Improving creativity performance by short-term meditation

Effect of a Plant-Based Nootropic Supplement on Perceptual Decision-Making and Brain Network Interdependencies: A Randomised, Double-Blinded, and Placebo-Controlled Study

BACKGROUND

Natural nootropic compounds are evidenced to restore brain function in clinical and older populations and are purported to enhance cognitive abilities in healthy cohorts. This study aimed to provide neurocomputational insight into the discrepancies between the remarkable self-reports and growing interest in nootropics among healthy adults and the inconclusive performance-enhancing effects found in the literature.

METHODS

Towards this end, we devised a randomised, double-blinded, and placebo-controlled study where participants performed a visual categorisation task prior to and following 60 days of supplementation with a plant-based nootropic, while electroencephalographic (EEG) signals were concurrently captured.

RESULTS

We found that although no improvements in choice accuracy or reaction times were observed, the application of multivariate information-theoretic measures to the EEG source space showed broadband increases in similar and complementary interdependencies across brain networks of various spatial scales. These changes not only resulted in localised increases in the redundancy among brain network interactions but also more significant and widespread increases in synergy, especially within the delta frequency band.

CONCLUSIONS

Our findings suggest that natural nootropics can improve overall brain network cohesion and energetic efficiency, computationally demonstrating the beneficial effects of natural nootropics on brain health. However, these effects could not be related to enhanced rapid perceptual decision-making performance in a healthy adult sample. Future research investigating these specific compounds as cognitive enhancers in healthy populations should focus on complex cognition in deliberative tasks (e.g., creativity, learning) and over longer supplementation durations.

The Effectiveness of Mindfulness in the Treatment of Methamphetamine Addiction Symptoms: Does Neuroplasticity Play a Role?

INTRODUCTION

Methamphetamine is a highly stimulating psychoactive drug that causes life-threatening addictions and affects millions of people around the world. Its effects on the brain are complex and include disturbances in the neurotransmitter systems and neurotoxicity. There are several known treatment methods, but their effectiveness is moderate. It must be emphasised that no drugs have been approved for treatment. For this reason, there is an urgent need to develop new, effective, and safe treatments for methamphetamine. One of the potential treatments is mindfulness meditation. In recent years, this technique has been researched extensively in the context of many neurological and psychiatric disorders.

METHODS

This review explores the use of mindfulness in the treatment of methamphetamine addiction. Searches were conducted in the PubMed/Medline, Research Gate, and Cochrane databases.

RESULTS

Ten studies were identified that used mindfulness-based interventions in the treatment of methamphetamine addiction. The results show that mindfulness is an effective form of reducing hunger, risk of relapses, stress indicators, depression, and aggression, alone or in combination with transcranial direct current stimulation (tDCS). Mindfulness also improved the cognitive function in addicts. The included studies used only behavioural measures. The potential mechanisms of mindfulness in addiction were explained, and it was proposed that it can induce neuroplasticity, alleviating the symptoms of addiction.

CONCLUSIONS

Evidence from the studies suggest that mindfulness may be an effective treatment option for methamphetamine addiction, used alone or in combination with tDCS. However, further high-quality research is required to establish the role of this treatment option in this field. The use of neuroimaging and neurophysiological measures is fundamental to understand the mechanisms of mindfulness.

A meta-analytical review of the impact of mindfulness on creativity: Framing current lines of research and defining moderator variables

Findings relating to the impact of mindfulness interventions on creative performance remain inconsistent, perhaps because of discrepancies between study designs, including variability in the length of mindfulness interventions, the absence of control groups or the tendencies to explore creativity as one unitary construct. To derive a clearer understanding of the impact that mindfulness interventions may exert on creative performance, two meta-analytical reviews were conducted, drawing respectively on studies using a control group design (n = 20) and studies using a pretest-posttest design (n = 17). A positive effect was identified between mindfulness and creativity, both for control group designs (d = 0.42, 95% CIs [0.29, 0.54]) and pretest-posttest designs (d = 0.59, 95% CIs [0.38, 0.81]). Subgroup analysis revealed that intervention length, creativity task (i.e., divergent vs. convergent thinking tasks) and control group type, were significant moderators for control group studies, whereas only intervention length was a significant moderator for pretest-posttest studies. Overall, the findings support the use of mindfulness as a tool to enhance creative performance, with more advantageous outcomes for convergent as opposed to divergent thinking tasks. We discuss the implications of study design and intervention length as key factors of relevance to future research aimed at advancing theoretical accounts of the relationship between mindfulness and creativity.

Ethics and Meditation: A New Educational Combination to Boost Verbal Creativity and Sense of Responsibility

Both creativity and responsibility are important higher-order skills to develop to meet the challenges of the Anthropocene, and both are related to attentional states of consciousness and to ethics. Meditation is a set of practices that trains attentional and emotional regulation. A few studies have shown that different kinds of meditation can foster different kinds of creative thinking, and others have begun to investigate the effect of the combination of meditation and ethics on ethical characteristics (but not yet on creativity or precisely on responsibility, so far). Here, we present a nonrandomized trial with an active control group among second-year science university students (n = 84) to test the effect of the secular Meditation-Based Ethics of Responsibility (MBER) program on creative potential, self-reported awareness, and sense of one's own responsibility. The results show a large effect of the program on sense of one's own responsibility and convergent and divergent creative writing tasks, both in conceptual-semantic and engineering-like verbal ideation. They also suggest that convergent conceptual-semantic thinking might moderate the effect of the MBER program on the awareness and sense of one's own responsibility. This work opens up new research and educational perspectives linked to necessary behavioral changes in the Anthropocene.

The Relationships of Creative Coping and College Students' Achievement Emotions and Academic Stress: The Mediating Role of Psychological Capital

Creative coping is the use of creativity as a positive strategy when facing stress. The existing empirical investigation of creative coping is scarce, particularly in the field of educational psychology. The present study aims to explore the relationships of college students' creative coping and their achievement emotions and academic stress as well as the underlying mechanism. The sample included 780 Chinese college students. The Creative Coping Scale, Positive Psychological Capital Questionnaire, Learning Stress Inventory for College Students, and the short version of the Achievement Emotions Questionnaire were used. Statistical results showed that creative coping was positively related with students' positive achievement emotions and negatively related with negative achievement emotions, but insignificantly with academic stress. Moreover, psychological capital played a mediating role in the relationship between creative coping and achievement emotions and in the relationship between creative coping and academic stress with a suppression effect.

Effect of virtual group EcoMeditation on psychological conditions and flow states

Background

A plethora of literature has delineated the therapeutic benefits of meditation practice on psychological functioning. A novel meditative practice, EcoMeditation, includes elements of four evidence-based techniques: The Quick Coherence Technique for regulating heart rate variability (HRV), Emotional Freedom Techniques (EFT), mindfulness, and neurofeedback.

Objectives

Changes in psychological symptoms, including anxiety, depression, posttraumatic stress, pain, and happiness were measured following a one-day virtual EcoMeditation training workshop. The current study extended on previous literature by adding measures of transcendent experiences and flow states.

Methods

Participants were drawn from a convenience sample of 151 participants (130 female, 21 male) aged between 26 to 71 years (M = 45.1, SD = 9.19) attending a one-day virtual EcoMeditation workshop. They were assessed pre-workshop, post-workshop, and at 3-months follow-up.

Results

Post-workshop results (N = 111) indicated a significant reduction in anxiety (−42.3%, p < 0.001), depression (−37.5%, p < 0.001), posttraumatic stress (−13.0%, p < 0.001), and pain (−63.2%, p < 0.001) Likert mean scores when compared to pre-workshop. There was also a significant increase in happiness (+111.1%, p < 0.001), flow states (+17.4%, p < 0.001), and transcendent experiences (+18.5%, p < 0.001). At 3-months follow-up, a one-way repeated measures ANOVA (N = 72) found significant decreases in anxiety, depression, and pain symptoms between pre-test and post-test, as well between pre-test and follow-up. Flow, happiness, and transcendent experiences increased significantly between pre-test and post-test, as well as between pre-test and follow-up, with over 71% of participants experiencing clinically significant improvements. Significant reductions in posttraumatic stress and depression symptoms between pre-test and follow-up were also noted.

Conclusion

EcoMeditation is associated with significant improvements in psychological conditions such as anxiety, depression, pain, and posttraumatic stress. EcoMeditation was also shown to enhance flow states and transcendent experiences. The benefits identified were similar to those found in the existing literature and provide support for the use of EcoMeditation as an effective stress reduction method that improves psychological symptoms and enhances transcendent states.

The biological dimensions of transcendent states: A randomized controlled trial

This study evaluated the biological dimension of meditation and self-transcendent states. A convenience sample of 513 participants was drawn from attendees at a 4-day guided meditation workshop. Half were randomly assigned to an active placebo control intervention. All were assessed on a variety of measures, both psychological [anxiety, pain, posttraumatic stress disorder (PTSD), positive emotions, and transcendent states], and physiological (physical functioning). Additional biological assessments including salivary immunoglobulin-A (SIgA), cortisol, and Quantitative Electroencephalography (qEEG) were obtained from subset of the Experimental group (N = 117). No significant difference in psychological symptoms or positive emotions was observed between Experimental and placebo groups at baseline. At post-test, significant improvements were noted in the Experimental group, including a 49.5% median increase in SIgA (p = 0.01), though cortisol remained unchanged. qEEG z-score analysis identified sustained stress reduction, including delta frequency band amplitude increases, high beta decreases, and faster acquisition of sustained alpha states (all p < 0.001). Psychological symptoms also improved on all measures. At 6-month follow-up (N = 140), PTSD and somatic symptoms significantly improved from baseline, and post-test versus 6-month follow-up results indicated significant increases in happiness and spiritual and physical oneness, along with decreases in depressive symptoms. These findings suggest that autonomic self-regulation and transcendent states may be measured in both biological and psychological dimensions and are associated with pervasive health benefits.

Propensity or diversity? Investigating how mind wandering influences the incubation effect of creativity

Mind wandering has been argued to be beneficial for breaking through mental impasses, which leads to better creative performance upon a second attempt (i.e., the incubation effect). However, the evidence is inconsistent. Different from the propensity for mind wandering that has been the focus of past studies, in this study we further examined the role of diversity (i.e., non-repetitiveness of mind wandering respective to its content) and types of mind wandering along the dimensions of intentionality and awareness during incubation when engaging in a 0-back task (a mind wandering-prone condition) and a focused-breathing practice (a mindfulness-induced condition). We proposed that diversity rather than the propensity for mind wandering was crucial for post-incubation divergent creativity and that mindfulness induction would be a more effective way to elicit the incubation effect because it should result in fewer but more diverse mind-wandering incidents than engaging in a mind wandering-prone task. We conducted an experiment with a between-participant variable (incubation tasks: mind wandering-prone, mindfulness-induced, and no incubation). As predicted, the mindfulness-induced group (N = 30) outperformed the control group (N = 31) on flexibility for the unusual uses task measuring divergent thinking after incubation, but the mind wandering-prone group (N = 29) did not outperform the control group. In addition, the diversity of mind wandering and the tendency toward intentional mind wandering predicted the magnitude of incubation effects on flexibility and originality, respectively. Theoretical and practical implications are discussed.

[Investigacion de mindfulness en neurociencia cognitiva]

Mindfulness is a term that has become part of our society's vocabulary and its practice has become firmly established in educational, therapeutic and clinical contexts and as a tool for fostering well-being and personal growth. In this article we review the most relevant research conducted on mindfulness in cognitive neuroscience, classifying it in three broad areas: a) differential changes in default network activity due to the practice of mindfulness; b) functional or structural changes in the attentional network, and c) functional or structural changes in the frontal limbic network and the amygdala, related to emotion regulation. There is enough evidence in the literature to affirm the effect of mindfulness practice on the brain, but we still need to produce better experimental designs that allow us to find the mechanisms of action underlying specific practices.

The Impact of Mindfulness Meditation on the Wandering Mind: a Systematic Review

Through the practice of Mindfulness Meditation (MM), meditators become familiar with the observation of ongoing spontaneous thoughts, while maintaining an attitude of openness and equanimity. The aim of this systematic review is to present a synthesis of available findings of the short and long-term effects of MM on mind wandering (MW). We included studies that considered both first-person and behavioral/physiological measures of MW. The search resulted in 2035 papers, 24 of which were eligible. Reviewed studies revealed a high heterogeneity in designs, outcome measures and interventions. Most of the pre-post intervention studies showed that a protracted practice of MM (at least 2 weeks) reduced MW, limiting its negative effects on different cognitive tasks. Cross-sectional studies highlighted differences between expert meditators and naïve individuals: meditators self-reported less MW and showed decreased Default Mode Network activity, during meditation and resting-state. Further studies are needed to replicate available findings and to more deeply explore how MW is influenced by meditation, also considering its qualitative characteristics that remain largely unexplored.

Age-Related Differential Effects of School-Based Sitting and Movement Meditation on Creativity and Spatial Cognition: A Pilot Study

Psychophysical well-being can be supported during development by the integration of extra-curricular activities in scholastic settings. These activities can be implemented in different forms, ranging from physical activities to sitting meditation practices. Considering that both such activities are thought to affect children’s psychophysical development, a movement-based meditation that combines the two approaches−in the form of a short daily activity−could represent a powerful tool to promote healthy physical and mental development. Consequently, the current pilot study aimed to examine the effect of short daily school-based sitting and movement meditation trainings on creativity and spatial cognition. Utilizing a crossover design, we evaluated their feasibility and efficacy at different ages among children (n = 50) in 5th to 8th grade. We observed that 5 weeks of daily training in sitting and movement meditation techniques improved children’s cognition differently. Specifically, younger children showed greater creativity and better spatial cognition following the movement-based meditation, while older children showed greater enhancement in these areas following sitting meditation training. This suggests that training can affect children’s cognition differently depending on their developmental stage. We discuss these results within the framework of embodied and grounded cognition theories. Information on feasibility and age-related effect sizes derived from the current study paves the way for future well-powered larger-scale efficacy studies on different forms of school-based interventions to cognitive development promotion.

Effects of aerobic exercise, traditional Chinese exercises, and meditation on depressive symptoms of college student: A meta-analysis of randomized controlled trials

BACKGROUND

Non-pharmacological intervention methods such as rehabilitation training or psychological treatment are mostly used in the treatment of depression owing to the limitation of adverse reactions such as drug treatment. However, the best non-pharmacological treatment strategy for depression in college students is unclear. Therefore, it is significant to discover non-drug intervention methods that can improve the depression symptoms of college students.

METHOD

Electronic databases as of Sep 15, 2019, were searched, and reference lists and pharmaceutical dossiers were reviewed to detect published and unpublished studies from the date of their inception to Sep 15, 2019. With document quality evaluations and data extraction, Meta-Analysis was performed using a random effect model to evaluate the intervention effect of the aerobic exercise, traditional Chinese exercises, and meditation.

RESULTS

A total of 44 original studies were included. The random effect model was used to combine the effect values with Standard Mean Difference (SMD), and the results were: aerobic exercise [SMD = -0.53, 95% CI (-0.77, -0.30), I2 = 80%, P < .001], traditional Chinese exercises [SMD = -0.42, 95% CI (-0.74, -0.10), I2 = 90%, P = .01], meditation [SMD = -0.51, 95% CI (-0.90, -0.12), I2 = 79%, P = .01]. There was greater heterogeneity among the included studies: aerobic exercise (I2 = 80%, P < .001), traditional Chinese medicine methods (I2 = 90%, P < .001), and meditation (I2 = 79%, P < .001).

CONCLUSIONS

This study revealed that the depression symptoms of college students can be effectively improved by aerobic exercise, traditional Chinese exercises, and meditation. Aerobic exercise would have a better effect on anxiety and stress while traditional Chinese exercise would have a better effect on stress. Further research (such as high-quality randomized controlled trials and long-term follow-up) is required to evaluate the effects of aerobic exercise, traditional Chinese exercise, and meditation on the depressive symptoms of college students to further apply complementary and alternative therapies.

ETHICS AND DISSEMINATION

The results of the effects of aerobic exercise, traditional Chinese exercises, and meditation on depressive symptoms for a college student will be reported in a peer-reviewed publication. Hopefully, our findings from this meta-analysis can provide the most up-to-date evidence for the contribution to preventing the occurrence of depressive symptoms in college students.

Brief EcoMeditation Associated With Psychological Improvements: A Preliminary Study

BACKGROUND

A growing body of clinical research attests to the psychological and physiological benefits of meditation. EcoMeditation is a non-pharmacological therapeutic approach used to promote health and well-being, comprising four evidence-based techniques: The Quick Coherence Technique for regulating heart rate variability (HRV), Emotional Freedom Techniques (EFT), mindfulness, and neurofeedback.

OBJECTIVES

This study investigated changes in psychological symptoms of anxiety, depression, posttraumatic stress disorder (PTSD), pain, and happiness following a one-day EcoMeditation training workshop delivered in a large-group format and at 3-months post-intervention.

METHODS

A convenience sample of 208 participants (137 women, 71 men) aged between 21 and 87 years (M = 55.4 years; SD = 12.8 years) attended a one-day EcoMeditation training workshop. Participants completed a pen-and-paper survey pre-workshop and post-workshop, and an online survey three months following the EcoMeditation intervention.

RESULTS

Post-workshop results revealed significant reductions in anxiety (-23.4%, p < .001), depression (-15.8%, p = .011), PTSD (-11.8%, p < .001), and pain (-18.5%, p < .001), while happiness scores increased significantly (+8.9%, p < .001). At 3-month follow-up, one-way repeated-measures ANOVA (N = 65) found significant decreases in anxiety between pre-test and post-test, and pain between pre-intervention and 3-month follow-up. Differences in depression and PTSD scores were not significant over time. Happiness scores significantly increased from pre-test to 3-month follow-up. However, post-hoc analyses suggested that the final sample size was inadequate to detect significant differences between time points.

CONCLUSION

Findings provide preliminary support for EcoMeditation as a brief group-based stress reduction intervention with benefits for improved psychological functioning.

Brief Mindfulness Meditation Induces Gray Matter Changes in a Brain Hub

Previous studies suggest that the practice of long-term (months to years) mindfulness meditation induces structural plasticity in gray matter. However, it remains unknown whether short-term (<30 days) mindfulness meditation in novices could induce similar structural changes. Our previous randomized controlled trials (RCTs) identified white matter changes surrounding the anterior cingulate cortex (ACC) and the posterior cingulate cortex (PCC) within 2 to 4 weeks, following 5-10 h of mindfulness training. Furthermore, these changes were correlated with emotional states in healthy adults. The PCC is a key hub in the functional anatomy implicated in meditation and other perspectival processes. In this longitudinal study using a randomized design, we therefore examined the effect of a 10 h of mindfulness training, the Integrative Body-Mind Training (IBMT) on gray matter volume of the PCC compared to an active control-relaxation training (RT). We found that brief IBMT increased ventral PCC volume and that baseline temperamental trait-an index of individual differences was associated with a reduction in training-induced gray matter increases. Our findings indicate that brief mindfulness meditation induces gray matter plasticity, suggesting that structural changes in ventral PCC-a key hub associated with self-awareness, emotion, cognition, and aging-may have important implications for protecting against mood-related disorders and aging-related cognitive declines.

Relationship Between Trait Mindfulness and Sleep Quality in College Students: A Conditional Process Model

Sleep quality can affect the physical and mental health, as well as the personal development of college students. Mindfulness practices are known to ameliorate sleep disorder and improve sleep quality. Trait mindfulness, an innate capacity often enhanced by mindfulness training, has been shown to relate to better sleep quality and different aspects of psychological well-being. However, how individual difference factors such as trait mindfulness relate to sleep quality remains largely unclear, which limits the optimization and further application of mindfulness-based intervention schemes targeting the improvement of sleep quality. In this study, we aimed to investigate how negative emotions and neuroticism may influence the relationship between trait mindfulness and sleep quality. A conditional process model was built to examine these relationships in 1,423 Chinese young adults. Specifically, the conditional process model was constructed with trait mindfulness as the independent variable, sleep quality as the dependent variable, negative emotions as the mediating variable, and neuroticism as the moderating variable. Our results showed that negative emotions mediated the link between mindfulness and sleep quality and that neuroticism had a moderating effect on the relationship between mindfulness and sleep quality. Together, these findings suggested a potential mechanism of how trait mindfulness influences sleep quality, provided a therapeutic target for which mindfulness-based interventions may act upon to improve sleep quality, and offered a basis for prediction of different intervention effects among individuals.

Comparative Study of the Impact of Active Meditation Protocol and Silence Meditation on Heart Rate Variability and Mood in Women

Aim

The aim of this study was to understand the impact of an active meditation protocol on heart rate variability (HRV) and mood in women as compared to breath-focused silence meditation.

Materials and Methods

Women experienced two different practices of 20 min each: (a) control group: silence meditation focusing on breath and (b) experiment group: active meditation that included four activities, each lasting for 5 minutes - (1) simple humming, (2) coherent heart-focused breathing with 5s of inhalation and 5s of exhalation, (3) coherent heart-focused breathing while invoking positive emotions, and (4) guided imagery about a preidentified goal. The silence meditation encouraged women to only focus on the breath. The Positive and Negative Affect Scale measured mood before/after the practice (n = 24), and emWavePro device measured HRV parameters for 5 min before/after the practices (n = 18). Statistical data analysis was done using a paired t-test.

Results

HRV (specifically, parasympathetic nervous system [PNS]) parameters showed a statistically significant improvement in the experiment group as compared to the control group. There was a statistically significant reduction in negative affect after both the practices, and the increase in positive affect was observed only for the experiment group.

Conclusions

The active meditation provides a significant enhancement in mood and HRV parameters related to PNS as compared to silence meditation where the changes in HRV were not consistent and the positive mood did not increase significantly. Future research in this area could explore the impact of such practice for a longer duration and understand the impact of each component of the meditative practices.

Promoting Psychological Well-Being Through an Evidence-Based Mindfulness Training Program

Psychological well-being is a core feature of mental health, and may be defined as including hedonic (enjoyment, pleasure) and eudaimonic (meaning, fulfillment) happiness, as well as resilience (coping, emotion regulation, healthy problem solving). To promote psychological well-being, it is helpful to understand the underlying mechanisms associated with this construct and then develop targeted and effective training programs. In this perspective article, we discuss key components and potential brain-body mechanisms related to psychological well-being and propose mindfulness training as a promising way to improve it. Based on a series of randomized controlled trial (RCT) studies of one form of mindfulness training in adolescents and adults, the integrative body-mind training (IBMT), we use IBMT as an exemplar to provide research evidence of the positive effects of mindfulness training on psychological well-being. We focus on one of the mechanisms by which IBMT enhances psychological well-being—the interaction between mind (mindfulness) and body (bodifulness)—which involves both the central nervous system (CNS) and the autonomic nervous system (ANS). We also highlight the role of brain self-control networks, including the anterior cingulate cortex/prefrontal cortex (ACC/PFC), in improving psychological well-being. We suggest that mindfulness training may be a promising program that promotes the synergistic engagement of mind and body to achieve the goals of enhancing psychological well-being.

Neuropsychopharmacological regulation of performance on creativity-related tasks

A number of factors affect performance on tasks associated with creativity. Two pharmacological systems in particularly been identified as important for their impact on creativity, the noradrenergic system and the dopaminergic systems. Furthermore, stress is also established as an important factor impacting performance, most likely mediated by its effects on these neurotransmitter systems. Herein, we review the current literature on the relationships between stress, the noradrenergic system, the dopaminergic system, and other pharmacological factors and their effects on performance on tasks associated with creativity.

Resilience Against Traumatic Stress: Current Developments and Future Directions

Given the high prevalence of stress-related mental disorders, their impact on person, family, and society and the paucity of treatment options for most of these disorders, there is currently a pressing need for innovative approaches to deal with these issues and enhance well-being. One approach which has received increasing attention over the last decade is to shift our scientific and clinical focus from risk factors for psychopathology to factors promoting resilience and mental well-being. In order to summarize and evaluate the current state of scientific affairs on the biological basis of resilience, we provide an overview of the literature on animal and human studies of resilience. Because resilience can only truly be operationalized through longitudinal data collection and analyses, we focus primarily on longitudinal studies. This review shows that the concept of resilience is currently being operationalized, measured and even defined in widely variable manners, both within animal and human studies. We further provide an overview of existing and new strategies that could help promote resilience and which are proposed to be implemented more often in clinical situations. Finally, we summarize the challenges the field is facing and provide recommendations for future research.

Does Religion Hinder Creativity? A National Level Study on the Roles of Religiosity and Different Denominations

Creativity plays an irreplaceable role in economic and technological development. It seems that religion has a negative association with creativity. If it is true, how can we interpret the rapid development of human society with religious believers comprising 81% of global population? Based on the datasets of the World Values Survey and the Global Creativity Index, this study examined the effects of different religions/denominations on national creativity, and the moderation effect of gross domestic product per capita (GDPpc) in 87 countries. The results showed that: (1) religiosity was negatively associated with creativity at national level; (2) Proportions of Protestant and Catholic adherents in a country were both positively associated with national creativity, while proportion of Islam adherents was negatively associated with national creativity; (3) GDPpc moderated the relationships of creativity with overall religiosity, proportion of Protestant adherents, and proportion of Catholic adherents. In countries with high GDPpc, national religiosity and proportion of Islam could negatively predict national creativity, and proportion of Protestants could positively predict national creativity; in countries with low GDPpc, these relationships became insignificant. These findings suggest that national religiosity hinders creativity to a certain extent. However, some denominations (i.e., Protestant and Catholic) may exert positive influences on creativity due to their religious traditions and values. The religion-creativity relationship at national level only emerges in affluent countries.

Psychedelics, Meditation, and Self-Consciousness

In recent years, the scientific study of meditation and psychedelic drugs has seen remarkable developments. The increased focus on meditation in cognitive neuroscience has led to a cross-cultural classification of standard meditation styles validated by functional and structural neuroanatomical data. Meanwhile, the renaissance of psychedelic research has shed light on the neurophysiology of altered states of consciousness induced by classical psychedelics, such as psilocybin and LSD, whose effects are mainly mediated by agonism of serotonin receptors. Few attempts have been made at bridging these two domains of inquiry, despite intriguing evidence of overlap between the phenomenology and neurophysiology of meditation practice and psychedelic states. In particular, many contemplative traditions explicitly aim at dissolving the sense of self by eliciting altered states of consciousness through meditation, while classical psychedelics are known to produce significant disruptions of self-consciousness, a phenomenon known as drug-induced ego dissolution. In this article, we discuss available evidence regarding convergences and differences between phenomenological and neurophysiological data on meditation practice and psychedelic drug-induced states, with a particular emphasis on alterations of self-experience. While both meditation and psychedelics may disrupt self-consciousness and underlying neural processes, we emphasize that neither meditation nor psychedelic states can be conceived as simple, uniform categories. Moreover, we suggest that there are important phenomenological differences even between conscious states described as experiences of self-loss. As a result, we propose that self-consciousness may be best construed as a multidimensional construct, and that "self-loss," far from being an unequivocal phenomenon, can take several forms. Indeed, various aspects of self-consciousness, including narrative aspects linked to autobiographical memory, self-related thoughts and mental time travel, and embodied aspects rooted in multisensory processes, may be differently affected by psychedelics and meditation practices. Finally, we consider long-term outcomes of experiences of self-loss induced by meditation and psychedelics on individual traits and prosocial behavior. We call for caution regarding the problematic conflation of temporary states of self-loss with "selflessness" as a behavioral or social trait, although there is preliminary evidence that correlations between short-term experiences of self-loss and long-term trait alterations may exist.

Brief Mindfulness Meditation Improves Attention in Novices: Evidence From ERPs and Moderation by Neuroticism

Past research has found that mindfulness meditation training improves executive attention. Event-related potentials (ERPs) have indicated that this effect could be driven by more efficient allocation of resources on demanding attentional tasks, such as the Flanker Task and the Attention Network Test (ANT). However, it is not clear whether these changes depend on long-term practice. In two studies, we sought to investigate the effects of a brief, 10-min meditation session on attention in novice meditators, compared to a control activity. We also tested moderation by individual differences in neuroticism and the possible underlying neural mechanisms driving these effects, using ERPs. In Study 1, participants randomly assigned to listen to a 10-min meditation tape had better accuracy on incongruent trials on a Flanker task, with no detriment in reaction times (RTs), indicating better allocation of resources. In Study 2, those assigned to listen to a meditation tape performed an ANT more quickly than control participants, with no detriment in performance. Neuroticism moderated both of these effects, and ERPs showed that those individuals lower in neuroticism who meditated for 10 min exhibited a larger N2 to incongruent trials compared to those who listened to a control tape; whereas those individuals higher in neuroticism did not. Together, our results support the hypothesis that even brief meditation improves allocation of attentional resources in some novices.

Examining Brain Structures Associated With Emotional Intelligence and the Mediated Effect on Trait Creativity in Young Adults

Little is known about the association between emotional intelligence (EI) and trait creativity (TC), and the brain structural bases which involves. This study investigated the neuroanatomical basis of the association between EI and TC which measured by the Schutte self-report EI scale and the Williams creativity aptitude test. First, the voxel-based morphometry (VBM) analysis was used to explore the brain structures which is closely related to EI in a large young sample (n = 213). The results showed that EI was positively correlated with the regional gray matter volume (rGMV) in the right orbitofrontal cortex (OFC), which is regarded as a key region of emotional processing. More importantly, further mediation analysis revealed that rGMV in the right OFC partially mediated the association between EI and TC, which showed the OFC volume could account for the relationship between EI and TC. These findings confirmed the close relationship between EI and TC, and highlighted that the brain volumetric variation in the OFC associated with the top-down processing of emotion regulation, which may play a critical role in the promotion of TC. Together, these findings contributed to sharpening the understanding of the complex relationship between EI and TC from the perspective of brain structural basis.

The Interrelated Physiological and Psychological Effects of EcoMeditation

This study investigated changes in psychological and physiological markers during a weekend meditation workshop (N = 34). Psychological symptoms of anxiety, depression, posttraumatic stress disorder (PTSD) and happiness were assessed. Physiological markers included cortisol, salivary immunoglobulin A (SigA), heart rate variability (HRV), blood pressure (BP), and resting heart rate (RHR). On posttest, significant reductions were found in cortisol (-29%, P < .0001), RHR (-5%, P = .0281), and pain (-43%, P = .0022). Happiness increased significantly (+11%, P = .0159) while the increase in SigA was nonsignificant (+27%, P = .6964). Anxiety, depression, and PTSD all declined (-26%, P = .0159; -32%, P = .0197; -18%, P = .1533), though changes in PTSD did not reach statistical significance. No changes were found in BP, HRV, and heart coherence. Participants were assessed for psychological symptoms at 3-month follow-up, but the results were nonsignificant due to inadequate sample size (n = 17). EcoMeditation shows promise as a stress-reduction method.

[Mindful neuropsychology: Mindfulness-based cognitive remediation]

OBJECTIVES

Mindfulness based interventions (MBI) have recently gained much interest in western medicine. MBSR paradigm is based on teaching participants to pay complete attention to the present experience and act nonjudgmentally towards stressful events. During this mental practice the meditator focuses his or her attention on the sensations of the body. While the distractions (mental images, thoughts, emotional or somatic states) arise the participant is taught to acknowledge discursive thoughts and cultivate the state of awareness without immediate reaction. The effectiveness of these programs is well documented in the field of emotional response regulation in depression (relapse prevention), anxiety disorders, obsessive-compulsive disorder or eating disorders. Furthermore, converging lines of evidence support the hypothesis that mindfulness practice improves cognition, especially the ability to sustain attention and think in a more flexible manner. Nevertheless, formal rehabilitation programs targeting cognitive disturbances resulting from psychiatric (depression, disorder bipolar, schizophrenia) or neurologic conditions (brain injury, dementia) seldom rely on MBI principles. This review of literature aims at discussing possible links between MBI and clinical neuropsychology.

METHODS

We conducted a review of literature using electronic databases up to December 2016, screening studies with variants of the keywords ("Mindfulness", "MBI", "MBSR", "Meditation") OR/AND ("Cognition", "Attention", "Executive function", "Memory", "Learning") RESULTS: In the first part, we describe key concepts of the neuropsychology of attention in the light of Posner's model of attention control. We also underline the potential scope of different therapeutic contexts where disturbances of attention may be clinically relevant. Second, we review the efficacy of MBI in the field of cognition (thinking disturbances, attention biases, memory and executive processes impairment or low metacognitive abilities), mood (emotional dysregulation, anxiety, depression, mood shifts) and somatic preoccupations (stress induced immune dysregulation, chronic pain, body representation, eating disorders, sleep quality, fatigue). In psychiatry, these three components closely coexist and interact which explains the complexity of patient assessment and care. Numerous studies show that meditation inspired interventions offer a promising solution in the prevention and rehabilitation of cognitive impairment. In the last part, we discuss the benefits and risks of integrating meditation practice into broader programs of cognitive remediation and therapeutic education in patients suffering from cognitive disorders. We propose a number of possible guidelines for developing mindfulness inspired cognitive remediation tools. Along with Jon Kabatt Zinn (Kabatt-Zinn & Maskens, 2012), we suggest that the construction of neuropsychological tools relies on seven attitudinal foundations of mindfulness practice.

CONCLUSIONS

This paper highlights the importance of referring to holistic approaches such as MBI when dealing with patients with neuropsychological impairment, especially in the field of psychiatry. We advocate introducing mindfulness principles in order to help patients stabilize their attention and improve cognitive flexibility. We believe this transition in neuropsychological care may offer an interesting paradigm shift promoting a more efficient approach towards cognition and its links to emotion, body, and environment.

Brief Mental Training Reorganizes Large-Scale Brain Networks

Emerging evidences have shown that one form of mental training—mindfulness meditation, can improve attention, emotion regulation and cognitive performance through changing brain activity and structural connectivity. However, whether and how the short-term mindfulness meditation alters large-scale brain networks are not well understood. Here, we applied a novel data-driven technique, the multivariate pattern analysis (MVPA) to resting-state fMRI (rsfMRI) data to identify changes in brain activity patterns and assess the neural mechanisms induced by a brief mindfulness training—integrative body–mind training (IBMT), which was previously reported in our series of randomized studies. Whole brain rsfMRI was performed on an undergraduate group who received 2 weeks of IBMT with 30 min per session (5 h training in total). Classifiers were trained on measures of functional connectivity in this fMRI data, and they were able to reliably differentiate (with 72% accuracy) patterns of connectivity from before vs. after the IBMT training. After training, an increase in positive functional connections (60 connections) were detected, primarily involving bilateral superior/middle occipital gyrus, bilateral frontale operculum, bilateral superior temporal gyrus, right superior temporal pole, bilateral insula, caudate and cerebellum. These results suggest that brief mental training alters the functional connectivity of large-scale brain networks at rest that may involve a portion of the neural circuitry supporting attention, cognitive and affective processing, awareness and sensory integration and reward processing.

The impact of resilience on psychological outcomes in women with threatened premature labor and spouses: a cross-sectional study in Southwest China

Background

Threatened premature labor (TPL) is a severe obstetric complication which affects the mental and physical health of both the mother and fetus. Family resilience may have protective role against psychological distress in women experiencing these pregnancy complications. There may be resilience related risk factors in TPL women, and interplays may exist among psychological variables and within couples. This study aims to examine psychological outcomes influenced by different levels of resilience, and explore psychological interactions in TPL women, spouses, and between women and spouses.

Methods

Six validated questionnaires were used to measure the psychological outcomes (Connor-Davidson resilience scale CD-RISC, Edinburgh postnatal depression scale EPDS, positive and negative affect scale PANAS, pregnancy pressure scale PPS, simplified coping style questionnaire SCSQ, social support rating scale SSRS) in 126 TPL women hospitalized in three tertiary hospitals and 104 spouses in Southwest China.

Results

Low resilient women had significantly more complicated placenta praevia, longer pediatric observation, more pressure than high resilient women. They also had significantly less active coping and positive affect, more negative affect and depression compared to high resilient women and their spouses. Although the socio-demographic characteristics of both TPL women and spouses and psychometric parameters of spouses had no significant differences, the prevalence rates of depression in spouses were notable. Compared with spouses, TPL women had a more complex interaction among these psychometric factors, with women’s resilience negatively associated with their partners’ negative affect, and their pressure positively correlated with pressure and negative affect of spouses.

Conclusions

Pregnancy complicated with placenta praevia and pediatric observation may be risk factors for resilience of women with TPL. Maternal resilience has an important impact on the psychological outcomes in TPL women. A screening for resilience, depression and other psychological outcomes in couples with TPL and early psychological intervention of low resilient couples may be appropriate to promote resilience and well-being of these families.

A translational neuroscience perspective on mindfulness meditation as a prevention strategy

Mindfulness meditation research mainly focuses on psychological outcomes such as behavioral, cognitive, and emotional functioning. However, the neuroscience literature on mindfulness meditation has grown in recent years. This paper provides an overview of relevant neuroscience and psychological research on the effects of mindfulness meditation. We propose a translational prevention framework of mindfulness and its effects. Drawing upon the principles of prevention science, this framework integrates neuroscience and prevention research and postulates underlying brain regulatory mechanisms that explain the impact of mindfulness on psychological outcomes via self-regulation mechanisms linked to underlying brain systems. We conclude by discussing potential clinical and practice implications of this model and directions for future research.

The Associations of Naturalistic Classic Psychedelic Use, Mystical Experience, and Creative Problem Solving

Developing methods for improving creativity is of broad interest. Classic psychedelics may enhance creativity; however, the underlying mechanisms of action are unknown. This study was designed to assess whether a relationship exists between naturalistic classic psychedelic use and heightened creative problem-solving ability and if so, whether this is mediated by lifetime mystical experience. Participants (N = 68) completed a survey battery assessing lifetime mystical experience and circumstances surrounding the most memorable experience. They were then administered a functional fixedness task in which faster completion times indicate greater creative problem-solving ability. Participants reporting classic psychedelic use concurrent with mystical experience (n = 11) exhibited significantly faster times on the functional fixedness task (Cohen's d = -.87; large effect) and significantly greater lifetime mystical experience (Cohen's d = .93; large effect) than participants not reporting classic psychedelic use concurrent with mystical experience. However, lifetime mystical experience was unrelated to completion times on the functional fixedness task (standardized β = -.06), and was therefore not a significant mediator. Classic psychedelic use may increase creativity independent of its effects on mystical experience. Maximizing the likelihood of mystical experience may need not be a goal of psychedelic interventions designed to boost creativity.

Cognitive Effects of Mindfulness Training: Results of a Pilot Study Based on a Theory Driven Approach

The present paper reports a pilot study which tested cognitive effects of mindfulness practice in a theory-driven approach. Thirty-four fifth graders received either a mindfulness training which was based on the mindfulness-based stress reduction approach (experimental group), a concentration training (active control group), or no treatment (passive control group). Based on the operational definition of mindfulness by Bishop et al. (2004), effects on sustained attention, cognitive flexibility, cognitive inhibition, and data-driven as opposed to schema-based information processing were predicted. These abilities were assessed in a pre-post design by means of a vigilance test, a reversible figures test, the Wisconsin Card Sorting Test, a Stroop test, a visual search task, and a recognition task of prototypical faces. Results suggest that the mindfulness training specifically improved cognitive inhibition and data-driven information processing.

Mindfulness meditation improves emotion regulation and reduces drug abuse

BACKGROUND

The core clinical symptoms of addiction include an enhanced incentive for drug taking (craving), impaired self-control (impulsivity and compulsivity), emotional dysregulation (negative mood) and increased stress reactivity. Symptoms related to impaired self-control involve reduced activity in anterior cingulate cortex (ACC), adjacent prefrontal cortex (mPFC) and other brain areas. Behavioral training such as mindfulness meditation can increase the function of control networks including those leading to improved emotion regulation and thus may be a promising approach for the treatment of addiction.

METHODS

In a series of randomized controlled trials (RCTs), we tested whether increased ACC/mPFC activity is related to better self-control abilities in executive functions, emotion regulation and stress response in healthy and addicted populations. After a brief mindfulness training (Integrative Body-Mind Training, IBMT), we used the Positive and Negative Affect Schedule (PANAS) and Profile of Mood States (POMS) to measure emotion regulation, salivary cortisol for the stress response and fMRI for brain functional and DTI structural changes. Relaxation training was used to serve as an active control.

RESULTS

In both smokers and nonsmokers, improved self-control abilities in emotion regulation and stress reduction were found after training and these changes were related to increased ACC/mPFC activity following training. Compared with nonsmokers, smokers showed reduced ACC/mPFC activity in the self-control network before training, and these deficits were ameliorated after training.

CONCLUSIONS

These results indicate that promoting emotion regulation and improving ACC/mPFC brain activity can help for addiction prevention and treatment.

The Creative Process: Effort and Effortless Cognition

Education at its best allows students to experience the fruitfulness and joy of the creative process. One complexity of applying research findings to education is that creative work unfolds in phases and the various phases engage distinctively different cognitive processes. Since Wallas first described four phases, psychologists have elaborated on them and pointed to additional phases and subphases. Some involve effortful conscious processes; others entail implicit cognition and/or effortless attention. The field has benefitted from research in related areas as well as from direct studies of conditions that enhance various phases of creative performance. This article reviews current knowledge on the phases and incorporates findings from related areas. The challenge for educators is to structure student work in ways which support the different phases—both deliberate phases such as preparation and evaluation and those which appear to emerge spontaneously such as insight and flow. The findings underscore of the value of specific classroom activities, activities which scaffold and/or invite the different phases of creative work. The cognitive processes engaged by the creative process also benefit from other activities which enhance executive function, elevate mood, and allow opportunities for flow.

Embodied cognitive flexibility and neuroplasticity following Quadrato Motor Training

Quadrato Motor Training (QMT) is a whole-body movement contemplative practice aimed at increasing health and well-being. Previous research studying the effect of one QMT session suggested that one of its means for promoting health is by enhancing cognitive flexibility, an important dimension of creativity. Yet, little is known about the effect of a longer QMT practice on creativity, or the relative contribution of the cognitive and motor aspects of the training. Here, we continue this line of research in two inter-related studies, examining the effects of prolonged QMT. In the first, we investigated the effect of 4-weeks of daily QMT on creativity using the Alternate Uses (AUs) Task. In order to determine whether changes in creativity were driven by the cognitive or the motor aspects of the training, we used two control groups: Verbal Training (VT, identical cognitive training with verbal response) and Simple Motor Training (SMT, similar motor training with reduced choice requirements). Twenty-seven participants were randomly assigned to one of the groups. Following training, cognitive flexibility significantly increased in the QMT group, which was not the case for either the SMT or VT groups. In contrast to one QMT session, ideational fluency was also significantly increased. In the second study, we conducted a pilot longitudinal structural magnetic resonance imaging and diffusion tensor imaging (4-weeks QMT). We report gray matter volume and fractional anisotropy changes, in several regions, including the cerebellum, previously related to interoceptive accuracy. The anatomical changes were positively correlated with cognitive flexibility scores. Albeit the small sample size and preliminary nature of the findings, these results provide support for the hypothesized creativity-motor connection. The results are compared to other contemplative studies, and discussed in light of theoretical models integrating cognitive flexibility, embodiment and the motor system.

Time course of conflict processing modulated by brief meditation training

Resolving conflict is a pivotal self-control ability for human adaptation and survival. Although some studies reported meditation may affect conflict resolution, the neural mechanisms are poorly understood. We conducted a fully randomized 5 h trial of one form of mindfulness meditation—integrative body-mind training (IBMT) in comparison to a relaxation training control. During the Stroop word-color task, IBMT group produced faster resolution of conflict, a smaller N2 and an earlier and larger P3 component of the event-related brain potentials. These results indicate that brief meditation training induces a brain state that improves the resolution of conflict.

Short-term meditation increases blood flow in anterior cingulate cortex and insula

Asymmetry in frontal electrical activity has been reported to be associated with positive mood. One form of mindfulness meditation, integrative body-mind training (IBMT) improves positive mood and neuroplasticity. The purpose of this study is to determine whether short-term IBMT improves mood and induces frontal asymmetry. This study showed that 5-days (30-min per day) IBMT significantly enhanced cerebral blood flow (CBF) in subgenual/adjacent ventral anterior cingulate cortex (ACC), medial prefrontal cortex and insula. The results showed that both IBMT and relaxation training increased left laterality of CBF, but only IBMT improved CBF in left ACC and insula, critical brain areas in self-regulation.
