Abstract
How people respond to desires varies substantially across time and situations. Building on recent theoretical developments, we propose that motivation plays a central role in the dynamics of self-control as it unfolds across time. We illustrate the role of motivation in self-control by highlighting evidence that pursuing goals for intrinsic (vs. extrinsic) reasons plays a key role in shaping when and how people engage in self-control in service to their goals. We then expand this framework by outlining several promising directions for future research, specifically emphasizing the dynamic interplay between motivation and self-control at various stages in the regulation process. Ultimately, we posit that motivation is a key factor in helping people flexibly regulate desires in accordance with situational demands.
