What phenomenon explains the tendency of test-takers to score better when re-taking tests?

• A. Learning effect
• B. Test-retest effect
• C. Familiarity effect
• D. Practice effect

Answer: (B)

The correct answer is the test-retest effect, which refers to the phenomenon where individuals tend to score higher on assessments when they take the same test multiple times. This effect is largely attributed to the familiarity that test-takers gain with the test format, types of questions, and content after their initial experience. As a result, when they retake the test, they are likely to perform better due to this familiarity and the opportunity to learn from their previous performance. While learning effect may also contribute to improved scores due to knowledge retention over time, it is not specifically tied to the repeat-taking of the same test. Similarly, the familiarity effect emphasizes how prior exposure can enhance performance, but it does not encapsulate the broader systematic improvement seen through repeated measures as the test-retest effect does. The practice effect, on the other hand, focuses on the improvement resulting specifically from repeated practice of similar tasks or skills, rather than the context of retaking an identical test. Thus, the test-retest effect is the most fitting answer for explaining why people generally score higher when they retake a test.
