Intrinsic goals do not have a positive effect on outcomes because of the qualities behind them, rather because they put a larger importance on learning. Intrinsically oriented students also do better on intrinsic goals.

Expectancy-Valence theories and the positive effects of intrinsic goals on performance

The negative effects of extrinsic goals are only prevalent with intrinsically oriented individuals. Further explained by a "match perspective" where  extrinsically oriented individuals perform better when goals are framed extrinsically.

Expectancy-Valence theories and the negative effects of extrinsic goals on performance

According to Expectancy-Valence theories, motivation for a goal is based on the quantity of perceived importance (or expected value) of that goal, rather than on the different qualitative types of goals (such as intrinsic versus extrinsic).

People behave based on the value that they perceive doing the behavior has to them. It takes into account expectancy (effort), instrumentality (performance) and valence (value/reward).

Expert program management: expectancy theory

Expectancy and value rating based on EVT can predict student effort on tasks. If a task is deemed as valuable, students will put more effort towards it, which can result in an increased likelihood of using desirable difficulties. Similarly, if a successful outcome is expected, a student will be more motivated to engage in difficult learning strategies. 

Task outcome expectancy/value

A theory of human motivation that posits that the reasons why an individual chooses to participate and exerts effort, are based on self-determined regulations (such as intrinsic motivation). It states there are 3 desires that promote optimal function and growth:
- 1) Autonomy
- 2) Competence
- 3) Relatedness
