This is a dissertation chapter on Vroom Expectancy Theory:
There are some theories that suggest motivation is thoughtful and rational decision-like process. One of the major theories from this type of approach is expectancy theory (e.g., Vroom, 1964). Expectancy theory basically says that people choose their behaviors based on the subjective estimation that such behaviors lead to the valued outcomes. Vroom’s valence-instrumentality-expectancy theory (VIE theory) states that there are three main components that affect human motivation. Valence is the degree in which the outcome the person will have is valuable for him/her. Instrumentality represents the degree in which the first outcome (e.g., performance) leads to the final valued outcome. Expectancy refers to the subjective probability that a certain effort or behavior leads to the first outcome or performance. VIE theory suggests that the multipricative function of valence, instrumentality and expectancy represents motivational force, which predicts a person’s choice (e.g., goal choice). (more…)
