Dyadic RSA concordance as a neurobiological marker of sensitivity to parenting behaviors among behaviorally inhibited children / Nila SHAKIBA in Development and Psychopathology, 37-5 (December 2025)

Recent work, however, suggests that the parent-child dyadic RSA concordance may also provide important insight into heterogeneity in the links between parenting behaviors and children’s adjustment outcomes. This study is among the first to characterize dyadic patterns of RSA concordance between behaviorally inhibited children aged 3.5 to 5 years old (54% female, 47% White) and their caregivers (n = 107 dyads) across tasks designed to mimic children’s exposure to novel social interactions while parents observed their children navigating these tasks. Furthermore, we examined dyadic RSA concordance as a potential moderator of the associations between nurturing and intrusive parenting behaviors and children’s adjustment problems, as reported by teachers and parents. We found that a more positive concordance (i.e., caregivers and children demonstrated similar patterns of epoch-to-epoch RSA change across tasks) protected against teacher-reported internalizing problems in the context of low parental nurturance. A negative concordance (i.e., caregivers and children demonstrated dissimilar patterns of epoch-to-epoch RSA change across tasks), however, exacerbated the risk for parents' reports of children’s externalizing behaviors in the context of high parental intrusion.

Longitudinal associations between the infant gut microbiome and negative affect in toddlerhood / Sarah C. VOGEL in Development and Psychopathology, 38-1 (February 2026)  

Public ISBD [article]  inDevelopment and Psychopathology > 38-1 (February 2026) . - p.301-313 Titre : Longitudinal associations between the infant gut microbiome and negative affect in toddlerhood Type de document : texte imprimé Auteurs : Sarah C.

WAGNER, Auteur Article en page(s) : p.301-313 Langues : Anglais (eng) Mots-clés : Gut microbiome infancy microbiome-gut-brain axis negative affect sensitive periods Index. décimale : PER Périodiques Résumé : The role of the gut microbiome in infant development has gained increasing interest in recent years. Most research on this topic has focused on the first three to four years of life because this is a critical period for developing gut-brain connections. Prior studies have identified associations between the composition and diversity of the gut microbiome in infancy and markers of temperament, including negative affect. However, the specific microbes affected, and the directionality of these associations have differed between studies, likely due to differences in the developmental period of focus and assessment approaches. In the current preregistered study, we examined connections between the gut microbiome, assessed at two time points in infancy (2 weeks and 18 months), and negative affect measured at 30 months of age in a longitudinal study of infants and their caregivers. We found that infants with higher gut microbiome diversity at 2 weeks showed more observed negative affect during a study visit at 30 months. We also found evidence for associations between specific genera of bacteria in infancy and negative affect. These results suggest associations between specific features of the gut microbiome and child behavior may differ based on timing of gut microbiome measurement.
