The Neuropsychological Connection Between Creativity and Meditation

Hidden Brain States Reveal the Temporal Dynamics of Neural Oscillations During Metaphor Generation and Their Role in Verbal Creativity

We investigated the oscillatory brain processes while people generated metaphors for science concepts. Applying a hidden Markov model, we extracted brain states, representing temporally disentangled oscillatory processes, from EEG data. By associating the trial-by-trial occupancy of brain states with the creative quality, novelty, and aptness of the generated metaphors, we identified oscillatory processes that played a role in creative ideation in a data-driven manner. Metaphor novelty was positively associated with occupancy in a state featuring widespread alpha-band synchronization during the early trial stage and occupancy in a state featuring alpha-band desynchronization during the later trial stage. In addition, metaphor novelty was negatively associated with gamma-band power. Our results not only extend previous literature on the role of oscillatory processes in creative ideation but also highlight the importance of temporal dynamics in understanding the brain mechanisms during sustained cognitive task performance.

Differential effects of digital mindfulness-based interventions on creative potential and responsibility among middle school students

BACKGROUND

Creativity and responsibility are enhanced by meditation among adults, but such effects have not been studied in adolescents. Moreover, the determinants of the ethical effect (such as responsibility) of meditation are unclear.

AIMS

To address this gap by investigating the impact of digital in-class meditation programmes in middle school, focusing on intentions (self-centred vs. responsibility-centred), on adolescents' creative potential and sense of responsibility. These intentions are operationalized by different purpose-based meditations.

METHODS

We conducted a cluster randomized controlled trial involving 107 year 7 adolescents from six classes, assigning them to two experimental groups and an active control group. Pre- and post-intervention assessments were conducted over an 11-week period, including a creativity (EPoC) test comprising four exercises (graphic and verbal, divergent and convergent thinking), a responsibility and a mindfulness scale.

RESULTS

Our findings revealed no discernible effects on divergent thinking or self-reported mindfulness. However, we observed significant differences in graphic and verbal convergent creative thinking, as well as impacting responsibility scores, between a responsibility-centred meditation group and a self-centred meditation group. Moreover, distinctions were noted between control and self-centred meditation groups and between some classes. Effect sizes indicated that the interventions had a moderate but significant impact on the variables measured.

CONCLUSION

Our study reveals the effectiveness of digital meditation interventions in enhancing convergent creative thinking and responsibility among middle-school students. Notably, it shed new light on the importance of meditation intentions, which may be as significant as the form of meditation itself.

Functional reorganization of the brain in distinct frequency bands during eyes-open meditation

Meditation is a self-regulatory process practiced primarily to reduce stress, manage emotions and mental health. The objective of this work is to study the information exchange between electrodes within and across the hemispheres during meditation using functional connectivity (FC) measures. We investigate the changes in the coherence between EEG electrode pairs during the meditation with open eyes practiced by long-term Brahmakumaris Rajyoga meditators and during listening to music by controls as the comparable task. FC derived from coherency, pairwise phase consistency (PPC) is used to study the changes in intra and interhemispheric coherence. Integrating connectivity (IC) derived from node degree strength has also been analyzed. Meditators show increased PPC in higher theta and alpha bands both within and across hemispheres. However, the control subjects with no knowledge of meditation show no change in theta band during the music session. Further, during baseline conditions, higher interhemispheric anterior to posterior IC is found in meditators in higher beta and slow gamma bands than controls. Distinct patterns of changes are observed with the PPC and IC measures in different frequency bands during meditation in the meditators and music-listening session in the control subjects indicating varied information processing between the right and left hemispheres. Increased IC is found between the frontal electrodes implying increased self-awareness in meditators. The PPC between the occipital electrodes in meditators is less than the controls in baseline condition indicating a possible modified visual information processing in Rajyoga meditators due to the long-term practice of meditation with open eyes. Overall, the changes in PPC and associated IC indicate increased functional integration during meditation supporting the hypothesis of communication through coherence and cortical integration theory during the non-ordinary state of consciousness induced by meditation.

Restructuring insight: An integrative review of insight in problem-solving, meditation, psychotherapy, delusions and psychedelics

Occasionally, a solution or idea arrives as a sudden understanding - an insight. Insight has been considered an "extra" ingredient of creative thinking and problem-solving. Here we propose that insight is central in seemingly distinct areas of research. Drawing on literature from a variety of fields, we show that besides being commonly studied in problem-solving literature, insight is also a core component in psychotherapy and meditation, a key process underlying the emergence of delusions in schizophrenia, and a factor in the therapeutic effects of psychedelics. In each case, we discuss the event of insight and its prerequisites and consequences. We review evidence for the commonalities and differences between the fields and discuss their relevance for capturing the essence of the insight phenomenon. The goal of this integrative review is to bridge the gap between the different views and inspire interdisciplinary research efforts for understanding this central process of human cognition.

Beyond alpha-band: The neural correlate of creative thinking

The compound nature of creativity entails the interplay of multiple cognitive processes, making it difficult to attribute creativity to a single neural signature. Divergent thinking paradigms, widely adopted to investigate creative production, have highlighted the key role of specific mental operations subserving creativity, such as inhibition of external stimuli, loose semantic associations, and mental imagery. Neurophysiological studies have typically shown a high alpha rhythm synchronization when individuals are engaged in creative ideation. Also, oculomotor activity and pupil diameter have been proposed as useful indicators of mental operations involved in such a thinking process. The goal of this study was to investigate whether beyond alpha-band activity other higher frequency bands, such as beta and gamma, may subserve divergent and convergent thinking and whether those could be associated with a different gaze bias and pupil response during ideas generation. Implementing a within-subjects design we collected behavioral measures, neural activity, gaze patterns, and pupil dilation while participants performed a revised version of the Alternative Uses Task, in which divergent thinking is contrasted to convergent thinking. As expected, participants took longer to generate creative ideas as compared to common ones. Interestingly, during divergent thinking participants displayed alpha synchronization along with beta and gamma desynchronization, more pronounced leftward gaze shift, and greater pupil dilation. During convergent thinking, an opposite pattern was observed: desynchronization in alpha and an increase in beta and gamma rhythm, along with a reduction of leftward gaze shift and greater pupil constriction. The present study uncovered specific neural dynamics and physiological patterns during idea generation, providing novel insight into the complex physiological signature of creative production.

Power Spectrum and Connectivity Analysis in EEG Recording during Attention and Creativity Performance in Children

The present research aims at examining the power spectrum and exploring functional brain connectivity/disconnectivity during concentration performance, as measured by the d2 test of attention and creativity as measured by the CREA test in typically developing children. To this end, we examined brain connectivity by using phase synchrony (i.e., phase locking index (PLI) over the EEG signals acquired by the Emotiv EPOC neuroheadset in 15 children aged 9- to 12-years. Besides, as a complement, a power spectrum analysis of the acquired signals was performed. Our results indicated that, during d2 Test performance there was an increase in global gamma phase synchronization and there was a global alpha and theta band desynchronization. Conversely, during CREA task, power spectrum analysis showed a significant increase in the delta, beta, theta, and gamma bands. Connectivity analysis revealed marked synchronization in theta, alpha, and gamma. These findings are consistent with other neuroscience research indicating that multiple brain mechanisms are indeed involved in creativity. In addition, these results have important implications for the assessment of attention functions and creativity in clinical and research settings, as well as for neurofeedback interventions in children with typical and atypical development.

HeartMath as an Integrative, Personal, Social, and Global Healthcare System

COVID-19 is a recent major event, adding to planet Earth’s contexts of chaos, crime, injustice, illness, and violence. The HeartMath system has produced research evidence for scientific interventions that alter contexts characterized by chaos and stress, promoting health, coherence, and interconnectedness. This study provides an updated overview of HeartMath as an interdisciplinary, scientific, coherent, integral heart-based healthcare system, operated locally through various initiatives and globally through the Global Coherence Initiative. The HeartMath approach integrates ancient and contemporary, indigenous and mainstream, popular and folk, Eastern, Western, and African forms of healing. The HeartMath interdisciplinary, personal, social, and global vision and mission have considerable theoretical and practical potential for promoting planetary health, education, and development.

Mindfulness-Training in Preadolescents in School: The Role of Emotionality, EEG in Theta/Beta Bands, Creativity and Attention

Mindfulness meditation is a means of increasing awareness of the present moment. Mindfulness Mediation Interventions (MMI) positively impact psychological functioning, yet the neurocognitive mechanisms that mediate these effects have been less well-defined. Here, the primary aim was to evaluate whether the effects of a 10-week MMI were mediated by changes in attention and creativity performance, as well as resting-state theta/beta (TB) ratio and alpha power. We also sought to determine whether any of these measures at baseline were predictive of mindfulness success, as rated by the 7-11-year-old participants and their teachers. Reductions in depression from pre-to-post were mediated by reductions in TB ratio and increases in alpha power; however, they were not mediated by attention/creativity changes. Higher baseline attention and creativity scores predicted enhanced mindfulness success post-intervention but notably, follow-up analyses revealed that those scoring lower on these measures were more likely to have reduced depression from pre-to-post.

Experience of Managing Countertransference Through Self-Guided Imagery in Meditation Among Healthcare Professionals

INTRODUCTION

As a part of the therapeutic relationship, a significant, well-established predictor of outcomes in psychiatric healthcare, healthcare professionals' emotional reactions to patients may affect treatment outcomes.

AIM

The aim of our study was to explore and describe healthcare professionals' experiences with managing countertransference using skills from a training program on self-guided imagery in meditation (SIM).

METHOD

Following an exploratory descriptive design, we conducted qualitative interviews with 10 healthcare professionals who care for patients with mental illness and subjected the collected data to thematic content analysis.

RESULTS

Participants reported that SIM had helped them to manage countertransference and had prompted changes that we categorized into three themes: managing personal vulnerability, setting clearer boundaries, and practicing self-care.

CONCLUSION

The results suggest that by cultivating wellbeing and dealing with unresolved inner conflicts, SIM can help healthcare professionals to manage countertransference.

Influence of dental magnets on human brain activity: A quantitative EEG analysis

PURPOSE

The magnetic field is known to attenuate mental depression, but it is not clear on the effect of dental magnets on human brain activity. Therefore, this study was to determine the influence of magnetic field from intraoral magnets on the human brain activity by analyzing the changes in alpha waves.

MATERIALS AND METHODS

Twenty complete denture male patients aged between 50 and 60 years were included after their consent. The neodymium-iron-boron sintered magnet was incorporated into the existing mandibular denture bilaterally in canine region. The participants were subjected to electroencephalogram (EEG) and the output measured alpha waves at three phases: (i) without placement of magnets (WM0), (ii) 30 days post-magnet placement in the mandibular denture (WM), and (iii) after 6 months post-removal of magnets (WM6). The data obtained was skewed (non-parametric), and hence multivariate analysis using Friedman test, and bivariate analysis using Wilcoxon signed rank test and Mann-Whitney test were done to assess the significant difference among the groups.

RESULTS

The comparison of alpha waves between different phases showed a significant difference in all the pairs (p < .05) except WM-WM6. Comparison of alpha waves between right and left hemisphere showed no statistically significant difference (p > .05).

CONCLUSION

We concluded that dental magnets had an influential effect on the alpha waves in the brain on both the left and right hemispheres. The removal of dental magnets retained the changes in brain activity even after 6 months of removal, denoting the alternative therapy to management of mental depression.

Mindfulness and creativity: Implications for thinking and learning

Mindfulness and creativity have both come to the forefront of educational interest-but a better understanding of their relationship and the implications for education is needed. This article reviews the literature on the intersection of these topics in order to understand where and how these two related but distinctive areas of research connect, and how this pertains to the complexity of education settings. Our goal is to understand findings from the literature and consider the implications for educational practice and research, with an eye to how mindfulness can be supportive to learners' creativity. This thematic review and qualitative analysis of extant literature identifies four themes that speak to the connection between mindfulness and creativity. There is solid evidence to show a generally beneficial and supportive relationship, in that practicing mindfulness can support creativity-but many factors affect this and there are a range of considerations for practice. This article reflects on the key findings of scholarly work on the mindfulness-creativity relationship with interpretative discussion and implications for educational research and practice.

Reflections on Inner and Outer Silence and Consciousness Without Contents According to the Sphere Model of Consciousness

In the current hypothesis paper, we propose that focusing attention on silence can be used as a paradigm conceptually similar to sensory deprivation, to study consciousness without content. We briefly overview recent influential models of consciousness and consider how they assess the relationship between consciousness and contents. After discussing the strengths and weaknesses of current models, we suggest an extension based on the Sphere Model of Consciousness (SMC) and introduce new definitions for identification and self-awareness as states of consciousness. We further compare Paoletti's theoretical model for the development of self with other influential models, highlighting similarities and differences. We conclude with a discussion of how attentional focus on silence can be empirically tested.

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.

Long-term meditation: the relationship between cognitive processes, thinking styles and mindfulness

The aim of this study is to examine the relationship between meditation and cognitive functions. More in depth the purpose is to demonstrate that long-term meditation practice improves attention skills and cognitive flexibility. Eighteen long-term meditation practitioners were compared to a matched control group, who never practiced meditation. Each subject was tested, using computerized software (Presentation Software 9.90), which measured: attention, visual search abilities, working memory and Stroop's interference tasks. Furthermore, we examined the relationship between long-term meditation practice, mindfulness skills and thinking styles, namely styles of processing information. The results showed significant differences between the two groups, demonstrating that long-term meditation is linked to improvements of attentional functions, working memory and cognitive flexibility.

EEG Brain Wave Activity at Rest and during Evoked Attention in Children with Attention-Deficit/Hyperactivity Disorder and Effects of Methylphenidate

OBJECTIVE

The aim of this study was to assess baseline EEG brain wave activity in children with attention-deficit/hyperactivity disorder (ADHD) and to examine the effects of evoked attention and methylphenidate on this activity.

METHOD

Children with ADHD (n = 19) were tested while they were stimulant free and during a period in which they were on stimulant (methylphenidate) medication. Control subjects (n = 18) were tested once. EEG brain wave activity was tested both at baseline and during focussed attention. Attention was evoked and EEG brain wave activity was determined by means of the BioGraph Infiniti biofeedback apparatus.

RESULTS

The main finding of this study was that control subjects and stimulant-free children with ADHD exhibited the expected reactivity in high alpha-wave activity (11-12 Hz) from baseline to focussed attention; however, methylphenidate appeared to abolish this reactivity.

CONCLUSION

Methylphenidate attenuates the normal cortical response to a cognitive challenge.

Opening the Door to Creativity: A Psychosynthesis Approach

Given the great importance of creativity in society, and in health psychology in particular, investigating how creativity can be enhanced is a valuable area of research. Interventions that enable individuals to become more creative vary in their focus from increasing divergent thinking to task reactivation during sleep. This article introduces psychosynthesis psychology as an additional theoretical and therapeutic approach for enhancing creativity through its concept that creativity originates from different levels of the unconscious. We show that the subpersonality model, one of the fundamental psychosynthesis techniques, is an effective intervention for aiding creative expression as it helps people connect to different levels of their unconscious creativity. It is assumed that through the use of this technique, clients are able to release and unblock energies that not only allow them to rebuild their personal identities but also become actively creative in their daily lives. We support this assumption with qualitative findings that include testimonies from eleven clients in The Netherlands who received psychosynthesis counseling. In addition, qualitative data of a case study demonstrates subpersonality integration and its role in helping clients to become more creative in their personal and professional lives. The present article is, to the best of our knowledge, the first to demonstrate the beneficial effects of using psychosynthesis to facilitate creativity. The framework of psychosynthesis psychology, its techniques (which include the subpersonality model), and its therapeutic approach are viable methodologies for anyone searching to unblock and activate new creative energy and achieve personal and professional growth.

Studying the default mode and its mindfulness-induced changes using EEG functional connectivity

The default mode network (DMN) has been largely studied by imaging, but not yet by neurodynamics, using electroencephalography (EEG) functional connectivity (FC). mindfulness meditation (MM), a receptive, non-elaborative training is theorized to lower DMN activity. We explored: (i) the usefulness of EEG-FC for investigating the DMN and (ii) the MM-induced EEG-FC effects. To this end, three MM groups were compared with controls, employing EEG-FC (-MPC, mean phase coherence). Our results show that: (i) DMN activity was identified as reduced overall inter-hemispheric gamma MPC during the transition from resting state to a time production task and (ii) MM-induced a state increase in alpha MPC as well as a trait decrease in EEG-FC. The MM-induced EEG-FC decrease was irrespective of expertise or band. Specifically, there was a relative reduction in right theta MPC, and left alpha and gamma MPC. The left gamma MPC was negatively correlated with MM expertise, possibly related to lower internal verbalization. The trait lower gamma MPC supports the notion of MM-induced reduction in DMN activity, related with self-reference and mind-wandering. This report emphasizes the possibility of studying the DMN using EEG-FC as well as the importance of studying meditation in relation to it.

Improving creativity performance by short-term meditation

BACKGROUND

One form of meditation intervention, the integrative body-mind training (IBMT) has been shown to improve attention, reduce stress and change self-reports of mood. In this paper we examine whether short-term IBMT can improve performance related to creativity and determine the role that mood may play in such improvement.

METHODS

Forty Chinese undergraduates were randomly assigned to short-term IBMT group or a relaxation training (RT) control group. Mood and creativity performance were assessed by the Positive and Negative Affect Schedule (PANAS) and Torrance Tests of Creative Thinking (TTCT) questionnaire respectively.

RESULTS

As predicted, the results indicated that short-term (30 min per day for 7 days) IBMT improved creativity performance on the divergent thinking task, and yielded better emotional regulation than RT. In addition, cross-lagged analysis indicated that both positive and negative affect may influence creativity in IBMT group (not RT group).

CONCLUSIONS

Our results suggested that emotion-related creativity-promoting mechanism may be attributed to short-term meditation.

Into the square and out of the box: the effects of Quadrato Motor Training on creativity and alpha coherence

The objective of the present study was to investigate the body-cognitive relationship through behavioral and electrophysiological measures in an attempt to uncover the underlying mediating neuronal mechanism for movement-induced cognitive change. To this end we examined the effects of Quadrato Motor Training (QMT), a new whole-body training paradigm on cognitive performance, including creativity and reaction time tasks, and electrophysiological change, using a within-subject pre-post design. Creativity was studied by means of the Alternate Uses Task, measuring ideational fluency and ideational flexibility. Electrophysiological effects were measured in terms of alpha power and coherence. In order to determine whether training-induced changes 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 QMT, we found enhanced inter-hemispheric and intra-hemispheric alpha coherence, and increased ideational flexibility, which was not the case for either the SMT or VT groups. These findings indicate that it is the combination of the motor and cognitive aspects embedded in the QMT which is important for increasing ideational flexibility and alpha coherence.
