Effects of expectancy on physiological responsivity in novice meditators
Biological Psychology
|September 1, 1985
Summary
First-time meditation may reduce physiological arousal, including heart rate and blood pressure. Positive expectations about meditation further lowered these physiological responses in novice meditators.
Area of Science:
- Psychophysiology
- Mind-Body Medicine
Background:
- Understanding the physiological effects of meditation is crucial for its therapeutic applications.
- Novice meditators' responses are key to differentiating meditation effects from expectancy effects.
Purpose of the Study:
- To investigate the psychophysiological effects of meditation in non-meditators.
- To examine the influence of positive expectations on meditation-induced physiological changes.
Main Methods:
- Forty female non-meditators participated in a within-subjects 'abab' design, alternating meditation and rest periods.
- Continuous monitoring of seven physiological measures, including blood pressure, heart rate, skin conductance, and skin temperature.
- Experimental cells controlled for order and expectation effects.
Main Results:
- Meditation was associated with marginally lower arousal in systolic blood pressure, heart rate, skin conductance level, and digital skin temperature compared to rest.
- Positive expectations significantly reduced diastolic and systolic blood pressure, heart rate, and skin conductance level during meditation.
Conclusions:
- Meditation may induce mild psychophysiological relaxation in novices.
- Expectancy plays a significant role in the physiological outcomes of meditation for beginners.
