The purpose of this research is to examine gender differences in promotion/prevention self-regulatory focus, a dispositional motivational orientation with major implications for human functioning. First, a review of literature using social cognitive theory as a framework suggests that, driven by socialization processes, (1) women may on average be more prevention focused than men - meaning more vigilant to maintain a secure status quo, whereas (2) men may on average be more promotion focused than women - meaning more eager to advance to a better situation than their status quo. Second, we provide data to examine these possible gender differences in self-regulatory focus with secondary analyses of (a) our own existing data on dispositional regulatory focus and of (b) a large scale, representative panel study (LISS Survey).

We put this assertion to a test by examining whether the effect of situationally induced goals depends on the goals that individuals personally self-adopt.

Bottom ranks may appear psychologically opposite to high power, which might lead one to expect that promotion-focused individuals experience fit at top ranks.
