Abstract Recent research has shown that achievement goals differ in their effects on working memory capacity and the metacognitive judgment of learning as part of the self-regulatory process. To extend this line of inquiry, we examined the effects of achievement goals on self-control, arguably the most critical subset of self-regulation. In three experiments, adolescent and early-adult learners were randomly assigned to mastery goal, performance-approach goal, and performance-avoidance goal conditions and performed self-control tasks in ego-depleting contexts. Students in the mastery goal condition demonstrated significantly better performance than students in the performance-approach goal condition on a task that required attentional control (Experiment 1) and inhibitory control after negative feedback (Experiments 2 and 3). The performance of students in the performance-avoidance goal condition did not differ significantly from that of students in the mastery goal or the performance-approach goal conditions. Planned-comparison ANCOVAs nonetheless revealed that, across all three experiments, the self-control performance of the students in the mastery goal condition was significantly better than that of the students in the two performance goal conditions combined. Mediation analysis further suggested that performance-approach and performance-avoidance goals evoked more task-irrelevant thoughts than mastery goals did, which subsequently interrupted students’ self-control performance (Experiment 3). We discuss the implications of the mechanisms underlying motivational influences on self-control for adolescents, who experience frequent self-regulation failures in learning contexts.
