Question

Quizplus · Accepted Answer

Compensatory rivalry occurs when the control group expends extra effort to ensure that they are not outperformed by the experimental group. This can occur when participants in the control group feel that they are not receiving the same attention or benefits as the treatment group. As a result, they may put in extra effort to try and prove themselves, leading to an artificially inflated control group score.
