Research on the anatomical bases of interhemispheric interaction, including individual differences in corpus callosum (CC) anatomy, is reviewed. These anatomical findings form the basis for the discussion of two major themes. The first considers interhemispheric transfer time (IHTT) and related issues. These include varieties of IHTT and possible directional asymmetries of IHTT. Evidence suggests that pathological variations in IHTT may have cognitive consequences. The second involves conditions under which interhemispheric interaction is necessary and beneficial. The data suggest that when both hemispheres have some competence at a difficult task, there is a benefit to interhemispheric interaction. The role of the CC in the dynamic distribution of attention may be particularly relevant to this advantage. Throughout the article reference is made to individual differences and developmental changes associated with interhemispheric interaction.

Neurosurgical treatment of psychiatric disorders has been influenced by evolving neurobiological models of symptom generation. The advent of functional neuroimaging and advances in the neurosciences have revolutionized understanding of the functional neuroanatomy of psychiatric disorders. This article reviews neuroimaging studies of depression from the last 3 decades and describes an emerging neurocircuitry model of mood disorders, focusing on critical circuits of cognition and emotion, particularly those networks involved in the regulation of evaluative, expressive and experiential aspects of emotion. The relevance of this model for neurotherapeutics is discussed, as well as the role of functional neuroimaging of psychiatric disorders.

<p>The purpose of this theoretical study was to investigate the potential compatibility of existential-humanistic psychotherapy and Buddhist meditation as they are practiced in the contemporary Western world. The fundamental philosophies and practices of Buddhist meditation, drawn from Tibetan, Zen, and Vipassana sources in Western publication, were presented. The principles and practices of existential-humanistic psychotherapy, represented by the works of May, Rogers, and Maslow, were next brought forth. After these presentations, the major ideologies and techniques of each discipline were compared and contrasted, with a view toward examining their essential similarities and significant points of departure. Following this examination, contemporary practices in the synthesis of existential-humanistic psychotherapy and Buddhist meditation were discussed as they exist in current usage in therapeutic situations. The voices of persons expressing opposition to a synthesis of Buddhist meditation and existential-humanistic psychotherapy were also brought forth for consideration. It was found that a sequential approach, wherein psychotherapy precedes meditation, is of overall greater benefit to the client and to both the disciplines of psychotherapy and meditation, than a blended approach. Among the reasons cited for the favoring of a linear progression from psychotherapy to meditation is a respect for the developmental tasks of each individual. In this regard, it was noted that the existential-humanistic therapy tasks of self-identification, emotional contact and expression, ego-development, and increase in self-esteem are necessary before the individual can undertake, in a serious way, the Buddhist meditational tasks of dis-identification for emotional and egoic concerns. In this light, another advantage of the sequential approach is the opportunity provided for the individual to be sufficiently prepared and matured for the discipline of meditation, which is a journey toward higher realms of consciousness not generally obtainable in existential-humanistic psychotherapy. Additionally, it was shown that although Buddhist meditation and existential-humanistic psychotherapy perform corollary functions in the enhancement of individual well-being, the intensification of present awareness, and the lifting of repressedness, there are philosophical differences that are of such sufficient degree that a separation is deemed advisable. It was further seen that a clear distinction between the two disciplines maintains the full integrity and power of each to best accomplish its stated aims. It was noted that meditative practice offers the student specific skills that facilitate the attainment of a still mind, a state of inner harmony, and a transformation and transcendence of the concerns of the pyschotherapeutic level of development.</p>

<p>The union of samatha (tranquility meditation) and vipasyana (insight meditation) is the unique Buddhist path to deliverance. This dissertation explores various schemes of samatha developed in distinct meditation systems, so as to analyze the different degrees of sam adhi which affect the power of insight in eradication of defilements. The nature of dhyana/jhana is explained quite different in the canonical and commentarial materials of Buddhist schools. How a meditator practices mindfulness of breathing is based on how a meditator interprets what the dhyana/jh ana is. This dissertation provides various possible explanations for the diverse dispositions of meditators in meditation practice. In insight meditation, when consciousness acts with skillful mental qualities, one is able to penetrate the true nature of all physical and mental phenomena; in the cycle of rebirth, consciousness links the present existence and the next. The different roles of consciousness in rebirth, and deliverance are investigated. This dissertation is mainly based on the Chinese Canon to examine key issues in meditation practice, revolving around the significance of tranquility meditation and insight meditation.</p>

<p>This study reports on an intervention involving massage, yoga and relaxation delivered to young children with identified emotional and behavioural difficulties, and at risk of exclusion. Children (n = 126) were invited by the head teacher to participate in the Self‐discovery Programme (involving massage, yoga, breath work and relaxation) with parental consent. A total of 107 children aged 8–11 years were given consent by their parents to participate in the study and completed all measures. Children were allocated by the head teacher into the Control (n = 54) or Intervention (n = 53) Groups. The Control Group did not take part in the Self‐discovery Programme. Both groups continued to receive any additional support provided. Results indicate that children in the Intervention Group showed improvements in self‐confidence, social confidence, communication and contribution in the class. Children in the Intervention Group were noted by teachers to use skills learned on the Self‐discovery Programme during the school day.</p>

Drawing on E. Goffman's concepts of face and strategic interaction, the authors define a tease as a playful provocation in which one person comments on something relevant to the target. This approach encompasses the diverse behaviors labeled teasing, clarifies previous ambiguities, differentiates teasing from related practices, and suggests how teasing can lead to hostile or affiliative outcomes. The authors then integrate studies of the content of teasing. Studies indicate that norm violations and conflict prompt teasing. With development, children tease in playful ways, particularly around the ages of 11 and 12 years, and understand and enjoy teasing more. Finally, consistent with hypotheses concerning contextual variation in face concerns, teasing is more frequent and hostile when initiated by high-status and familiar others and men, although gender differences are smaller than assumed. The authors conclude by discussing how teasing varies according to individual differences and culture.

This article discusses how loving-kindness can be used to treat traumatized refugees and minority groups, focusing on examples from our treatment, culturally adapted cognitive-behavioral therapy (CA-CBT). To show how we integrate loving-kindness with other mindfulness interventions and why loving-kindness should be an effective therapeutic technique, we present a typology of mindfulness states and the Nodal Network Model (NNM) of Affect and Affect Regulation. We argue that mindfulness techniques such as loving-kindness are therapeutic for refugees and minority populations because of their potential for increasing emotional flexibility, decreasing rumination, serving as emotional regulation techniques, and forming part of a new adaptive processing mode centered on psychological flexibility. We present a case to illustrate the clinical use of loving-kindness within the context of CA-CBT.

An extensive body of research defines the default-mode network (DMN) to be one of the critical networks of the human brain, playing a pivotal functional role in processes of internal mentation. Alterations in the connectivity of this network as a function of aging have been found, with reductions associated with functional ramifications for the elderly population. This study examined associations between integrity of the DMN and trait levels of mindfulness disposition, defined by our ability to exert attentional and emotional control in the present moment, and, thereby, bring awareness to immediate experiences. Twenty-five older adults participated in the study and underwent a brief functional magnetic resonance imaging session and filled out questionnaires related to their overall health and mindfulness disposition. Mindfulness disposition was associated with greater connectivity of the DMN, specifically, in the dorsal posterior cingulate cortex and the precuneus. Mindfulness disposition, thus, explains variance in the connectivity of one of the more intrinsic networks of the human brain, known to be critical for promoting self-relevant mental explorations and building cognitive and affective control.

Twenty-seven adult survivors of childhood sexual abuse participated in a pilot study comprising an 8-week mindfulness meditation-based stress reduction (MBSR) program and daily home practice of mindfulness skills. Three refresher classes were provided through final follow-up at 24 weeks. Assessments of depressive symptoms, post-traumatic stress disorder (PTSD), anxiety, and mindfulness, were conducted at baseline, 4, 8, and 24 weeks. At 8 weeks, depressive symptoms were reduced by 65%. Statistically significant improvements were observed in all outcomes post-MBSR, with effect sizes above 1.0. Improvements were largely sustained until 24 weeks. Of three PTSD symptom criteria, symptoms of avoidance/numbing were most greatly reduced. Compliance to class attendance and home practice was high, with the intervention proving safe and acceptable to participants. These results warrant further investigation of the MBSR approach in a randomized, controlled trial in this patient population. © 2009 Wiley Periodicals, Inc. J Clin Psychol 66: 1–18, 2010.

Randomized, controlled studies have documented positive physical and psychological effects of writing about traumatic stress. Some of these studies have shown that individual differences play an important role, with participants responding differently to the intervention based on their personal characteristics. In the present expressive writing experiment, the trait of mindfulness was examined as a potential moderator. Seventy-six undergraduates were randomly assigned to either expressive writing (n = 37) or a control group (n = 39). Main effects favoring expressive writing were found, and these were qualified by significant interactions with mindfulness. Specifically, individuals with higher mindfulness scores responded better to expressive writing, experiencing greater physical and psychological benefits than individuals with lower mindfulness scores.

<p>Mindfulness refers to a set of practices as well as the psychological state and trait produced by such practices. The state, trait, and practice of mindfulness may be broadly characterized by a present-oriented, nonjudgmental awareness of cognitions, emotions, sensations, and perceptions without fixation on thoughts of past or future. Research on mindfulness has proliferated over the past decade. Given the explosion of scientific interest in this topic, mindfulness-based therapies are attracting the attention of clinical social workers, who seek to implement these interventions in numerous practice settings. Concomitantly, research on mindfulness is now falling within the scope and purview of social work scholars. In response to the growing interest in mindfulness within academic social work, the present article outlines six conceptual and methodological recommendations for the conduct of future empirical studies on mindfulness. These recommendations have practical importance for advancing mindfulness research within and beyond social work.</p>

Mindfulness practice is an ancient tradition in Eastern philosophy that forms the basis for meditation, and it is increasingly making its way into Western approaches to health care. Although it has been applied to the treatment of many different mental health disorders, it has not been discussed in the context of therapy for sexual problems. In a previous qualitative study of female meditation practitioners who did not have sexual concerns, mindfulness practice was found to be associated with greater sexual response and higher levels of sexual satisfaction. We have recently developed a psychoeducational program for women with sexual arousal disorder subsequent to gynecologic cancer and have included a component of mindfulness training in the intervention. In this paper, we will attempt to provide a rationale for the use of mindfulness in the treatment of women with sexual problems, and will include transcript excerpts from women who participated in our research trial that illustrate how mindfulness was effective in improving their sexuality and quality of life. Although these findings are preliminary, they suggest that mindfulness may have a place in the treatment of sexual concerns.

<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.

OBJECTIVE: Happiness, sadness, and disgust are three emotions that differ in their valence (positive or negative) and associated action tendencies (approach or withdrawal). This study was designed to investigate the neuroanatomical correlates of these discrete emotions.
METHOD: Twelve healthy female subjects were studied. Positron emission tomography and [15O]H2O were used to measure regional brain activity. There were 12 conditions per subject: happiness, sadness, and disgust and three control conditions, each induced by film and recall. Emotion and control tasks were alternated throughout. Condition order was pseudo-randomized and counterbalanced across subjects. Analyses focused on brain activity patterns for each emotion when combining film and recall data.
RESULTS: Happiness, sadness, and disgust were each associated with increases in activity in the thalamus and medial prefrontal cortex (Brodmann's area 9). These three emotions were also associated with activation of anterior and posterior temporal structures, primarily when induced by film. Recalled sadness was associated with increased activation in the anterior insula. Happiness was distinguished from sadness by greater activity in the vicinity of ventral mesial frontal cortex.
CONCLUSIONS: While this study should be considered preliminary, it identifies regions of the brain that participate in happiness, sadness, and disgust, regions that distinguish between positive and negative emotions, and regions that depend on both the elicitor and valence of emotion or their interaction.

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.

Emotions can color people’s attitudes toward unrelated objects in the environment. Existing evidence suggests that such emotional coloring is particularly strong when emotion-triggering information escapes conscious awareness. But is emotional reactivity stronger after nonconscious emotional provocation than after conscious emotional provocation, or does conscious processing specifically change the association between emotional reactivity and evaluations of unrelated objects? In this study, we independently indexed emotional reactivity and coloring as a function of emotional-stimulus awareness to disentangle these accounts. Specifically, we recorded skin-conductance responses to spiders and fearful faces, along with subsequent preferences for novel neutral faces during visually aware and unaware states. Fearful faces increased skin-conductance responses comparably in both stimulus-aware and stimulus-unaware conditions. Yet only when visual awareness was precluded did skin-conductance responses to fearful faces predict decreased likability of neutral faces. These findings suggest a regulatory role for conscious awareness in breaking otherwise automatic associations between physiological reactivity and evaluative emotional responses.
