EPP TEST C EXAM QUESTIONS AND DETAILED ANSWERS 2. A graduate student is conducting intelligence testing on ten subjects. Prior to the testing, the graduate student chooses five subjects at random, and tells each of them she believes he or she is gifted. These examinees perform significantly better overall than examinees who are not given this information. This is an example of: 1. the Zeigarnik effect. 2. the Hawthorne effect. 3. the Rosenthal effect. 4. the halo effect. - ANSWER Feedback: Correct answer 3.
