title: Differential effects of feedback sensitivity upon learned control of skin temperature.
abstract: Ninety subjects participated in a skin temperature biofeedback study concerning the effects of feedback sensitivity. Subjects were randomly assigned to a high sensitivity, low sensitivity, or a no-feedback condition. Based upon previous research, it was predicted that the low sensitivity condition would produce superior skin temperature warming and greater reduction of autonomic arousal. Also, it was predicted that both feedback conditions would be superior to the no-feedback condition for skin temperature control and reduction of autonomic arousal. The results indicated that low sensitivity feedback was not superior to high sensitivity feedback for skin temperature control, but did produce greater reduction of autonomic variables. The prediction that feedback was superior to no-feedback was also confirmed.
