 That is, a person's own perceptions or attributions as to why they succeeded or failed at an activity determine the amount of effort the person will engage in activities in the future.Weiner suggests that individuals exert their attribution search and cognitively evaluate casual properties on the behaviors they experience.When attributions lead to positive affect and high expectancy of future success, such attributions should result in greater willingness to approach to similar achievement tasks in the future than those attributions that produce negative affect and low expectancy of future success.
