Joint Effect of Feedback and Goal Setting on Performance: A Field Study of Residential Energy Conservation

Becker, L. J. (1978). Joint effect of feedback and goal setting on performance: A field study of residential energy conservation. Journal of Applied Psychology, 63, 4, 428-433.
The facilitating motivational effect of feedback on performance has been attributed by some to difficult goals set in response to feedback. The present experiment attributes this effect to the presence of both a difficult goal and feedback about performance in relation to that goal. 80 families were asked to set a goal to reduce their residential electricity consumption for several weeks during the summer, half of them by 20% (a difficult goal) and half by 2% (an easy goal). Within each of these groups, half of the families were given feedback 3 times/wk about their consumption. 20 more families served as a control group. As predicted, the 20%-feedback group conserved the most (13.0-15.1%) and was the only one that consumed significantly less electricity than the control. It is concluded that improved performance was a result of the joint effect of feedback and goal setting. The implications of the present research for a national residential conservation strategy are discussed. (20 ref)
