Prosocial development in adolescence.

In this review, we describe the development of prosocial behavior in adolescence as a critical inflection period for social adjustment. Experimental research using prosocial giving tasks demonstrates that adolescents differentiate more between recipients and contexts, suggesting increasing ingroup-outgroup differentiation during adolescence. We also demonstrate that social brain development during adolescence is partly driven by environmental influences, further underlining adolescence as a critical period for social development. The COVID-19 pandemic has had and will have long-term effects on the current generation of adolescents, for which we describe both the risks, resilience factors, and opportunities for engaging in prosocial acts of kindness.

Perceived stress as mediator for longitudinal effects of the COVID-19 lockdown on wellbeing of parents and children.

Dealing with a COVID-19 lockdown may have negative effects on children, but at the same time might facilitate parent-child bonding. Perceived stress may influence the direction of these effects. Using a longitudinal twin design, we investigated how perceived stress influenced lockdown induced changes in wellbeing of parents and children. A total of 106 parents and 151 children (10-13-year-olds) filled in questionnaires during lockdown and data were combined with data of previous years. We report a significant increase in parental negative feelings (anxiety, depression, hostility and interpersonal sensitivity). Longitudinal child measures showed a gradual decrease in internalizing and externalizing behavior, which seemed decelerated by the COVID-19 lockdown. Changes in parental negative feelings and children's externalizing behavior were mediated by perceived stress: higher scores prior to the lockdown were related to more stress during the lockdown, which in turn was associated with an increase in parental negative feelings and children's' externalizing behavior. Perceived stress in parents and children was associated with negative coping strategies. Additionally, children's stress levels were influenced by prior and current parental overreactivity. These results suggest that children in families with negative coping strategies and (a history of) parental overreactivity might be at risk for negative consequences of the lockdown.
