This Technical Report presents the theoretical account for relations among power and prestige behaviors in small groups and performance expectation states. It explains, among other things, the high correlations among several different behaviors and their relations to estimates of ability and choices for leadership among group members. It is the first full exposition of this theory, as well as of the now-standard analysis of interaction patterns and how they lead to expectation states and then maintain patterns of the states and of inequality. This Technical Report was revised as Technical Report #31
