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.

Global COVID‐19 lockdowns have disrupted adolescents' in‐person social networks, increasing likelihood of loneliness. Social media can help adolescents maintain and develop peer relationships across distance. In this short longitudinal study with 735 Peruvian adolescents (ages: 11–17) from low‐to‐middle‐income urban settings, we investigated whether online experiences relate to loneliness during initial stages of lockdown. Loneliness remained constant between week 6 and 11 of lockdown, was higher for females and similar across school‐grades. Positive and negative online experiences were more frequent for older students, and females experienced more negative online experiences than males. Greater positive online experiences related to lower loneliness, with the reverse pattern for negative online experiences. Our results suggest that positive online experiences may mitigate loneliness during physical isolation.

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.

This study aimed to examine changes in depression and anxiety symptoms from before to during the first 6 months of the COVID‐19 pandemic in a sample of 1,339 adolescents (9–18 years old, 59% female) from three countries. We also examined if age, race/ethnicity, disease burden, or strictness of government restrictions moderated change in symptoms. Data from 12 longitudinal studies (10 U.S., 1 Netherlands, 1 Peru) were combined. Linear mixed effect models showed that depression, but not anxiety, symptoms increased significantly (median increase = 28%). The most negative mental health impacts were reported by multiracial adolescents and those under 'lockdown' restrictions. Policy makers need to consider these impacts by investing in ways to support adolescents' mental health during the pandemic.
