Improve Depression, Anxiety, and Stress Symptoms and Lower Rumination with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness-based practices have proved to be helpful in promoting mental well-being, especially by reducing the symptoms of depression and anxiety in various populations.” – Han Ding

 

Over the last several decades, research and anecdotal experiences have accumulated an impressive evidential case that the development of mindfulness has positive benefits for the individual’s mental, physical, and spiritual life. Mindfulness appears to be beneficial both for healthy people and for people suffering from a myriad of mental and physical illnesses. It appears to be beneficial across ages, from children to the elderly. And it appears to be beneficial across genders, personalities, race, and ethnicity. There is a vast array of techniques for the development of mindfulness that include a variety of forms of meditation, yoga, mindful movements, contemplative prayer, and combinations of practices.

 

Mindfulness-Based Cognitive Therapy (MBCT)  was specifically developed to treat depression. MBCT involves mindfulness training, containing sitting, walking and body scan meditations, and cognitive therapy That is designed to alter how the patient relates to the thought processes that often underlie and exacerbate psychological symptoms. Another therapeutic technique is Compassion Focused Therapy (CFT). “It seeks to help individuals develop compassion for self and others . . . and includes cultivating mindfulness and body awareness. . . . MBCT puts the primary focus on cultivating mindfulness whereas CFT puts it on cultivating compassion toward self and others.”

 

In today’s Research News article “Effects of Mindfulness Based Cognitive Therapy (MBCT) and Compassion Focused Therapy (CFT) on Symptom Change, Mindfulness, Self-Compassion, and Rumination in Clients With Depression, Anxiety, and Stress.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.01099/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_999212_69_Psycho_20190528_arts_A), Frostadottir and colleagues recruited patients at a 4-week inpatient rehab clinic who were suffering from mild to moderate depression, anxiety, or stress symptoms. They were assigned to receive twice a week 2 hour sessions for 4 weeks of either Mindfulness-Based Cognitive Therapy (MBCT), Compassion Focused Therapy (CFT), or a wait-list control condition. They were measured before and after treatment and one month later for mindfulness, self-compassion, rumination, anxiety, depression, and stress.

 

They found that in comparison to baseline and the wait-list control group, the groups that received either Mindfulness-Based Cognitive Therapy (MBCT) or Compassion Focused Therapy (CFT) demonstrated significantly lower levels of rumination, anxiety, depression, and stress and significantly higher levels of mindfulness and self-compassion. These improvements were still present and significant at the 1-month follow-up. Those participants who were high in rumination had significantly higher posttreatment mindfulness for the MBCT group while CFT produced higher mindfulness regardless of rumination.

 

Since there wasn’t an active control group placebo effects and experimenter bias are possible alternative explanations for the changes. Other research however has routinely demonstrated that mindfulness training produces lower levels of anxiety, depression, stress symptoms, and rumination and higher levels of self-compassion and mindfulness. Hence, it is likely that the benefits seen in the present study were due to the interventions and not to artifact.

 

The results suggest that both Mindfulness-Based Cognitive Therapy (MBCT) and Compassion Focused Therapy (CFT) are beneficial for the mental health of patients with mild to moderate depression, anxiety, or stress symptoms. Since, both therapies train mindfulness and both successfully increased mindfulness, it would appear that mindfulness training in general is beneficial to patients with mild to moderate mental health issues. So, the present study adds to the large literature demonstrating the benefits of mindfulness for psychological health.

 

So, improve depression, anxiety, and stress symptoms and lower rumination with mindfulness.

 

“If you have unproductive worries. You might think ‘I’m late, I might lose my job if I don’t get there on time, and it will be a disaster!’ Mindfulness teaches you to recognize, ‘Oh, there’s that thought again. I’ve been here before. But it’s just that—a thought, and not a part of my core self,’” – Elizabeth Hoge

Study Summary

 

Frostadottir AD and Dorjee D (2019) Effects of Mindfulness Based Cognitive Therapy (MBCT) and Compassion Focused Therapy (CFT) on Symptom Change, Mindfulness, Self-Compassion, and Rumination in Clients With Depression, Anxiety, and Stress. Front. Psychol. 10:1099. doi: 10.3389/fpsyg.2019.01099

 

Objectives: Over the past decade there has been an increasing interest in exploring self-compassion as a related and complementary construct to mindfulness. Increases in self-compassion may predict clinical outcomes after MBCT and cultivation of compassion toward self and others is central to CFT. This pilot study compared the impact of MBCT applying implicit self-compassion instructions and CFT employing explicit self-compassion instructions on symptom change, mindfulness, self-compassion, and rumination.

Method: This non-randomized wait-list controlled study (N = 58) with two intervention arms (MBCT N = 20, CFT N = 18, Control N = 20) assessed the outcomes of clients with depression, anxiety, and stress symptoms from before to after the interventions and at one month follow up (MBCT N = 17, CFT N = 13, Control N = 13).

Results: Both treatments resulted in significant increases in mindfulness and self-compassion and decreases in rumination, depression, anxiety, and stress. Furthermore, MBCT enhanced mindfulness for people who were initially high in rumination, whereas CFT enhanced mindfulness across the board.

Conclusion: The findings suggest that both MBCT and CFT, and hence implicit or explicit self-compassion instructions, produce similar clinical outcomes with CFT enhancing mindfulness regardless of client’s rumination level.

Sexual Arousal and Mindfulness are Linked in Complex Ways

Sexual Arousal and Mindfulness are Linked in Complex Ways

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation” training — which teaches how to bring one’s thoughts into the present moment — can quiet the mental chatter that prevents these women from fully feeling sexual stimuli.” – Gina Silverstein

 

Problems with sex are very common, but, with the exception of male erectile dysfunction, driven by the pharmaceutical industry, it is rarely discussed and there is little research. While research suggests that sexual dysfunction is common, it is a topic that many people are hesitant or embarrassed to discuss. Women suffer from sexual dysfunction more than men with 43% of women and 31% of men reporting some degree of difficulty. These problems have major impacts on people’s lives and deserve greater research attention.

 

Problems with sex with women can involve reduced sex drive, difficulty becoming aroused, vaginal dryness, lack of orgasm and decreased sexual satisfaction. Sexual function in women involves many different systems in the body, including physical, psychological and hormonal factors. So, although, female sexual dysfunction is often caused by physical/medical problems, it is also frequently due to psychological issues. This implies that it many cases female sexual problems may be treated with therapies that are effective in working with psychological problems.

 

Mindfulness trainings have been shown to improve a variety of psychological issues including emotion regulation, stress responses, trauma, fear and worry, anxiety, and depression, and self-esteem. Mindfulness training has also been found useful in treating sexual problems. But there is little empirical research. So, it makes sense to further investigate the relationship of mindfulness with female sexual arousal.

 

In today’s Research News article “Subjective and Oxytocinergic Responses to Mindfulness Are Associated With Subjective and Oxytocinergic Responses to Sexual Arousal.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.01101/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_999212_69_Psycho_20190528_arts_A), Dickinson and colleagues recruited women between the ages of 20 to 35 for a study on sexuality and stress hormones and measured them for mindfulness. They watched landscape photographs and rated their liking of the photographs and then provided salivary samples to assess oxytocin and cortisol. Oxytocin levels are a marker of sexual arousal. They then listened to 1.5-minute stories that were either neutral or erotic and provided salivary samples. They also rated their sexual arousal after each story. They then performed a breath focused meditation for 15 minutes and provided a third salivary sample. After a 15-minute quiet period they provided a fourth sample.

 

They found that the higher the women scored on mindfulness, particularly the describing facet, the higher their levels of reported arousal in response to the erotic stories. They also found that oxytocin levels did not significantly increase in response to the erotic stories, decreased significantly in response to mindful breathing, and increased during recovery. They further found that women high in the mindfulness facet of non-judging internal experience and women who were quicker in detecting mind wandering during meditation had significantly greater decreases in oxytocin during meditation. In addition, women who were quick in detecting mind wandering and women who reported large increases in sexual arousal while listening to the erotic stories had greater decreases in oxytocin while meditating.

 

These are complex results. They suggest that in women mindfulness, subjective sexual arousal, and endocrine markers of sexual arousal are all linked in complex ways. They also suggest that women who are high in mindfulness are more sexually responsive to erotic stimuli. This may suggest that mindfulness training may be effective in increasing women’s ability to be sexually aroused. Future research should investigate whether mindfulness training may be an effective treatment for women who have difficulty with sexual arousal.

 

“among women who have sexual difficulties, mindfulness not only improves their desire but improves their overall sexual satisfaction, too.” – Tracy Clark-Flory

Study Summary

 

Dickenson JA, Alley J and Diamond LM (2019) Subjective and Oxytocinergic Responses to Mindfulness Are Associated With Subjective and Oxytocinergic Responses to Sexual Arousal. Front. Psychol. 10:1101. doi: 10.3389/fpsyg.2019.01101

 

Mindfulness – the ability to pay attention, on purpose, without judgment, and in the present moment – has consistently been shown to enhance women’s sexual arousal. As a first step toward understanding potential neuroendocrine underpinnings of mindfulness and sexual arousal, we examined whether individual differences in subjective and neuroendocrine (i.e., oxytocin) responses to mindful breathing were associated with individual differences in subjective and neuroendocrine responses to sexual arousal. To achieve this aim, 61 lesbian, bisexual, and heterosexual women completed a questionnaire assessing dispositional mindfulness, underwent an arousal task while continuously rating their sexual arousal and a mindful breathing task, after which participants reported on their ability to detect attentional shifts, and provided salivary samples after each assessment. Results indicated that women who were quicker to detect attentional shifts and women who reported greater sexual arousability reported larger changes (decreases) in oxytocin in response to mindful breathing and were the only women to report increases in oxytocin in response to the sexual arousal induction. Results further indicated that individuals who report greater subjective responsiveness to mindfulness and sexual arousal appear to have an oxytocinergic system that is also more responsive to both arousal and to mindfulness. These results make a significant contribution to our understanding of the role of attentional processes in sexual arousal, and warrant future examination of oxytocin as a potential neuroendocrine mechanism underlying the link between mindfulness and sexual arousal.

Improve Attention Deficit Hyperactivity Disorder (ADHD) in Adults with Mindfulness

Improve Attention Deficit Hyperactivity Disorder (ADHD) in Adults with Mindfulness

 

By John M. de Castro, Ph.D.

 

“Mindful awareness isn’t about staying with the breath, but about returning to the breath. That’s what enhances your ability to focus. And this emphasis on re-shifting your attention, of outwitting the mind’s natural tendency to wander, is what makes this technique especially helpful to someone who has ADHD.” – Carl Sherman

 

Attention Deficit Hyperactivity Disorder (ADHD) is most commonly found in children, but for about half it persists into adulthood. It’s estimated that about 5% of the adult population has ADHD. Hence, this is a very large problem that can produce inattention, impulsivity, hyperactivity, and emotional issues, and reduce quality of life. The most common treatment is drugs, like methylphenidate, Ritalin, which helps reducing symptoms in about 30% of the people with ADHD. Unfortunately, the effectiveness of the drugs appears to be markedly reduced after the first year. In addition, the drugs often have troublesome side effects, can be addictive, and can readily be abused. So, drugs, at present, do not appear to be a good solution, only affecting some, only for a short time, and with unwanted side effects.

 

There are indications that mindfulness training may be an effective treatment for ADHD. It makes sense that it should be, as the skills and abilities strengthened by mindfulness training are identical to those that are defective in ADHD,  attention, impulse control, executive function, emotion control, and mood improvement. In addition, unlike drugs, it is a relatively safe intervention that has minimal troublesome side effects. Since mindfulness is so promising as a treatment, it is important to step back and summarize what has been learned in the scientific research of the effectiveness of mindfulness training for ADHD. Most of the research has been with children. But ADHD often persists into adulthood. So, it is important to take a look at the published research on the effectiveness of mindfulness training for ADHD in adults.

 

In today’s Research News article “Behavioral and Cognitive Impacts of Mindfulness-Based Interventions on Adults with Attention-Deficit Hyperactivity Disorder: A Systematic Review.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6476147/), Poissant and colleagues review and summarize the published research studies on the effectiveness of Mindfulness based interventions on the symptoms of ADHD in adults.

 

They found 13 published studies with a total of 753 participants. All 13 studies reported significant improvements in Attention Deficit Hyperactivity Disorder (ADHD) symptoms following mindfulness training and the improvements were maintained six months after the end of training. The participants had significant improvements in higher level thinking (cognitive function) and emotion regulation.

 

They also report that the quality of the research designs used were fairly weak and hence caution must be exercised in reaching definitive conclusions. Better controlled research studies are needed. Nevertheless the published research studies consistently found that mindfulness-based interventions produced improvements in the symptoms of adults with Attention Deficit Hyperactivity Disorder (ADHD).

 

So, improve attention deficit hyperactivity disorder (ADHD) in adults with mindfulness.

 

“mindfulness practice can help us pay attention better, resist distractions, be less impulsive, remember what we are doing in the moment, and regulate our own emotions, it is helpful whether we have ADHD or not. But it holds special interest for those with ADHD.” – Mindfully ADD

Abstract

Mindfulness-based interventions (MBIs) are becoming increasingly popular as treatments for physical and psychological problems. Recently, several studies have suggested that MBIs may also be effective in reducing symptoms of attention-deficit hyperactivity disorder (ADHD). Most studies have examined the effectiveness in children, but there are now a sufficient number of individual treatment trials to consider a systematic review in adults. Majority of existing systematic reviews and meta-analyses only consider ADHD symptoms as an outcome, and most of them do not fully report potential biases of included studies, thus limiting considerably their conclusions. This is an important facet because some studies could be found ineligible to be included in future analysis due to their low quality. In this systematic review, we followed the PRISMA/PICO criteria and we thoroughly assessed the risks of bias for each of the selected studies according to Cochrane guidelines. We searched the available literature concerning MBIs in adult participants with ADHD using PsycINFO, PubMed, Scopus, and ERIC databases. In total, 13 studies conducted with 753 adults (mean age of 35.1 years) were identified as eligible. Potential moderators such as participants’ age, ADHD subtypes, medication status, comorbidity, intervention length, mindfulness techniques, homework amount, and training of therapists were carefully described. Aside from measuring the symptoms of ADHD, outcome measures were categorized into executive/cognitive functioning, emotional disturbances, quality of life, mindfulness, and grade point average at school. According to presented descriptive results, all the studies (100%) showed improvement of ADHD symptoms. In addition, mindfulness meditation training improves some aspects of executive function and emotion dysregulation. Although these are promising findings to support treatment efficacy of MBIs for ADHD, various biases such as absence of randomization and lack of a control group may affect the actual clinical value and implications of the studies. Moreover, the relatively low quality of selection and performance criteria in several studies, as well as relatively high attrition bias across studies, call for caution before considering conducting further analysis.

Reduce Injurious Falls in the Elderly with Tai Chi

Reduce Injurious Falls in the Elderly with Tai Chi

 

By John M. de Castro, Ph.D.

 

“What is fascinating is that the fear of falling often results in more falls; hence, confidence in “not falling” will help to reduce falls. With regular practice, tai chi improves balance by strengthening muscles and co-ordination; at the same time, it strengthens the mind, thereby improving calmness and confidence in not falling. Thus, both physically and mentally, tai chi is an extremely effective exercise for fall prevention.” – Paul Lam

 

The process of aging affects every aspect of the physical and cognitive domains. Every system in the body deteriorates including motor function with a decline in strength, flexibility, and balance. Impaired balance is a particular problem as it can lead to falls. In the U.S. one third of people over 65 fall each year and 2.5 million are treated in emergency rooms for injuries produced by falls. About 1% of falls result in deaths making it the leading cause of death due to injury among the elderly.

 

Falls, with or without injury, also carry a heavy quality of life impact. A growing number of older adults, fear falling and, as a result, limit their activities and social engagements. This can result in further physical decline, depression, social isolation, and feelings of helplessness. It is obviously important to discover methods to improve balance and decrease the number of falls in the elderly.

 

Tai Chi training is designed to enhance and regulate the functional activities of the body through regulated breathing, mindful concentration, and gentle movements. It includes balance training and has been shown to improve balance and coordination. Indeed, Tai Chi training has been shown to reduce the frequency of falls in the elderly. It is not known, however, if Tai Chi training is better or worse than other exercises for reducing falls in the elderly.

 

In today’s Research News article “Effectiveness of Tai Ji Quan vs Multimodal and Stretching Exercise Interventions for Reducing Injurious Falls in Older Adults at High Risk of Falling: Follow-up Analysis of a Randomized Clinical Trial.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6484587/), Harmer and colleagues recruited elderly individuals (70 years of age and older) who had impaired mobility and who had experienced falls in the last year. They were randomly assigned to either to twice weekly, 1-hour, sessions, for 24 weeks of Tai Chi practice, multimodal exercise, or stretching exercises. Multimodal exercises consisted of “a mix of aerobic conditioning and strength, balance, and flexibility activities.” They were measured before, after, and 3 and 6 months after the interventions for falls, and the “number of fall-related emergency department visits and hospitalizations.”

 

They found that at 6 and 12 months, the Tai Chi  groups had significantly fewer injurious falls both moderately serious and serious than the stretching group and significantly fewer than the multimodal exercise group at 6 months. The multimodal exercise group also had significantly fewer serious falls than the stretching group at 12 months. At the 12 month point the Tai Chi group had significantly fewer emergency department visits and hospitalizations than the multimodal exercise group and the stretching group. The multimodal exercise group had significantly fewer emergency department visits than the stretching group

 

The results demonstrate that although multimodal exercise is beneficial for the elderly in reducing injurious falls, practicing Tai Chi  was significantly more beneficial; reducing injurious falls, emergency department visits and hospitalizations. Tai Chi  is gentle and safe, is appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion, is inexpensive to administer, can be performed in groups or alone, at home or in a facility, and can be quickly learned. In addition, it can be practiced in social groups. This can make it fun, improving the likelihood of long-term engagement in the practice. So, Tai Chi  practices would appear to be an excellent gentle practice to reduce injurious falls in aging individuals.

 

“Older adults at high-risk for falls are often physically inactive, thus practical and effective interventions are needed to reduce sedentary time and improve lower-body strength and balance,” – Matthew Smith

Key Points

Question

Is a therapeutically tailored tai ji quan intervention more effective than stretching exercise or a proven multimodal exercise intervention in decreasing injurious falls among community-dwelling older adults at high risk of falling?

Findings

In this follow-up analysis of a randomized clinical trial that included 670 older adults with a history of falls or impaired mobility, a therapeutic tai ji quan intervention, Tai Ji Quan: Moving for Better Balance, was significantly more effective for lowering the incidence of both moderate injurious falls compared with stretching exercise and serious injurious falls compared with stretching exercise and multimodal exercise.

Meaning

The therapeutically tailored tai ji quan training intervention proved to be more safe and effective than stretching or multimodal exercises in reducing the incidence of injurious falls in older adults at high risk of falling.

Abstract

Importance

Exercise has been shown to reduce injurious falls in older adults. Evidence, however, is lacking regarding the types of intervention that are most effective in preventing injurious falls among older adults at high risk of falling.

Objective

To determine the longer-term effectiveness of therapeutic tai ji quan intervention vs multimodal exercise and stretching exercise in decreasing injurious falls among older adults at high risk of falling.

Design, Setting, and Participants

This trial involves a prespecified analysis with the data analyzed by intent-to-treat. Follow-up analysis of a single-blind randomized trial conducted in community settings of 7 urban and suburban cities in Oregon from February 20, 2015, to September 15, 2018, compared a therapeutic tai ji quan intervention with multimodal exercise and stretching exercise. Eligible participants were community-dwelling adults aged at least 70 years who were considered by a clinician to be at high risk of falling because they had fallen during the preceding year or who had impaired mobility with scores higher than 13.5 seconds on the Timed Up & Go test. Participants were randomized to 1 of the 3 interventions and were assessed monthly after randomization for 12 months, encompassing a 6-month active intervention phase and a 6-month after intervention follow-up phase.

Interventions

The 3 group-based interventions were therapeutic tai ji quan (Tai Ji Quan: Moving for Better Balance [TJQMBB]), multimodal exercise, and stretching exercise, each implemented twice weekly in 60-minute sessions for 24 weeks.

Main Outcomes and Measures

Primary outcomes were the incidence of moderate and serious injurious falls at 12 months, measured as incidence rate ratios (IRRs).

Results

Of the 1147 persons screened, 670 (mean [SD] age, 77.7 [5.6] years; 436 women [65.1%]) were randomly assigned to 1 of 3 intervention groups: 224 persons in TJQMBB, 223 in multimodal exercise, and 223 in stretching exercise. At 12 months, the unadjusted IRR for moderate injurious falls was lower in the TJQMBB (IRR, 0.51; 95% CI, 0.35-0.74; P < .001) and multimodal exercise (IRR, 0.62; 95% CI, 0.42-0.89; P = .01) groups compared with the stretching exercise group. There was no difference between TJQMBB and multimodal exercise groups (IRR, 0.85; 95% CI, 0.58-1.25; P = .42). Both TJQMBB and multimodal exercise significantly reduced serious injurious falls (TJQMBB: IRR, 0.25 [95% CI, 0.13-0.48; P < .001]; multimodal: IRR, 0.56 [95% CI, 0.33-0.94; P = .03]) compared with stretching exercise. Use of TJQMBB was more effective than multimodal exercise (IRR, 0.47; 95% CI, 0.24-0.92; P = .03) in reducing serious injurious falls.

Conclusions and Relevance

For preventing injurious falls, including those that resulted in medical treatment, TJQMBB intervention was found to be superior to multimodal and stretching exercises for older adults at high risk of falling. The findings appear to strengthen the clinical use of TJQMBB as a single exercise intervention to prevent injurious falls in this population.

Reduce Anxiety with Acceptance and Commitment Therapy

Reduce Anxiety with Acceptance and Commitment Therapy

 

By John M. de Castro, Ph.D.

 

“Self-compassionate people tend to have lower levels of social anxiety—perhaps because self-compassion includes mindfulness, which soothes the stress associated with anxiety.” – Jill Suttie

 

It is a common human phenomenon that being in a social situation can be stressful and anxiety producing. Most people can deal with the anxiety and can become quite comfortable. But many do not cope well and the anxiety is overwhelming, causing the individual to withdraw. Social Anxiety Disorder (SAD) is characterized by a persistent, intense, and chronic fear of being watched and judged by others and feeling embarrassed or humiliated by their actions. This fear may be so severe that it interferes with work, school, and other activities and may negatively affect the person’s ability to form relationships.

 

Anxiety disorders have generally been treated with drugs. But there are considerable side effects and these drugs are often abused. There are a number of psychological therapies for anxiety. But, about 45% of the patients treated do not respond to the therapy. So, there is a need to develop alternative treatments. Recently, it has been found that mindfulness training can be effective for anxiety disorders including Social Anxiety Disorder (SAD). Mindfulness-Based Stress Reduction (MBSR) and also Cognitive Behavioral Therapy (CBT) have been shown to be effective in treating Social Anxiety Disorder (SAD).

 

A therapeutic technique that contains mindfulness training and Cognitive Behavioral Therapy (CBT) is Acceptance and Commitment Therapy (ACT). It is a mindfulness-based psychotherapy technique that is employs many of the techniques of Cognitive Behavioral Therapy (CBT). ACT focuses on the individual’s thoughts, feelings, and behavior and how they interact to impact their psychological and physical well-being. It then works to change thinking to alter the interaction and produce greater life satisfaction. ACT employs mindfulness practices to increase awareness and develop an attitude of acceptance and compassion in the presence of painful thoughts and feelings. ACT teaches individuals to “just notice”, accept and embrace private experiences and focus on behavioral responses that produce more desirable outcomes.

 

In today’s Research News article “The effectiveness of acceptance and commitment group therapy on social anxiety in female dormitory residents in Isfahan university of medical sciences.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6432841/), Toghiani and colleagues recruited female college students and randomly assigned them to receive 5-week, one 2-hour session per week, group Acceptance and Commitment Therapy (ACT) or to a no-treatment control group. Before the intervention and 2 months later the students were measured for social anxiety, performance anxiety and psychological flexibility.

 

They found that in comparison to baseline and the no-treatment control group, the students who received ACT had significantly reduced social anxiety, social avoidance, performance anxiety, and performance avoidance. These results must be interpreted cautiously as there was not an active control condition leaving open the possibility of placebo effects and experimenter bias effects. Nevertheless, the study suggests that ACT is an effective therapy to reduce anxiety in female college students with lasting effects.

 

So, reduce anxiety with Acceptance and Commitment Therapy.

 

“the art of mindfulness meditation practice. If you are suffering with the symptoms of social anxiety disorder (SAD), regular practice will eventually improve your self-concept and ability to handle negative emotions. You will also learn how to better respond to troubling thoughts and treat yourself with more compassion.” – Arlin Cuncic

Improve Sensory Discrimination with Alternate-Nostril Yoga Breathing

 

By John M. de Castro, Ph.D.

 

“alternate nostril breathing, has a long history in Ayurvedic medicine and yoga, where it’s thought to harmonize the two hemispheres of the brain, resulting in a balanced in physical, mental and emotional well-being.” – Paula Watkins

 

Yoga practice is becoming increasingly popular in the west, for good reason. It has documented benefits for the individual’s psychological and physical health and well-being. It has also been shown to have cognitive benefits, improving memory. Yoga, however, consists of a number of components including, poses, breathing exercises, meditation, concentration, and philosophy/ethics.  So, it is difficult to determine which facet or combination of facets of yoga are responsible for which benefit. Hence, it is important to begin to test each component in isolation to determine its effects.

 

Alternate nostril yoga breathing is a regulated breathing alternating between the left and right nostril that is commonly practiced in yoga. Breathing through each nostril is thought to affect its respective hemisphere in the brain producing differential effects. Recently, it has been shown to reduce blood pressure and increase vigilance and reduce perceived stress.

 

In today’s Research News article “Changes in Shape and Size Discrimination and State Anxiety After Alternate-Nostril Yoga Breathing and Breath Awareness in One Session Each.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6496972/), Telles and colleagues recruited healthy adult males with at least 3 months of yogic breathing practice. They each completed 3 sessions, alternate nostril breathing, breath awareness, and quiet sitting in counterbalanced orders. Each session consisted of three 5-minute practice periods separated by one minute. Before and after each session the participants competed measures of state and trait anxiety and completed a shape and size discrimination task involving inserting “50 coins and squares of different sizes and thickness into 5 slits of a wooden box, where each slit has been especially designed to allow a square or coin of a specific size and thickness to pass through it.”

 

They found that after the alternate nostril breathing session but not breath awareness or quiet sitting sessions there were significantly fewer error on the shape and size discrimination task. On the other hand, after the breath awareness or quiet sitting sessions but not the alternate nostril breathing session there were significantly lower levels of anxiety.

 

It would appear that alternate nostril breathing heightens awareness, increasing vigilance allowing for enhanced sensory discrimination ability while breath awareness and quiet sitting are calming reducing negative emotions. It’s interesting that different approaches to the breath have such large differences in their effects. This suggests that further research into the effects of the individual components of yoga practice may be a fruitful approach to understanding and potentially enhancing the benefits of yoga practice.

 

So, improve sensory discrimination with alternate-nostril yoga breathing.

 

“Alternate Nostril Breathing effectively reduces cortisol (stress) levels, increases mental focus, enhances immunity, and decreases depression and anxiety, with quick and lasting effects.” – Art of Living

Study Summary

 

Telles, S., Vishwakarma, B., Gupta, R. K., & Balkrishna, A. (2019). Changes in Shape and Size Discrimination and State Anxiety After Alternate-Nostril Yoga Breathing and Breath Awareness in One Session Each. Medical science monitor basic research, 25, 121–127. doi:10.12659/MSMBR.914956

 

Abstract

Background

Yoga breathing techniques like high-frequency yoga breathing (HFYB) and breath awareness (BAW) have been associated with improved performance in the shape and size discrimination task. A PubMed search of the literature revealed that alternate-nostril breathing has been shown to improve performance in attention tasks, but the effect on tactile perception has not been studied. Hence, the present study was designed to assess the immediate effects of alternate-nostril yoga breathing (ANYB) compared to breath awareness on shape and size discrimination and state anxiety.

Material/Methods

Fifty healthy male volunteers ages 20–50 years (group mean ±S.D., 28.4±8.2 years) were recruited. Each participant was assessed in 3 sessions conducted on 3 separate days at the same time of day. The 3 sessions were (i) alternate-nostril yoga breathing (ANYB), (ii) breath awareness (BAW), and (iii) quiet sitting (QS), and the sequence of the sessions was randomly allocated. The shape and size discrimination task and state anxiety were assessed before and after all 3 sessions. Repeated measures analysis of variance (RM-ANOVA) followed by post hoc tests for multiple comparisons, which were Bonferroni-adjusted, were performed to compare data before and after all 3 sessions using SPSS version 18.0.

Results

The errors scores in the shape and size discrimination task showed a significant reduction after the ANYB session (p<0.001). A significant reduction was found in the level of state anxiety after breath awareness (p<0.05) and quiet sitting sessions (p<0.001).

Conclusions

The present results suggest that ANYB: (i) improves performance in a task which requires perceptual sensitivity and focused attention, but (ii) does not reduce state anxiety following this task.

Alter the Brain to Deal with Stress with Meditation and Yoga

Alter the Brain to Deal with Stress with Meditation and Yoga

 

By John M. de Castro, Ph.D.

 

“Brain researchers have detected improvements in cognition and emotional well-being associated with meditation and yoga, as well as differences in how meditation and prayer affect the brain.” – Michaela Jarvis

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. One way that mindfulness practices may produce these benefits is by altering the brain. The nervous system is a dynamic entity, constantly changing and adapting to the environment. It will change size, activity, and connectivity in response to experience. These changes in the brain are called neuroplasticity. Over the last decade neuroscience has been studying the effects of contemplative practices on the brain and has identified neuroplastic changes in widespread areas. In other words, mindfulness practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits.

 

In today’s Research News article “Meditation and yoga practice are associated with smaller right amygdala volume: the Rotterdam study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6302143/), Gotink and colleagues utilized the data on participants in the longitudinal Rotterdam Study who were 45 years of age and older  at the time of recruitment and at the time of measurement had a mean age of 64 years. They were interviewed to determine if the practiced meditation and yoga and whether these practices improved their coping with stress. They were also measured for body size, blood pressure, blood fat, diabetes, smoking, alcohol use, stress, anxiety, and depression. In addition, their brains were scanned with Magnetic Resonance Imaging (MRI).

 

They found that practitioners of meditation and yoga reported higher stress levels than non-practitioners, but reported that the practice helped them cope with the stress. In addition, meditation practitioners had higher depression levels than non-practitioners. It is possible that people who are under high levels of stress or are depressed tend to engage in meditation and yoga practices to help cope with it.

 

They also report that the practitioners had smaller volumes of the brain structures right side amygdala and left hippocampus. In addition, over a five-year period the practitioners had a significant decrease in amygdala volume. The amygdala is associated with negative emotions and its smaller volume may suggest fewer or weaker negative emotions in practitioners.

 

This was a cross-sectional study and causation cannot be determined. It is possible that people with certain types of brains are more likely to practice. It will require a randomized controlled trial to determine what effects yoga and meditation practice may have on the psychological state and nervous system volumes.

 

Alter the brain to deal with stress with meditation and yoga.

 

“Studies show that yoga increases relaxation in the brain, improves areas of the brain that help us manage pain, and protects us against age-related decline. Together, these benefits begin to reveal the scientifically validated effects of yoga practice on brain health.” – Angela Wilson

Abstract

To determine the association between meditation and yoga practice, experienced stress, and amygdala and hippocampal volume in a large population-based study. This study was embedded within the population-based Rotterdam Study and included 3742 participants for cross-sectional association. Participants filled out a questionnaire assessing meditation practice, yoga practice, and experienced stress, and underwent a magnetic resonance scan of the brain. 2397 participants underwent multiple brain scans, and were assessed for structural change over time. Amygdala and hippocampal volumes were regions of interest, as these are structures that may be affected by meditation. Multivariable linear regression analysis and mixed linear models were performed adjusted for age, sex, educational level, intracranial volume, cardiovascular risk, anxiety, depression and stress. 15.7% of individuals participated in at least one form of practice. Those who performed meditation and yoga practices reported significantly more stress (mean difference 0.2 on a 1–5 scale, p < .001) and more depressive symptoms (mean difference 1.03 on CESD, p = .015). Partaking in meditation and yoga practices was associated with a significantly lower right amygdala volume (β = − 31.8 mm3, p = .005), and lower left hippocampus volume (β = − 75.3 mm3, p = .025). Repeated measurements using linear mixed models showed a significant effect over time on the right amygdala of practicing meditation and yoga (β = − 24.4 mm3, SE 11.3, p = .031). Partaking in meditation and yoga practice is associated with more experienced stress while it also helps cope with stress, and is associated with smaller right amygdala volume.

Mindful Independence Day

Mindful Independence Day

 

By John M. de Castro, Ph.D.

 

“If today is a celebration of freedom, I think we as a nation, as a people, have squandered an opportunity. We have sought outer freedoms and ignored inner freedoms. We have pursued these freedoms with scandal, exploitation, and domination. Today, instead, I urge you to consider inner freedom.” – Arnie Kozak

 

Virtually every country in the world sets aside one day each year to celebrate its independence. In the U.S. that day is July 4th. On this day the country’s citizens celebrate their freedom and independence and the fight that achieved it. It’s a pleasant holiday filled with patriotism, flags, parades, picnics, and fireworks displays. Although the founding of the great American democracy is something to celebrate, a mindful look at it produces a recognition that there are significant limitations on independence and freedom. We are nowhere near as free and independent as we think we are.

 

Independence from what? It’s certainly not from the imposition of government on the individual. July 4th only celebrates the changeover from government by the British monarchy to government by a more local political system. It’s certainly not independence from the imposition of laws and restrictions on the individual’s freedom. Perhaps there was a change of a few laws and regulations, but actually only a small number. It’s certainly not even the production of self-determination. In fact, the U.S. democracy was crafted and established by a few elite individuals and not by each individual in the country. In addition, democracy is rule by the majority, with the will of a significant number of people ignored. What we appear to be celebrating is the replacement of one system of control with another, perhaps better, system of control, but nevertheless a system of control; hardly independence.

 

Mindful reflection quickly produces an understanding that we’re never really independent. It’s certainly not even complete independence from another country. To this day the U.S. and the U.K. are very much dependent upon one another for trade of goods, ideas, culture, and mutual security. They’re locked together by treaties, cultural similarities, and close economic ties. The current political system that we’re celebrating is itself a recognition of how dependent upon one another we are. The system functions to set down the rules by which our relationships with one another are conducted. It’s there to insure orderly cooperation supposedly for the benefit of all participants.

 

Mindful reflection reveals that we’re not only dependent upon each other but we’re also dependent upon our environment, animate and inanimate. We’re dependent upon the air we breathe that is in turn dependent upon all other living organisms. We’re dependent upon the water we drink that is in turn dependent on global weather systems and solar evaporative power. We’re dependent upon the food we drink that is in turn dependent upon air, water, soil, and sun, and the farmers who grow it. In fact, we are so dependent upon everything and everybody that it may be more appropriate to be celebrating Dependence Day.

 

Well maybe then on July 4th we’re celebrating freedom and liberty. But, is any individual truly free. As the French philosopher Jean-Jacques Rousseau said “Man is born free: and everywhere else he is in chains. One thinks himself the master of others, and still remains a greater slave than they.” Regardless of the political independence each individual’s behavior is highly regulated by law and regulation. Our freedoms are actually very limited. They are bounded not only by law but also the practicalities of earning a living, maintaining a residence, having a family, and limitations on resources. Our freedom is also highly constrained by the laws of physics, chemistry, and biology. After all, we can’t fly, become taller, change our eye color, stay underwater for protracted periods, stay awake continuously, or withstand cold or heat outside of a fairly small range, and we’re not faster than a speeding bullet. How much freedom do we actually have in any particular day?

 

Independence Day, though, does celebrate acquiring many soft freedoms. The freedoms to think and express our opinions and ideas, to worship as we please, to vote for whoever we like, to associate with whomever we choose, to live wherever we like, etc. Although there are bounds to many of these freedoms by the requirements of public safety, economics, cultural norms, and the practicalities of existence, these are very important and significant freedoms. Perhaps that is what we’re really celebrating, these soft freedoms that were provided by our Constitution as a result of the War for Independence.

 

Regardless, Independence Day should be celebrated mindfully. It is often spent with family and friends and the pleasure of these interactions can be amplified by doing it mindfully; by being truly present for them and deeply listening to them rather than thinking about our next response. By being mindful we can see them with compassion and understanding. Being in, and focusing on, the present moment we can enjoy these interactions, we can enjoy the picnics and parades, we can enjoy the fireworks, rather than thinking about where we would rather be or where we’re going next. We can find happiness precisely where we are.

 

But are we truly free. A bit of mindful reflection reveals that we find existence very unsatisfactory. In fact, unsatisfactoriness is everywhere. We’re not satisfied with things as they are and want them to be different. We’re not satisfied with where we live and want to have a nicer home.  We’re not satisfied with our appearance and want to lose weight. We’re not satisfied with what people think of us and want to be universally liked. We’re not satisfied with how we’re treated by our spouses and want them to be more understanding. We’re not satisfied with our children and want them to be obedient, respectful, straight “A” students and star athletes. We’re not satisfied with our health and want to have fewer aches and pains. We’re not satisfied with our jobs and want to make more money, have more time off and be appreciated by our bosses and coworkers. Even on the very short-term, things are not satisfactory. We want the car ahead of us to be moving faster, we want time to pass quickly so that we can be done with work for the day, we want to stop ruminating about past indiscretions, we want to finish a meal quickly so we can get back to the TV, etc. In other words, we’re not free from our desires. In fact, we’re slaves to them. We’re not happy with the way things are. In fact, we seem to want everything to be different. So, we can’t be truly free as long as we’re slaves to our desires.

 

True freedom can only be produced when we are liberated from our incessant needs and wants. That is not to say that we shouldn’t have desires, but rather that we will not be controlled by them. True freedom comes from equanimity. It comes when we’re able to desire something, seek it out, but be OK whether we get it or not. It comes when we not only accept the way things are but enjoy each second for what it is, a precious moment in a limited lifetime. It comes when what other people do and say is seen as a reflection of them and not of us and comes when we look at them with compassion and understanding. In other words, we can want ourselves, things, people, and circumstances to be different but we accept them as they are and appreciate and enjoy life and each experience as a gift.

 

This sounds wonderful, but is it achievable? It sure doesn’t seem so as ourselves and the people we know haven’t achieved it. Is it possible to actually get to this state of complete freedom? It is, but it takes effort and discipline. There have been many instances throughout history and there are many exemplars present right now of people who have achieved complete equanimity. Jesus is a wonderful example. He worked hard and suffered to make his world a better place but in the end accepted what was. The Buddha, Christian mystics, Sufi masters, Zen masters, Gandhi, and a host of everyday people have all achieved true liberation. So, it is possible.

 

We do not, however, have to be aiming only at complete liberation. It is far better to work to simply improve on our current state and thereby become more and more liberated. We can do this by engaging in mindfulness practices such as meditation, yoga, tai chi, contemplative prayer, etc. we can learn to focus more and more on the present moment. We can learn to appreciate what is. We can learn to enjoy every moment. Just by improving a little we can become happier and happier, more accepting, and more liberated from our desires. We can achieve greater equanimity and with it greater freedom. But, we get there slowly and incrementally, building toward our complete liberation. Now wouldn’t that be a reason to celebrate Independence Day.

“Happy 4th of July.  Celebrate your freedom mindfully- express love and gratitude for all situations, people, places and things you encounter today. This practice of loving what is, is a mindful behavior. When we celebrate our freedom as a country, we bring love to the abundance we are free to encounter today. Take each situation you encounter as an opportunity to express your love, gratitude  – any kindness will do – that is freedom!” –  Regina Huelsenbeck

Meditation Alter Short-Term and Long-Term Breathing

Meditation Alter Short-Term and Long-Term Breathing

 

By John M. de Castro, Ph.D.

 

“By activating the parasympathetic nervous system, meditation healthfully slows down heart rate, breathing rate, blood pressure, sweating, and soothing all other sympathetic nervous system fight or flight functions.” – EOC Institute

 

In our lives we are confronted with a variety of situations and environments. In order to successfully navigate these differing situations, we must be able to adapt and self-regulate. The Autonomic Nervous System (ANS) is designed to adapt physiologically to the varying demands on us. It is composed of 2 divisions; the sympathetic division underlies activation, including increases in respiration, heart rate, and blood pressure, while the parasympathetic division underlies relaxation, including decreases in respiration, heart rate, and blood pressure.

 

Mindfulness training has been shown through extensive research to be effective in improving physical and psychological health and particularly with the physical and psychological reactions to stress. These include alterations of the Autonomic Nervous System (ANS) producing physiological relaxation including reductions in breathing rates. But the effects of meditation on breathing has not been well studied.

 

In today’s Research News article “Breath Rate Variability: A Novel Measure to Study the Meditation Effects.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6329220/), Soni and colleagues recruited experienced meditators and nonmeditators who expressed interest in meditation. They were asked to close their eyes and sit quietly for 15 minutes. During which time they measured for heart rate and respiration.

 

They found that the meditators had significantly greater mean and median breathing time, standard deviation of the breath to breathe interval, standard deviation of the average breath to breathe interval, root mean square standard deviation of the average breath to breathe interval and significantly lower breath rate. These measures suggest that meditation practice produces short-term changes in breathing when at rest. In addition, heart rate and breath rate variability measures suggested that there was a significant increase in long-term parasympathetic input in the meditators.

 

These are complex but interesting results that suggest that meditation practice alters respiration over both the short and long term. On the short term, while at rest with eyes closed meditators have better, more relaxed, control of respiration. On the long term, meditator appear to have increased parasympathetic control of respiration. This suggest an overall relaxation of respiration. Meditation would appear to alter the overall balance in the autonomic nervous system toward increased parasympathetic (relaxation) control and decreases sympathetic (activation) control. This may explain some of the benefits of meditation for stress reduction.

 

So, relax short-term and long-term breathing with meditation

 

“all forms of meditation studied reduce physiological stress markers in one way or another, and therefore, all forms are likely beneficial in managing stress.” – Michaela Pascoe

Study Summary

 

Soni, R., & Muniyandi, M. (2019). Breath Rate Variability: A Novel Measure to Study the Meditation Effects. International journal of yoga, 12(1), 45–54. doi:10.4103/ijoy.IJOY_27_17

 

Abstract

Context:

Reliable quantitative measure of meditation is still elusive. Although electroencephalogram (EEG) and heart rate variability (HRV) are known as quantitative measures of meditation, effects of meditation on EEG and HRV may well take long time as these measures are involuntarily controlled. Effect of mediation on respiration is well known; however, quantitative measures of respiration during meditation have not been studied.

Aims:

Breath rate variability (BRV) as an alternate measure of meditation even over a short duration is proposed. The main objective of this study is to test the hypothesis that BRV is a simple measure that differentiates between meditators and nonmeditators.

Settings and Design:

This was a nonrandomized, controlled trial. Volunteers meditate in their natural habitat during signal acquisition.

Subjects and Methods:

We used Photo-Plythysmo-Gram (PPG) signal acquisition system from BIO-PAC and recorded video of chest and abdomen movement due to respiration during a short meditation (15 min) session for 12 individuals (all males) meditating in a relaxed sitting posture. Seven of the 12 individuals had substantial experience in meditation, while others are controls without any experience in meditation. Respiratory signal from PPG signal was derived and matched with that of the video respiratory signal. This derived respiratory signal is used for calculating BRV parameters in time, frequency, nonlinear, and time-frequency domain.

Statistical Analysis Used:

First, breath-to-breath interval (BBI) was calculated from the respiration signal, then time domain parameters such as standard deviation of BBI (SDBB), root mean square value of SDBB (RMSSD), and standard deviation of SDBB (SDSD) were calculated. We performed spectral analysis to calculate frequency domain parameters (power spectral density [PSD], power of each band, peak frequency of each band, and normalized frequency) using Burg, Welch, and Lomb–Scargle (LS) method. We calculated nonlinear parameters (sample entropy, approximate entropy, Poincare plot, and Renyi entropy). We calculated time frequency parameters (global PSD, low frequency-high frequency [LF-HF] ratio, and LF-HF power) by Burg LS and wavelet method.

Results:

The results show that the mediated individuals have high value of SDSD (+24%), SDBB (+29%), and RMSSD (+26%). Frequency domain analysis shows substantial increment in LFHF power (+73%) and LFHF ratio (+33%). Nonlinear parameters such as SD1 and SD2 were also more (>20%) for meditated persons.

Conclusions:

As compared to HRV, BRV can provide short-term effect on anatomic nervous system meditation, while HRV shows long-term effects. Improved autonomic function is one of the long-term effects of meditation in which an increase in parasympathetic activity and decrease in sympathetic dominance are observed. In future works, BRV could also be used for measuring stress.

Eye Movements Reveal Mind Wandering During Meditation

Eye Movements Reveal Mind Wandering During Meditation

 

By John M. de Castro, Ph.D.

 

“Distractions in the mind translate to micro movements in the eyes or eyelids, and vice-versa. Stillness of eyes brings stillness of mind, and vice-versa.” – Giovanni

 

We spend a tremendous amount of waking time with our minds wandering and not on the present environment or the task at hand. We daydream, plan for the future, review the past, ruminate on our failures, exalt in our successes. In fact, we spend almost half of our waking hours off task with our mind wandering. Mind wandering is also present even during meditation. Mind wandering interferes with our concentration on the present moment. Focused meditation, on the other hand, is the antithesis of mind wandering. Indeed, the more mindful we are the less the mind wanders.

 

A system of the brain known as the Default Mode Network (DMN) becomes active during wind wandering and relatively quiet during focused on task behavior. Meditation is known to reduce the size, connectivity, and activity of the Default Mode Network (DMN).  Hence, brain activity may help identify mind wandering when it occurs. Eye movements occur even when the eyes are closed and during meditation. They may also be indicators of mind wander in during meditation.

 

In today’s Research News article “Spontaneous eye movements during focused-attention mindfulness meditation.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6345481/), Matiz and colleagues recruited adult experienced meditators. They engaged in a 7-minute focused breath meditation or a 7-minute mind wandering where they were asked to “remember or imagine one or more events of their past or future in which they, or another person, were the protagonist.” During the session brain activity, the electroencephalogram (EEG), was recorded. They derived a measure from the EEG that indicated vertical and horizontal eye movements. They also measured the total amount of meditation experience for each participant.

 

They found that during the 7-minutes of mind wandering there were significantly more eye movements, including both vertical and horizontal movements, than during the7-minutes of  focused meditation. In addition, they found that the more meditation experience that the meditator had, the fewer the eye movements that were recorded under both conditions. Hence, experienced meditators not only move their eyes less during meditation and but also during mind wandering.

 

These are interesting findings that suggest that analysis of the brain’s electrical activity, electroencephalogram (EEG), may be able to detect when mind wandering is occurring during meditation. This could lead to the possibility of providing biofeedback to the meditator when the mind is wandering, lessening the amount of mind wandering and thereby deepening the meditative experience. This is an intriguing possibility for future research.

Abstract

Oculometric measures have been proven to be useful markers of mind-wandering during visual tasks such as reading. However, little is known about ocular activity during mindfulness meditation, a mental practice naturally involving mind-wandering episodes. In order to explore this issue, we extracted closed-eyes ocular movement measurements via a covert technique (EEG recordings) from expert meditators during two repetitions of a 7-minute mindfulness meditation session, focusing on the breath, and two repetitions of a 7-minute instructed mind-wandering task. Power spectral density was estimated on both the vertical and horizontal components of eye movements. The results show a significantly smaller average amplitude of eye movements in the delta band (1–4 Hz) during mindfulness meditation than instructed mind-wandering. Moreover, participants’ meditation expertise correlated significantly with this average amplitude during both tasks, with more experienced meditators generally moving their eyes less than less experienced meditators. These findings suggest the potential use of this measure to detect mind-wandering episodes during mindfulness meditation and to assess meditation performance.
