This project examined a reinforcement learning model of conformity and social influence. Under this model, individuals value consensus-or agreement with groups-and conformity represents a strategy for maximizing consensus with a group. Under this project, we examined three predictions that emerge from a reinforcement model. First, people effects of social influence should generalize, such that people should agree with groups not only about particular exemplars (e.g., foods or paintings), but

ABSTRACT Number of Papers published in peer-reviewed journals: Number of Papers published in non peer-reviewed journals: This project examined a reinforcement learning model of conformity and social influence. Under this model, individuals value consensusor agreement with groups-and conformity represents a strategy for maximizing consensus with a group. Under this project, we examined three predictions that emerge from a reinforcement model. First, people effects of social influence should generalize, such that people should agree with groups not only about particular exemplars (e.g., foods or paintings), but also about rules governing group behavior. Second, people should be most inclined to conform when they experience social "hunger," such as isolation or rejection. Third, people should act more prosocially towards individuals who conformed with them (i.e., offer consensus). Predictions 1 and 3, but not 2, were borne out by our research.
