Providing an external reward for a behavior that is already intrinsically motivated may result in a sense of irritation. refusal to accept rewards of any kind. slower rate of learning. reduction in the rewarded behavior. new locus of control.

The correct answer is letter C. reduction in the rewarded behavior.

Explanation:

If an activity is intrinsically motivated, that means the person already finds it interesting and fun, doing it just for the sake of doing it. They do not expect anything in return since the activity itself is rewarding enough for them. Studies have shown that an intrinsically motivated person, when rewarded with an external reward - money, feedback, etc. - tends to reduce the behavior (activity). That is called overjustification effect. The person begins to struggle with the real reason why they are doing that activity. The external reward interferes with the way they perceive the behavior and themselves, causing a reduction in performance.
