Effects of differential feedback on opinions of and responses to intelligence tests

On 2 separate occasions, 160 college Ss were administered both an IQ test and a test opinion scale in counterbalanced orders. Ss received differential feedback information presumably drawn from their earlier IQ test's performance before the 2nd administration. Feedback significantly affected subsequent retest IQ test score and opinion scale scores. Order of testing was a significant variable in the test-feedback-retest condition. It is concluded that when the testing situation is viewed as a complex interaction of stimuli, S, and situational variables, the variables investigated can systematically and significantly affect the performance of the examinee.
