The Relative Effects of Different Frequencies of Feedback on Work Performance

Abstract

This laboratory simulation examined the relative effects of two frequencies of feedback on work performance under hourly pay and incentive pay. The study had four experimental conditions: feedback delivered after every session under hourly pay and under incentive pay, and feedback delivered after every fourth session under hourly pay and under incentive pay. Thirty-five college students were randomly assigned to one of the four conditions. Each participant attended 24 thirty-minute sessions. Participants performed a simulated work task on the computer that consisted of computer-related activities such as dragging, clicking, and typing. The dependent variable was the number of correctly completed units of work. An analysis of covariance was conducted to analyze the data using pretest scores as a covariate. Participants who received feedback every session completed significantly more work units than participants who received feedback every fourth session. In addition, an interaction between feedback frequency and pay systems was found: Feedback delivered every session was more effective than feedback delivered every fourth session under the incentive pay system, but not under the hourly pay system. The results suggest that the relative effects of feedback frequency may depend upon the extent to which feedback is correlated with differential consequences for performance.
