An examination was made of the effects of the black caucus and the women's caucus on the American Psychological Association (APA). Black psychologists charged the APA with racism and female psychologists charged the organization with sexism. Both groups demanded changes in APA governance structure and policy. The demands of the two groups and responses of the APA to those demands were investigated within the context of a historical review of events. Findings of the examination indicated that the influence of the women's caucus in psychology made a major impact on the APA. The black caucus had less of an impact as a result of its withdrawing from the APA. Both groups sensitized the organization to the issues of racism and sexism within psychology. (Author/MK)
