Multiple-choice testing procedures that do not provide corrective feedback facilitate neither learning nor retention. In Studies 1 and 2, the performance of participants evaluated with the Immediate Feedback Assessment Technique (IF AT) , a testing method providing immediate feedback and enabling participants to answer until correct, was compared to that of participants responding to identical tests with Scantron answer sheets. Performance on initial tests did not differ, but when retested after delays of 1 day or 1 week, participants evaluated with the IF AT demonstrated higher scores and correctly answered more questions that had been initially answered incorrectly than did participants evaluated with Scantron forms. In Study 3, immediate feedback and answering until correct was available to all participants using either the IF AT or a computerized testing system on initial tests, with the final test completed by all participants using Scantron forms. Participants initially evaluated with the IF AT demonstrated increased retention and correctly responded to more items that had initially been answered incorrectly. Active involvement in the assessment process plays a crucial role in the acquisition of information, the incorporation of accurate information into cognitive processing mechanisms, and the retrieval of correct answers during retention tests. Results of Studies 1-3 converge to indicate that the IF AT method actively engages learners in the discovery process and that this engagement promotes retention and the correction of initially inaccurate response strategies.Testing and assessment are integral to the educational process. When university or college education takes place as tutorials or in classrooms with a small number of participants, essay examinations are preferred, as they are relatively easy to construct, they allow the instructor to assess the depth and breadth of participant understanding, and they

Students prepared for classroom examinations by completing practice tests, with selected items from these practice tests repeated, in either the original or in a modified wording, on classroom examinations and a final examination. The availability of immediate self-corrective feedback on Study 1 practice tests (0, 3, or 6 practice tests) was varied , while in Study 2, the timing of feedback provided during practice tests (immediate, end of test, 24-hour delay, control) was varied . Performance on examinations was elevated by the provision of immediate feedback on practice tests in both studies, especially when test items were presented in their original wording, with some generalization observed on items presented in a modified wording. Predictions made in accordance with the interference-perseveration hypothesis and the delayretention effect were not supported. These results demonstrate considerable potential for immediate self-corrective feedback, delivered during test preparation through the Immediate Feedback Assessment Technique, to enhance performance on classroom examinations and to promote the retention of factual information during the academic semester.

Students completed 5 quizzes during the semester using tesponse formats that provided no feedback (word-processed answer sheet, Scantron form), delayed feedback (end of test, 24 hours), or immediate feedback while answering each test item. Administered 2 weeks after students had completed the 5th quiz, the final examination consisted of 50 items, with 10 items randomly selected from each quiz. Scores on each quiz, time to complete each quiz, and average study time per quiz did not differ as a function of response format. Students demonstrated the highest recall, the most accurate identification of initial responses, the most confidence in their answers, and the least amount of perseverative incorrect responding on those final examination items that were originally responded to when immediate feedback was provided. These same students demonstrated less recall, less identification accuracy, lower confidence in their answers, and more perseverative incorrect responding on those final examination items that were originally responded to when either end of test or delayed feedback had been provided. Students' self-reports assessing how response format affected learning, retention, and confidence were consistent with quantitative outcomes. The present results support prior' demonstrations that combining immediate feedback with the opportunity to answer until correct not only assesses, but also teaches, in a manner that promotes the retention of course materials across the academic semester.

Performance on two multiple-choice testing procedures was examined during unit tests and a final examination. The Immediate Feedback Assessment Technique provided immediate response feedback in an answer-until-correct style of responding. The testing format which served as a point of comparison was the Scantron form. One format was completed by students in introductory psychology courses during unit tests whereas all students used the Scantron form on the final examination. Students tested with Immediate Feedback forms on the unit tests correctly answered more of the final examination questions which were repeated from earlier unit tests than did students tested with Scantron forms. Also, students tested with Immediate Feedback forms correctly answered more final examination questions previously answered incorrectly on the unit tests than did students tested previously with Scantron forms.

The Horizontal-Vertical (HV) Illusion was examined in two studies in which subjects adjusted the vertical line in L-shaped and inverted-T figures or produced lines in the vertical and horizontal planes. On the adjustment tasks, vertical lines were made significantly shorter than horizontal comparison lines, especially for the inverted-T figure. On the production tasks, lines drawn in the vertical plane were significantly shorter than lines drawn in the horizontal plane. The adjusted and created lines of subjects receiving intertrial feedback on illusion magnitude were significantly more accurate and less variable than the estimations of control subjects. Performance on either task or figure type did not differ as a function of sex of subject. The present results show that the HV illusion exists in the absence of line bisection or a comparison line and results from the overestimation of vertical lines. These findings further clarify the relative contributions of the structural and strategy mechanisms in the formation of the Horizontal-Vertical Illusion.

Participants completed 5 classroom examinations during which the timing of knowledge of results (no feedback: Scantron form; delayed feedback: end-of-test, 24 hour delay; immediate feedback: educator, response form) and iterative responding (1 response, up to 4 responses) were manipulated. At the end of the semester, each participant completed a 100-item final examination which included 10 items randomly selected from each classroom examination, plus 50 entirely new items. Neither the source of feedback nor the number of responses permitted influenced performance on classroom examinations but both factors interacted significantly to enhance the final examination performance of participants provided with immediate feedback and iterative responding. The correction of initially inaccurate strategies by combining immediate feedback with iterative responding was not differentially effective as a function of information source: educator or the Immediate Feedback Assessment Technique (IF AT) form. For these participants, response identification accuracy, confidence ratings, and retention were higher and inaccurate perseverative responding was lower. Performance on the final examination permits the preliminary quantification of how immediate feedback coupled with iterative responding, when used during classroom examinations that contain items that will be repeated on a cumulative final examination, not only assesses student knowledge but also teaches in a manner that promotes the retention of course materials.Many of the earliest studies conducted in the psychological sciences were dedicated to examining changes in the performance of learners provided with information (Le., feedback) that either affirmed a correct response or corrected an error (e.g., Thorndike, 1913Thorndike, , 1927. This corrective information, viewed initially within an associationistic framework as a contingent event, strengthened correct responses

The purpose of this study was to determine the influence of the D1-selective partial agonist SKF 38393 on the odor detection performance of rats using high precision olfactometry and a go/no-go operant task. Previous studies have found that the D2 receptor partial agonist quinpirole decreases such performance, but the influences of D1 receptor activation are unknown. In experiment 1, such detection performance to the odorant ethyl acetate was enhanced by SKF 38393, relative to saline, in male rats at 7.5 and 10.0 mg/kg i.p. dose levels, but not at the lower doses of 1.0, 2.5, and 5.0 mg/kg. In experiment 2, this enhancement was replicated at the 7.5 and 10.0 mg/kg doses and was shown to occur at the 12.5 mg/kg dose as well. In experiment 3, similar enhancement was shown for the odorant eugenol in female rats at the 7.5, 10.0 and 12.5 mg/kg doses, suggesting this effect is neither sex-specific nor confined to the odorant ethyl acetate. In experiment 4, a 0.025 mg/kg dose of the D1 receptor antagonist SCH 23390 depressed the enhancement produced to ethyl acetate by 7.5 mg/kg SKF 38393 to control levels. Overall, these data demonstrate that, in contrast to quinpirole, SKF 38393 improves odor detection performance in the rat and that this phenomenon can be attenuated by the D1 receptor blocker SCH 23390.
