Skin temperature biofeedback: evaluation of positive and negative monetary incentives.

The purpose of the present experiment was to evaluate how training procedure and monetary incentive affect skin temperature biofeedback: A 3 (training procedure) X 3 (monetary incentive) design was employed. It was hypothesized that positive and negative monetary feedback would enhance temperature control. Motivation was manipulated by paying subjects 1 cent, 10 cents, or 20 cents for every 0.1 degree F they decreased their finger temperature over baseline for three days. Results revealed a significant monetary effect only during the first training day.
