Meditation,mindfulness and executive control: the importance of emotional acceptance and brain-based performance monitoring

Previous studies have documented the positive effects of mindfulness meditation on executive control. What has been lacking, however, is an understanding of the mechanism underlying this effect. Some theorists have described mindfulness as embodying two facets—present moment awareness and emotional acceptance. Here, we examine how the effect of meditation practice on executive control manifests in the brain, suggesting that emotional acceptance and performance monitoring play important roles. We investigated the effect of meditation practice on executive control and measured the neural correlates of performance monitoring, specifically, the error-related negativity (ERN), a neurophysiological response that occurs within 100 ms of error commission. Meditators and controls completed a Stroop task, during which we recorded ERN amplitudes with electroencephalography. Meditators showed greater executive control (i.e. fewer errors), a higher ERN and more emotional acceptance than controls. Finally, mediation pathway models further revealed that meditation practice relates to greater executive control and that this effect can be accounted for by heightened emotional acceptance, and to a lesser extent, increased brain-based performance monitoring.     

Meditation and psychotherapy: a rationale for the integration of dynamic psychotherapy, the relaxation response, and mindfulness meditation

A framework for the integration of meditation and psychotherapy is presented through a consideration of the psychobiological nature of meditation (the relaxation response) and discussion of a traditional meditation practice (mindfulness meditation) as an effective cognitive technique for the development of self-awareness. The mechanisms by which the emotional and cognitive changes of meditation can be of therapeutic value are explored and the synergistic advantages of the combination of psychotherapy and meditation are discussed.     

The effect of focused attention and open monitoring meditation on attention network function in healthy volunteers

Mindfulness meditation techniques are increasingly popular both as a life-style choice and therapeutic adjunct for a range of mental and physical health conditions. However, little is known about the mechanisms through which mindfulness meditation and its constituent practices might produce positive change in cognition and emotion. Our study directly compared the effects of Focused Attention (FA) and Open-Monitoring (OM) meditation on alerting, orienting and executive attention network function in healthy individuals. Participants were randomized to three intervention groups: open-focused meditation, focused attention, and relaxation control. Participants completed an emotional variant of the Attention Network Test (ANT) at baseline and post-intervention. OM and FA practice improved executive attention, with no change observed in the relaxation control group. Improvements in executive attention occurred in the absence of change in subjective/self-report mood and cognitive function. Baseline levels of dispositional/trait mindfulness were positively correlated with executive control in the ANT at baseline. Our results suggest that mindfulness meditation might usefully target deficits in executive attention that characterise mood and anxiety disorders.     

Mindful neuropsychology : repenser la réhabilitation neuropsychologique à travers la pleine conscience

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.

Mindfulness meditation regulates anterior insula activity during empathy for social pain

Mindfulness has been shown to reduce stress, promote health, and well‐being, as well as to increase compassionate behavior toward others. It reduces distress to one's own painful experiences, going along with altered neural responses, by enhancing self‐regulatory processes and decreasing emotional reactivity. In order to investigate if mindfulness similarly reduces distress and neural activations associated with empathy for others' socially painful experiences, which might in the following more strongly motivate prosocial behavior, the present study compared trait, and state effects of long‐term mindfulness meditation (LTM) practice. To do so we acquired behavioral data and neural activity measures using functional magnetic resonance imaging (fMRI) during an empathy for social pain task while manipulating the meditation state between two groups of LTM practitioners that were matched with a control group. The results show increased activations of the anterior insula (AI) and anterior cingulate cortex (ACC) as well as the medial prefrontal cortex and temporal pole when sharing others' social suffering, both in LTM practitioners and controls. However, in LTM practitioners, who practiced mindfulness meditation just prior to observing others' social pain, left AI activation was lower and the strength of AI activation following the mindfulness meditation was negatively associated with trait compassion in LTM practitioners. The findings suggest that current mindfulness meditation could provide an adaptive mechanism in coping with distress due to the empathic sharing of others' suffering, thereby possibly enabling compassionate behavior.

Brief mindfulness training for attentional problems after traumatic brain injury: A randomised control treatment trial

A mindfulness meditation technique has been shown to be effective in reducing self-reports of pain and mood disorder in chronic pain patients. Although a pilot study on traumatic brain injury patients showed improvement in self-report of cognitive impairment, a larger scale randomised control treatment trial found no differences on objective or self-report measures of cognitive function, mood or symptom reporting. Brief exposure to mindfulness meditation cannot be recommended as a treatment technique for traumatic brain injury cases.     

Neural correlates of mindfulness meditation-related anxiety relief

Anxiety is the cognitive state related to the inability to control emotional responses to perceived threats. Anxiety is inversely related to brain activity associated with the cognitive regulation of emotions. Mindfulness meditation has been found to regulate anxiety. However, the brain mechanisms involved in meditation-related anxiety relief are largely unknown. We employed pulsed arterial spin labeling MRI to compare the effects of distraction in the form of attending to the breath (ATB; before meditation training) to mindfulness meditation (after meditation training) on state anxiety across the same subjects. Fifteen healthy subjects, with no prior meditation experience, participated in 4 d of mindfulness meditation training. ATB did not reduce state anxiety, but state anxiety was significantly reduced in every session that subjects meditated. Meditation-related anxiety relief was associated with activation of the anterior cingulate cortex, ventromedial prefrontal cortex and anterior insula. Meditation-related activation in these regions exhibited a strong relationship to anxiety relief when compared to ATB. During meditation, those who exhibited greater default-related activity (i.e. posterior cingulate cortex) reported greater anxiety, possibly reflecting an inability to control self-referential thoughts. These findings provide evidence that mindfulness meditation attenuates anxiety through mechanisms involved in the regulation of self-referential thought processes.     

Impact of meditation training on the default mode network during a restful state

Mindfulness meditation has been shown to promote emotional stability. Moreover, during the processing of aversive and self-referential stimuli, mindful awareness is associated with reduced medial prefrontal cortex (MPFC) activity, a central default mode network (DMN) component. However, it remains unclear whether mindfulness practice influences functional connectivity between DMN regions and, if so, whether such impact persists beyond a state of meditation. Consequently, this study examined the effect of extensive mindfulness training on functional connectivity within the DMN during a restful state. Resting-state data were collected from 13 experienced meditators (with over 1000 h of training) and 11 beginner meditators (with no prior experience, trained for 1 week before the study) using functional magnetic resonance imaging (fMRI). Pairwise correlations and partial correlations were computed between DMN seed regions’ time courses and were compared between groups utilizing a Bayesian sampling scheme. Relative to beginners, experienced meditators had weaker functional connectivity between DMN regions involved in self-referential processing and emotional appraisal. In addition, experienced meditators had increased connectivity between certain DMN regions (e.g. dorso-medial PFC and right inferior parietal lobule), compared to beginner meditators. These findings suggest that meditation training leads to functional connectivity changes between core DMN regions possibly reflecting strengthened present-moment awareness.     

Comment mesurer la mindfulness ? Problèmes et perspectives

IntroductionThe concept of mindfulness is characterized by awareness and acceptance of experiences; flexible regulation of attention; an objective receptivity to experience and an orientation to the here-and-now. Interest in ‘mindfulness’ and ‘mindfulness meditation’ is recent and growing both at the levels of research and of clinical practice in the West as mindfulness is associated with health and well-being. It (mindfulness) is attained by the practice of certain types of meditation. One of the current key challenges is to evaluate and measure the level of mindfulness of a subject and its evolution.ObjectivesThe paper proposes a reflexion on the concept of mindfulness with a view to improving the operational evaluation of mindfulness level for clinical and non-clinical subjects.MethodsFirst, the problems with the use of existing self-report questionnaires assessing mindfulness level are discussed. Second, an analysis of the cognitive processes that come into play in mindfulness acquisition (by meditation) can highlight the significance of certain cognitive tools in a more accurate evaluation of the level of mindfulness of individuals.ConclusionSelf-regulation of attention, and orientation to lived experience could be operational candidates for assessing the level of mindfulness. The pertinence of well-known paradigms evaluating self-regulation of attention and orientation to experience are discussed.     

A systematic review of the neurophysiology of mindfulness on EEG oscillations

Mindfulness meditation has been purported to be a beneficial practice for wellbeing. It would therefore be expected that the neurophysiology of mindfulness would reflect this impact on wellbeing. However, investigations of the effects of mindfulness have generated mixed reports of increases, decreases, as well as no differences in EEG oscillations in comparison with a resting state and a variety of tasks. We have performed a systematic review of EEG studies of mindfulness meditation in order to determine any common effects and to identify factors which may impact on the effects. Databases were reviewed from 1966 to August 2015. Eligibility criteria included empirical quantitative analyses of mindfulness meditation practice and EEG measurements acquired in relation to practice. A total of 56 papers met the eligibility criteria and were included in the systematic review, consisting of a total 1715 subjects: 1358 healthy individuals and 357 individuals with psychiatric diagnoses. Studies were principally examined for power outcomes in each bandwidth, in particular the power differentials between mindfulness and a control state, as well as outcomes relating to hemispheric asymmetry and event-related potentials. The systematic review revealed that mindfulness was most commonly associated with enhanced alpha and theta power as compared to an eyes closed resting state, although such outcomes were not uniformly reported. No consistent patterns were observed with respect to beta, delta and gamma bandwidths. In summary, mindfulness is associated with increased alpha and theta power in both healthy individuals and in patient groups. This co-presence of elevated alpha and theta may signify a state of relaxed alertness which is conducive to mental health.     

Mindfulness and Awareness: Constructivist, Psychodynamic and Eastern Perspectives

In this paper I develop my contention that reality is experienced polymorphically at different levels along a concrete-abstract continuum. At the more abstract and psychic level the internal representations of primary reality are, to varying degrees, verbally labelled. However, for various reasons, this verbal symbolisation is rarely adequate or complete??even in adulthood, and hence the persistent recourse to somatisation, acting out, projection and other psychological strategies and defences. This paper also examines, using both constructivist and psychodynamic models, how verbalisation can be helpful in clinical practice with somatoform disorders as both models are concerned with the ??talking cure??. Drawing on our understanding of meditation and mindfulness, the role of our psychological defences in limiting our consciousness is examined, in contrast to the practice of non-verbal mindfulness which aims at expanding our awareness. Potential problems with meditation are discussed, as well as limitations to the ??talking cure????as verbalisation can also be used as a higher order defence. However, it is concluded that all awareness expanding practices, such as mindfulness and psychotherapy, reduce the need to resort to somatisation and other primitive awareness distorting strategies. In this paper constructivist (Kellian) and psychodynamic (both Freudian and post-Freudian) perspectives are employed to develop my contention that reality is experienced polymorphically at different levels of cognitive awareness along a concrete-abstract continuum. At a more abstract (or largely psychic) level the internal representations of primary reality become, to varying degrees, verbally labelled as we develop and mature from infancy. However, this verbal symbolisation is rarely sufficient or complete??even in adulthood, and hence the persistent need for somatisation, acting out, acting in, and primitive forms of communication and psychological defence, such as hysterical identification, projective identification and/or other forms of basic communication typically found at the lower levels of awareness. This paper further goes on to examine, especially using constructivist, but also psychodynamic models, how verbal symbolisation can be helpful in practice with psychosomatic and hysterical disorders. Drawing on our understanding of concentrative and mindfulness meditation the workings of our psychological defences are examined. Constructivist and psychodynamic models are used to describe the distortion of consciousness by these defences??albeit from different perspectives. Both of these psychotherapy approaches are also concerned with the issue of increased awareness via insight, and are therefore complementary to the Eastern notion of enhanced awareness through the practice of meditation and mindfulness. Potential problems with meditation are discussed, as well as limitations to the ??talking cure????as verbalisation can also be used as a higher order cognitive defence, as observed in rationalisation??as well as in the higher service of the expansion of awareness.     

La pleine conscience incarnée : un concept unificateur entre les traditions orientales et occidentales de la pleine conscience

ObjectiveThe interest in mindfulness as a concept continues to grow as shown in the increase in the number of publications pertaining to mindfulness in the last four decades. This increase is also a reflection of the fact that the term “mindfulness” is currently used as an umbrella for a variety of approaches that assign different meanings to the same word. Although differences among varying conceptualizations and definitions of “mindfulness” have been previously highlighted, few efforts have attempted to compare these varying conceptual approaches as a means to address commonalties between them. Therefore, the objective of this paper is to review different conceptualizations of mindfulness in order to understand their common and distinctive components.MethodIn order to investigate commonalities and distinctions among different mindfulness conceptualizations, we conducted a thorough qualitative review of theoretical and empirical papers belonging to three approaches in mindfulness: Eastern Buddhist traditions, Western modern mindfulness meditation programs, and Langerian mindfulness. Each of these approaches is presented first at a conceptual level (i.e., how it defines mindfulness) and then at a practical level (i.e., how to operationalize mindfulness). Empirical research pertaining to the effectiveness of each approach is presented and discussed. As Buddhism incorporates different schools of thoughts, this paper focuses primarily on the conceptualization of mindfulness outlined within Theravada Buddhism. It operationalizes mindfulness through an engagement in intensive and daily meditative practice, which includes both concentrative and open-monitoring meditation. In addition, Buddhism includes a set of ethical principles. Western modern mindfulness meditation programs are conceptualized according to Kabat-Zinn and other western scholars. Definitions varied to some extent according to different scholars, each including a different set of components (e.g., attention, awareness, acceptance, nonjudgement, observation). Western modern mindfulness meditation programs are operationalized though the development and implementation of structured psychosomatic interventions, such as Mindfulness-Based Stress Reduction and Mindfulness-Based Cognitive Therapy. Langerian mindfulness is conceptualized as a general style or mode of functioning through which individuals actively reconstruct their environment by creating new categories or distinctions, and seeking multiple perspectives. Langer operationalized mindfulness through a set of sociocognitive tasks. The role of the body in these three approaches and more specifically the mind-body connection is highlighted through the analysis of clinical, behavioral, and neuroscientific research findings.Results and DiscussionDefinitions from both eastern and western approaches share self-regulation of attention and awareness as central common elements. Both attention and awareness processes increase interoceptive and exteroceptive body awareness and mind-body connection, therefore suggesting a role of embodiment in conceptualizing and operationalizing mindfulness across different approaches. We therefore introduce the new concept of Embodied Mindfulness as an integration of top-down and bottom-up processes and argue for its utility in the empirical study of mindfulness across the three conceptual approaches.ConclusionsThe new notion of embodied mindfulness integrates different conceptualizations of mindfulness by allowing a common understanding of the mechanisms of change across these conceptualizations. This new notion has also both research and clinical implications. This new notion suggests further emphasizing the body and mind-body connection in both studying/measuring mindfulness and in developing/validating clinical interventions.     

Mindfulness-Enhanced Cognitive Behavior Therapy for Problem Gambling: A Controlled Pilot Study

In recent years, mindfulness meditation has shown to be a promising approach for alleviating disability and dysfunction associated with a wide range of medical and psychiatric conditions. To date, there have been no controlled clinical studies of mindfulness for problem gambling (beyond case studies) despite the well-established presence of irrational beliefs and cognitive distortions which would suggest that mindfulness interventions would be particularly suitable. In the present study, a group, five-session, mindfulness intervention was integrated into an empirically-effective cognitive-behavioral therapy for problem gamblers. Compared to a wait list control the mindfulness intervention significantly reduced the severity of gambling, gambling urges and psychiatric symptoms at end-of-treatment. At the 3-month follow-up combining the results of both groups the results were maintained. In addition, a significant decrease in the proportion of the sample meeting criteria for pathological gambling was found. Those individuals who reported some mindfulness practice post-treatment showed significantly better clinical outcomes than did those who did not report any mindfulness practice suggesting that mindfulness did play a role in the outcomes observed. Taking into consideration the multiple methodological limitations of this pilot study there is sufficient evidence to further investigate the potential efficacy of mindfulness interventions for problem gambling.     

A randomized controlled trial of mindfulness meditation versus relaxation training: Effects on distress,positive states of mind,rumination, and distraction

BACKGROUND: Although mindfulness meditation interventions have recently shown benefits for reducing stress in various populations, little is known about their relative efficacy compared with relaxation interventions. PURPOSE: This randomized controlled trial examines the effects of a 1-month mindfulness meditation versus somatic relaxation training as compared to a control group in 83 students (M age = 25; 16 men and 67 women) reporting distress. Method: Psychological distress, positive states of mind, distractive and ruminative thoughts and behaviors, and spiritual experience were measured, while controlling for social desirability. RESULTS: Hierarchical linear modeling reveals that both meditation and relaxation groups experienced significant decreases in distress as well as increases in positive mood states over time, compared with the control group (p < .05 in all cases). There were no significant differences between meditation and relaxation on distress and positive mood states over time. Effect sizes for distress were large for both meditation and relaxation (Cohen's d = 1.36 and .91, respectively), whereas the meditation group showed a larger effect size for positive states of mind than relaxation (Cohen's d =.71 and .25, respectively). The meditation group also demonstrated significant pre-post decreases in both distractive and ruminative thoughts/behaviors compared with the control group (p < .04 in all cases; Cohen's d = .57 for rumination and .25 for distraction for the meditation group), with mediation models suggesting that mindfulness meditation's effects on reducing distress were partially mediated by reducing rumination. No significant effects were found for spiritual experience. CONCLUSIONS: The data suggest that compared with a no-treatment control, brief training in mindfulness meditation or somatic relaxation reduces distress and improves positive mood states. However, mindfulness meditation may be specific in its ability to reduce distractive and ruminative thoughts and behaviors, and this ability may provide a unique mechanism by which mindfulness meditation reduces distress.     

Could EFT Have Saved the Buddha's Marriage? A Reflection on Beckerman and Sarracco

Efforts to integrate mindfulness meditation into existing Western psychoetherpay models are commonplace. While mindfulness techniques may work in concert with other models successfully, the richness of the mindfulness model of encountering the world is often lost. Using Beckerman and Sarracco's case study as an example, this paper explores some of the ways in which a more full integration of the mindfulness model might inform EFT practice.

A treatment model for anxiety-related sexual dysfunctions using mindfulness meditation within a sex-positive framework

In this article, we propose a clinical model for treating anxiety-related sexual dysfunctions that hinges on the use of mindfulness meditation practices. First, theoretical and empirical evidence for anxiety as either a cause or condition of several different sexual dysfunctions is provided. Next, the concept of mindfulness and the research that supports the use of mindfulness meditation practices in addressing anxiety are explained. The inherent link between mindfulness and sex-positivity is also addressed while acknowledging the need to emphasize both mindfulness and sex-positivity in therapy. The proposed model for the treatment of anxiety-related sexual dysfunctions using mindfulness practices within a sex-positive framework is outlined. It utilizes mindfulness-based practices such as body scan meditation and sitting meditation as well as several preexisting sex therapy interventions, including directed masturbation and sensate focus assignments. A case study is provided as an example of the progression of therapy and as a demonstration of the clinical viability of the model. Ultimately, this model illustrates a potential way in which mindfulness practices can be utilized within a sex-positive approach to sex therapy.     

Investigation of mindfulness meditation practitioners with voxel-based morphometry

Mindfulness meditators practice the non-judgmental observationof the ongoing stream of internal experiences as they arise.Using voxel-based morphometry, this study investigated MRI brainimages of 20 mindfulness (Vipassana) meditators (mean practice8.6 years; 2 h daily) and compared the regional gray matterconcentration to that of non-meditators matched for sex, age,education and handedness. Meditators were predicted to showgreater gray matter concentration in regions that are typicallyactivated during meditation. Results confirmed greater graymatter concentration for meditators in the right anterior insula,which is involved in interoceptive awareness. This group differencepresumably reflects the training of bodily awareness duringmindfulness meditation. Furthermore, meditators had greatergray matter concentration in the left inferior temporal gyrusand right hippocampus. Both regions have previously been foundto be involved in meditation. The mean value of gray matterconcentration in the left inferior temporal gyrus was predictableby the amount of meditation training, corroborating the assumptionof a causal impact of meditation training on gray matter concentrationin this region. Results suggest that meditation practice isassociated with structural differences in regions that are typicallyactivated during meditation and in regions that are relevantfor the task of meditation.     

The influence of the spiritual dimension as a complementary therapeutic dynamic in meditation practices and in the field of mental health

ObjectivesThe purpose of this article is to reinstate the framework of the notion of spirituality in the therapeutic field and to underline the potential link between meditation and spirituality, in order to question the potential hindrance to therapeutic effects caused the dissociation of meditation and spirituality. We explore the possible spiritual dimensions of meditation, and, lastly, discuss whether a spiritual dimension is relevant to meditative practice.MethodWe carried out a literature review, selecting the main research dealing with the link between spirituality and meditation.ResultsIt appears that the spiritual dimension has not been taken into account in the therapeutic applications of mindfulness meditation; it would be beneficial for spirituality to be integrated into the meditative process as a complementary tool for the adaptation and the stimulation of practice.DiscussionThe question of the link between spirituality and meditation questions the fact of meditation's having been cut off from its cultural substratum. We suggest that it would be appropriate in certain cases to reactivate this tradition, as well as the role of the psychotherapist in this dynamic.ConclusionThe dimension of spirituality could be a fecund tool in therapeutic accompaniment; integrating spirituality into therapeutic meditation could have positive impacts in terms of patients’ wellbeing and mental health.     

L’approche méditative de concentration au sein des prises en charge thérapeutiques et son impact sur la santé mentale : une revue de la littérature sur des essais cliniques contrôlés et randomisés

Research on meditation in the field of complementary and alternative therapies is increasingly important. Indeed, many works highlight the beneficial effects in terms of physical and mental health of meditation. Within the framework of the two main directions of meditation techniques (concentration and mindfulness), we will focus in this study on concentration meditation (mantra and transcendental meditation). After having framed the notion at a theoretical level, we will develop a review of the literature (randomized, before/after comparison) on this form of practice by precisely targeting transcendent and mantra meditation as well as other forms using only concentration in order to highlight the therapeutic effects of this approach on mental health and to emphasize its effectiveness. However, we will remain cautious about issuing hasty conclusions on the systematic beneficial effects of this practice by highlighting the importance of the methodological limitations that we find in this work for the past 40 years by proposing avenues for improvement.
