Final answer:
Maggie is exhibiting 'stereotyped behavior' by persistently following a study strategy that consistently results in poor quiz performance without changing her approach.
Step-by-step explanation:
Maggie's continued use of a strategy that has resulted in consistent poor performance on her psychology quizzes falls under the definition of stereotyped behavior. This term describes a fixed, repetitive pattern of behavior that does not vary, even when it is not providing beneficial results.
In Maggie's situation, despite the strategy not leading to the achievement of an A on the quizzes, she continues to read the chapter thrice before each quiz. Psychologists would suggest that her behavior is unadaptive because it persists despite negative outcomes, and it might be beneficial for Maggie to try alternative study methods to improve her quiz scores.
