The error-related negativity (ERN) is a potential neural vulnerability marker for anxiety. Although some studies have indicated that the ERN interacts with stressful life events to predict anxiety, these studies have only examined natural disasters or adult life stress, and it is thus unclear whether this vulnerability marker moderates the association between early life stressors and the development of psychopathology. To investigate, we assessed the past year stressor exposure of 180 nine- to 17-year-old girls using the Stress and Adversity Inventory for Adolescents, and self-report anxiety symptoms at baseline and 3 years later. At baseline, participants also completed a flanker task while electroencephalography was recorded to measure the ERN. As hypothesized, the ERN moderated the association between chronic interpersonal stressor exposure and both concurrent and 3-year follow-up anxiety symptoms. Specifically, greater chronic interpersonal stress was related to more concurrent and future anxiety symptoms, and this association was strongest in the context of a larger ERN. Error-related brain activity is thus an important moderating factor in the relation between chronic interpersonal stressor exposure and the development of anxiety symptoms across adolescence.</p>\u0000 </div>","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147590777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study focused on EEG data from 8-month-old infants to investigate the neural networks underlying the processing of naturalistic hand-to-hand touch—both felt and observed. Unlike prior research in which infants were presented with artificial stimuli, we employed ecologically valid, caregiver-like tactile interactions to better capture real-world dynamics. Our findings reveal that felt touch elicited widespread, highly coordinated gamma-band activity across sensory and higher-order cortical areas, supporting early integration of bodily experiences with attentional and perceptual systems. Observed touch, while activating a more localized somatosensory network, still demonstrated distinct gamma connectivity, consistent with early self-other differentiation. A control condition involving observed failed contact elicited increased frontal and temporal activity, possibly reflecting expectancy violation and heightened attentional demands. These results underscore the significance of touch in scaffolding early neural architecture, especially within sensorimotor and social–cognitive domains. Furthermore, our findings highlight the value of analyzing multiple frequency bands beyond traditional μ rhythm desynchronization to understand infant mirroring mechanisms. Importantly, this study advances our understanding of how early tactile experiences may shape the developing connectome, revealing gamma oscillations as a marker of sensorimotor processing and emerging intersubjective awareness.</p>\u0000 </div>","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147590694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unlike traditional rodent models that focus primarily on maternal care, the current study utilized the socially monogamous and biparental prairie vole (<i>Microtus ochrogaster</i>) to investigate how chronic preconception stress influences parental affect, pair-bonding, and parenting in both parents. Breeding pairs were assigned to either a stress exposure group, which underwent a 4-week chronic stress protocol (social isolation + mild unpredictable environmental stressors) prior to conception, or a no stress group (control). Chronic stress exposure did not induce anxiety- or depressive-like phenotypes or alter related hypothalamic activation in parents. However, stress-exposed parents exhibited atypical pair-bonding dynamics and a shift toward a proximity-based parenting style. Exploratory analyses revealed evidence for the intergenerational transmission of affective behavior and central oxytocin activation, primarily through maternal influences. In conclusion, chronic preconception stress can subtly disrupt the parental unit by altering pair-bonding quality and caregiving behavior, with potential consequences for offspring development. These findings highlight the family unit as a critical target for understanding and mitigating the intergenerational effects of stress.</p>\u0000 </div>","PeriodicalId":11086,"journal":{"name":"Developmental psychobiology","volume":"68 3","pages":""},"PeriodicalIF":2.2,"publicationDate":"2026-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147590750","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"心理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We used data on European Americans (EA) and African Americans (AA) from the Health and Retirement Study (HRS). Polygenic score for “ever smoking” (PGS<sub>smoking</sub>) was assessed using PRSice from a 2010 GWAS conducted by the Tobacco and Genetics Consortium. We operationalized PGS<sub>smoking</sub> as a binary variable: top 25% versus the rest. Ever smoking was assessed by asking participants if they had smoked 100 or more cigarettes in their lifetimes. EPFs included education levels of mother or father, perceived financial status, maternal warmth, and stressful events before age 18. We used logistic regression to assess the odds ratio (OR) for PGS<sub>smoking</sub>, EPFs, and their interaction terms in relation to ever smoking, adjusting for age, gender, and the five principal components. Among the 6969 EA participants (mean age: 74.3 years, 57% women), 55% reported ever smoking. Among the 2141 AA participants (mean age: 59.6, 67.3% women), 61.1% reported ever smoking.

Within the EA sample, high genetic risk was associated with a 25% higher likelihood of ever smoking (95% CI = 1.11–1.41), and low maternal warmth and PGS<sub>smoking</sub> showed significant additive interactions to increase odds of ever smoking.

We also probed pathways from community-level social determinants to biological markers and subsequent psychopathology symptoms. Using a longitudinal design, 211 families were followed during the first 2 years of life. Social determinants were assessed using US Census data, FAA using resting-state electroencephalogram, TL from infant saliva samples, and child psychopathology symptoms using the ITSEA. Statistical analyses included bivariate correlations (unadjusted and with false discovery rate adjustment for multiple comparisons) and SEM. For FAA, higher rates of uninsurance (healthcare) were associated with greater right lateralization at 2 months (<i>r</i> = −0.233, <i>p</i> = 0.028), and higher rates of food insecurity were also associated with greater right lateralization at 9 months (<i>r</i> = −0.250, <i>p</i> = 0.036); however, these associations were not significant after adjustment for multiple comparisons. In our SEM model, we found that both social determinants had paths to FAA (i.e., healthcare uninsurance rates to FAA at 2 months; food insecurity rates to FAA at 9 months), which had paths to child psychopathology symptoms at 2 years.
