Metacognitive knowledge about self-control

Good self-control is highly valuable, but the processes that promote it are not fully understood. This review emphasizes that self-control is “inherently metacognitive” (p. 204, Duckworth et al., 2014) and describes the potential benefits of metacognitive knowledge for self-control. In line with research on metacognition in academic goal pursuit, we elaborate how three distinct types of metacognitive knowledge may aid self-control: strategy knowledge (for example, a repertoire of self-regulatory strategies), task knowledge (for example, understanding self-control demands), and person knowledge (for example, awareness of one's self-control strengths and weaknesses). Additionally, we identify research gaps and suggest that future studies should investigate the development and updating of metacognitive knowledge about self-control and how metacognitive knowledge can prevent individuals from justifying indulgence.
