Abstract: The aim of this study is to search into the relationship of types andapproaches of feedback to performance. In the study, 120 subjects wererequired to finish a task both requesting quality and quantity. A 3×3experimental design (three levels of feedback crossed with three levelsof approach) with an additional control group was used. The results in-dicated: 1. In general, the performance of the feedback groups werebetter than that of the control group.2.The level of performance was affec-ted by the nature of feedback. The performance of the quality-and-qu-antity feedback was significantly better than that of other types of feedback.3.Individual performance might be improved by the free-choice andregular feedback. 4. The combination of free-choice and regular feedbackand the quality-and-quantity feedback was the best model-control withthe goal of reaching higher performance.
