PURPOSE OF THIS STUDY WAS TO EVALUATE THE EFFECTS OF AN IMMEDIATE FEEDBACK DEVICE ON LEARNING, RETENTION, AND ATTITUDES OF 264 COLLEGE STUDENTS IN A BEGINNING PSYCHOLOGY COURSE. LECTURES WERE PRESENTED ON CLOSED CIRCUIT TELEVISION. A CONTROL GROUP USED THE DEVICE ONLY TO PREVENT COPYING OF THEIR ANSWERS BY OTHER STUDENTS. NO SIGNIFICANT DIFFERENCES WERE FOUND IN POST TEST ACHIEVEMENT SCORES, NOR DID SEX OR ABILITY DIFFERENCES HAVE ANY EFFECT. STUDENT ATTITUDES WERE FAVORABLE. VALUE OF THE DEVICE SEEMED TO LIE IN SAVING TEST REVIEW TIME. (LH)
