The effects of task importance and publicness on the relation between goal difficulty and performance.

In a laboratory study using undergraduate students (N?=?200), perceived task importance was found to moderate the relationship between goal level and performance. Moreover, participants performed better when both the goal and performance were public rather than anonymous. These findings suggest that by manipulating task importance and publicness of performance, it is possible to influence the impact that the difficulty of specific goals have on performance. The results are consistent with our hypotheses that the motivation to preserve one's self-image and the motivation to preserve one's public-image are two factors that determine effort and persistence devoted to assigned goals.
