay C. BOWMAN in Journal of Child Psychology and Psychiatry, 63-2 (February 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-2 (February 2022) . - p.152-164 Titre : Infants' neural responses to emotional faces are related to maternal anxiety Type de document : texte imprimé Auteurs : Lindsay C. BOWMAN, Auteur ; Sarah A. MCCORMICK, Auteur ; Finola KANE-GRADE, Auteur ; Weiguo XIE, Auteur ; Michelle BOSQUET ENLOW, Auteur ; Charles A. NELSON, Auteur Article en page(s) : p.152-164 Langues : Anglais (eng) Mots-clés : Eeg/erp  Maternal anxiety  N290  Nc  P400  emotions  faces  infants Index. décimale : PER Périodiques Résumé : BACKGROUND: Postnatal maternal anxiety is common (estimates as high as 40% prevalence) and is associated with altered mother-infant interactions (e.g., reduced maternal emotional expression and engagement). Neural circuitry supporting infants' face and emotion processing develops in their first year. Thus, early exposure to maternal anxiety may impact infants' developing understanding of emotional displays. We examine whether maternal anxiety is associated with individual differences in typically developing infants' neural responses to emotional faces. METHODS: One hundred and forty two mother-infant dyads were assessed when infants were 5, 7, or 12 months old. Infants' electroencephalographic (EEG) data were recorded while passively viewing female happy, fearful, and angry faces. Three event-related potential (ERP) components, each linked to face and emotion processing, were evaluated: NC, N290, and P400. Infant ERP amplitude was related to concurrent maternal-report anxiety assessed with the Spielberger State-Trait Anxiety Inventory (Trait form). RESULTS: Greater maternal anxiety predicted more negative NC amplitude for happy and fearful faces in left and mid-central scalp regions, beyond covarying influences of maternal depression symptoms, infant negative emotionality, and infant age. CONCLUSIONS: Postnatal maternal anxiety is related to infants' neural processing of emotional expressions. Infants of mothers endorsing high trait anxiety may need additional attentional resources to process happy and fearful faces (expressions less likely experienced in mother-infant interactions). Future research should investigate mechanisms underlying this association, given possibilities include experiential, genetic, and prenatal factors.

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)

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.
