Feeling both victim and perpetrator: investigating duality within the needs-based model.

Victimized versus perpetrating individuals or groups are known to experience enhanced needs for empowerment or acceptance, respectively. The present research examined the emotional needs and consequent anti- and prosocial behaviors (e.g., vengefulness vs. helpfulness) of individuals or groups serving both as victims and perpetrators simultaneously ("duals"). Focusing on interpersonal transgressions, Study 1 used variations of the dictator game to induce participants with victimization, perpetration, duality, or none (control). Duals showed heightened needs for both empowerment and acceptance and equal willingness to reconcile following either empowering or accepting messages from their adversaries. However, duals' need for empowerment overrode their need for acceptance in determining behavior. Similar to victims, and unlike perpetrators, duals showed greater antisocial (rather than prosocial) behavior. Study 2 replicated this pattern on the intergroup level, inducing Israeli Jews with victimization, perpetration, or duality using a recall task referring to the Israeli-Palestinian conflict. Theoretical and practical implications are discussed.
