Reward
From the Simple English Wikipedia, the free encyclopedia that anyone can change
A reward is a benefit for performing a given task. It assumes someone in a position to evaluate and judge goodness.
Concepts like risk and reward, reward and punishment are based on the idea that people do things, or avoid doing things, due to rewards. In psychology there is evidence that they do not, and that conditioning and affective factors are much more important than the rewards or punishments of outsiders.
