In two studies this paper examines the influence of task framing on leadership emergence in mixed-gender dyads. In Study 1 we found that males are more likely to emerge as leaders when a paper-folding task is framed as masculine (i.e. Building Project) relative to feminine (i.e. Art Project). Furthermore females are more likely to emerge as leaders when a paper-folding task is framed as feminine relative to masculine. In Study 2we conceptually replicate these results using a weaving task (framed as Knot-Tying Task vs. Hair-Braiding Task) and find that perceived competence is the mechanism through which task framing affects leadership emergence. Taken together these results suggest that task framing can influence the emergence of leaders because of changes in perceptions of competence. These findings are discussed in the context of related theoretical findings and managerial implications are elaborated on.
