Meditation is a mental training, which involves attention and the ability to maintain focus on a particular object. In this study we have applied a specific attentional task to simply measure the performance of the participants with different levels of meditation experience, rather than evaluating meditation practice per se or task performance during meditation. Our objective was to evaluate the performance of regular meditators and non-meditators during an fMRI adapted Stroop Word-Colour Task (SWCT), which requires attention and impulse control, using a block design paradigm. We selected 20 right-handed regular meditators and 19 non-meditators matched for age, years of education and gender. Participants had to choose the colour (red, blue or green) of single words presented visually in three conditions: congruent, neutral and incongruent. Non-meditators showed greater activity than meditators in the right medial frontal, middle temporal, precentral and postcentral gyri and the lentiform nucleus during the incongruent conditions. No regions were more activated in meditators relative to non-meditators in the same comparison. Non-meditators showed an increased pattern of brain activation relative to regular meditators under the same behavioural performance level. This suggests that meditation training improves efficiency...

Introdução: A insônia está entre os mais frequentes transtornos que afetam a população na contemporaneidade, devido a mudanças hormonais e psicossociais importantes é muito prevalente na perimenopausa. Há uma relação ainda pouco estudada entre eficiência do sono e prática meditativa. Os tratamentos utilizados para insônia normalmente são de alto custo e paliativos. Objetivo: Avaliar o efeito da meditação na insônia (causada por sintomas característicos da perimenopausa) e qualidade de vida nesta fase da vida. Método: Ensaio clínico controlado para avaliar os efeitos da meditação em mulheres com insônia no período da perimenopausa e o impacto na qualidade de vida em 8 semanas de intervenção. O estudo foi realizado de abril a julho de 2013 com 33 mulheres na perimenopausa de idade entre 40 a 55 anos em 3 unidades de órgão público no município de São Paulo, SP. As participantes foram divididas aleatoriamente em dois grupos, um que praticou somente Higiene do Sono-HS (n=15) e outro que praticou Meditação + Higiene do Sono-M+HS (n=18). Foram realizados encontros semanais com as participantes de ambos os grupos para pratica de meditação em grupo e/ou critérios de higiene do sono. O grupo M+HS também realizou prática diária de meditação. Para avaliar a significância estatística das diferenças de médias antes e depois das intervenções em cada grupo foi utilizado o teste de Wilcoxon. Resultados: Houve melhora da insônia em ambos os grupos...

O crescimento do número de idosos no Brasil nos confronta com o desafio de olhar para o envelhecimento de forma diferente. No que concerne à Psicologia, tal exercício é essencial para (re)pensarmos a prática ampliando-a à população idosa. Tendo como hipótese a ocorrência de mudanças na imagem corporal e considerando o possível conflito mente-corpo no envelhecimento, o estudo teve como objetivo avaliar os efeitos de uma prática de meditação na autoimagem de idosos analisando conteúdo verbal e conteúdo gráfico; foi utilizado um roteiro de entrevista e o Procedimento de Desenho-Estória com Tema (Vaisberg, 1999); foi solicitado aos participantes que realizassem o desenho de uma pessoa idosa, que foi comparado com suas respostas sobre percepção do envelhecimento/velhice. Os dados foram analisados antes e depois da intervenção do curso de meditação. O referencial psicanalítico serviu como base para a análise dos dados, que considera a existência de aspectos inconscientes e a presença de mecanismos de defesa permeando o funcionamento psíquico. Os instrumentos permitiram visualizar diferenças entre os dados, com contradição no teor das respostas gráficas e verbais; os resultados mostraram essencialmente mudanças significativas referentes aos desenhos; o conteúdo verbal permaneceu praticamente o mesmo nos dois momentos; nas características gráficas houve expansão...

Emotion regulation is the capacity to control the way in which people attend, perceive, process and react to emotional information. Practitioners of sitting and silent meditation develop a greater control of their mental processes, culminating in regulatory abilities that lead to well-being and emotional balance. In this paper we reviewed evidence from recent studies on neurophysiology and cognitive psychology on emotion regulation-focusing on negative emotions-and meditation in order to discuss their intertwining. This critical review showed that controlling attention and fostering a relaxation state are the main mechanisms for the interaction between emotion regulation and meditation. Importantly, it is suggested that the effects of meditation on emotion regulation should be conceptualized separately as those taking effect during the practice and those occurring as an outcome of such practice. Finally, it is highlighted that meditation should be conceived as a particular type of emotion regulation strategy, and that further studies comparing these strategies more directly are warranted.

Increasing data suggest that meditation impacts stress-related physiological processes relevant to health and disease. For example, our group recently reported that the practice of compassion meditation was associated with reduced innate immune (plasma interleukin [IL]-6) and subjective distress responses to a standardized laboratory psychosocial stressor (Trier Social Stress Test [TSST]). However, because we administered a TSST after, but not prior to, meditation training in our initial study, it remained possible that associations between practice time and TSST outcomes reflected the fact that participants with reduced stress responses prior to training were more able to practice compassion meditation, rather than that meditation practice reduced stress responses. To help resolve this ambiguity, we conducted the current study to evaluate whether innate immune, neuroendocrine and behavioral responses to a TSST conducted prior to compassion meditation training in an independent sample of 32 medically health young adults would predict subsequent amount of meditation practice time during a compassion meditation training protocol identical to the one used in our first study. No associations were found between responses to a TSSTadministered prior to compassion meditation training and subsequent amount of meditation practice...

Meditation proficiency is related to trait-like (learned) effects on brain function, developed over time. Previous studies show increases in EEG power in lower frequency bands (theta, alpha) in experienced meditators in both meditation states and baseline conditions. Higher gamma band power has been found in advanced Buddhist meditators, yet it is not known if this occurs in Yoga meditation practices. This study used eLORETA to compare differences in cortical source activity underlying scalp EEG from intermediate (mean experience 4 years) and advanced (mean experience 30 years) Australian meditators from the Satyananda Yoga tradition during a body-steadiness meditation, mantra meditation, and non-meditation mental calculation condition. Intermediate Yoga meditators showed greater source activity in low frequencies (particularly theta and alpha1) during mental calculation, body-steadiness and mantra meditation. A similar spatial pattern of significant differences was found in all conditions but the number of significant voxels was double during body-steadiness and mantra meditation than in the non-meditation (calculation) condition. These differences were greatest in right (R) superior frontal and R precentral gyri and extended back to include the R parietal and occipital lobes. Advanced Yoga meditators showed greater activity in high frequencies (beta and especially gamma) in all conditions but greatly expanded during meditation practice. Across all conditions (meditation and non-meditation) differences were greatest in the same regions: R insula...

There has been a growing interest in understanding how contemplative practices affect brain functional organization. However, most studies have restricted their exploration to predefined networks. Furthermore, scientific comparisons of different contemplative traditions are largely lacking. Here we explored differences in whole brain resting state functional connectivity between experienced yoga practitioners, experienced meditators, and matched controls. Analyses were repeated in an independent sample of experienced meditators and matched controls. Analyses utilizing Network-Based Statistics (Zalesky et al., 2010) revealed difference components for yoga practitioners > controls and meditators > controls in which the right caudate was a central node. Follow up analyses revealed that yoga practitioners and meditators had significantly greater degree centrality in the caudate than controls. This greater degree centrality was not driven by single connections but by greater connectivity between the caudate and numerous brain regions. Findings of greater caudate connectivity in meditators than in controls was replicated in an independent dataset. These findings suggest that yoga and meditation practitioners have stronger functional connectivity within basal ganglia cortico-thalamic feedback loops than non-practitioners. Although we could not provide evidence for its mechanistic role...

La douleur est une expérience multidimensionnelle comportant des aspects sensoriels, émotionnels et cognitifs. Il a été montré que cette expérience peut être modulée par des facteurs psychologiques ou des interventions cognitives comme l’attention, la distraction, l’hypnose ou les attentes. La tradition orientale suggère également que la pratique de la méditation pourrait avoir des effets analgésiques. D’un point de vue théorique, plusieurs mécanismes pourraient expliquer ces effets. Cependant, très peu d’études ont testé ces hypothèses. Les études présentées dans cette thèse avaient donc pour objectif d’examiner les mécanismes analgésiques de la méditation. Dans un premier temps, une étude psychophysique a été réalisée afin de comparer les réponses à la douleur entre des adeptes de la méditation Zen et des sujets contrôles, dans différentes conditions attentionnelles. Durant la condition attentionnelle de type « mindful », les adeptes de la méditation ont présenté une plus faible sensibilité à la douleur, des réponses attentionnelles à la douleur atypiques et une diminution de la perception de la douleur associée à l’entraînement à la méditation. Une deuxième étude a été réalisée en imagerie par résonance magnétique fonctionnelle (IRMf) avec des groupes de participants similaires. Dans une condition sans méditation...

While overall life expectancy has been increasing, the human brain still begins deteriorating after the first two decades of life and continues degrading further with increasing age. Thus, techniques that diminish the negative impact of aging on the brain are desirable. Existing research, although scarce, suggests meditation to be an attractive candidate in the quest for an accessible and inexpensive, efficacious remedy. Here, we examined the link between age and cerebral gray matter re-analyzing a large sample (n = 100) of long-term meditators and control subjects aged between 24 and 77 years. When correlating global and local gray matter with age, we detected negative correlations within both controls and meditators, suggesting a decline over time. However, the slopes of the regression lines were steeper and the correlation coefficients were stronger in controls than in meditators. Moreover, the age-affected brain regions were much more extended in controls than in meditators, with significant group-by-age interactions in numerous clusters throughout the brain. Altogether, these findings seem to suggest less age-related gray matter atrophy in long-term meditation practitioners.; Nicolas Cherbuin is funded by Australian Research Council fellowship number 120100227.

The tendency to experience shame or guilt is associated differentially with anxiety, depression and substance abuse, with shame being associated with greater psychopathology. Recent interventions designed to decrease shame emphasize mindfulness or self-compassion. The present study investigated correlational relationships of shame-proneness and guilt-proneness with mindfulness and with self-compassion in undergraduate participants. Shame-proneness was strongly negatively correlated with all facets of mindfulness and with self-compassion, while guilt-proneness was weakly positively correlated with self-compassion and some facets of mindfulness. Hierarchical regression analysis showed that shame-proneness was predicted by self-compassion but not by mindfulness. More frequent meditation was associated with greater mindfulness and self-compassion and lower shame-proneness, but not guilt-proneness. Limitations of the study and implications of the findings for interventions to reduce shame are discussed.; Hannah Woods, Michael Proeve

AbstractMeditation has been associated with positive psychological outcomes, but few studies have investigated brief interventions. This randomized controlled pilot study assessed the effects of five days of focused meditation on positive and negative affect, state and trait anxiety, as well as concentrated attention in a nonclinical sample distributed in two groups (experimental = 14, 51.8% female, Mage= 23.9; control = 19, 62% female, Mage= 24.9). The instruments used were the Positive Affect and Negative Affect Scale, State and Trait Anxiety Inventory, and the Concentrated Attention Test. The meditation group reduced negative affect and trait anxiety, and also improved correct responses on the attention test, relative to controls. These preliminary findings indicate that even short focused meditation training may help improve some psychological variables. It is discussed that the early manifestation of these benefits may be especially relevant to strengthen the motivation to continue and practice regularly.

This study examined the use of mindfulness meditation in educator growth and professional development. The purpose was to create recommendations for an effective mindfulness meditation practice for educators. To this end, as the researcher is an educator as well as an experienced mindfulness meditation practitioner, the research methodology was self-study through narrative inquiry. The exploration of mindfulness meditation on the researcher’s personal and professional development was viewed through the lenses of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory. These theories provided an analytical framework that guided this research. Themes were drawn from the exploration and connected with academic literature. The results were a mindfulness meditation framework for educators that is based on the Socratic Method, and utilizes the conceptual frameworks of Maslow’s hierarchy of needs and Mezirow’s transformational learning theory.

La méditation par le ‘mindfulness’ favorise la stabilité émotionelle, mais les mécanismes neuroneux qui sous-tendent ces effets sont peu connus. Ce projet investiga l’effet du ‘mindfulness’ sur les réponses cérébrales et subjectives à des images négatives, positives et neutres chez des méditants expérimentés et des débutants au moyen de l’imagerie par résonance magnétique fonctionnelle (IRMf). Le ‘mindfulness’ atténua l’intensité émotionelle via différents mécanismes cérébraux pour chaque groupe. Comparés aux méditants, les débutants manifestèrent une déactivation de l’amygdale en réponse aux stimuli émotifs durant le ‘mindfulness’. Comparés aux débutants, les méditants exhibèrent une déactivation de régions du réseau du mode par défaut (RMD) pendant le ‘mindfulness’ pour tous stimuli (cortex médian préfrontal [CMP], cortex cingulaire postérieur [CCP]). Le RMD est constitué de régions fonctionnellement connectées, activées au repos et déactivées lors de tâches explicites. Cependant, nous ne connaissons pas les impacts de l’entraînement par la méditation sur la connectivité entre régions du RMD et si ces effets persistent au-delà d’un état méditatif. La connectivité fonctionnelle entre régions du RMD chez les méditants et débutants au repos fut investiguée au moyen de l’IRMf. Comparés aux débutants...

Esta dissertação tem como objeto a formação do sujeito cartesiano nas Meditações Metafísicas, partindo da leitura de Michel Foucault. Ao analisar a obra maior de Descartes, especialmente com o texto "Mon corps, ce papier, ce feu" (1972), Foucault enfatizou a trama "ascética" do discurso meditativo, que se cruza com a trama demonstrativa. É pelo exercício (ascese) que o sujeito se forma ou se transforma pelas enunciações discursivas. O conceito de meditação, seu aspecto ascético, é portanto o núcleo deste trabalho, que foi dividido em três partes: a primeira faz uma análise do conceito de linguagem na obra cartesiana, visando explicar se há um ideal estilístico propugnado pelo filósofo francês e quais os motivos que o levaram a optar pela forma discursiva 'meditação'. A segunda parte analisa o 'exercício meditativo' a partir de uma dupla perspectiva: de um lado descreve a meditação como uma prática que engloba um conjunto de regras que constituem uma arte (techné); por outro, analisa a meditação como forma discursiva ou gênero literário/filosófico, indicando as origens do discurso cartesiano nas obras legadas pela literatura cristã. O objetivo deste segundo capítulo é mostrar os pontos de continuidade da filosofia cartesiana com a tradição mas...

Este trabalho procura discutir a relação entre meditação budista e treinamento de atores. Há mais de um século o budismo tem sido objeto de estudo de acadêmicos da Europa e América. Ao longo desse período um vasto material foi produzido e disponibilizado falando sobre a filosofia, a religião e as práticas culturais ligadas as diferentes tradições budistas. Especialmente os estudos de Varela e Wallace apontam para uma abordagem mais ampla do diálogo dessa tradição com a ciência, aprofundando o debate acerca das suas contribuições para áreas como a neurologia, a neuropsicologia e a epistemologia científica. Também no âmbito da pesquisa em teatro os estudos interculturais e interdisciplinares cresceram ao longo do último século e, entre eles, o budismo começa a ganhar importância. Na maioria desses estudos, porém, o foco tem sido orientado pelo instrumentalismo, uma perspectiva que define a validade de uma explicação a partir do seu uso, não importando tanto o quê das coisas, mas o como elas funcionam. Nessa direção muitas investigações têm sido orientadas por uma sobrevalorização da "técnica" e por um discurso cientificista, abordando as diferentes tradições a partir de critérios de uso. Este texto se propõe a explorar algumas das perspectivas que os estudos sobre a meditação budista podem trazer para o pensamento acerca do treinamento de atores como prática de formação. Assim...

A meditação, caracterizada como o treino da atenção plena à consciência do momento presente, tem sido associada a um maior bem-estar mental, emocional e físico. Este estudo investigou como os praticantes da meditação passiva – sentada e silenciosa – percebem o impacto de sua prática no seu cotidiano. Ao todo, 105 participantes os quais frequentavam havia no mínimo um mês algum centro de meditação da cidade de Porto Alegre responderam a uma questão aberta sobre como a meditação se reflete em suas vidas. Através da análise de conteúdo, foram identificadas seis categorias, representando os benefícios citados: cognitivos, emocionais, físicos, espirituais, sociais e outros. Através da regressão de Poisson, foram observados alguns fatores associados às categorias identificadas. Conclui-se que a experiência subjetiva da meditação se reflete de diversas formas, com predominância de benefícios cognitivos e emocionais, e que esta prática pode constituir uma ferramenta para o desenvolvimento psicológico saudável.; Meditation, characterized as the training of full attention to the consciousness of the present moment, has been associated with greater mental, emotional and physical well-being.

Background: Interoception refers to the conscious perception of body signals. Mindfulness is a meditation practice that encourages individuals to focus on their internal experiences such as bodily sensations, thoughts, and emotions. In this study, we selected a behavioral measure of interoceptive sensitivity (heartbeat detection task, HBD) to compare the effect of meditation practice on interoceptive sensitivity among long term practitioners (LTP), short term meditators (STM, subjects that completed a Mindfulness-Based Stress Reduction (MBSR) program) and controls (non-meditators). All participants were examined with a battery of different tasks including mood state, executive function and social cognition tests (emotion recognition, empathy and theory of mind). Findings: Compared to controls, both meditators’ groups showed lower levels of anxiety and depression, but no improvement in executive function or social cognition performance was observed (except for lower scores compared to controls only in the personal distress dimension of empathy). More importantly, meditators’ performance did not differ from that of nonmeditators regarding cardiac interoceptive sensitivity. Conclusion: Results suggest no influence of meditation practice in cardiac interoception and in most related social cognition measures. These negative results could be partially due to the fact that awareness of heartbeat sensations is not emphasized during mindfulness/vipassana meditation and may not be the best index of the awareness supported by the practice of meditation.; Fil: Melloni...

This is the author accepted manuscript. The final version is available from Sage via http://dx.doi.org/10.1177/0306624X15602514; This article presents results from a systematic review and two meta-analyses that examine whether prison yoga and meditation programs are significantly related to increased psychological well-being and improvements in the behavioural functioning of prisoners. Comprehensive searches of the empirical literature were conducted up to December 2014. Participants who completed yoga or meditation program in prison experienced a small increase in their psychological well-being (Cohen?s d = 0.46, 95% confidence interval [CI] = [0.39, 0.54]) and a small improvement in their behavioural functioning (Cohen?s d = 0.30, 95% CI = [0.20, 0.40]). Moderator analyses suggested that there was a significant difference in effect sizes for programs of longer duration and less intensity, compared with those that were shorter and more intensive, for psychological well-being. Programs of longer duration had a slightly larger positive effect on behavioural functioning (d = 0.424), compared with more intensive programs (d = 0.418). Overall, the evidence suggests that yoga and meditation have favourable effects on prisoners.

Breast cancer is the most common type of cancer among women in the United States. Despite more women undergoing treatment and increased survival rates, many women continue to suffer from emotional distress and physical symptoms associated with treatments for breast cancer (e.g., surgery). To date, there has been limited research investigating the efficacy of psychosocial interventions for breast cancer patients during the surgical time frame. This randomized controlled pilot study examined the effect of a lovingkindness meditation intervention on key psychological and physical outcomes surrounding breast surgery. Sixty women undergoing surgery were randomly assigned to one of three treatment conditions at breast biopsy: 1) lovingkindness meditation, 2) music, 3) standard care. Assessments of emotional distress, physical symptoms, and positive psychosocial resources occurred prior to patients' biopsy, following their biopsy, one week after receipt of their biopsy results, and one week following breast surgery. Multilevel model analyses demonstrated that lovingkindness meditation significantly improved anxiety, pain, self-compassion, emotional suppression, mindfulness, social isolation, and heart rate levels over time compared to control conditions. These results support the efficacy of a brief lovingkindness meditation intervention for breast cancer patients during the surgical time frame. The implications of these findings on future research...

 Sitting and silent meditation can be described as a mental training, which has been traditionally associated with well-being. The growing scientific interest in it has helped confirm this association through various methodologies. This work aims to discuss the interface between some of the tenets of meditation and psychological science concerning well-being, as well as empirical results supporting the effects of this practice on positive emotional experiences. It also proposes that this relationship is mediated by three main and interdependent psychological processes: relaxation, metacognition/ mindfulness, and self-regulation. We discuss that the investigation of such mechanisms and the general effects of meditation can contribute to its application in the field of psychology, as well as to the development of the psychological science. Keywords: meditation; well-being; relaxation; mindfulness; self-regulation.;  A meditação sentada e silenciosa pode ser descrita como um treinamento mental, o qual tem sido tradicionalmente associado ao bem-estar.
