Improve Attention and Memory with Closed-Loop Digital Meditation

 

By John M. de Castro, Ph.D.

 

“The good news is that its possible to train your attention and gain the associated benefits, and practicing mindfulness offers one of the most accessible and effective approaches.” – Deborah Schoeberlein David

 

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. One of the primary effects of mindfulness training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of mindfulness training and produces improvements in thinking, reasoning, and creativity. The importance of heightened attentional ability to the individual’s ability to navigate the demands of complex modern life cannot be overstated. It helps in school, at work, in relationships, or simply driving a car. As important as attention is, it’s surprising that little is known about the mechanisms by which mindfulness improves attention.

 

There is evidence that mindfulness training improves attention by altering the brain. It appears That mindfulness training increases the size, connectivity, and activity of areas of the brain that are involved in paying attention. One way to observe the effects of meditation is to measure changes in the electroencephalogram (EEG), the rhythmic electrical activity that can be recorded from the scalp. The recorded activity can be separated into frequency bands. Theta activity consists of oscillations in the 4-8 cycles per second band and it thought to measure attention. Another method to observe attentional processing in the brain is to measure the changes in the electrical activity that occur in response to paying attention. 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 P300 response in the evoked potential (ERP) is a positive going electrical response occurring between a 1.5 to 5.0 tenths of a second following the target stimulus presentation. The P300 component is thought to reflect attentional processes.

 

In today’s Research News article “Closed-loop digital meditation improves sustained attention in young adults.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7534732/ ) Ziegler and colleagues recruited meditation-naïve young adults and randomly assigned them to a placebo control group or to receive 6 weeks of daily online breath following focused meditation training. Initially they meditated for 20 minutes but as they reported greater and greater ability to pay attention to their breath the duration of the meditation increased up to 30 minutes. The placebo control condition was engagement with an online app that was judged by participants to produce expectations equivalent to the meditation app for improvements in sustained attention and working memory. Three online aps were identified and self-selected by the participants of foreign language learning, Tai Chi practice, or logic games. The participants were measured before and after training for sustained attention, distraction filtering, working memory, and accuracy of working memory. They also recoded the electroencephalogram (EEG) during the sustained attention task and recorded the theta rhythm and the P300 evoked potentials to the attention stimuli.

 

They found that in comparison to the placebo group the meditation group had significant increases in sustained attention, distraction filtering, and working memory. In addition, they found that the greater the duration of the meditation practice achieved the greater the improvement in sustained attention. In the EEG they found that the meditation group had significant increases in attention-related EEG measures. In particular, they had increased frontal midline theta rhythm and earlier parietal P300 latencies in the evoked potentials.

 

Previous studies have shown that mindfulness practices produce improvements in attention and memory. An interesting and important difference between this research and prior research is that they employed a control condition that was demonstrated to produce the same degree of expectation in the participants for improvement in attention and memory. In other words. they controlled for participant expectancy, placebo, effects that were not controlled in the prior work. So, the improvements in attention and working memory were likely due to the meditation practice itself. Another interesting difference was that the present results were both in behavioral and brain activity measures. This demonstrates that the effects can be seen in objective, EEG and evoked potential data, and not just in behavioral responses that are more susceptible to bias.

 

So, improve attention and memory with closed-loop digital meditation.

Study Summary

 

Ziegler, D. A., Simon, A. J., Gallen, C. L., Skinner, S., Janowich, J. R., Volponi, J. J., Rolle, C. E., Mishra, J., Kornfield, J., Anguera, J. A., & Gazzaley, A. (2019). Closed-loop digital meditation improves sustained attention in young adults. Nature human behaviour, 3(7), 746–757. https://doi.org/10.1038/s41562-019-0611-9

 

Abstract

Attention is a fundamental cognitive process that is critical for essentially all aspects of higher-order cognition and real-world activities. Younger generations have deeply embraced information technology and multitasking in their personal lives, school, and the workplace, creating myriad challenges to their attention. While improving sustained attention in healthy young adults would be beneficial, enhancing this ability has proven notoriously difficult in this age group. Here we show that six-weeks of engagement with a meditation-inspired, closed-loop software program (MediTrain) delivered on mobile devices led to gains in both sustained attention and working memory in healthy young adults (n = 22). These improvements were associated with positive changes in key neural signatures of attentional control (frontal theta inter-trial coherence and parietal P3b latency), as measured by electroencephalography. Our findings suggest the utility of delivering aspects of the ancient practice of focused-attention meditation in a modern, technology-based approach and its benefits on enhancing sustained attention.

Become a Better Athlete with Mindfulness

 

By John M. de Castro, Ph.D.

 

“athletes perform better when experiencing flow and that mindfulness meditation for athletes can help them experience flow. This is really good news for high-performance coaches and athletes.” – Ertheo

 

Athletic performance requires the harmony of mind and body. Excellence is in part physical and in part psychological. That is why an entire profession of Sports Psychology has developed. “In sport psychology, competitive athletes are taught psychological strategies to better cope with a number of demanding challenges related to psychological functioning.” They use a number of techniques to enhance performance including mindfulness training. It has been shown to improve attention and concentration and emotion regulation and reduces anxiety and worry and rumination, and the physiological and psychological responses to stress. As a result, mindfulness training has been employed by athletes and even by entire teams to enhance their performance.

 

In today’s Research News article “Mindfulness Training Enhances Endurance Performance and Executive Functions in Athletes: An Event-Related Potential Study.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7474752/ ) Nien and colleagues explored the effects of mindfulness training on college athletes. They recruited healthy college athletes who had no experience with mindfulness training and randomly assigned them to either receive mindfulness training or to a wait-list control condition. Mindfulness training consisted of 2 30-minute training sessions per week for 5 weeks and included mindful breathing, mindful meditation, body scanning, mindful yoga, and mindful walking. They were measured before and after the 5-week training period for athletic endurance, cognitive function (Stroop task), and mindfulness. The Stroop Task measures attention, response speed, and behavioral inhibition.

 

To measure the nervous systems processing of information, the electroencephalogram (EEG) was recorded and evoked potentials to the stimuli onsets were measured during the Stroop Task. They focused on the N2 response in the evoked potential which is a negative going electrical response in the EEG occurring between a 2.0 to 3.5 tenths of a second following the target stimulus presentation. The N2 component is thought to reflect attentional monitoring of conflict and inhibitory control.

 

They found that in comparison to baseline and the wait-list control group, the athletes who received mindfulness training had significant increases in mindfulness, athletic endurance, and attention and behavioral inhibition accuracies on the Stroop cognitive task. They also found that the mindfulness trained athletes had significantly lower N2 responses in the evoked potential.

 

These are interesting findings but conclusions must be tempered with the knowledge that the comparison condition was passive. This opens the possibility of alternative explanations such as participant expectancy, attention, or bias effects. Nevertheless, the results suggest that mindfulness training improves the athlete’s executive function and endurance. The results of both the Stroop Task and the N2 component of the evoked potential are compatible as each measures the ability to inhibit responses in the face of informational conflict.

 

The mechanisms by which mindfulness training has these effects was not explored in the present study. But previous research has demonstrated that mindfulness training improves executive function including behavioral inhibition. Additionally, previous research has demonstrated that mindfulness training improves the physiological and psychological responses to stress. These improved responses to stress may well explain the increased athletic endurance observed in the mindfulness training athletes as endurance measures the individual’s ability to maintain function under stress.

 

So, become a better athlete with mindfulness.

 

“Focus and attention, body awareness and the ability to immerse yourself in the present moment – these are skills in both high-level athletic performance and mindfulness meditation.” – Dave Charny

Abstract

Mindfulness interventions have been linked to improved sport performance and executive functions; however, few studies have explored the effects of mindfulness on sport performance and executive functions simultaneously. This study sought to examine whether a mindfulness training program would affect both the endurance performance and executive functions of athletes. In addition, event-related potentials (ERPs) associated with the Stroop task were assessed to investigate the potential electrophysiological activation associated with the mindfulness training. Applying a quasiexperimental design, forty-six university athletes were recruited and assigned into a five-week mindfulness training program or a waiting list control group. For each participant, the mindfulness level, endurance performance assessed by a graded exercise test, executive functions assessed via Stroop task, and N2 component of ERPs were measured prior to and following the 5-week intervention. After adjusting for the preintervention scores as a covariate, it was found that the postintervention mindfulness level, exhaustion time, and Stroop task accuracy scores, regardless of task condition, of the mindfulness group were higher than those of the control group. The mindfulness group also exhibited a smaller N2 amplitude than the control group. These results suggest that the five-week mindfulness program can enhance the mindfulness level, endurance performance, and multiple cognitive functions, including executive functions, of university athletes. Mindfulness training may also reduce conflict monitoring in neural processes.

Meditate to Alter the Brain and Overcome Attention and Hyperactivity Problems Resulting from Childhood Neglect

Meditate to Alter the Brain and Overcome Attention and Hyperactivity Problems Resulting from Childhood Neglect

 

By John M. de Castro, Ph.D.

 

“Without appropriate clinical interventions, individuals exposed to relational trauma in childhood are at greater risk for difficulties in adult relationships and parenting.” At present, there is not much in the way of treatment for individual adults who have experienced childhood maltreatment: this study shows that mindfulness could help change that.” – Emily Nauman

 

“Child maltreatment is the abuse and neglect that occurs to children under 18 years of age. It includes all types of physical and/or emotional ill-treatment, sexual abuse, neglect, negligence and commercial or other exploitation, which results in actual or potential harm to the child’s health, survival, development or dignity in the context of a relationship of responsibility, trust or power.” (World Health Organization, 2016)

 

Childhood neglect is traumatic and can leave in its wake symptoms which can haunt the victims for the rest of their lives. These include cognitive impairments such as attentional difficulties, difficulty concentrating, and hyperactivity. Unfortunately, childhood neglect can continue to affect mental and physical health throughout the individual’s life. Fortunately, mindfulness training has been found to help. Indeed, mindfulness has been found to be effective for relieving trauma symptoms even in adults who were maltreated in childhood..

 

In today’s Research News article “Closed-loop digital meditation for neurocognitive and behavioral development in adolescents with childhood neglect.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7235252/) Mishra and colleagues recruited adolescents (aged 10-18 years) who had experienced childhood neglect. They were randomly assigned to either a no-treatment control condition or to receive over the internet 30 sessions over 6 weeks of 30 minutes of either breath following meditation or attention to sensory information video games. They were measured before and after training and one year later for sustained attention, attention with distractors, inattention behaviors, hyperactivity, and academic performance. They also had their brains scanned with Resting-state functional magnetic resonance imaging (rs-fMRI).

 

They found that in comparison to baseline and the no-treatment and the attention to sensory information groups, the breath following meditation group after treatment had significant increases in attentional ability, both sustained and with distractors and a significant improvement in academic performance. In addition, the breath following meditation groups had a significant decrease in hyperactivity at the 1-year follow-up. The resting-state functional magnetic resonance imaging (rs-fMRI) revealed that the greater the level of childhood neglect experienced by the adolescents the lower the functional connectivity of the dorsal anterior cingulate cortex. After treatment only the breath following meditation group had a significant increase in the functional connectivity of the dorsal anterior cingulate cortex and the greater the increase in connectivity the greater the improvements in sustained attention and hyperactivity.

 

These are interesting and potentially important findings. Childhood neglect appears to result in impairments in the connectivity of a key brain area involved in regulating attention, the dorsal anterior cingulate cortex. This could explain why neglected children have a higher likelihood of developing attention deficit hyperactivity (ADHD) disorder in adolescents. Importantly, training in breath following meditation appears to some extent reverse the loss of functional connectivity and the attentional and hyperactivity symptoms of the adolescents and result in improved performance in school. Hence, training in breath following meditation may be very helpful in preventing childhood neglect from producing ADHD in adolescents and impairing their academic performance.

 

Another important aspect of the present study was that the treatment was provided over the internet. This greatly increases its availability, convenience, and utility and reduces cost. So, the treatment can be cost effectively scaled up to treat large numbers of adolescents scattered over wide geographic regions. This makes it available to adolescents who are neither near a therapist or can afford therapy.

 

Hence, meditate to alter the brain and overcome attention and hyperactivity problems resulting from childhood neglect.

 

“The absence of emotional support in childhood can be as damaging and long-lasting as other traumas. But, because you can’t point to exactly where and when the wounding happened, it can be hard to identify and overcome it.” – Andrea Brandt

Closed-loop digital meditation for neurocognitive and behavioral development in adolescents with childhood neglect. Translational psychiatry, 10(1), 153. https://doi.org/10.1038/s41398-020-0820-z

 

Abstract

Adverse childhood experiences are linked to poor attentive behaviors during adolescence, as well as increased risk for mental health disorders in adults. However, no study has yet tested targeted interventions to optimize neurocognitive processes in this population. Here, we investigated closed-loop digital interventions in a double-blind randomized controlled study in adolescents with childhood neglect, and evaluated the outcomes using multimodal assessments of neuroimaging, cognitive, behavioral, and academic evaluations. In the primary neuroimaging results, we demonstrate that a closed-loop digital meditation intervention can strengthen functional connectivity of the dorsal anterior cingulate cortex (dACC) in the cingulo-opercular network, which is critically developing during the adolescent period. Second, this intervention enhanced sustained attention and interference-resolution abilities, and also reduced behavioral hyperactivity at a 1-year follow-up. Superior academic performance was additionally observed in adolescents who underwent the digital meditation intervention. Finally, changes in dACC functional connectivity significantly correlated with improvements in sustained attention, hyperactivity, and academic performance. This first study demonstrates that closed-loop digital meditation practice can facilitate development of important aspects of neurocognition and real-life behaviors in adolescents with early childhood neglect.

Improve Primary School Students’ Attention and Behavior with Mindfulness

 

By John M. de Castro, Ph.D.

 

“For kids who have suffered from prolonged stress or trauma, mindfulness seems to offer a way of “short-circuiting” the fight-or-flight response. It helps kids with the greatest self-regulation challenges adapt to slower, more methodical classroom settings.” – Amanda Moreno

 

Childhood is a miraculous period during which the child is dynamically absorbing information from every aspect of its environment. It is here that behaviors, knowledge, skills, and attitudes are developed that shape the individual. But what is absorbed depends on the environment. If it is replete with speech, the child will learn speech, if it is replete with trauma, the child will learn fear, if it is replete with academic skills the child will learn these, and if it is replete with interactions with others, the child will learn social skills.

 

Elementary school environments have a huge effect on development. They are also excellent times to teach children the skills to adaptively negotiate its environment. Mindfulness training in school, at all levels has been shown to have very positive effects. These include academic, cognitive, psychological, and social domains. Importantly, mindfulness training in school appears to improve the student’s self-concept. It also improves attentional ability and reduces stress, which are keys to successful learning in school. Since, what occurs in the early years of school can have such a profound, long-term effect on the child it is important to further study the impact of mindfulness training on the development of thinking skills in elementary school children.

 

In today’s Research News article “The Effect of a Mindfulness-Based Intervention on Attention, Self-Control, and Aggressiveness in Primary School Pupils.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7178275/), Suárez-García and colleagues recruited two 3rd grade primary school classes with children between the ages of 7 to 10 years. One class received 8 weekly mindfulness training sessions with 10 minutes of daily practice. At the end of the 8 weeks of training for the first class, the second class received the mindfulness training. They were measured before and after each intervention for intellectual ability and attentional ability. In addition, the teachers were asked to evaluate the children for attentional problems, self-control deficits, and aggressiveness.

 

They found that in comparison to the control classroom and the baseline the mindfulness trained children had significant reductions in attentional problems and self-control deficits. The second class after their mindfulness training also showed significant reductions in attentional problems and self-control deficits. No significant changes in aggressiveness were observed.

 

The results are similar to findings with adults that mindfulness training improves attention and self-control and that mindfulness training can be successfully implemented in schools producing improvements in attentional ability. The findings that mindfulness training in 3rd grade classrooms can also improve attention and self-control is important as these abilities are essential to the education of the students. The improvements would also contribute to better management of the classroom. Changes in academic progress were not measured. But the results suggest that the children would perform better in school after mindfulness training.

 

So, improve primary school students’ attention and behavior with mindfulness.

Abstract

The objective of this study was to examine the effect of Mindkeys Training, a mindfulness-based educational intervention, on attention, self-control, and aggressiveness in third-year primary school pupils. In order to achieve this aim, a switching replications design was used. Two groups of third year primary students (nGE1 = 40; nGE2 = 33), aged between 7 and 10 years old (M = 8.08; DT = 0.49), had the intervention at different time points, such that while one served as the experimental group, the other served as the control group. Longitudinal differences were examined in both groups, and cross-sectional differences were examined between the two groups at three time points; at the start of the study, and following the intervention with each group. To that end, measurements of problems of attention, deficits of self-control, and aggressiveness for students were obtained via a teacher rating scale. The intervention program demonstrated a positive effect on the reduction of pupils’ attention problems, deficits of self-control, and aggressiveness. The effects were greater on the cognitive variables that the intervention worked on directly (attention and self-control). Attention was the variable on which the intervention exhibited the longest term effects.

Improve Emotion Regulation and Attention with Zen Meditation

Improve Emotion Regulation and Attention with Zen Meditation

 

By John M. de Castro, Ph.D.

 

“Meditation can give you a sense of calm, peace and balance that can benefit both your emotional well-being and your overall health. And these benefits don’t end when your meditation session ends. Meditation can help carry you more calmly through your day and may help you manage symptoms of certain medical conditions.” – Mayo Clinic

 

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.

 

There is a vast array of techniques for the development of mindfulness. They include a variety of forms of meditation, yoga, mindful movements, contemplative prayer, and combinations of practices. Zen meditation has been practiced for centuries but has only recently been studied with empirical science.

 

In today’s Research News article “Zen meditation neutralizes emotional evaluation, but not implicit affective processing of words.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7029852/), Lusnig and colleagues recruited adult experienced meditators and meditation naïve participants. The meditators engaged in a 90-minute Zen meditation session while the control group watched a neutral 90-minute documentary movie. They were measured before and after the session for attention, concentration, intelligence, and personality, and performed a lexical decision task to positive and negative emotion laden words, and neutral words varying in arousal level. They also reported the emotional valence of the words from -3 as very negative to +3 as very positive.

 

They found that in comparison to baseline and the comparison group after the single meditation session, the meditators rated the valence of the emotion laden words as more neutral and detected words significantly faster. The researchers interpreted these findings as indicative of meditation increasing attention (faster response times) and decreasing emotionality (neutralized valence ratings).

 

These findings are not surprising in that previous research has demonstrated that mindfulness practices improve attention and improve emotion regulation. They are surprising, however, in demonstrating that a single meditation session with experienced meditators is sufficient to activate these effects. It would have been interesting to also look at the effects of a meditation session on the meditation naïve participants to determine if the effects were due to meditation in general or to a difference in the effects of meditation on experienced versus naïve meditators.

 

So, improve emotion regulation and attention with Zen meditation.

 

“mindfulness meditation preaches accepting and letting go of negative emotions. Practicing this sort of behavior, scientists say, seems to improve meditators’ ability to control their emotions even when they’re not meditating. It seems to give meditators more emotional ballast, making them less easily swept up in the ups and downs of the present.” – Joseph Stromberg

Abstract

There is ample evidence that meditation can regulate emotions. It is questionable, however, whether meditation can down-regulate sensitivity to emotional experience in high-level cognitive representations such as words. The present study shows that adept Zen meditators rated the emotional valence of (low-arousal) positive and (high- and low-arousal) negative nouns significantly more neutral after a meditation session, while there was no change of valence ratings after a comparison intervention in the comparison group. Because the Zen group provided greater “openness to experience” and lower „need for achievement and performance” in the “Big Five” personality assessment, we used these scores as covariates for all analyses. We found no differential emotion effects of Zen meditation during lexical decision, but we replicated the slow-down of low-arousal negative words during lexical decision in both groups. Interestingly, Zen meditation elicited a global facilitation of all response times, which we discuss in terms of increased attentional resources after meditation.

Enhance Attention and Attentional Brain Systems with Meditation

Enhance Attention and Attentional Brain Systems with Meditation

 

By John M. de Castro, Ph.D.

 

“intensive and continued meditation practice is associated with enduring improvements in sustained attention,” – Anthony Zanesco

 

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. One of the primary effects of mindfulness training is an improvement in the ability to pay attention to the task at hand and ignore interfering stimuli. This is an important consequence of mindfulness training and produces improvements in thinking, reasoning, and creativity. The importance of heightened attentional ability to the individual’s ability to navigate the demands of complex modern life cannot be overstated. It helps in school, at work, in relationships, or simply driving a car. As important as attention is, it’s surprising that little is known about the mechanisms by which mindfulness improves attention.

 

There is evidence that mindfulness training improves attention by altering the brain. It appears That mindfulness training increases the size, connectivity, and activity of areas of the brain that are involved in paying attention. In today’s Research News article “Enhanced Attentional Network by Short-Term Intensive Meditation.” (See summary below or view the full text of the study at: https://www.frontiersin.org/articles/10.3389/fpsyg.2019.03073/full?utm_source=F-AAE&utm_medium=EMLF&utm_campaign=MRK_1245141_69_Psycho_20200213_arts_A), Kwak and colleagues recruited healthy meditation naïve adults and randomly assigned them to a 4 -day 3-night structured residential retreat of either meditation practice (19 hours total practice) or relaxation.

 

Before and after the retreat the participants underwent functional Magnetic Resonance Imaging (fMRI) of their brains. While they were in the scanner attention was measured with an attention network task. This included a flanker task and a temporal and spatial cueing task. These tasks measure 3 attentional processes, alerting, orienting, and executive control.

 

They found that after the meditation retreat but not the relaxation retreat there was a significant improvement in executive attentional control. The fMRI revealed that the meditation retreat group in comparison to baseline and the relaxation group had significant increases in activity in the dorsolateral prefrontal cortex and anterior cingulate cortex, both components of the so-called executive control network. They also found that the better the performance on the executive attentional control task, the greater the increase in activity in the anterior cingulate cortex. Additionally, they found that the meditation group had significant increases in the activity of the so called attentional orienting network in the brain including the dorsolateral prefrontal cortex, superior and inferior frontal gyrus, frontal eye fields, and anterior cingulate cortex. Finally, they found that the meditation group had significant increases in the activity of the so-called attentional alerting network in the brain including the superior temporal gyrus and the insula.

 

The results demonstrate that an intensive meditation retreat significantly improves attentional processes. This can be seen both behaviorally and neurologically. Behaviorally there was improvement in the executive attentional control while neurologically there were increases in the executive, orienting, and alerting attentional networks. These results suggest that meditation practice alters to brain systems underlying attention resulting in improved attentional ability. These changes may underlie many of the benefits produced by meditation practice.

 

So, enhance attention and attentional brain systems with meditation.

 

“With more distractions at your fingertips than ever before, focused attention has become “an endangered species.” Luckily, . . . as little as 10 minutes of meditation a day can help turn the tide, and these benefits can be observed from the moment a person begins their practice.” – Nicole Bayes-Fleming

While recent studies have suggested behavioral effects of short-term meditation on the executive attentional functions, functional changes in the neural correlates of attentional networks after short-term meditation have been unspecified. Here, we conducted a randomized control trial to investigate the effects of a 4-day intensive meditation on the neural correlates of three attentional functions: alerting, orienting, and executive attention. Twenty-three participants in meditation practice and 14 participants in a relaxation retreat group performed attention network test (ANT) during functional magnetic resonance imaging both before and immediately after intervention. The meditation group showed significantly improved behavioral performance in the executive control network in ANT after the intervention. Moreover, neural activities in the executive control network, namely, the anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC), were also significantly increased during the ANT after meditation. Interestingly, neural activity in the right ACC was significantly predicted by behavioral conflict levels in each individual in the meditation group, indicating significant effects of the program on the executive control network. Moreover, brain regions associated with the alerting and orienting networks also showed enhanced activity during the ANT after the meditation. Our study provides novel evidence on the enhancement of the attentional networks at the neural level via short-term meditation. We also suggest that short-term meditation may be beneficial to individuals at high risk of cognitive deficits by improving neural mechanisms of attention.

Different Meditation Types Produce Different Effects on Attention, Compassion, and Theory of Mind

 

By John M. de Castro, Ph.D.

 

“The mental procedures used by various traditions and schools of meditation are fairly dissimilar. And recent scientific research has verified that these different ways of meditating activate different areas in our brain.” – Trancendental Meditation

 

Meditation training has been shown to improve health and well-being. It has also been found to be effective for a large array of medical and psychiatric conditions, either stand-alone or in combination with more traditional therapies. As a result, meditation training has been called the third wave of therapies. One problem with understanding meditation effects is that there are, a wide variety of meditation techniques and it is not known which work best for affecting different psychological areas.

 

There are a number of different types of meditation. Classically they’ve been characterized on a continuum with the degree and type of attentional focus. In focused attention meditation, the individual practices paying attention to a single meditation object. In open monitoring meditation, the individual opens up awareness to everything that’s being experienced including thoughts regardless of its origin. In Loving Kindness Meditation the individual systematically pictures different individuals from self, to close friends, to enemies and wishes them happiness, well-being, safety, peace, and ease of well-being.

 

In today’s Research News article “Differential benefits of mental training types for attention, compassion, and theory of mind.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6891878/), Trautwein and colleagues recruited healthy adults and assigned them to one of three conditions; presence, affect, and perspective training. Each condition consisted of a 3-day retreat followed by once a week 2-hour training session for 13 weeks along with daily home practice. The presence training focused on attention to the present moment and contained focused breath meditation, walking meditation, and body scan practices. The affect training focused on developing an “accepting, kind, and compassionate stance towards oneself and others” and contained loving kindness meditation, forgiveness meditation, and affect dyad practices. The perspective training focused on the central role that thoughts play in our lives and contained meditation of observing thoughts coming and going and perspective dyads. They were measured before and after training with a cued flanker task measuring executive control and attentional reorienting and a Theory of Mind and Social Cognition task measuring social cognitive and affective functions including compassion. Theory of mind refers to the ability to observe self-awareness in self and others.

 

They found that in comparison to baseline and the other modules, the presence training significantly improved executive control and attentional reorienting. They also found that the affect and perspective training produced significant improvements in the socio-emotional dimension of compassion. Finally, they found that perspective training produced significantly higher scores on Theory of Mind (understanding beliefs, desires, and needs of others). Hence the three different forms of mindfulness training affected different abilities.

 

The findings suggest that training on present moment awareness affects attentional abilities but not socio-emotional and theory of mind abilities. On the other hand, affect training affects socio-emotional abilities including compassion but not attention or theory of mind abilities. Finally, the results suggest that perspective training affects socio-emotional and theory of mind abilities but not attentional abilities. These findings suggest that different mindfulness training programs should be employed to target specific problem areas for the participant. They also suggest that incorporating components from presence, affect, and perspective training may produce a training package that enhances abilities in all domains.

 

So, different meditation types produce different effects on attention, compassion, and theory of mind.

 

“Meditation is a simple strategy that can help obtain better health and a happier life. It takes time to master, as does any other skill. If a person sticks with it and is willing to experiment with the different methods, they are more likely to discover a meditation style that suits them.” – Zawn Villines

Study Summary

Abstract

Mindfulness- and, more generally, meditation-based interventions increasingly gain popularity, effectively promoting cognitive, affective, and social capacities. It is unclear, however, if different types of practice have the same or specific effects on mental functioning. Here we tested three consecutive three-month training modules aimed at cultivating either attention, socio-affective qualities (such as compassion), or socio-cognitive skills (such as theory of mind), in three training cohorts and a retest control cohort (N = 332). While attentional performance improved most consistently after attention training, compassion increased most after socio-affective training and theory of mind partially improved after socio-cognitive training. These results show that specific mental training practices are needed to induce plasticity in different domains of mental functioning, providing a foundation for evidence-based development of more targeted interventions adapted to the needs of different education, labor, and health settings.

Reduce Anxiety and Improve Attention in Pre-Teens with Yogic Breathing

Reduce Anxiety and Improve Attention in Pre-Teens with Yogic Breathing

 

By John M. de Castro, Ph.D.

 

“Pranayama is an incredibly effective, important tool to teach children so they can control their energy, their mood, and their impulses.” – Amanda James

 

Breathing is essential for life and generally occurs automatically. It’s easy to take for granted as it’s been there our entire lives. Nevertheless, we become more aware of it when it varies with circumstances, such as when we exercise and also in emotional states, especially fear and anxiety. But we rarely notice it during everyday ongoing life. Yet, its characteristics are associated with our state of well-being. Slow deep breathing is characteristic of a healthy relaxed state. Breathing exercises are common in yoga practices and have been found to have a number of beneficial effects.

 

The Pre-teen years are transitional between childhood and adolescence. What happens here and what is learned can have a huge impact on the child’s ability to navigate the difficult years of adolescence. It is not known whether training in yogic breathing techniques can be beneficial for pre-teens.

 

In today’s Research News article “Immediate Effect of a Yoga Breathing Practice on Attention and Anxiety in Pre-Teen Children.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6678429/), Telles and colleagues recruited healthy pre-teen children (11-12 years of age) who practiced yoga and yogic breathing exercises and randomly assigned them to one of 3 orders of 3 interventions; high frequency yogic breathing, breath awareness, and quiet sitting practiced on successive days. The breathing exercises were practiced at school for 3 3.5-minute periods followed by 1-minute rest. They were measured before and after each session for anxiety and selective attention.

 

They found that there was a significant decrease in anxiety after all 3 interventions. After high frequency yogic breathing there was a significant increase in selective attention, while after breath awareness there was a significant increase in selective attention errors.

 

The reduction in anxiety cannot be definitively ascribed to the yogic exercises as quiet sitting also reduces anxiety. Anxiety reduction may also be due to relief for having finished the task as there was a reduction regardless of task. High frequency yogic breathing is known to produce physiological activation, increasing heart rate and blood pressure. This activation may be responsible for the improved selective attention. On the other hand, breath awareness practice tends to produce relaxation. It is possible that this relaxation reduces vigilance and increases errors in selective attention.

 

There is a need for more research on yogic breathing and its effects on anxiety levels to ascertain if the reduction in anxiety are due to contaminants such as placebo effects or relaxation after task completion. It is important to reduce anxiety in pre-teens as this is a difficult time and high levels of anxiety can interfere with the child’s ability to cope with the challenges. Also, improved selective attention with high frequency yogic breathing may help the pre-teens in their academic endeavors.

 

So, reduce anxiety and improve attention in pre-teens with yogic breathing.

 

“kids love working with the breath!! There is so much fun to be had with breathing exercises. They find inner strength and peace, it uplifts them, calms them, and teaches them how to focus in nerve-wracking or anxiety-inducing situations.” – Joanne Moules

Study Summary

 

Telles, S., Gupta, R. K., Gandharva, K., Vishwakarma, B., Kala, N., & Balkrishna, A. (2019). Immediate Effect of a Yoga Breathing Practice on Attention and Anxiety in Pre-Teen Children. Children (Basel, Switzerland), 6(7), 84. doi:10.3390/children6070084

 

Abstract

Pre-teen children face stressors related to their transition from childhood to adolescence, with a simultaneous increase in academic pressure. The present study compared the immediate effects of 18 min of (i) high frequency yoga breathing with (ii) yoga-based breath awareness and (iii) sitting quietly, on (a) attention and (b) anxiety, in 61 pre-teen children (aged between 11 and 12 years; 25 girls). Attention was assessed using a six letter cancellation task and Spielberger’s State Trait Anxiety Inventory STAI-S was used to measure anxiety before and after the three practices, practiced on separate days. Repeated measures ANOVA, followed by Bonferroni adjusted post-hoc analyses showed an increase in total attempts and net scores after high frequency yoga breathing (p < 0.05), while wrong attempts increased after yoga based breath awareness (p < 0.05). Anxiety decreased comparably after all three interventions. The 25 girls in the group had the same trend of results as the whole group with respect to the attention-based cancellation task, while boys showed no, how since change. For both girls and boys, anxiety decreased after all three 18min interventions. The results suggest that high frequency yoga breathing could be a short, useful school based practice to improve attention and reduce anxiety.

Improve Attention Deficit Hyperactivity Disorder (ADHD) Symptoms in Children with Yoga

Improve Attention Deficit Hyperactivity Disorder (ADHD) Symptoms in Children with Yoga

 

By John M. de Castro, Ph.D.

 

“research reports that yoga may help relieve attention-deficit hyperactivity disorder (ADHD) in children.” – Elaine Gavalas

 

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. Yoga is both an exercise and a mindfulness practice. This could be particularly attractive for kids with ADHD.

 

In today’s Research News article “Effects of Yoga on Attention, Impulsivity, and Hyperactivity in Preschool-Aged Children with Attention-Deficit Hyperactivity Disorder Symptoms.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5871620/), Cohen and colleagues recruited preschool children (3-5 years of age) who had at least 4 symptoms of Attention Deficit Hyperactivity Disorder (ADHD). They were randomly assigned to either 6 weeks of Yoga practice or a wait-list control condition. Yoga practice consisted of breathing exercises and poses and occurred twice a week at school in a group setting for 30 minutes and on other days at home guided by a DVD. Before and after the intervention and 6 weeks and 3 months later the parents and teachers completed measures of the children’s ADHD symptoms, emotional symptoms, conduct problems, peer problems, hyperactivity/inattention and prosocial behaviors. The children were also directly measured for attention in a computer-based test and for heart rate variability.

 

They found that for children with high Attention Deficit Hyperactivity Disorder (ADHD) symptom scores, yoga practice produced significant reductions in inattention and hyperactivity/inattention ratings by the parents. On the attention task, after the yoga intervention the children had significantly improved attention but also significantly higher distractibility. These findings were maintained at follow-up.

 

The results suggest that yoga practice is particularly beneficial for children who are high in Attention Deficit Hyperactivity Disorder (ADHD) symptoms improving their attentional ability and hyperactivity. These findings require further investigation to look closer at students with lower ADHD scores. But, they suggest that yoga practice may be beneficial in treating ADHD  in preschool children. Intervening this early in development may help to prevent ADHD development and/or prevent its transition into adulthood.

 

So, improve attention deficit hyperactivity disorder (ADHD) symptoms in children with yoga.

 

“Pairing a hyperactive child with a quiet, slow form of exercise may sound counterintuitive and even disastrous, but it turns out yoga can be incredibly helpful for children with attention deficit hyperactivity disorder (ADHD).” – Dennis Thompson

Abstract

Objective

Behavioral therapies are first line treatments for preschoolers with ADHD. Studies support yoga as an intervention for school age children with ADHD; this study evaluated the effects of yoga in preschoolers on parent and teacher rated attention/challenging behaviors; attentional control (KiTAP); and heart rate variability (HRV).

Methods

This randomized waitlist-controlled trial tested a 6-week yoga intervention in preschoolers with ≥ 4 ADHD symptoms on the ADHD Rating Scale-IV Preschool Version. Group 1 (n=12) practiced yoga first; Group 2 (n=11) practiced yoga second. We collected data at four time points: baseline, T1 (6 wk), T2 (12 wk), follow-up (3 mo after T2).

Results

At baseline, there were no significant differences between Group 1 and 2 on any measure. At T1, Group 1 had faster reaction times on the KiTAP Go/No go task (p=.01, 95% CI: −371.1, −59.1, d=−1.7), fewer Distractibility errors of omission (p=.009, 95% CI: −14.2, −2.3, d=−1.5), but more commission errors (p=.02, 95% CI:1.4, 14.8, d=1.3) than Group 2. Children in Group 1 with more severe symptoms at baseline showed improvement at T1 not seen in Group 2 on parent-rated Strengths and Difficulties Questionnaire hyperactivity-inattention (β=−2.1, p=.04, 95% CI: −4.0, −0.1) and inattention on the ADHD Rating Scale (β=−4.4, p=.02, 95% CI: −7.9, −0.9). HRV measures did not differ between groups.

Conclusions

Yoga was associated with modest improvements on an objective measure of attention (KiTAP) and selective improvements on parent ratings. Yoga may be a promising treatment for ADHD symptoms in preschoolers.

Improve the Brain’s Attentional Networks with Mindfulness

Improve the Brain’s Attentional Networks with Mindfulness

 

By John M. de Castro, Ph.D.

 

“MBSR and RR body scans both induced a common increased functional connectivity between the brain’s ventromedial prefrontal cortex, which plays a role in attention.” – GORAMA

 

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 area. and have found that meditation practice appears to mold and change the brain, producing psychological, physical, and spiritual benefits. These brain changes with mindfulness practice are important and need to be further investigates.

 

In today’s Research News article “Mindfulness-Based Stress Reduction-related changes in posterior cingulate resting brain connectivity.” (See summary below or view the full text of the study at: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6778831/), Kral and colleagues recruited healthy meditation-naïve adults and randomly assigned them to 8 weeks of Mindfulness-Based Stress Reduction (MBSR) program, 8 weeks of a Health Education Program, or to a wait-list control condition. The MBSR program consisted of 8 weekly group sessions involving meditation, yoga, body scan, and discussion. The participants were also encouraged to perform daily practice at home. The amount of home practice time was recorded. Before and after the 8-week intervention they were measured for emotional styles and participated in 14 days of experience sampling with 6 to 8 prompts per day via cellphone to indicate attention to task or mind wandering. They also underwent brain scanning with functional Magnetic Resonance Imaging (fMRI) before and after the intervention and 5.5 months later.

 

They found that in comparison to baseline and the health education and wait-list control groups, the participants who underwent the Mindfulness-Based Stress Reduction (MBSR) program had a significant increase in the functional connectivity between the posterior cingulate cortex and the dorsomedial prefrontal cortex. They also found that the higher the self-reported attention levels and the greater the number of days of practice the MBSR participants engaged in, the greater the increase in functional connectivity. The connectivity increases and the relationships with attention and practice were no longer significant at the 5.5-month follow-up. There were no significant changes in mind-wandering.

 

These results are interesting and suggest that participation in the Mindfulness-Based Stress Reduction (MBSR) program produces short-term changes in the brain’s system that underlies executive function and attention (the posterior cingulate cortex and the dorsomedial prefrontal cortex). The results further suggest that the amount of change in the brain system is associated with attentional changes and the amount of practice.

 

That mindfulness training in general and Mindfulness-Based Stress Reduction (MBSR) in particular improves attention and the neural systems underlying attention and executive function have been previously demonstrated. The present study demonstrates that these changes are related to the amounts of continuing practice suggesting the importance of practice outside of formal training sessions.

 

So, improve the brain’s attentional networks with mindfulness.

 

“mindfulness meditation decreases activity in the part of the brain that is in charge of mind-wandering and self-centeredness. Although we all struggle with taming that Monkey Mind, meditators are better at snapping out of it when the brain gets into a cycle of overthinking or negativity.” –  Jaime Carlo-Casellas

Abstract

Mindfulness meditation training has been shown to increase resting-state functional connectivity between nodes of the frontoparietal executive control network (dorsolateral prefrontal cortex [DLPFC]) and the default mode network (posterior cingulate cortex [PCC]). We investigated whether these effects generalized to a Mindfulness-Based Stress Reduction (MBSR) course and tested for structural and behaviorally relevant consequences of change in connectivity. Healthy, meditation-naïve adults were randomized to either MBSR (N = 48), an active (N = 47) or waitlist (N = 45) control group. Participants completed behavioral testing, resting-state fMRI scans and diffusion tensor scans at pre-randomization (T1), post-intervention (T2) and ~5.5 months later (T3). We found increased T2–T1 PCC–DLPFC resting connectivity for MBSR relative to control groups. Although these effects did not persist through long-term follow-up (T3–T1), MBSR participants showed a significantly stronger relationship between days of practice (T1 to T3) and increased PCC–DLPFC resting connectivity than participants in the active control group. Increased PCC–DLPFC resting connectivity in MBSR participants was associated with increased microstructural connectivity of a white matter tract connecting these regions and increased self-reported attention. These data show that MBSR increases PCC–DLPFC resting connectivity, which is related to increased practice time, attention and structural connectivity.
