Accurately assessing emotional responses that occur during intergroup interactions is difficult. Educational, institutional, and cultural socialization efforts that promote the value of, and sensitivity toward, ethnic and racial4 diversity may exaggerate differences between expressed and experienced feelings and attitudes toward members of minority groups. Not surprisingly, psychologists have become increasingly, but not exclusively, attracted to less consciously controlled or implicit measures of affect within the context of intergroup interactions. My talk will focus on the value of using multiple measures, including both less consciously controllable and more consciously controllable ones, in the study of intergroup interactions. First, I will provide a brief review of the biopsychosocial model of arousal regulation, which relies on the integration of cognitive appraisals, affect, and cardiovascular responses to determine motivational states that are appetitive (challenge) versus aversive (threat). Following this review, I will discuss a series of studies that incorporates these measures to examine perceivers' emotional and physiological reactions during dyadic intergroup interactions. I will conclude with a discussion of a meta-analysis of these studies organized within a multi-method matrix that demonstrates convergences and divergences among less and more consciously controllable measures as a function of the interaction partner's race.
