Antecedents and correlates of interracial behavior among high school students were assessed. Separate questionnaires were prepared for white and black students so that specific items referred explicitly to members of one's own race or to members of the other race. These questionnaires were completed by 750 students in an integrated high school that had experienced several months of racial conflict. Differential rates of avoidance and integrative behavior were observed when race, sex and school class were controlled. The racial differentials were found to be slight, but blacks consistently manifest integrative behavior more frequently than whites. Past equal status contact emerged as the strongest correlate of voluntary interracial behavior, followed by authoritarian personality characteristics and social pressures. Other important predictors of integrative behavior were prejudice, tendency to discriminate, fear of future competition and involvement in school activities. It was concluded that lack of knowledge about the antecedent of racial behavior are apparent in the limited success of programs designed to reduce racial prejudice. (Author/BW)
