AbstractIn this study we examined the development of three action monitoring event‐related potentials (ERPs) – the error‐related negativity (ERN/Ne), error positivity (PE) and the N2 – and estimated their neural sources. These ERPs were recorded during a flanker task in the following groups: early adolescents (mean age = 12 years), late adolescents (mean age = 16 years), and adults (mean age = 29 years). The amplitudes of the ERN/Ne and N2 were greater in the adult and late adolescent groups than in the early adolescent group. Both of these components had neural sources in the anterior cingulate cortex (ACC). Although PE was present across groups, PE amplitude was greater in the late adolescent group compared to the adult group and also had neural sources in the ACC. ERN/Ne amplitude was related to post‐error slowing across age groups; it was related to task performance only in the adult group. These findings are discussed in light of the role of the maturation of the ACC in the development of action monitoring processes.

There is major concern about the impact of the COVID‐19 pandemic on adolescent suicidal ideation (SI) and peer relationships. We investigated (1) rates of SI and (2) the extent to which peer connectedness and pre‐existing neural activation to social reward predicted SI during the initial stay‐at‐home orders of the pandemic (April–May 2020) in a longitudinal sample of adolescent girls (N = 93; Mage = 15.06; 69% White non‐Hispanic). Daily diary and fMRI methods were used to assess peer connectedness and neural activation to social reward, respectively. Nearly 40% of girls endorsed SI during the initial stay‐at‐home orders. Greater peer connectedness and neural responsivity to anticipated social reward were associated with a reduced odds of SI during the pandemic among girls.

Research suggests that altered emotion processing may be one important pathway linking social risk factors and depressive symptoms. We examined the extent to which neural response to negatively valenced social information might help to account for the relationship between social risk and depressive symptoms in youth. Forty‐nine youth were scanned while identifying the emotional valence of words that connoted social status. They also completed questionnaires assessing self‐reported social risk factors and depressive symptoms. Mediation analysis revealed that reduced dorsolateral prefrontal cortex activity in response to negative social status words explained the positive association between social risk and depressive symptoms. These findings suggest that social risk factors present during adolescence may contribute to depressive symptoms by influencing the neural substrates of emotion processing.

This study investigated the association between maternal affective expression during laboratory‐based interaction tasks and adolescents' experience of positive affect (PA) in natural settings. Participants were 80 healthy adolescents and their mothers. Durations of maternal positive (PA) and negative affective (NA) expressions were observed during a conflict resolution task and a positive event planning interaction task. Ecological momentary assessment (EMA) procedures were employed to assess adolescents' momentary and peak experience of PA in daily life. Results indicated that maternal NA, but not maternal PA, was related to adolescents' EMA‐reported PA. Adolescents whose mothers expressed more NA experienced less PA in daily environments. Results suggest that adolescents' exposure to maternal negative affective behavior is associated with adolescents' subjective daily well‐being.

AbstractThe ways parents socialize their adolescents to cope with anxiety (i.e., coping socialization) may be instrumental in the development of threat processing and coping responses. Coping socialization may be important for anxious adolescents, as they show altered neural threat processing and over reliance on disengaged coping (e.g., avoidance and distraction), which can maintain anxiety. We investigated whether coping socialization was associated with anxious and healthy adolescents' neural response to threat, and whether neural activation was associated with disengaged coping. Healthy and clinically anxious early adolescents (N = 120; M = 11.46 years; 71 girls) and a parent engaged in interactions designed to elicit adolescents' anxiety and parents' response to adolescents' anxiety. Parents' use of reframing and problem solving statements was coded to measure coping socialization. In a subsequent visit, we assessed adolescents' neural response to threat words during a neuroimaging task. Adolescents' disengaged coping was measured using ecological momentary assessment. Greater coping socialization was associated with lower anterior insula and perigenual cingulate activation in healthy adolescents and higher activation in anxious adolescents. Coping socialization was indirectly associated with less disengaged coping for anxious adolescents through neural activation. Findings suggest that associations between coping socialization and early adolescents' neural response to threat differ depending on clinical status and have implications for anxious adolescents' coping.
