Self-Discrepancy Theory

Self-discrepancy theory identifies three self-representations: the actual self—what someone believes they truly are; the ideal self—what they aspire to become; and the ought self—what they feel obligated to be based on duties and social demands. These three interpretations shape how people evaluate themselves and motivate their behavior.

When people fall short of their ideal self, they experience negative emotions like dejection and shame. For example, a poor singer who dreams of becoming a rock star feels dejected when criticized because his actual self diverges from his ideal self. These emotional consequences motivate people to close the gap through goal-directed behavior.

Promotion focus is a motivational strategy emphasizing positive approaches and desired outcomes. When pursuing ideal self goals, people use promotion focus by concentrating on success and optimistically pursuing improvement. For instance, someone aspiring to be a better singer uses promotion focus by optimistically signing up for vocal lessons to achieve their ideal goal.

Prevention focus emphasizes avoiding negative outcomes and mitigating potential problems, typically motivated by ought self concerns. When someone feels obligated to be a supportive sibling but struggles with their brother's noise, they use prevention focus by avoiding situations that might damage their relationship, protecting their sense of duty.

Ego depletion is a state where someone lacks the mental energy or resources to engage in further self-control after exerting effort to meet ideal or ought standards. Living up to these standards is mentally taxing, so individuals may experience reduced capacity for self-regulation. However, most situations do not completely drain self-regulatory resources.

When people automatically bring important goals to mind, they can diminish immediate temptations without depleting self-control resources. For example, someone focused on eating healthily quickly recalls this goal when facing donuts, reducing temptation thoughts and enabling long-term objective achievement without exhausting mental energy.

Procrastination often reflects a discrepancy between actual and ought selves—people fail to complete tasks they believe they should complete. This mismatch creates dissatisfaction with the self and motivates behavior change. The theory explains why procrastinators experience negative self-evaluation and the emotional consequences that drive them toward task completion.
