Improve Psychological Functioning with Mindfulness

 

By John M. de Castro, Ph.D.

 

” the positive potential benefits of mindfulness practice are more attentional control, more effective emotional regulation, enhanced social relationships, reduced risk for physical ailments, enhanced immune system functioning, and better sleep quality.” – Jason Linder

 

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. The breadth and depth of benefits is unprecedented. There is no other treatment or practice that has been shown to come anyway near the range of mindfulness’ positive benefits.

 

The clustering of these benefits may supply a clue as to how mindfulness training is working to improve mental health. This can be investigated by looking at the interrelationships between the effects of mindfulness training. In today’s Research News article “Does mindfulness change the mind? A novel psychonectome perspective based on Network Analysis.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6638953/), Roca and colleagues apply network analysis to investigate the interrelationships between a large number of effects of Mindfulness-Based Stress Reduction (MBSR) training.

 

They recruited healthy adult participants in a Mindfulness-Based Stress Reduction (MBSR) program. The MBSR program consisted of 32 hours of training separated into 8 weekly group sessions involving meditation, yoga, body scan, and discussion. The patients were also encouraged to perform daily practice. They were measured before and after MBSR training for meditation experience, and psychological and physical health problems, and 5 categories of mindfulness effects; 1) Mindfulness, including five facets, decentering, non-attachment, and bodily awareness, 2) Compassion, including compassion towards oneself and others and empathy, 3) Psychological well-being, including satisfaction with life, optimism, and overall well-being, 4) Psychological distress, including anxiety, stress, and depression, and 5) Emotional and cognitive control, including emotional regulation, rumination, thought suppression and attentional control.

 

They found that after MBSR training there were significant improvements in effectively all of the five categories. This is not new as much research has demonstrated that mindfulness training produces improvements in mindfulness, compassion, psychological well-being, psychological distress, and emotional and cognitive control.

 

These data were then subjected to network analysis. Prior to MBSR training the network analysis revealed clustering in three paths “mindfulness and self-compassion; clinical symptoms and rumination; and most of FFMQ mindfulness components with attentional control measure.” After MBSR training, however, there was a network reorganization such that the three paths disappeared and were replaced by two paths, psychopathological and adaptive.

 

Centrality measures in the network analysis indicated that both prior to and after MBSR training the most central, fundamental, and interrelated components were all facets of mindfulness and all well-being measures. In addition, Community Analysis revealed that mindfulness, compassion, and emotional regulation were the most highly associated components.

 

The results are complex but suggest that Mindfulness-Based Stress Reduction (MBSR) training reorganizes the associations of psychological variables, simplifying them into two categories representing distress and adaptation. The training may help the individual see the interrelationships of the problems they have and the solutions employed. The results further suggest, not surprisingly, that mindfulness, compassion, and emotion regulation are central to the benefits of mindfulness training. Many other benefits flow from these.

 

So, improve psychological functioning with mindfulness.

Abstract

If the brain is a complex network of functionally specialized areas, it might be expected that mental representations could also behave in a similar way. We propose the concept of ‘psychonectome’ to formalize the idea of psychological constructs forming a dynamic network of mutually dependent elements. As a proof-of-concept of the psychonectome, networks analysis (NA) was used to explore structural changes in the network of constructs resulting from a psychological intervention. NA was applied to explore the effects of an 8-week Mindfulness-Based Stress Reduction (MBSR) program in healthy participants (N = 182). Psychological functioning was measured by questionnaires assessing five key domains related to MBSR: mindfulness, compassion, psychological well-being, psychological distress and emotional-cognitive control. A total of 25 variables, covering the five constructs, were considered as nodes in the NA. Participants significantly improved in most of the psychological questionnaires. More interesting from a network perspective, there were also significant changes in the topological relationships among the elements. Expected influence and strength centrality indexes revealed that mindfulness and well-being measures were the most central nodes in the networks. The nodes with highest topological change after the MBSR were attentional control, compassion measures, depression and thought suppression. Also, cognitive appraisal, an adaptive emotion regulation strategy, was associated to rumination before the MBSR program but became related to mindfulness and well-being measures after the program. Community analysis revealed a strong topological association between mindfulness, compassion, and emotional regulation, which supports the key role of compassion in mindfulness training. These results highlight the importance of exploring psychological changes from a network perspective and support the conceptual advantage of considering the interconnectedness of psychological constructs in terms of a ‘psychonectome’ as it may reveal ways of functioning that cannot be analyzed through conventional analytic methods.

Improve Thinking in Adolescents with Yoga Practice

Improve Thinking in Adolescents with Yoga Practice

 

By John M. de Castro, Ph.D.

 

“Yoga is like music. The rhythm of the body, the melody of the mind, and the harmony of the soul creates the symphony of life.” B.K.S. Iyengar

 

Yoga practice has been shown to have a large number of beneficial effects on the psychological, emotional, and physical health of the individual and is helpful in the treatment of mental and physical illness. The acceptance of yoga practice has spread from the home and yoga studios to its application with children in schools. Studies of these school programs have found that yoga practice produces a wide variety of positive emotional, psychosocial, and physical benefits.

Teachers also note improvements in their students following yoga practice. These include improved classroom behavior, social–emotional, and cognitive skills. In addition, school records, academic tests, and physiological measures have shown that yoga practice produces improvements in student grades and academic performance.

 

To better understand the effects of yoga practice on adolescents it is important to take into consideration that yoga is a not only a mindfulness practice, but it is also a physical exercise. It is important to compare yoga practice in schools to other forms of physical exercise to determine if yoga produces its benefits because of improved mindfulness or because of the physical exercise provided.

 

In today’s Research News article “.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6521753/), Vhavle and colleagues recruited adolescents and randomly assigned them to participate in school in 1-hour daily practice for 2 months of either yoga or physical exercise. They were measured before and after training for executive function, cognition, attention, visual scanning, and memory with a numerical and an alphabetical trail making test.

 

All participants had fast times in completing the trail making tests indicating high levels of ability. The researchers found that both groups took significantly longer after training than before for the numerical trail making test. Only the yoga group took a significantly shorter time to complete the alphabetical trail making test after training than before and this was significantly different from the exercise group.

 

The numerical trail making test emphasizes visual scanning and cognitive function. The scores were very fast and so all of the students were very adept at this test. Hence, there may have been a ceiling effects making it impossible to detect further improvements. On the other hand, the alphabetical trail making test measures executive function, attention, and working memory and yoga practice produced significant improvement s in performance. These results then, suggests that school-based yoga practice may enhance adolescents’ thinking skills better than physical exercise. This suggests that the mindfulness component and not the exercise component of yoga practice is the most important aspect of the practice for the improvement of thinking ability in the youths.

 

So, improve thinking in adolescents with yoga practice.

 

“Studies also show that exercise facilitates children’s executive function (i.e., processes required to select, organize, and properly initiate goal-directed actions) by increasing activation in the prefrontal cortex and serotonergic system. By integrating physical movement with breathing exercises and mindful awareness, yoga serves as a promising form of physical and cognitive training to enhance learning-related outcomes.” – Yoga4Classrooms

Study Summary

 

Vhavle, S. P., Rao, R. M., & Manjunath, N. K. (2019). Comparison of Yoga versus Physical Exercise on Executive Function, Attention, and Working Memory in Adolescent Schoolchildren: A Randomized Controlled Trial. International journal of yoga, 12(2), 172–173. doi:10.4103/ijoy.IJOY_61_18

 

Abstract

Purpose:

Executive function, attention, and memory are an important indicator of cognitive health in children. In this study, we analyze the effect of yoga and physical exercise on executive functioning, attention, and memory.

Methods:

In this prospective two-armed randomized controlled trial, around 802 students from ten schools across four districts were randomized to receive daily 1 h yoga training (n = 411) or physical exercise (n = 391) for 2 months. Executive function, attention, and memory were studied using Trail Making Test (TMT). Yoga (n = 377) and physical exercise (n = 371) students contributed data to the analyses. The data were analyzed using intention-to-treat approach using Student’s t-test.

Results:

There was a significant increase in numerical TMT (TMTN) values within yoga (t = −2.17; P < 0.03) and physical activity (PA) (t = −3.37; P < 0.001) groups following interventional period. However, there was no significant change in TMTN between yoga and PA groups (t = 0.44; P = 0.66). There was a significant increase in alphabetical TMT (TMTA) values within yoga (t = 6.21; P < 0.00) and PA groups (t = 1.19; P < 0.234) following interventional period. However, there was no significant change in TMTA between yoga and PA groups (t = 3.46; P = 0.001).

Conclusion:

The results suggest that yoga improves executive function, attention, and working memory as effectively as physical exercise intervention in adolescent schoolchildren.

Reduce Psychological Distress Produced by Critical Thinking with Mindfulness

Reduce Psychological Distress Produced by Critical Thinking with Mindfulness

 

By John M. de Castro, Ph.D.

 

“The most active form of developing critical thinking is through meditation. Meditation makes you exercise control of mind over matter. Your mind becomes an active place for several activities such as: cleansing of mind from rubbish which may lead to wrong actions and decisions; accepting healthy thoughts into the cleansed mind; and letting the good ideas come to work and change the way you think.” – Operation Meditation

 

We tend to believe that the ability to think critically is a major positive characteristic that should be trained. For intellectual tasks this is probably true. But in the emotional realm, critical thinking might actually be negative and lead to greater emotional distress. Disordered, self-critical, thinking is associated with a variety of mental illnesses. This form of thinking can produce cognitive distortions that consist of dysfunctional reasoning including arbitrary inference, false dichotomy, selective abstraction, and overgeneralization. Mindfulness has been shown to improve thought processes and also the individual’s ability to regulate their emotions. So, mindfulness may counteract the negative emotional consequences of critical thinking.

 

In today’s Research News article “The Moderating Effect of Mindfulness on the Mediated Relation Between Critical Thinking and Psychological Distress via Cognitive Distortions Among Adolescents.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6606771/), Su and Shum recruited high school seniors and had them complete measures of anxiety, depression, cognitive distortions, mindfulness, and critical thinking. They then subjected these measures to regression analysis.

 

They found that the higher the levels of cognitive distortions the higher the levels of stress, anxiety, and depression, and lower levels of mindfulness. In other words, psychological distress (anxiety, depression, and stress) were associated with faulty thinking. They then performed linear structural modelling and found that critical thinking was associated with psychological distress directly and indirectly by being associated with cognitive distortions which is, in turn, is associated with psychological distress. They found that mindfulness moderates the relationship between critical thinking and psychological distress. It does so by being related to lower cognitive distortions and by being related to lower psychological distress.

 

These results are interesting and suggest that having high critical thinking can lead to distorted thinking that can, in turn, lead to greater anxiety, depression, and stress. This faulty thinking may be related to thinking about the self, being overly critical of the self and thereby producing psychological problems. The results also suggest that mindfulness can to some extent blunt this process by making it less likely that distorted thinking will develop and also by directly reducing anxiety, depression, and stress. Hence, mindfulness may allow for critical thinking without producing psychological distress.

 

So, reduce psychological distress produced by critical thinking with mindfulness.

Abstract

Critical thinking has been widely regarded as an indispensable cognitive skill in the 21st century. However, its associations with the affective aspects of psychological functioning are not well understood. This study explored the interrelations between trait mindfulness, critical thinking, cognitive distortions, and psychological distress using a moderated mediation model. The sample comprised 287 senior secondary school students (57% male and 43% female) aged 14–19 from a local secondary school in Hong Kong. The results revealed that high critical thinking was significantly associated with high levels of psychological distress when mindful awareness was low among adolescents. Trait mindfulness was found to moderate the indirect effects of critical thinking on psychological distress via cognitive distortions as the mediator. Specifically, in low trait mindfulness conditions, critical thinking was found to associate positively with cognitive distortions and psychological distress. Such associations were not observed in high trait mindfulness conditions. The findings reveal that though critical thinking has positive associations with cognitive functioning, its associations with affective well-being might be negative. The results also suggest that mindfulness might play an important role in preventing the possible psychological distress associated with critical thinking. Educational implications relating to the fostering of critical thinking and mindful awareness are discussed.

Improve Attentional Monitoring of Others Emotions with Mindfulness

Improve Attentional Monitoring of Others Emotions with Mindfulness

 

By John M. de Castro, Ph.D.

 

“experience with mindfulness meditation is associated with distinct reactions to emotional provocations in attention and social decision-making tasks, and have implications for understanding the relationship between mindfulness meditation and emotion regulation.” – Deidre Reis

 

Mindfulness practice has been shown to improve emotion regulation. Practitioners demonstrate the ability to fully sense and experience emotions, but respond to them in more appropriate and adaptive ways. In other words, mindful people are better able to experience yet control their responses to emotions. The ability of mindfulness training to improve emotion regulation is thought to be the basis for a wide variety of benefits that mindfulness provides to mental health and the treatment of mental illness especially depression and anxiety disorders.

 

There is evidence that mindfulness training improves emotion regulation by altering the brain. A common method to study the activity of the nervous system is to measure the electrical signal at the scalp above brain regions. Changes in this activity are measurable with mindfulness training. One method to observe emotional processing in the brain is to measure the changes in the electrical activity that occur in response to specific emotional stimuli. These are called event-related potentials or ERPs. The signal following a stimulus changes over time.

 

The fluctuations of the signal after specific periods of time are thought to measure different aspects of the nervous system’s processing of the stimulus. The N200 response in the evoked potential (ERP) is a negative going electrical response occurring between a 2.0 to 3.5 tenths of a second following the target stimulus presentation. The N200 component is thought to reflect attentional monitoring of conflict. The P300 response in the evoked potential (ERP) is a positive going electrical response occurring between a 3.5 to 6.0 tenths of a second following the target stimulus presentation. The P300 component is thought to reflect inhibitory processes.

 

In today’s Research News article “Brief mindfulness training enhances cognitive control in socioemotional contexts: Behavioral and neural evidence.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6641506/), Quaglia and colleagues recruited healthy adults and randomly assigned them to receive 4 20-minute sessions of either mindfulness training or book listening. They were measured before and after training for mindfulness and were tested with an emotional go no-go task in which they were asked to press a button when a picture of a face was presented that expressed a particular emotion and not respond to faces with other emotions. The pictures were of faces expression either anger, happiness, or neutral emotions. During the task the brain electrical activity was recorded with an electroencephalograph (EEG).

 

They found, as expected, that the group receiving mindfulness training, in comparison to the book listening group, had significantly higher mindfulness following training. They found that the mindfulness group, after training had significantly better scores, including both speed and accuracy, for facial emotion discrimination than the control group. With the evoked potentials, they found that on no-go trials, trials where the target facial emotion was not present. The mindfulness trained participants had significantly larger N200 amplitudes than the controls.

 

These results suggest that mindfulness training makes the individual more sensitive to emotional expressions by others. The evoked potentials in the EEGs suggest that mindfulness training did this by enhancing the brain’s ability to pay attention and monitor conflict allowing the individual to better withhold responses when appropriate. This could, in part, explain the improvement of emotion regulation with mindfulness training and may be the basis for the prior findings that mindfulness training improves responding in social contexts.

 

So, improve attentional monitoring of others emotions with mindfulness.

Abstract

In social contexts, the dynamic nature of others’ emotions places unique demands on attention and emotion regulation. Mindfulness, characterized by heightened and receptive moment-to-moment attending, may be well-suited to meet these demands. In particular, mindfulness may support more effective cognitive control in social situations via efficient deployment of top-down attention. To test this, a randomized controlled study examined effects of mindfulness training (MT) on behavioral and neural (event-related potentials [ERPs]) responses during an emotional go/no-go task that tested cognitive control in the context of emotional facial expressions that tend to elicit approach or avoidance behavior. Participants (N = 66) were randomly assigned to four brief (20 min) MT sessions or to structurally equivalent book learning control sessions. Relative to the control group, MT led to improved discrimination of facial expressions, as indexed by d-prime, as well as more efficient cognitive control, as indexed by response time and accuracy, and particularly for those evidencing poorer discrimination and cognitive control at baseline. MT also produced better conflict monitoring of behavioral goal-prepotent response tendencies, as indexed by larger No-Go N200 ERP amplitudes, and particularly so for those with smaller No-Go amplitude at baseline. Overall, findings are consistent with MT’s potential to enhance deployment of early top-down attention to better meet the unique cognitive and emotional demands of socioemotional contexts, particularly for those with greater opportunity for change. Findings also suggest that early top-down attention deployment could be a cognitive mechanism correspondent to the present-oriented attention commonly used to explain regulatory benefits of mindfulness more broadly.

Improve Children and Adolescents Mental Health with Mindfulness

 

By John M. de Castro, Ph.D.

 

“In the last few years mindfulness has emerged as a way of treating children and adolescents with conditions ranging from ADHD to anxiety, autism spectrum disorders, depression and stress. And the benefits are proving to be tremendous.” – Julianne Garey

 

Childhood is a miraculous period during which the child is dynamically absorbing information from every aspect of its environment. This occurs almost without any intervention from the adults as the child appears to be programmed to learn. It is here that behaviors, knowledge, skills, and attitudes are developed that shape the individual.

 

Adolescence is a time of mental, physical, social, and emotional growth. It is during this time that higher levels of thinking, sometimes called executive function, develops. But adolescence can be a difficult time, fraught with challenges. During this time the child transitions to young adulthood; including the development of intellectual, psychological, physical, and social abilities and characteristics. There are so many changes occurring during this time that the child can feel overwhelmed and unable to cope with all that is required.

 

Mindfulness training for children and adolescents has been shown to have very positive effects. These include academic, cognitive, psychological, and social domains. Mindfulness training has been shown to improve emotion regulation and to benefit the psychological and emotional health of adolescents. Importantly, mindfulness training with children and adolescents appears to improve the self-concept, improves attentional ability and reduces stress. The research findings and evidence are accumulating. So, it makes sense to step back and review and summarize what has been learned regarding the effectiveness of mindfulness training for the cognitive growth and mental health and well-being of children and adolescents.

 

In today’s Research News article “Research Review: The effects of mindfulness-based interventions on cognition and mental health in children and adolescents – a meta-analysis of randomized controlled trials.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6546608/), Dunning and colleagues review, summarize and perform a meta-analysis of randomized controlled trials of the effects of mindfulness training on the cognitive ability, psychological health, and well-being of children and adolescents. They identified 33 published randomized controlled trials, 17 of which had active control conditions.

 

They found that over all published studies, mindfulness training resulted in improved cognition and executive function, with larger effects for older children and adolescents. Mindfulness training also produced significantly increased mindfulness and decreased negative behaviors, stress, anxiety and depression. increased mindfulness and decreased stress, anxiety and depression were still significant. But when mindfulness practices were compared to active control conditions cognitive improvements were no longer significant but there were still significant increases in mindfulness and decreases in stress, anxiety and depression.

 

These results are interesting and suggest that mindfulness training produces significant improvements in the mental health of children and adolescents. The results, however, suggest that reported improvements in cognition and behavior may be due to placebo or experimenter bias effects as these same improvements occurred with active control conditions. The improvements in cognitive ability appears to be maximized in adolescents when high level executive functions are developing. The lack of significant effects in studies with active control conditions may have been due to the small number of studies, 7, that had active controls and studied cognition.

 

Regardless, the accumulated research suggests that training children and adolescents in mindfulness may help them navigate the difficult emotional challenges confronting them during development.

 

So, improve children and adolescents’ mental health with mindfulness.

 

“For children, mindfulness can offer relief from whatever difficulties they might be encountering in life. It also gives them the beauty of being in the present moment.” – Annaka Harris

Research Review: The effects of mindfulness-based interventions on cognition and mental health in children and adolescents – a meta-analysis of randomized controlled trials. Journal of child psychology and psychiatry, and allied disciplines, 60(3), 244–258. doi:10.1111/jcpp.12980

 

Abstract

Background

Mindfulness based interventions (MBIs) are an increasingly popular way of attempting to improve the behavioural, cognitive and mental health outcomes of children and adolescents, though there is a suggestion that enthusiasm has moved ahead of the evidence base. Most evaluations of MBIs are either uncontrolled or nonrandomized trials. This meta-analysis aims to establish the efficacy of MBIs for children and adolescents in studies that have adopted a randomized, controlled trial (RCT) design.

Methods

A systematic literature search of RCTs of MBIs was conducted up to October 2017. Thirty-three independent studies including 3,666 children and adolescents were included in random effects meta-analyses with outcome measures categorized into cognitive, behavioural and emotional factors. Separate random effects meta-analyses were completed for the seventeen studies (n = 1,762) that used an RCT design with an active control condition.

Results

Across all RCTs we found significant positive effects of MBIs, relative to controls, for the outcome categories of Mindfulness, Executive Functioning, Attention, Depression, Anxiety/Stress and Negative Behaviours, with small effect sizes (Cohen’s d), ranging from .16 to .30. However, when considering only those RCTs with active control groups, significant benefits of an MBI were restricted to the outcomes of Mindfulness (d = .42), Depression (d = .47) and Anxiety/Stress (d = .18) only.

Conclusions

This meta-analysis reinforces the efficacy of using MBIs for improving the mental health and wellbeing of youth as assessed using the gold standard RCT methodology. Future RCT evaluations should incorporate scaled-up definitive trial designs to further evaluate the robustness of MBIs in youth, with an embedded focus on mechanisms of action.

Key points

  • Mindfulness based interventions (MBIs) are a popular way of attempting to improve the mental and physical health outcomes of children and adolescents.
  • This is the first meta-analysis of MBIs with youth composed exclusively of randomized controlled trials (RCTs) including RCTs with active control groups – the gold standard in intervention studies.
  • When using the gold standard research design results showed that MBIs are useful in improving Depression and Anxiety outcomes, but not behavioural or cognitive outcomes,
  • The meta-analysis advocates the use of MBIs for improving mental health in young people.
  • Future RCT evaluations should incorporate scaled-up definitive trial designs to further evaluate the robustness of MBIs in youth, with an embedded focus on mechanisms of action.

Alter the Brain for Improved Memory with Aging with Tai Chi

Alter the Brain for Improved Memory with Aging with Tai Chi

 

By John M. de Castro, Ph.D.

 

“our brain physiology and memory can be changed with Tai Chi. . . Brain scans show neural changes in the Tai Chi group associated with better memory, especially in cognitive areas associated with spatial memory.” – Paul Lam

 

The aging process involves a systematic progressive decline in every system in the body, the brain included. This includes our mental abilities which decline with age including impairments in memory, attention, and problem-solving ability. It is inevitable and cannot be avoided.

 

Using modern neuroimaging techniques, scientists have been able to view the changes that occur in the nervous system with aging. In addition, they have been able to investigate various techniques that might slow the process of neurodegeneration that accompanies normal aging. They’ve found that mindfulness practices reduce the deterioration of the brain that occurs with aging restraining the loss of neural tissue. Indeed, the brains of practitioners of meditation and yoga have been found to degenerate less with aging than non-practitioners. Tai Chi and Qigong have also been shown to be beneficial in slowing or delaying physical and mental decline with aging and to increase brain matter in the elderly.

 

An interconnected system of the brain known as the Default Mode Network (DMN) is involved in internally focused tasks such as recalling memories, daydreaming, sleeping, imagining the future and trying to take the perspective of others. The DMN involves neural structures including the medial prefrontal cortex, anterior and posterior cingulate cortices, precuneus, inferior parietal cortex, and lateral temporal cortex. These areas of the DMN are functionally connected, such that they are simultaneously active during memory retrieval. It is possible that Tai Chi practice improves memory in aging adults by altering the functional connectivity of the DMN.

 

In today’s Research News article “Different Modulation Effects of Tai Chi Chuan and Baduanjin on Resting State Functional Connectivity of the Default Mode Baduanjin is a mind-body training that is very similar to Tai Chi and consists of 8 movements for limbs, body-trunk, and eye movements. Network in Older Adults.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6374601/), Liu and colleagues recruited healthy older participants, aged 50 to 70 years, who had not been regularly exercising and randomly assigned them to a health education program or to engage in a Tai Chi or Baduanjin practice for 60 minutes per session, five days per week, for 12 weeks. Baduanjin is a mind-body training that is very similar to Tai Chi and consists of 8 movements for limbs, body-trunk, and eye movements. Before and after the 12-week intervention period the participants were measured for memory function and underwent Magnetic Resonance Imaging (MRI) scans.

 

They found that in comparison to baseline and the health education control group the older adults who practiced Tai Chi or Baduanjin had significant improvements in memory function. The MRI scans demonstrated increased Tai Chi Practice produced functional connectivity within the Default Mode Network (DMN) between the medial prefrontal cortex and right putamen/caudate and the cingulate cortex and right putamen/caudate. On the other hand, Baduanjin practice produced decreased functional connectivity between the medial prefrontal cortex and orbital prefrontal gyrus/putamen.

 

These results are interesting and suggest that both Tai Chi and Baduanjin practice improve memory in older adults and also alter the connectivity between structures in the Default Mode Network (DMN). Interestingly, the two practices appear to produce different changes in functional connectivity within the DMN. This suggests that the two practice my improve memory in different ways, both altering the DMN, but differently.

 

The results demonstrate as has previous research that ancient Chinese mindful movement practices help to restrain age related deterioration in the memory processes. These mindful movement practices are gentle and safe, are appropriate for all ages including the elderly and for individuals with illnesses that limit their activities or range of motion, are inexpensive to administer, can be performed in groups or alone, at home or in a facility, and can be quickly learned. In addition, they can be practiced in social groups. This can make it fun, improving the likelihood of long-term engagement in the practice. So, Tai Chi and Baduanjin practices would appear to be an excellent gentle practice to improve memory in aging individuals.

 

So, alter the brain for improved memory with aging with Tai Chi and Baduanjin practices.

Different Modulation Effects of Tai Chi Chuan and Baduanjin on Resting State Functional Connectivity of the Default Mode Network in Older Adults. Social cognitive and affective neuroscience, 14(2), 217–224. Advance online publication. doi:10.1093/scan/nsz001

 

Abstract

The default mode network (DMN) plays an important role in age-related cognitive decline. This study aims to explore the modulation effect of two mind–body interventions (Tai Chi Chuan and Baduanjin) on DMN in elderly individuals. Participants between 50 and 70 years old were recruited and randomized into a Tai Chi Chuan, Baduanjin or control group. The Wechsler Memory Scale-Chinese Revision and resting-state fMRI scans were administered at baseline and following 12 weeks of exercise. Seed-based resting-state functional connectivity (rsFC) was calculated. We found that (i) compared to the Baduanjin group, Tai Chi Chuan was significantly associated with increased rsFC between the medial prefrontal cortex (mPFC) and right putamen/caudate and (ii) compared to the control group, Tai Chi Chuan increased posterior cingulate cortex rsFC with the right putamen/caudate, while Baduanjin decreased rsFC between the mPFC and orbital prefrontal gyrus/putamen. Baseline mPFC rsFC with orbital prefrontal gyrus was negatively correlated with visual reproduction subscore. These results suggest that both Tai Chi Chuan and Baduanjin can modulate the DMN, but through different pathways. Elucidating the mechanisms underlying different mind–body interventions may shed light on the development of new methods to prevent age-related diseases as well as other disorders associated with disrupted DMN.

Change Brain Connectivity for Better Attention and Thinking with Mindfulness

 

By John M. de Castro, Ph.D.

 

“mindfulness meditation training increases resting state connectivity between top-down executive control regions, highlighting an important mechanism through which it reduces stress levels.” – Daniel Reed

 

There has accumulated a large amount of research demonstrating that mindfulness has significant benefits for psychological, physical, and spiritual wellbeing. It even improves high level thinking known as executive function and emotion regulation and compassion. Its positive effects are so widespread that it is difficult to find any other treatment of any kind with such broad beneficial effects on everything from thinking to mood and happiness to severe mental and physical illnesses. This raises the question of how mindfulness training could produce such widespread and varied benefits. One possibility is that mindfulness practice results in beneficial changes in the nervous system.

 

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. The changes are complex and require sophisticated brain scanning techniques to detect. Hence there is a need to continue investigating the nature of these changes in the brain produced by meditation.

 

In today’s Research News article “Trait Mindfulness and Functional Connectivity in Cognitive and Attentional Resting State Networks.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6473082/), Parkinson and colleagues recruited undergraduate students who had never meditated, measured them for mindfulness, and scanned their brains under resting conditions with functional Magnetic Resonance Imaging (fMRI). They examined the functional connectivity of a number of established neural networks and their relationship with mindfulness.

 

They found that mindfulness was negatively related to the functional connectivity of the Default Mode Network (DMN) and positively related to the functional connectivity of the Salience Network, the Central Executive Network, and Attention Network. The Default Mode Network (DMN) has been shown to be associated with mind wandering and self-referential thinking. It is not surprising that mindfulness would be associated with lower levels of the functioning of this network. Indeed, previous work has demonstrated that mindfulness is associated with reduced “mind wandering.”

 

The Salience Network is involved in detecting and filtering important stimuli in the environment from the environment and thereby gets involved in a myriad of high level psychological and social functions. The results suggest that being more mindful is associated with being more sensitive to important information.

 

The Central Executive Network has been shown to be associated with high level thinking and behavioral control. Hence, the results further suggest that high mindfulness is associated with improved cognition. Indeed, mindfulness has been shown through extensive research to be associated with better cognitive ability.

 

Finally, the Attention Network has been found to be associated with, no surprise, the ability to attend and focus. This suggests that high mindfulness is associated with improved attention ability. Again, this reflects other research which demonstrated that mindfulness is associated with a greater ability to attend.

 

Hence the study demonstrated the associations with mindfulness with functional connectivity in various neural networks tracks the demonstrated effects of mindfulness on the individual’s ability to focus, think, and stay in the present moment. This further suggests that changes in the operations of the brain are produced by mindfulness and that hese changes in turn produced improved functional capacities.

 

So, change brain connectivity for better attention and thinking with mindfulness.

 

“Just 11 hours of learning a meditation technique induce positive structural changes in brain connectivity by boosting efficiency in a part of the brain that helps a person regulate behavior in accordance with their goals,” – University of Oregon

Parkinson, T. D., Kornelsen, J., & Smith, S. D. (2019). Trait Mindfulness and Functional Connectivity in Cognitive and Attentional Resting State Networks. Frontiers in Human Neuroscience, 13, 112. doi:10.3389/fnhum.2019.00112

 

Abstract

Mindfulness has been described as an orienting of attention to the present moment, with openness and compassion. Individuals displaying high trait mindfulness exhibit this tendency as a more permanent personality attribute. Given the numerous physical and mental health benefits associated with mindfulness, there is a great interest in understanding the neural substrates of this trait. The purpose of the current research was to examine how individual differences in trait mindfulness associated with functional connectivity in five resting-state networks related to cognition and attention: the default mode network (DMN), the salience network (SN), the central executive network (CEN), and the dorsal and ventral attention networks (DAN and VAN). Twenty-eight undergraduate participants completed the Five-Facet Mindfulness Questionnaire (FFMQ), a self-report measure of trait mindfulness which also provides scores on five of its sub-categories (Observing, Describing, Acting with Awareness, Non-judging of Inner Experience, and Non-reactivity to Inner Experience). Participants then underwent a structural MRI scan and a 7-min resting state functional MRI scan. Resting-state data were analyzed using independent-component analyses. An analysis of covariance (ANCOVA) was performed to determine the relationship between each resting state network and each FFMQ score. These analyses indicated that: (1) trait mindfulness and its facets showed increased functional connectivity with neural regions related to attentional control, interoception, and executive function; and (2) trait mindfulness and its facets showed decreased functional connectivity with neural regions related to self-referential processing and mind wandering. These patterns of functional connectivity are consistent with some of the benefits of mindfulness—enhanced attention, self-regulation, and focus on present experience. This study provides support for the notion that non-judgmental attention to the present moment facilitates the integration of regions in neural networks that are related to cognition, attention, and sensation.

Improve Attention and Hyperactivity in Kindergarten Children with Yoga

Improve Attention and Hyperactivity in Kindergarten Children with Yoga

 

By John M. de Castro, Ph.D.

 

“Yoga is a systematic workout regimen that has rejuvenating and calming effects on our body and mind. Young kids go through conflicting emotions, and yoga helps calm them down. They are also extremely flexible and therefore, a practice like yoga will help them contort their bodies in different ways.” – Shirin Mehdi

 

Yoga practice has been shown to have a large number of beneficial effects on the psychological, emotional, and physical health of the individual and is helpful in the treatment of mental and physical illness. The acceptance of yoga practice has spread from the home and yoga studios to its application with children in schools. Studies of these school programs have found that yoga practice produces a wide variety of positive psychosocial and physical benefits.

 

Teachers also note improvements in their students following yoga practice. These include improved classroom behavior and social–emotional skills, concentration, mood, ability to function under pressure, social skills, and attention and lower levels of hyperactivity. In addition, school records, academic tests have shown that yoga practice produces improvements in student grades and academic performance. This, in turn, improves the classroom experience for the teachers. Hence there are very good reasons to further study the effects of yoga practice early in children’s schooling; kindergarten.

 

In today’s Research News article “12 Weeks of Kindergarten-Based Yoga Practice Increases Visual Attention, Visual-Motor Precision and Decreases Behavior of Inattention and Hyperactivity in 5-Year-Old Children.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00796/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_963174_69_Psycho_20190416_arts_A), Jarraya and colleagues recruited kindergarten students and randomly assigned them to either practice yoga, normal physical education, or no treatment control. Yoga and Physical Education occurred twice per week for 30 minutes for 12 weeks. The Hatha yoga practice included postures and breathing exercises. The children were measured by their kindergarten teacher before and after the treatments for visual attention, visuomotor precision, inattention, and hyperactivity/impulsivity.

 

They found that in comparison to PE and control children, the children who practiced yoga had significantly improved visual attention and visuomotor precision, and significantly lower inattention, and hyperactivity/impulsivity. Visuomotor precision is a measure of cognitive function and includes measures of language, memory and learning, sensorimotor, social perception, and visuospatial processing. Hence, yoga practice improved attention, behavioral control, and higher-level thinking in the kindergarten children.

 

These are exciting results that are similar to those observed with older children. The abilities observed to have improved in the kindergarten children who practiced yoga are abilities that are essential for school performance. Attention is a key ability and that along with an additional reduction in hyperactivity sets the stage for learning. Then improved cognitive ability further heightens learning ability. This suggests that yoga practice has large benefits and should be recommended for young children to promote their ability to learn and perform in school.

 

So, improve attention and hyperactivity in kindergarten children with yoga.

 

“It sounds kind of goofy to people who don’t work with little kids, but kids that have a weak core have a hard time sitting still, and that can look like they’re not paying attention. Those are the kinds of mind-body connections you don’t think about until you start looking into it.” – Chas Zelinsky

Study Summary

 

Jarraya S, Wagner M, Jarraya M and Engel FA (2019) 12 Weeks of Kindergarten-Based Yoga Practice Increases Visual Attention, Visual-Motor Precision and Decreases Behavior of Inattention and Hyperactivity in 5-Year-Old Children. Front. Psychol. 10:796. doi: 10.3389/fpsyg.2019.00796

 

The present study assesses the impact of Kindergarten-based yoga on cognitive performance, visual-motor coordination, and behavior of inattention and hyperactivity in 5-year-old children. In this randomized controlled trial, 45 children (28 female; 17 male; 5.2 ± 0.4 years) participated. Over 12 weeks, 15 children performed Hatha-yoga twice a week for 30 min, another 15 children performed generic physical education (PE) twice a week for 30 min, and 15 children performed no kind of physical activities, serving as control group (CG). Prior to (T0) and after 12 weeks (T1), all participants completed Visual Attention and Visuomotor Precision subtests of Neuropsychological Evaluation Battery and teachers evaluated children’s behavior of inattention and hyperactivity with the Attention-Deficit/Hyperactivity Disorder (ADHD) Rating Scale-IV. At T0, no significant differences between groups appeared. Repeated measures analysis of variance revealed that following Bonferroni–Holm corrections yoga, in comparison to PE and CG, had a significant positive impact on the development on behavior of inattention and hyperactivity. Further, yoga has a significant positive impact on completion times in two visumotor precision tasks in comparison to PE. Finally, results indicate a significant positive effect of yoga on visual attention scores in comparison to CG. 12 weeks of Kindergarten-based yoga improves selected visual attention and visual-motor precision parameters and decreases behavior of inattention and hyperactivity in 5-year-old children. Consequently, yoga represents a sufficient and cost-benefit effective exercise which could enhance cognitive and behavioral factors relevant for learning and academic achievement among young children.

Become More Sensitive to Others with Meditation

 

By John M. de Castro, Ph.D.

 

“as we pay attention to our breath, our body, our lives, in this simple and gentle way, a natural consequence is the opening of the heart.” – Matthew Brensilver

 

Humans are social animals. This is a great asset for the species as the effort of the individual is amplified by cooperation. In primitive times, this cooperation was essential for survival. But in modern times it is also essential, not for survival but rather for making a living and for the happiness of the individual. This ability to cooperate is so essential to human flourishing that it is built deep into our DNA and is reflected in the structure of the human nervous system. This deep need for positive social interactions heightens the pain of social rejection.

 

Mindfulness has been found to increase prosocial behaviors such as altruism, compassion and empathy and reduce antisocial behaviors such as violence and aggression. In today’s Research News article “Exploring the Role of Meditation and Dispositional Mindfulness on Social Cognition Domains: A Controlled Study.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.00809/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_963174_69_Psycho_20190416_arts_A), Campos and colleagues examine the relationship of mindfulness to social cognition, “the mental operations that underlie social interactions, including perceiving, interpreting, and generating responses to the intentions, dispositions, and behaviors of others”.

 

They recruited a group of healthy adult meditation practitioners and a group of non-meditators and had them complete measures of mindfulness, empathy, emotion recognition, theory of mind, attribution style, depression, anxiety, and cognitive impairment. Comparing the two groups they found that the meditators had significantly higher levels of mindfulness, interpersonal reactivity (empathy), emotion recognition, and theory of mind and significantly lower levels of cognitive impairment and lower levels of attribution style, including hostility bias intentionality bias, blame, anger bias, and aggressivity bias. They also found that the higher the levels of mindfulness, particularly the non-reactivity facet of mindfulness, the higher the levels of empathy.

 

This study is cross-sectional and has to be interpreted with caution. The results, however suggest that meditators have higher levels of social cognition. That is, that meditators are much more sensitive to others. This, in turn, improves their ability to understand and interact with others. They also suggest that meditators have a better ability to be non-reactive to what is transpiring in the present moment. This would make them better at responding empathetically to others. Hence, the study suggests that meditation practice may improve the individual’s sensitivity to others.

 

So, become more sensitive to others with meditation.

 

“Learning to communicate with empathy can go a long way toward building more positivity in your relationships and reducing your stress. If we all focused more on listening and understanding each other, the world would be a lot less stressful—and a lot happier—place to live.” – Arthur Ciamamicoli

Psychol. 10:809. doi: 10.3389/fpsyg.2019.00809

 

Research suggests that mindfulness can induce changes in the social domain, such as enhancing emotional connection to others, prosocial behavior, and empathy. However, despite growing interest in mindfulness in social psychology, very little is known about the effects of mindfulness on social cognition. Consequently, the aim of this study was to explore the relationship between mindfulness and social cognition by comparing meditators with non-meditators on several social cognition measures. A total of 60 participants (meditators, n = 30; non-meditators, n = 30) were matched on sex, age, and ethnic group, and then asked to complete the following assessment measures: Mindful Awareness Attention Scale (MAAS), Five Facet Mindfulness Questionnaire Short Form (FFMQ-SF), Interpersonal Reactivity Index (IRI), Revised Eyes Test, Hinting Task, Ambiguous Intentions and Hostility Questionnaire (AIHQ), Hospital Anxiety and Depression Scale (HADS), and Screening for Cognitive Impairment in Psychiatry (SCIP). The results showed that meditators reported higher empathy (except for the personal distress subscale), higher emotional recognition, higher theory of mind (ToM), and lower hostile attributional style/bias. The findings also demonstrated that dispositional mindfulness (both total score assessed with MAAS and mindfulness facets using the FFMQ) was associated with social cognition, although it was not equally correlated with all social cognition outcomes, and correlation patterns differ when analyses were conducted separately for meditators and non-meditators. In addition, results showed potential predictors for each social cognition variable, highlighting non-reactivity to inner experience as a key component of mindfulness in order to explain social cognition performance. In summary, the findings indicated that the meditator sample performed better on certain qualities (i.e., empathy, emotional recognition, ToM, hostile attributional style/bias) in comparison to non-meditators and, furthermore, support the notion that mindfulness is related to social cognition, which may have implications for the design of mindfulness-based approaches for use in clinical and non-clinical settings.

Improve Feedback Learning with Focused Meditation

Improve Feedback Learning with Focused Meditation

 

By John M. de Castro, Ph.D.

 

“Meditation is a powerful tool for the body and the mind; it can reduce stress and improve immune function. But can it also help us train our minds to learn faster from feedback or information acquired through past experiences?” – Jasmine Collier

 

Learning is fundamental to humans’ ability to survive and adapt in our environments. It is particularly essential in modern environments. Indeed, modern humans need to spend decades learning the knowledge and skills that are needed to be productive. Essential to the learning process is reacting to feedback from the consequences of actions. This is known as the “Law of Effect. Mindfulness is known to improve learning. So, it would seem reasonable to investigate how mindfulness training may improve the ability to respond to the feedback and learn.

 

In today’s Research News article “Meditation experience predicts negative reinforcement learning and is associated with attenuated FRN amplitude.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6420441/), Knytl and Opitz recruited healthy adults and separated them into groups who were non-meditators, novice meditators, and experienced meditators. The meditators were practitioners of focused meditation. They performed a probablistic selection task while the electroencephalogram (EEG) was recorded. Event related potentials (ERPs) were recorded in response to the presentation of the symbols.

 

In the probablistic selection task the participants were asked to select between two symbols presented randomly on a computer screen. One symbol, if selected, would produce positive feedback (10 points). Whether that symbol produced the feedback did not occur on every occasion. There were different probabilities of feedback, 20%, 30%, 40%, 60%, 70%, 80%. In the 60% case feedback would occur 6 out of every 10 times the symbol was presented. The participants were not told which symbols would produce positive feedback. They had to discover it themselves.

 

They found that non-meditators were significantly more negatively biased while focused meditators were significantly more positively biased. The non-meditators were better at not responding on trials where there was no positive feedback symbol present while the focused meditators were better at responding on trials where there was a positive feedback symbol present. In addition, they found that the more years of focused meditation experience the larger the difference.

 

In the EEG, the focused meditators had the smallest feedback related negativity (FRN) which involves a greater negative going electrical response of the frontal lobes in the event related potential (ERP) that occurred about a quarter of a second after the stimulus on positive trials than on negative trials. This response is thought to signal reinforcement occurring in the brain systems. In addition, they found that the more years of meditation experience the larger the reduction in the FRN.

 

The study is complicated and the results difficult to interpret, but they suggest that focused meditation experience makes and individual more sensitive to positive reinforcement and less sensitive to negative reinforcement. This bias is reflected in both the behavioral and event related potential data. This suggests that the demonstrated ability of focused meditation training to improve attention ability improves the ability of the meditator to detect stimuli that produce positive reinforcement. This makes meditators better at learning the feedback signals provided by the environment.

 

So, improve feedback learning with focused meditation.

 

“Humans have been meditating for over 2000 years, but the neural mechanisms of this practice are still relatively unknown. These findings demonstrate that, on a deep level, meditators respond to feedback in a more even-handed way than non-meditators, which may help to explain some of the psychological benefits they experience from the practice.” – Paul Knytl

Abstract

Focused attention meditation (FAM) practices are cognitive control exercises where meditators learn to maintain focus and attention in the face of distracting stimuli. Previous studies have shown that FAM is both activating and causing plastic changes to the mesolimbic dopamine system and some of its target structures, particularly the anterior cingulate cortex (ACC) and striatum. Feedback-based learning also depends on these systems and is known to be modulated by tonic dopamine levels. Capitalizing on previous findings that FAM practices seem to cause dopamine release, the present study shows that FAM experience predicts learning from negative feedback on a probabilistic selection task. Furthermore, meditators exhibited attenuated feedback-related negativity (FRN) as compared with nonmeditators and this effect scales with meditation experience. Given that reinforcement learning and FRN are modulated by dopamine levels, a possible explanation for our findings is that FAM practice causes persistent increases in tonic dopamine levels which scale with amount of practice, thus altering feedback processing.
