	Abstract

The present research argues that intergroup categorization has immediate behavioral consequences. Specifically, intergroup categorization is hypothesized to prepare the organism to respond differently to ingroup and outgroup members so that approach-like motor movements should be faster toward ingroup- versus outgroup-related stimuli. In contrast, avoidance-like behavior should be facilitated when reacting to outgroup versus ingroup members. Studies 1 and 2 test the basic hypothesis in relation to ethnic, national, age, and political categorization. Study 3 uses a minimal group paradigm to test the hypothesis in relation to newly formed groups. Across these experiments, participants were generally faster in performing approach-like motor movements toward ingroup members or avoidance behaviors toward outgroup members. The evolutionary function and the cognitive underpinnings of this state of "physical readiness" to approach ingroup and avoid outgroup members are discussed.
