A teacher wanted to know whether it hurts or helps your exam performance if you rethink and change some answers on a multiple-ch

oice test. Students in this study were told to review their final exams and change any answers they wanted to before turning them in. However, the students had to indicate both the original answer and the changed answer for each question. The teacher graded each exam twice, once using the set of original answers and once with the changes. Are the data sufficient to conclude that rethinking and (if necessary) changing your answers has an impact on test scores?

But the data given in this example are not sufficient to determine whether rethinking (and changing) hurts or helps.

Frankly I doubt it very much that you can determine such a thing because I feel that for some it will help and for others it will hurt.

The correct answer is the learning perspective. 

According to the learning perspective, fears and anxieties are a classically conditioned responses or learned responses. When a previously neutral stimulus is followed by an unpleasant or fear provoking stimulus, people develop a fear of previously neutral stimulus. Here, Andrea experiences anxiety when she approaches a lake, because she learned to fear lakes through a past fearful experience involving a lake.
