Abstract
The persistence of intergroup conflicts around the world creates urgency for research on child development in such settings. Complementing what we know about internalizing and externalizing developmental outcomes, in this article, I shift the focus to children’s prosocial behaviors and more specifically, the Developmental Peacebuilding Model (DPM). The DPM makes three main contributions: It (a) integrates a developmental intergroup framework and socioecological perspective with a peace‐building paradigm to examine the target and type of children’s prosocial behavior in settings of intergroup conflict; (b) outlines how children’s outgroup prosocial behaviors, which promote constructive change at different levels of social ecology, can be understood as peace building and fostering social cohesion; and (c) has implications for research and global policy.
