Biofeedback vs. instructional control of skin temperature

Area of Science:

• Psychophysiology
• Behavioral Medicine

Background:

• Self-regulation of physiological processes is crucial for health.
• Understanding the efficacy of different training methods for self-control is important.

Purpose of the Study:

• To compare the effectiveness of instructions versus biofeedback in developing skin temperature self-control.
• To evaluate the long-term retention of learned skin temperature control.

Main Methods:

• Sixty female subjects were divided into six groups receiving varying combinations of instructions (response-specific, thermal suggestions, rest) and biofeedback.
• Training involved five daily sessions, followed by two-week and one-week follow-up sessions.

Main Results:

• Groups receiving feedback with response-specific instructions or thermal suggestions, and the group with thermal suggestions without feedback, demonstrated significant digital skin temperature increases.
• These groups maintained their ability to control skin temperature at both 1-week and 2-week follow-ups.
• Other conditions showed no significant learning or retention of temperature control.

Conclusions:

• Response-specific instructions and thermal suggestions, particularly when combined with biofeedback, are effective in teaching skin temperature self-control.
• Learned skin temperature control can be retained for at least two weeks.
• The type of instruction and presence of biofeedback are critical factors in successful temperature self-regulation training.
