In this study we argue that when powerholder and target operate in a cooper
ative context, the decision to use power is influenced by the motive to rea
ch positive joint outcomes. When the context is competitive, the use of pow
er is more dictated by the desire to gain positive outcomes at the expense
of the target. Therefore, factors that are indicative of how to bring about
positive outcomes for the target will only influence power use in a cooper
ative context The results of an experimental study with a 2 (social context
: cooperation vs. competition) x 2 (relative competence: high vs. low) betw
een-subjects design, with task components generating 2 levels of confidence
as within-subjects variable, supported our line of reasoning. Competence o
f the powerholder as well as confidence as elicited by the task only affect
ed power use in cooperation and not in competition. The results also indica
ted that the absolute level of power use in competition and cooperation did
not differ.
