Conceptual models and functions of meditation in psychotherapy

Although meditation is increasingly being employed as an adjunct in psychotherapy, there has been practically no comprehensive evaluation of its usefulness in this respect. This paper seeks to address this issue through conceptual models of the meditation experience. It is concluded that meditation practice may be associated with the acquisition of some useful skills (e.g., focused attention), that practice may be physiologically relaxing, that meditation may decrease anxiety, insomnia and drug usage, while enhancing hypnotic induction and self-actualization. There is still no compelling evidence, however, that meditation practice is associated with unique state effects compared with other relaxational procedures. Those who appear to benefit most from meditation appear to be those who present with milder disorders. The clinical value of meditation, therefore, appears to be limited. Furthermore, the long-term objectives of meditation are not in general congruent with those of mainstream psychotherapy, as they go beyond therapeutic gain in the clinical sense.     

Mindfulness meditation and relaxation training increases time sensitivity

Two experiments examined the effect of mindfulness meditation and relaxation on time perception using a temporal bisection task. In Experiment 1, the participants performed a temporal task before and after exercises of mindfulness meditation or relaxation. In Experiment 2, the procedure was similar than that used in Experiment 1, except that the participants were trained to mediate or relax every day over a period of several weeks. The results showed that mindfulness meditation exercises increased sensitivity to time and lengthened perceived time. However, this temporal improvement with meditation exercises was primarily observed in the experienced meditators. Our results also showed the experienced meditators were less anxious than the novice participants, and that the sensitivity to time increased when the level of anxiety decreased. Our results were explained by the practice of mindfulness technique that had developed individuals’ abilities in devoting more attention resources to temporal information processing.     

The use of bio-feedback in meditation technique: An innovative combination in psychotherapy

Conclusion The transistorized GSR apparatus is a convenient bio-feedback tool for monitoring the level of anxiety in a patient and for teaching him a simplified and expedient technique of meditation. Furthermore, once a patient attains a state of meditative relaxation, he becomes instantly aware of thoughts and associations that are conflict provoking and tension-building, by the fluctuations in the tone of the GSR. The therapist also becomes simultaneously aware of the significant areas of the patient's psycho-dynamics that need probing. This happens even when he is not verbalizing these thoughts. The therapeutic process is thereby expedited. Where the aim is symptom removal by desensitization, the GSR apparatus is helpful in promoting and measuring relaxation and in determining the subject's reactions to the anxiety-producing imagery used in this procedure.In short, used skillfully, this electronic device can be a valuable feedback instrument in the hands of a competent therapist.     

A controlled comparison of thermal biofeedback and relaxation training in the treatment of essential hypertension: II. Effects on cardiovascular reactivity

In the course of conducting a controlled comparison of progressive muscle relaxation and thermal biofeedback as possible substitutes for second-stage (sympatholytic) antihypertensive medications, we measured reactivity (heart rate, systolic blood pressure, and diastolic blood pressure) to three different stressors (mental arithmetic, cold pressor, and negative mental imagery) before and after treatment and drug withdrawal. Neither treatment was consistently effective in reducing reactivity across a variety of stressors. Relaxation led to more reductions in some aspect of reactivity than did biofeedback. The modest level of reductions in reactivity were seen more for mental arithmetic and systolic blood pressure.     

Comparative effectiveness of patterned biofeedback vs meditation training on EMG and skin temperature changes

This study examined whether a low arousal, relaxation pattern of frontalis EMG decreases and peripheral skin temperature increases could be attained more effectively through biofeedback or meditation training. Thirty female subjects, ranging in age from 21 to 59, were randomly assigned to one of three groups: patterned biofeedback, clinically standardized meditation or control. Prior to training, subjects were administered the EPI. Each subject was seen weekly for seven sessions. Subjective experiences and time spent practising at home were also recorded. Repeated measures ANCOVA's performed on the EMG and skin temperature means indicated that the meditation group showed significantly lower EMG levels at the end of treatment than the control group. No group had significant temperature increases nor were there any significant differences in practice time. The biofeedback group had difficulty in patterning the two feedback signals simultaneously. Extraverts in the control group had the highest EMG levels. The most positive subjective reports came from subjects in the meditation group. Meditation offers a viable alternative as a relaxation procedure, requiring little time to learn and devoid of any performance criteria levels.     

Progressive relaxation and meditation : A study of psychophysiological and therapeutic differences between two techniques

Physiological and self-report data were collected on anxious subjects who participated in a study comparing progressive relaxation, meditation and a waiting-list control. The data provide some support for the Schwartz, Davidson and Goleman (1978) hypothesis of specific effects for different relaxation procedures, superimposed upon a generalized relaxation response. The similarities between techniques, however, were greater than the differences, both on physiological and self-report measures. Both techniques generated positive expectancies and produced decreases in a variety of self-reported symptoms and on EMG: but no skin conductance or frontal EEG effects were observed. Progressive relaxation produced bigger decreases in forearm EMG responsiveness to stressful stimulation and a generally more powerful therapeutic effect than meditation. Meditation produced greater cardiac orienting responses to stressful stimuli, greater absorption in the task and better motivation to practice than progressive relaxation; but it also produced more reports of increased transient anxiety. We found no significant differences between conditions in the therapeutic expectancies they generated. The clinical implications of these findings are discussed.     

EMG biofeedback training, relaxation training, and placebo for the relief of chronic back pain

24 patients with chronic low back pain were randomly assigned to three treatment conditions: EMG biofeedback, relaxation training, and a placebo condition. Patients were seen for eight sessions and were evaluated before Session 1 and after Session 8. Eight analyses of covariance which were adjusted for age and pretest scores were computed on the final scores to find which variables could detect significant difference between treatments. Age was included as a covariate because the differences in age between conditions were significant. Four variables with significant and nearly significant differences were chosen for analysis. The second set of analyses identified the nature of the differences among the three conditions. These included a priori planned comparisons among conditions, and paired t tests. Relaxation-trained subjects were significantly superior to subjects in the placebo condition, in decreasing pain during the function test, increasing relaxation, and decreasing Upper Trapezius EMG. They were superior to EMG Biofeedback training in increasing reported activity. Both Relaxation and EMG trained subjects were able to reduce Upper Trapezius EMG by Session 8. Relaxation-trained subjects showed significant change on eight of the 14 possible comparisons for each treatment condition. EMG biofeedback training showed significant favorable results in only one condition; the placebo condition showed no significant results. Relaxation training gave better results in reducing EMG and pain, and in increasing relaxation and activity than either EMG biofeedback alone or a placebo condition.     

Effects of progressive relaxation and meditation on cognitive and somatic manifestations of daily stress

Meditation and progressive relaxation were compared with a self-monitoring control as treatments for symptoms of stress. Subjects were recruited from advertisements in local newspapers and received five sessions of training. All subjects self-monitored stress symptoms throughout the study and had their behavior rated weekly by a spouse/roommate. The progressive relaxation and meditation treatments resulted in a significant reduction of stress symptomatology over time. Little evidence was generated for differential effects of treatments.     

Physiological changes after biofeedback and relaxation training for multiple-pain tension-headache patients

This paper is concerned with the psychophysiology of "muscle-contraction" headaches in a group of Compensation patients suffering from multiple pain problems in addition to headaches. A total of 55 of these patients were divided into 4 groups which received frontalis EMG biofeedback, relaxation training, combined biofeedback-relaxation training, or no treatment. Differences were observed among the 3 experimental treatments and the control group with respect to headache changes, but there were no differences among groups with respect to the changes observed in four underlying physiological responses as a function of time or practice. While the subjects who showed the largest changes in headache characteristics were those who exhibited the largest decreases in frontalis EMG, these were also the subjects whose initial frontalis EMG levels were the highest. It is concluded that, in keeping with a growing literature, the link between frontalis EMG and "muscle-contraction" headaches is a tenuous one and that the changes brought about in headache symptomatology through biofeedback or relaxation training are most likely attributable to a generalization of feelings of mastery over the environment or of self-efficacy brought about in the subjects through apparent success at the task.     

Consciousness,self-consciousness,and meditation

Many spiritual traditions employ certain mental techniques (meditation) which consist in inhibiting mental activity whilst nonetheless remaining fully conscious, which is supposed to lead to a realisation of one’s own true nature prior to habitual self-substantialisation. In this paper I propose that this practice can be understood as a special means of becoming aware of consciousness itself as such. To explain this claim I conduct some phenomenologically oriented considerations about the nature of consciousness qua presence and the problem of self-presence of this presence.
