According to expectancy-value theory, the amount of effort a person is likely to expend on a goal is determined by the value of the goal and the person's estimation of how achievable it is. If the person values the goal highly and believes it is attainable, they are more likely to invest a significant amount of effort into achieving it. Factors such as the opinions of others and cultural values may also play a role, but they are not the primary determinants of effort expenditure according to this theory.
