Two studies of task-focused dyads tested the approach/inhibition theory of power (D. Keltner, D. H. Gruerifeld, & C. Anderson, in press), which posits that having power increases the tendency to approach and decreases the tendency to inhibit. Results provided preliminary support for the theory: Participants' higher in personality dominance or assigned control over resources expressed their true attitudes; experienced more positive and less negative emotion, were more likely to perceive rewards (i.e., that their partner liked them), and were less likely to perceive threats (e.g., that their. partner felt anger toward them). Most of these effects were mediated by the sense of power, suggesting that subjective feelings of power are an important component in the effects of power.
