Theory and research highlight the mismatch between puberty-associated challenges and personal coping resources among youth with early actual or perceived pubertal timing. This study (N = 167; M[subscript age] = 12.41 years; 51.5% female; 77.8% White American) examined whether coping resources provided by mothers (maternal socialization of coping)…

Increasing research shows pubertal development accelerates following threats while it decelerates following deprivation. Yet, these environmental stressors are unlikely to occur in isolation. We investigated how war exposure and energetic stress impact pubertal development using data from the longitudinal Biological Pathways of Risk and Resilience…

Based on the "Differential Susceptibility Theory," we examined whether the relationship between pubertal maturation and depressive symptoms can be moderated by individual differences in environmental sensitivity. The current article used the three-wave data collected from Japanese adolescents aged from 12 to 15 years (girls = 111,…

During adolescence, increases in pubertal hormones lead to reproductive maturity as well as changes in cognitive development.
