Temporal Motivation Theory is the most comprehensive model for explaining why we procrastinate. It holds that motivation for a task depends on four factors: the expected value of the outcome, perceived probability of success, delay sensitivity (how much it affects us that the result is distant), and the proximity of the deadline. Large, distant, uncertain tasks always have low motivation.
Concept origin
Piers Steel and Cornelius König (2006) integrated previous theories of motivation, procrastination, and hyperbolic time discounting into TMT. Steel formalized it in his meta-analysis (2007) and his book "The Procrastination Equation" (2010). It is the model with the most empirical support in the field.
Therapeutic approach
TMT suggests concrete interventions: increase perceived value (connect the task to personal values), increase self-efficacy (break into manageable steps), reduce delay sensitivity (create artificial intermediate deadlines), and reduce impulsivity (Pomodoro, distraction blocking).
