The effects of relative social Power on social motivation and behavioral confirmation were assessed. Participants, randomly assigned to the roles of perceiver and target, conversed over an intercom system as a prelude to choosing partners for an ostensibly subsequent reward-laden game. Relative power, was manipulated by giving 1 participant the power to choose a partner for the game. Also, perceivers received a game-related target expectation. Participants' motives and trait-based impression of their partners were assessed. High-power participants were more concerned with learning about their partners than low-power participants, who were generally more concerned with facilitating favorable interaction outcomes. Furthermore, whereas high-power perceivers effected behavioral confirmation from their targets, low-power perceivers did not. Implications of social power for motivationaI approaches to and understandings of expectation confirmation processes are discussed.
