Because avoiding obstacles to goal attainment is a favored means of prevention-focused self-regulation, the authors proposed that resisting tempting diversions from task completion would better fit a prevention focus than a promotion focus, thus affecting task enjoyment and performance. Whether deciphering encrypted messages (Study 1) or solving math problems (Study 2), when exposed to attractive distracting video clips, participants in a prevention focus reported greater task enjoyment than did participants in a promotion focus, whereas the reverse was true when the distracting clips were not presented. Indeed, prevention-focused participants enjoyed the tasks more when they had to resist temptation than when they did not. In Study 2, prevention-focused participants outperformed promotion-focused participants under distracting (but not nondistracting) conditions, and regression analyses suggested that task enjoyment mediated this effect. Different regulatory states thus appear to differentially equip people to deal with tempting diversions from goal attainment.
