Developmental mechanisms linking deprivation and threat to psychopathology and school outcomes / Nicolas MURGUEITIO in Development and Psychopathology, 37-3 (August 2025)

PROPPER, Auteur Article en page(s) : p.1593-1604 Langues : Anglais (eng) Mots-clés : Achievement  deprivation  psychopathology  threat Index. décimale : PER Périodiques Résumé : Background:Decades of evidence have elucidated associations between early adversity and risk for negative outcomes. However, traditional conceptualizations of the biologic embedding of adversity ignore neuroscientific principles which emphasize developmental plasticity. Dimensional models suggest that separate dimensions of experiences shape behavioral development differentially. We hypothesized that deprivation would be associated with higher psychopathology and lower academic achievement through executive function and effortful control, while threat would do so through observed, and parent reported emotional reactivity.Methods:In this longitudinal study of 206 mother-child dyads, we test these theories across the first 7 years of life. Threat was measured by the presence of domestic violence, and deprivation by the lack of cognitive stimulation within the parent-child interaction. We used path analyses to test associations between deprivation and threat with psychopathology and school outcomes through cognition and emotional reactivity.Results:We show that children who experienced more deprivation showed poor academic achievement through difficulties with executive function, while children who experienced more threat had higher levels of psychopathology through increased emotional reactivity.Conclusion:These observations are consistent with work in adolescence and reflect how unique adverse experiences have differential effects on children s behavior and subsequently long-term outcomes.

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. VOGEL, Auteur ; Nicolas MURGUEITIO, Auteur ; Nicole HUTH, Auteur ; Kathy SEM, Auteur ; Rebecca C. KNICKMEYER, Auteur ; Sarah J. SHORT, Auteur ; Roger MILLS-KOONCE, Auteur ; Cathi PROPPER, Auteur ; Nicholas J. 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.
