Jill is motivated by money and the things money will bring her. Jack is motivated by a belief in the importance of doing good things, and his incentives are based on that belief. Which theory incorporates both these types of motivational causes?

The theory that incorporates both these types of motivational causes is the expectancy-value theory.

Explanation:

Expectancy-value theory has been developed by Jacquelynne Eccles and her colleagues. According to this theory, motivation for a certain behavior or action is determined by two factors: expectancy and value. Expectancy refers to the probability of a behavior or action leading to a desired outcome. Value concerns how much an individual values the desired outcome. From the description, we can see both Jill and Jack are motivated. They both probably work hard. However, Jill's motivation comes from a more extrinsic reason, since she values wealth. Jack's motivation is intrinsic, since he values goodness and generosity.
