Twenty Black American males' reactions to slides depicting interracial climate and/or racial oppression were investigated by recording physiological responses, specifically, galvanic skin potential (GSP) and heart rate (HR). Participants were also given the Myers/Stokes Identity Scale (MSIS) to ascertain their reaction to oppression and, based on their scores, placed in one of these categories: "moving toward the oppressor,""moving away from the oppressor," and "moving against the oppressor." Analysis of variance tests were used to determine whether participants' reaction to oppression or the type of slide viewed (assimilation of Black Americans into Euro-American culture versus hierarchical cultural difference implying White as superior to Black) impacted on phasic and tonic GSP and HR. No effects were found, though the viewing of the slides per se caused significant physiological change on these measures. The participants did, however, rate slides depicting racial climate and/or racial oppression significantly differently as reflected in the significant main effects for slide type and participants' MSIS category, and the interaction between the two. Those who were "moving toward the oppressor" responded differently to slide rating than those "moving away from the oppressor" and "moving against the oppressor."
