Skin temperature biofeedback for multiple sessions with monetary incentives.
This study evaluated the relative effectiveness of two incentive contingencies in learning biofeedback-assisted control of peripheral skin temperature: positive versus positive/negative monetary incentives. Both incentive groups of 10 participated in six sessions, including pre- and posttraining voluntary control sessions, and four intervening sessions with visual feedback and monetary contingencies. Each session consisted of adaptation, resting baseline, feedback or voluntary control, and a final resting baseline. The results indicated no significant difference in response control between groups and an over-all decline in temperature within sessions. Self-control was evidenced by the slower rate of decline in temperature for the first as compared to the last session, and feedback control by the attenuation in the rate of decline in the last three training sessions. Based on data from other physiological responses, these findings are not likely due to habituation effects. It was concluded that response control should not necessarily be defined in terms of increasing temperature but rather by reference to an appropriate comparison condition. Motivational effects should be further investigated with alternative incentive contingencies.
