Expectancy-Value Theory
Updated 2026-08-13
INTRODUCTION
English translation pending.
CORE DEFINITION
A person's motivation to do something is the product of two factors: expectancy, can I actually do this, and value, does this matter to me. If either is zero, motivation is zero. The model is a diagnostic for procrastination: when you cannot move, check whether you lack belief in success or meaning in the task, then fix whichever is missing.
SCAFFOLDING EFFECT
Reduce cognitive load
- Diagnose the stall: when you cannot move, ask whether belief or meaning is missing. - Fix the right half: build confidence if expectancy is low, reconnect purpose if value is low. - Treat them as multiplied: remember that one near-zero factor nullifies the other.
Anchor fast decisions
In this motivation and decision theory, behavioral tendency equals success expectation, a self-efficacy belief, multiplied by task value, the goal's importance. Because the two combine multiplicatively, either one approaching zero drives motivation toward zero as well.
