The study takes place in a field setting at three different schools. Each group is composed of two black and two white students assigned randomly to either an experimental or control condition. Fourteen groups were run for each condition or a total of 28 groups. In the control condition both blacks and whites receive the same neutral training procedure including the basic rules for playing a game of strategy. The training is given to the whole group, separating racial pairs into two different rooms. In the experimental condition, black subjects receive an assertion training while the white subjects receive the neutral control training procedure. Following the training period the group reassembles in the game room and plays the game of strategy. Observers score initiation and influence to document the emerging power and prestige order for each group. The white subjects were more active in the control groups. In 64 percent of the experimental groups, however, blacks hold one of the high-ranking positions. According to the index of initiation rates, the status ordering in the experimental condition is the reverse of the control condition; blacks dominate instead of whites. Further the improvement of black performance does not entail a significant reduction in white activity. [Not available in hard copy due to marginal legibility of original document.] (Author/ JM)
