Developmental science perspectives consider how exposure to early adversity undermines the normative development of self-regulatory processes in ways that compromise both short-and long-term health (Boyce & Ellis, 2005; O'Connor, 2003; Rudolph, Lansford, et al., 2016). Exposure to peer victimization (acts of physical, verbal, and psychological aggression) represents a particularly pernicious form of adversity. Not only is peer victimization common (Kochenderfer-Ladd & Wardrop, 2001), it forecasts a wide range of mental and physical health difficulties across the lifespan (McDougall & Vaillancourt, 2015). Given these pervasive and enduring effects, it is critical to understand processes through which victimization compromises development. Moreover, in line with differential susceptibility models of development (Boyce & Ellis, 2005; Ellis et al., 2011), it is important to determine which
