Question

Quizplus · Accepted Answer

Memory can impact test-retest reliability by causing an overestimation of the true reliability. If participants remember their responses from the first test administration when they are retested, their scores may be more similar across the two testings than they would be if memory were not a factor. This increased similarity can lead to an inflated estimate of the test's reliability.
