<p>In this article, we attempt to distinguish between the properties of moderator and mediator variables at a number of levels. First, we seek to make theorists and researchers aware of the importance of not using the terms moderator and mediator interchangeably by carefully elaborating, both conceptually and strategically, the many ways in which moderators and mediators differ. We then go beyond this largely pedagogical function and delineate the conceptual and strategic implications of making use of such distinctions with regard to a wide range of phenomena, including control and stress, attitudes, and personality traits. We also provide a specific compendium of analytic procedures appropriate for making the most effective use of the moderator and mediator distinction, both separately and in terms of a broader causal system that includes both moderators and mediators.</p>

Summary
This paper reviews the philosophical origins, current scientific evidence, and clinical promise of yoga and mindfulness as complementary therapies for addiction. Historically, there are eight elements of yoga that, together, comprise ethical principles and practices for living a meaningful, purposeful, moral and self-disciplined life. Traditional yoga practices, including postures and meditation, direct attention toward one's health, while acknowledging the spiritual aspects of one's nature. Mindfulness derives from ancient Buddhist philosophy, and mindfulness meditation practices, such as gentle Hatha yoga and mindful breathing, are increasingly integrated into secular health care settings. Current theoretical models suggest that the skills, insights, and self-awareness learned through yoga and mindfulness practice can target multiple psychological, neural, physiological, and behavioral processes implicated in addiction and relapse. A small but growing number of well-designed clinical trials and experimental laboratory studies on smoking, alcohol dependence, and illicit substance use support the clinical effectiveness and hypothesized mechanisms of action underlying mindfulness-based interventions for treating addiction. Because very few studies have been conducted on the specific role of yoga in treating or preventing addiction, we propose a conceptual model to inform future studies on outcomes and possible mechanisms. Additional research is also needed to better understand what types of yoga and mindfulness-based interventions work best for what types of addiction, what types of patients, and under what conditions. Overall, current findings increasingly support yoga and mindfulness as promising complementary therapies for treating and preventing addictive behaviors.

Meditation comprises a series of practices mainly developed in eastern cultures aiming at controlling emotions and enhancing attentional processes. Several authors proposed to divide meditation techniques in focused attention (FA) and open monitoring (OM) techniques. Previous studies have reported differences in brain networks underlying FA and OM. On the other hand common activations across different meditative practices have been reported. Despite differences between forms of meditation and their underlying cognitive processes, we propose that all meditative techniques could share a central process that would be supported by a core network for meditation since their general common goal is to induce relaxation, regulating attention and developing an attitude of detachment from one’s own thoughts. To test this hypothesis, we conducted a quantitative meta-analysis based on activation likelihood estimation (ALE) of 10 neuroimaging studies (91 subjects) on different meditative techniques to evidence the core cortical network subserving meditation. We showed activation of basal ganglia (caudate body), limbic system (enthorinal cortex) and medial prefrontal cortex (MPFC). We discuss the functional role of these structures in meditation and we tentatively propose a neurocognitive model of meditation that could guide future research.

Positive affect elicited in a mother toward her newborn infant may be one of the most powerful and evolutionarily preserved forms of positive affect in the emotional landscape of human behavior. This study examined the neurobiology of this form of positive emotion and in so doing, sought to overcome the difficulty of eliciting robust positive affect in response to visual stimuli in the physiological laboratory. Six primiparous human mothers with no indications of postpartum depression brought their infants into the laboratory for a photo shoot. Approximately 6 weeks later, they viewed photographs of their infant, another infant, and adult faces during acquisition of functional magnetic resonance images (fMRI). Mothers exhibited bilateral activation of the orbitofrontal cortex (OFC) while viewing pictures of their own versus unfamiliar infants. While in the scanner, mothers rated their mood more positively for pictures of their own infants than for unfamiliar infants, adults, or at baseline. The orbitofrontal activation correlated positively with pleasant mood ratings. In contrast, areas of visual cortex that also discriminated between own and unfamiliar infants were unrelated to mood ratings. These data implicate the orbitofrontal cortex in a mother's affective responses to her infant, a form of positive emotion that has received scant attention in prior human neurobiological studies. Furthermore, individual variations in orbitofrontal activation to infant stimuli may reflect an important dimension of maternal attachment.

Studies of homework effects in psychotherapy outcome have produced inconsistent results. Although these findings may reflect the comparability of psychotherapy with and without homework assignments, many of these studies may not have been sensitive enough to detect the effects sizes (ESs) likely to be found when examining homework effects. The present study evaluated the power of homework research and showed that, on average, current power levels are relatively weak in controlled studies ranging from 0.58 for large ESs to 0.09 for small ESs. Thus, inconsistent findings between studies may very well be due to low statistical power.

Individuals with fragile X syndrome (FXS) commonly display characteristics of social anxiety, including gaze aversion, increased time to initiate social interaction, and difficulty forming meaningful peer relationships. While neural correlates of face processing, an important component of social interaction, are altered in FXS, studies have not examined whether social anxiety in this population is related to higher cognitive processes, such as memory. This study aimed to determine whether the neural circuitry involved in face encoding was disrupted in individuals with FXS, and whether brain activity during face encoding was related to levels of social anxiety. A group of 11 individuals with FXS (5 M) and 11 age- and gender-matched control participants underwent fMRI scanning while performing a face encoding task with online eye-tracking. Results indicate that compared to the control group, individuals with FXS exhibited decreased activation of prefrontal regions associated with complex social cognition, including the medial and superior frontal cortex, during successful face encoding. Further, the FXS and control groups showed significantly different relationships between measures of social anxiety (including gaze-fixation) and brain activity during face encoding. These data indicate that social anxiety in FXS may be related to the inability to successfully recruit higher level social cognition regions during the initial phases of memory formation.

<p>In this meta-analysis, we give a comprehensive overview of the effects of meditation on psychological variables that can be extracted from empirical studies, concentrating on the effects of meditation on nonclinical groups of adult meditators. Mostly because of methodological problems, almost ¾ of an initially identified 595 studies had to be excluded. Most studies appear to have been conducted without sufficient theoretical background. To put the results into perspective, we briefly summarize the major theoretical approaches from both East and West. The 163 studies that allowed the calculation of effect sizes exhibited medium average effects ( = .28 for all studies and = .27 for the n = 125 studies from reviewed journals), which cannot be explained by mere relaxation or cognitive restructuring effects. In general, results were strongest (medium to large) for changes in emotionality and relationship issues, less strong (about medium) for measures of attention, and weakest (small to medium) for more cognitive measures. However, specific findings varied across different approaches to meditation (transcendental meditation, mindfulness meditation, and other meditation techniques). Surprisingly, meditation experience only partially covaried with long-term impact on the variables examined. In general, the dependent variables used cover only some of the content areas about which predictions can be made from already existing theories about meditation; still, such predictions lack precision at present. We conclude that to arrive at a comprehensive understanding of why and how meditation works, emphasis should be placed on the development of more precise theories and measurement devices.</p>

<p>Psychotherapeutic interventions containing training in mindfulness meditation have been shown to help participants with a variety of somatic and psychological conditions. Mindfulness-based cognitive therapy (MBCT) is a meditation-based psychotherapeutic intervention designed to help reduce the risk of relapse of recurrent depression. There is encouraging early evidence from multi-centre randomized controlled trials. However, little is known of the process by which MBCT may bring therapeutic benefits. This study set out to explore participants' accounts of MBCT in the mental-health context. Seven participants were interviewed in two phases. Interview data from four participants were obtained in the weeks following MBCT. Grounded theory techniques were used to identify several categories that combine to describe the ways in which mental-health difficulties arose as well as their experiences of MBCT. Three further participants who have continued to practise MBCT were interviewed so as to further validate, elucidate and extend these categories. The theory suggested that the preconceptions and expectations of therapy are important influences on later experiences of MBCT. Important areas of therapeutic change ('coming to terms') were identified, including the development of mindfulness skills, an attitude of acceptance and 'living in the moment'. The development of mindfulness skills was seen to hold a key role in the development of change. Generalization of these skills to everyday life was seen as important, and several ways in which this happened, including the use of breathing spaces, were discussed. The study emphasized the role of continued skills practice for participants' therapeutic gains. In addition, several of the concepts and categories offered support to cognitive accounts of mood disorder and the role of MBCT in reducing relapse.</p>

<p>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.</p>

This experiment was designed to assess the differential impact of initially presenting affective information to the left versus right hemisphere on both the perception of and response to the input. Nineteen right-handed subjects were presented with faces expressing happiness and sadness. Each face was presented twice to each visual field for an 8-sec duration. The electro-oculogram (EOG) was monitored and fed back to subjects to train them to keep their eyes focused on the central fixation point as well as to eliminate trials confounded by eye movement artifact. Following each slide presentation, subjects rated the intensity of the emotional expression depicted in the face and their emotional reaction to the face on a series of 7-point rating scales. Subjects reported perceiving more happiness in response to stimuli initially presented to the left hemisphere (right visual field) compared to presentations of the identical faces to the right hemisphere (left visual field). This effect was predominantly a function of ratings on sad faces. A similar, albeit less robust, effect was found on self-ratings of happiness (the degree to which the face elicited the emotion in the viewer). These data challenge the view that the right hemisphere is uniquely involved in all emotional behavior. The implications of these findings for theories concerning the lateralization of emotional behavior are discussed.

Featuring accounts by practitioners living everyday lives, this introduction to Vipassana meditation provides a way for readers to learn more about its benefits. Explained is what takes place before, during, and after a ten-day silent meditation retreat. Each participant follows the same discipline: silence, a basic moral code known as the five precepts, a prescribed timetable, a vegetarian diet, and a commitment to practicing only what is taught at the retreat. This first-person account of the retreat reveals the challenges and benefits of facing reality head-on through direct observation and of learning to observe instead of reacting to thoughts, emotions, and sensations. In addition, the ways in which Vipassana meditation techniques are applied to individuals, institutions, children, prisoners, work places, and fields of science and social action are examined. Although based on the teachings of the Buddha, the practice of Vipassana as illustrated in this book has broad appeal to other religious and nonsectarian audiences.

<p>This exploratory study examined differences in normal narcissism between mindfulness meditation practitioners (n = 76), comprised of men (30%) and women (70%) between the ages of 18 and 79, and a control group (n = 36) of nonmeditators with spiritual interests, comprised of men (19%) and women (81%) between the ages of 31 and 78. Normal narcissism was defined as a concentration of psychological interest upon the representational self (i.e., ego-identity). Quantitative analysis was conducted using the Kruskal-Wallis ANOVA and Fisher's Least Significant Differences (LSD) test. The study's measures included (a) the Narcissistic Personality Inventory (NPI) measuring normal, overt narcissism and (b) the Transpersonally Oriented Narcissism Questionnaire (TONQ)--a piloted measure of normal narcissism designed to assess overt, covert, and transformative aspects of 4 core narcissistic features: (a) self-centeredness, (b) grandiosity, (c) need-for-mirroring/admiration, and (d) emptiness. Quantitative results are informed by qualitative analysis utilizing heuristic, hermeneutical, and phenomenological principles. Results indicate no differences in NPI scores among the various meditator variables: (a) years of practice, (b) amount of meditation per week, (c) duration of meditation per sitting, and (d) retreat experience or between meditators ( n = 76) and control (n = 36). Differences exist among all 4 meditator variables (a) - (d) and control group regarding (a) overall transformation of narcissism, (b) emptiness as the ultimate potential (e.g., sunnata), and (c) self-centeredness, with controls having higher means than meditators on overall narcissism-transformation and narcissistic emptiness, and lower means on self-centeredness subscales. Differences exist between 3 meditator variables and control regarding narcissistic emptiness, with controls having higher means than meditators. Differences exist between 2 meditator variables and control regarding transforming grandiosity, where controls report higher means than meditators. This exploratory research demonstrates that the transpersonal study of narcissism is possible despite the many methodological complications and numerous theoretical questions it raises.</p>

Selective attention has been shown to bias sensory processing in favor of relevant stimuli and against irrelevant or distracting stimuli in perceptual tasks. Increasing evidence suggests that selective attention plays an important role during working memory maintenance, possibly by biasing sensory processing in favor of to-be-remembered items. In the current study, we investigated whether selective attention may also support working memory by biasing processing against irrelevant and potentially distracting information. Event-related potentials (ERPs) were recorded while subjects (n = 22) performed a delayed-recognition task for faces and shoes. The delay period was filled with face or shoe distractors. Behavioral performance was impaired when distractors were congruent with the working memory domain (e.g., face distractor during working memory for faces) relative to when distractors were incongruent with the working memory domain (e.g., face distractor during shoe working memory). If attentional biasing against distractor processing is indeed functionally relevant in supporting working memory maintenance, perceptual processing of distractors is predicted to be attenuated when distractors are more behaviorally intrusive relative to when they are nonintrusive. As such, we predicted that perceptual processing of distracting faces, as measured by the face-sensitive N170 ERP component, would be reduced in the context of congruent (face) working memory relative to incongruent (shoe) working memory. The N170 elicited by distracting faces demonstrated reduced amplitude during congruent versus incongruent working memory. These results suggest that perceptual processing of distracting faces may be attenuated due to attentional biasing against sensory processing of distractors that are most behaviorally intrusive during working memory maintenance.

<p>Recent literature has described how the capacity for concurrent self-assessment—ongoing moment-to-moment self-monitoring—is an important component of the professional competence of physicians. Self-monitoring refers to the ability to notice our own actions, curiosity to examine the effects of those actions, and willingness to use those observations to improve behavior and thinking in the future. Self-monitoring allows for the early recognition of cognitive biases, technical errors, and emotional reactions and may facilitate self-correction and development of therapeutic relationships. Cognitive neuroscience has begun to explore the brain functions associated with self-monitoring, and the structural and functional changes that occur during mental training to improve attentiveness, curiosity, and presence. This training involves cultivating habits of mind such as experiencing information as novel, thinking of “facts” as conditional, seeing situations from multiple perspectives, suspending categorization and judgment, and engaging in self-questioning. The resulting awareness is referred to as mindfulness and the associated moment-to-moment self-monitoring as mindful practice—in contrast to being on “automatic pilot” or “mindless” in one's behavior. This article is a preliminary exploration into the intersection of educational assessment, cognitive neuroscience, and mindful practice, with the hope of promoting ways of improving clinicians' capacity to self-monitor during clinical practice, and, by extension, improve the quality of care that they deliver.</p>

<p>Studied the different effects of yoga and psychomotor activity on a coding task, with 34 children referred to a learning center as Ss. They received a baseline period, a control period involving a fine motor task, an experimental treatment, another control period, a treatment reversal, and a control period. The results indicate that order of treatment had no effect on the results. Furthermore, coding scores in the 2nd half of the experiment were higher than those in the 1st half. There was no difference in the effect on performance of yoga and gross motor activities. Irrespective of which treatment was given, scores after treatment were significantly higher than those during the control periods. There are implications for physical education programming in elementary schools.</p>

"The practice of contemplation is one of the great spiritual arts," writes Martin Laird in A Sunlit Absence. "Not a technique but a skill, it harnesses the winds of grace that lead us out into the liberating sea of silence." In this companion volume to his bestselling Into the Silent Land, Laird focuses on a quality often overlooked by books on Christian meditation: a vast and flowing spaciousness that embraces both silence and sound, and transcends all subject/object dualisms. Drawing on the wisdom of great contemplatives from St. Augustine and St. Teresa of Avila to St. Hesychios, Simone Weil, and many others, Laird shows how we can uncover the deeper levels of awareness that rest within us like buried treasure waiting to be found. The key insight of the book is that as our practice matures, so will our experience of life's ordeals, sorrows, and joys expand into generous, receptive maturity. We learn to see whatever difficulties we experience in meditation--boredom, lethargy, arrogance, depression, grief, anxiety--not as obstacles to be overcome but as opportunities to practice surrender to what is. With clarity and grace Laird shows how we can move away from identifying with our turbulent, ever-changing thoughts and emotions to the cultivation of a "sunlit absence"--the luminous awareness in which God's presence can most profoundly be felt. Addressed to both beginners and intermediates on the pathless path of still prayer, A Sunlit Absence offers wise guidance on the specifics of contemplative practice as well as an inspiring vision of the purpose of such practice and the central role it can play in our spiritual lives.

<p>Objective. To critically review the evidence on the effectiveness of complementary therapies for patients with RA. Randomized controlled trials, published in English up to May 2011, were identified using systematic searches of bibliographic databases and searching of reference lists. Information was extracted on outcomes and statistical significance in comparison with alternative treatments and reported side effects. The methodological quality of the identified studies was determined using the Jadad scoring system. All outcomes were considered but with a focus on patient global assessment and pain reporting. Eleven eligible trials were identified covering seven therapies. Three trials that compared acupuncture with sham acupuncture reported no significant difference in pain reduction between the groups but one out of two reported an improvement in patient global assessment. Except for reduction in physicianʼs global assessment of treatment and disease activity reported in one trial, no other comparative benefit of acupuncture was seen. There were two studies on meditation and one each on autogenic training, healing therapy, progressive muscle relaxation, static magnets and tai chi. None of these trials reported positive comparative effects on pain but some positive effects on patient global assessment were noted at individual time points in the healing therapy and magnet therapy studies. A small number of other outcomes showed comparative improvement in individual trials. There were no reports of major adverse events. The very limited evidence available indicates that for none of the practitioner-based complementary therapies considered here is there good evidence of efficacy or effectiveness in the management of RA</p>
