Self-control is a relevant concept for understanding human behavior across different areas of life. It is associated with positive aspects in various domains and has a pragmatic value as a prerequisite for the successful achievement of long-term goals. In this regard, there are different theories and approaches to the study of self-control. Gaining a deeper understanding of the psychological mechanisms involved in this capacity could guide the design of more effective strategies to foster its development across different contexts. This narrative review article focuses on an updated overview of two of the main theoretical models of this construct, identifying potential similarities and differences. First, Roy F. Baumeister’s model proposes that self-control is a limited resource similar to a muscle. Self-control fatigue is known as “ego depletion”. Second, Kentaro Fujita’s model s...
