Meditation Research
The German weekly news magazine Focus had a cover story last Saturday on mental training and the latest findings in science about stress and burn-out. Meditation and mindfulness turn out to be effective tools against stress and burn-out symptoms. Very successful in the US is MBSR: Mindfulness Based Stress Reduction, which is offered as an 8 week course in 250 clinics all over the country. It has been developed by the Center for Mindfulness (CFM) at the University of Massachusetts Medical School: “The central focus of the Clinic is intensive training in mindfulness meditation and its integration into the challenges/adventures of everyday life.” Jon Kabat-Zinn invented this methodology and made proof that it is medically effective. It is based on an ancient Buddhist meditation technique: Vipassana Meditation which is also called insight-meditation and aims at self transformation through self observation. There is more and more evidence from research on the effects of meditation. Psychologist Richard Davidson worked closely with the Dalai Lama who connected him to Tibetan monks with whom he could do his medical studies of the brain as it relates to meditation. The outcome of his work can be read here: Mental Training Affects Distribution of Limited Brain Resources and Alterations in Brain and Immune Function Produced by Mindfulness Meditation. Sara Lazar at Harvard University found out that meditation influences cortical thickness of people who have meditated for a long time: “Brain regions associated with attention, interoception and sensory processing were thicker in meditation participants than matched controls, including the prefrontal cortex and right anterior insula. Between-group differences in prefrontal cortical thickness were most pronounced in older participants, suggesting that meditation might offset age-related cortical thinning.” In my previous blog entry I mentioned that meditation is still regarded as strange by many in our Western world. Although there have been already some meditation courses for executives in the past this type of mental training remains outside the corporate world. Through the type of research mentioned here this might change over time. We see more and more adoption of Eastern philosophy in our Western world. Tools from Buddhism, Yoga, Ayurveda, chinese medical treatment... the list is long. Regularly there are features in the press or television about any one of these techniques. A probably more philosophical question is why we do not stick with our own techniques, our medicine, the belief in our religion? Apparently these are not able to fill a gap that has occured with the ever accelerating pace of the world around us which made us loose contact to our own roots, traditions, ancient wisdoms...??

Permit this one comment on meditation. A primary emphasis in meditation is on the reduction of rumination, but non-conscious distractive events are also implicitly reduced but have never been separately controlled in the literature of meditation. If they were, it would engender a new procedure that would could produce many of the benefits of mindfulness without the control of rumination.
The following argument and procedure is derived from an article in the International Journal of Stress Management in 2006.
____________
Rest in Peace (and Quiet)
In the literature of stress, stress is commonly attributed to a monolithic ‘flight or fight’ reaction that accounts for all attributes of the stress response, from fear and anxiety to the tension that is elicited in a distractive day. Yet for minor or small scale choices or distractions, this ‘stress’ response begins with merely the slight yet sustained activation of low threshold or Type 1 muscular fibers. These muscles are activated easily and rapidly, deactivate slowly, and when sustained quickly fail and cause pain and exhaustion. (This is why at the end of a distraction filled working day we commonly report not fear or anxiety, but merely a state of exhaustion) This activation pattern does not entail fear or anger and is generally not reported as anxiety. Because of the neuro-muscular characteristics of this type of muscular activity, reducing the salience or frequency of distractive events is not enough to disengage this sustained or tonic tension. Distractions instead must be totally eliminated for a sustained period of time, and this is what is implicitly done in meditative practices. The question, yet unanswered, is what is the relative role of rumination and distraction in the maintenance of these low level stressors.
The Cinderella Effect
A common truism is that distractions not only cause us to get tense and remain tense during the day, but that tension ‘builds’ until we are sore and exhausted. However, the neuro-muscular processes behind this event are not widely known. Named after the fairy tale character who was first to awake and last to sleep, this ‘Cinderella Effect’ represents the fact that slight but continuous distractions (e.g. the continuous choice opportunities of surfing the internet or accessing email instead of working) elicit the continuous activation of low threshold units (also called Type 1, slow twitch, or Cinderella fibers) of the striated musculature, which unabated will lead to their failure and the successive recruitment of other muscular groups to take up the slack. The result is pain, exhaustion, and often a literal pain in the neck. (To elicit a similar result, try lightly clenching your fist for a minute or so.) In addition, as the name Cinderella underscores, this muscular activity does not immediately cease when distractions cease, and is sustained even when we take a break or rest.
Thus, even slight or intermittent distractions will elicit sustained or ‘tonic’ muscular tension, and usually to harmful and painful effect. It follows logically that only a radical and sustained reduction in distraction can result in a totally relaxed state. Thus, to be relaxed, a reduction in distractive choices is not enough, distraction must instead be totally eliminated or deferred, and that is what meditative practices implicitly do but ironically never explicitly concede. The problem is that meditation also entails a radical reduction in rumination as well as distraction, and the emphasis in meditative disciplines on the control of rumination obscures the distinctive influence of distraction in maintaining tense or anxious states. (Indeed, the respective roles of rumination and distraction have never been separately studied in the scientific literature on meditation.) However, if distraction and only distraction can be monitored and avoided in the many environments that are stressful primarily because of distraction, then one can achieve the means to be relaxed, even if the level of rumination is not altered. Thus one can learn to become relaxed even in workaday environments.
The Cinderella Method
The procedure:
First: Take a mental or physical inventory of all the minor unessential judgments in a working day that would entail minor avoidable gain/loss. These 'distractions' included doing one's work vs. reading the newspaper, watching TV, chatting on the phone, internet surfing, or other diversions. This provides a comparative or base rate to which to compare future behavior, and trains you to notice or attend to distractive choices.
Secondly: Set aside fixed times during the day (e.g. 8-9 am, 1-2pm) when you will completely avoid these choices. Then simply perform your rationally considered behavior (i.e., your work), or if not, just sit.
That's it.
By continuously eliminating these distractive choices from major portions of the day, you can still anticipate and be aware of them, but you cannot be stressed by choosing between them. By deferring irreconcilable choices, tension falls, relaxation occurs, and you can go about your day more relaxed, more alert, more productive, and without the painful regret that occurs from a day misspent. Finally, by providing a feedback function to train attention and to compare behavior across days, you can compare corresponding emotional behavior (i.e., tension) across behavior or 'trials', demonstrate the efficacy of the procedure, and be reinforced for the overall effort by that feedback.
What the Cinderella Method Does
The Cinderella Method is essentially a method of exercising a control over tension in its often initial form as a subliminal behavior that escapes conscious awareness. This method allows one to sustain a natural or homeostatic resting state that otherwise is disrupted in even a slightly distractive environment. Since for small distractions the proprioceptive stimuli which alert one to tension only indicate the presence of tension after tension has been sustained for some time, the isolation and control of the discriminative stimuli that are correlated with the initiation of slight or minor tension allow for tension to be avoided before its sustained occurrence taxes the musculature and autonomic nervous system. Conversely, the method also trains one to mentally recreate or ‘learn’ the proprioceptive stimuli associated with relaxation, and thus be able to ‘voluntarily’ induce relaxation. Since relaxation as a voluntary response (actually, what is learned is the inhibition of tension, since relaxation is not a response but is technically the non-activity of the musculature) is incompatible with tension, it will also mitigate tension caused by distraction and rumination even when both are not avoided.
Finally, the Cinderella Method sharply contrasts with prevalent stress control procedures, which emphasize the modification and control through psychotherapy and other means large scale or molar distractions or problems, such as domestic or other workaday difficulties and the rumination they entail. The Cinderella method is based on the premise that stress is predominantly caused by small scale or molecular problems or distractions that in contrast to rumination are far more frequent yet are more easily controlled. Because control is easy, time consuming therapeutic intervention is not required.
