Noninvasive recordings of electrical and magnetic fields generated by neuronal activity have helped to characterize the temporal sequencing and mechanisms underlying human cognition. Progress is being made toward the goal of localizing the intracranial loci at which many important electromagnetic signals are generated through the use of new analytic techniques and of scalp recordings of electromagnetic activity in neurological patients and through related work in animals. Such methods alone, however, do not yet have the three-dimensional spatial resolution that is necessary in order to identify the intracranial anatomical structures that are involved in the generation of externally recorded activity and, thus, cannot yet inform us with precision about the anatomical substrates of neural events. In comparison, neuroimaging methods, such as positron emission tomography and functional magnetic resonance imaging, can provide higher spatial resolution information about which brain structures are involved in perceptual, motor, and cognitive processes. However, these imaging methods do not yield much information about the time course of brain activity. One promising approach is to combine electromagnetic recordings and functional neuroimaging in order to gain knowledge about the spatiotemporal organization of human cognition. Here we review how electrophysiology and functional neuroimaging can be combined in the study of attention in normal humans.

<p>As the field of psychology continues to expand and evolve, one fruitful avenue of exploration has been the integration of mindfulness into psychological theory and practice. Mindfulness is defined as the awareness that arises out of intentionally attending in an open and discerning way to whatever is arising in the present moment. Two decades of empirical research have generated considerable evidence supporting the efficacy of mindfulness-based interventions across a wide range of clinical and nonclinical populations, and these interventions have been incorporated into a variety of health care settings. Still, there are many unanswered questions and potential horizons to be investigated. This special issue endeavors to assist in this exploration. It presents a combination of articles concerning aspects of clinical and scientific integration of mindfulness within psychotherapy and psychoeducational settings. This commentary attempts to highlight the main findings of the featured articles as well as elucidate areas for future inquiry. Taken as a whole, the volume supports the importance and viability of the integration of mindfulness into psychology, and offers interesting and meaningful directions for future research. © 2009 Wiley Periodicals, Inc.

The ability to focus one's attention underlies success in many everyday tasks, but voluntary attention cannot be sustained for extended periods of time. In the laboratory, sustained-attention failure is manifest as a decline in perceptual sensitivity with increasing time on task, known as the vigilance decrement. We investigated improvements in sustained attention with training (~ 5 hr/day for 3 months), which consisted of meditation practice that involved sustained selective attention on a chosen stimulus (e.g., the participant's breath). Participants were randomly assigned either to receive training first (n = 30) or to serve as waiting-list controls and receive training second (n = 30). Training produced improvements in visual discrimination that were linked to increases in perceptual sensitivity and improved vigilance during sustained visual attention. Consistent with the resource model of vigilance, these results suggest that perceptual improvements can reduce the resource demand imposed by target discrimination and thus make it easier to sustain voluntary attention.

We discuss preliminary findings from a study that investigated the effectiveness of a Holistic Arts-Based Group Program (HAP) for the development of resilience in children in need. The HAP teaches mindfulness using arts-based methods, and aims to teach children how to understand their feelings and develop their strengths. We assessed the effectiveness of the HAP by using comparison and control groups, and standardized measures. We hypothesized that children who participated in the HAP would have better scores on resilience and self-concept compared with children who took part in an Arts and Crafts group (the comparison group), and children who were waiting to attend the HAP (the control group). A total of 36 children participated in the study; 20 boys aged 8–13 years and 16 girls aged 8–14 years. A mixed-designed MANOVA was conducted using scores from 21 participants. We found evidence that the HAP program was beneficial for the children in that they self-reported lower emotional reactivity (a resilience measure) post-intervention. No changes were noted for perceptions of self-concept. Consideration should be given to how we can attend to young people’s needs in relevant ways as resilience is a condition of a community’s ability to provide resources as much as it is part of an individual’s capacity for growth. Programs such as the HAP can engage children in a creative and meaningful process that is enjoyable and strengths-based.

We investigated whether mindfulness training (MT) influences information processing in a working memory task with complex visual stimuli. Participants were tested before (T1) and after (T2) participation in an intensive one-month MT retreat, and their performance was compared with that of an age- and education-matched control group. Accuracy did not differ across groups at either time point. Response times were faster and significantly less variable in the MT versus the control group at T2. Since these results could be due to changes in mnemonic processes, speed-accuracy trade-off, or nondecisional factors (e.g., motor execution), we used a mathematical modeling approach to disentangle these factors. The EZ-diffusion model (Wagenmakers, van der Maas, & Grasman, Psychonomic Bulletin & Review 14:(1), 3-22, 2007) suggested that MT leads to improved information quality and reduced response conservativeness, with no changes in nondecisional factors. The noisy exemplar model further suggested that the increase in information quality reflected a decrease in encoding noise and not an increase in forgetting. Thus, mathematical modeling may help clarify the mechanisms by which MT produces salutary effects on performance.

To better understand the neurobiological mechanisms by which mindfulness-based practices function in a psychotherapeutic context, this article details the definition, techniques, and purposes ascribed to mindfulness training as described by its Buddhist tradition of origin and by contemporary neurocognitive models. Included is theory of how maladaptive mental processes become habitual and automatic, both from the Buddhist and Western psychological perspective. Specific noting and labeling techniques in open monitoring meditation, described in the Theravada and Western contemporary traditions, are highlighted as providing unique access to multiple modalities of awareness. Potential explicit and implicit mechanisms are discussed by which such techniques can contribute to transforming maladaptive habits of mind and perceptual and cognitive biases, improving efficiency, facilitating integration, and providing the flexibility to switch between systems of self-processing. Finally, a model is provided to describe the timing by which noting and labeling practices have the potential to influence different stages of low- and high-level neural processing. Hypotheses are proposed concerning both levels of processing in relation to the extent of practice. Implications for the nature of subjective experience and self-processing as it relates to one's habits of mind, behavior, and relation to the external world, are also described.

Those with high baseline stress levels are more likely to develop mild cognitive impairment (MCI) and Alzheimer's Disease (AD). While meditation may reduce stress and alter the hippocampus and default mode network (DMN), little is known about its impact in these populations. Our objective was to conduct a "proof of concept" trial to determine whether Mindfulness Based Stress Reduction (MBSR) would improve DMN connectivity and reduce hippocampal atrophy among adults with MCI. 14 adults with MCI were randomized to MBSR vs. usual care and underwent resting state fMRI at baseline and follow-up. Seed based functional connectivity was applied using posterior cingulate cortex as seed. Brain morphometry analyses were performed using FreeSurfer. The results showed that after the intervention, MBSR participants had increased functional connectivity between the posterior cingulate cortex and bilateral medial prefrontal cortex and left hippocampus compared to controls. In addition, MBSR participants had trends of less bilateral hippocampal volume atrophy than control participants. These preliminary results indicate that in adults with MCI, MBSR may have a positive impact on the regions of the brain most related to MCI and AD. Further research with larger sample sizes and longer-follow-up are needed to further investigate the results from this pilot study.

In this article the author examines the use of meditation as an aid to conventional medicine, examines the increased research on the subject, and offers a critique of Mindfulness-Based Stress Reduction (MBSR), the therapeutic meditation method developed by molecular biologist Jon Kabat-Zinn. A number of topics are addressed including Kabat-Zinn's perception of MBSR as Buddhist meditation without a religious element, the moral framework of yoga and meditation, and the lack of interaction and community in the practice of MBSR.

This study investigated the link between meditation, self-reported mindfulness and cognitive flexibility as well as other attentional functions. It compared a group of meditators experienced in mindfulness meditation with a meditation-naïve control group on measures of Stroop interference and the “d2-concentration and endurance test”. Overall the results suggest that attentional performance and cognitive flexibility are positively related to meditation practice and levels of mindfulness. Meditators performed significantly better than non-meditators on all measures of attention. Furthermore, self-reported mindfulness was higher in meditators than non-meditators and correlations with all attention measures were of moderate to high strength. This pattern of results suggests that mindfulness is intimately linked to improvements of attentional functions and cognitive flexibility. The relevance of these findings for mental balance and well-being are discussed.

<p>Meditative dialogue is a mindfulness method through which families and their therapists are able to access the present moment and develop acceptance, non-judgmental attitudes and attunement with one another and with the music that is always present in their lives. This process can be used to deepen empathic connections, tap into creative forces and loosen and encourage embodied and flexible interactions that alter patterns and cultivate openness to possibility and to change.</p>

<p>Studies suggest that young children are quite limited in their knowledge about cognitive phenomena—or in their metacognition—and do relatively little monitoring of their own memory, comprehension, and other cognitive enterprises. Metacognitive knowledge is one's stored knowledge or beliefs about oneself and others as cognitive agents, about tasks, about actions or strategies, and about how all these interact to affect the outcomes of any sort of intellectual enterprise. Metacognitive experiences are conscious cognitive or affective experiences that occur during the enterprise and concern any aspect of it—often, how well it is going. Research is needed to describe and explain spontaneous developmental acquisitions in this area and find effective ways of teaching metacognitive knowledge and cognitive monitoring skills. (9 ref)</p>

<p>Mindfulness-based approaches are increasingly employed as interventions for treating a variety of psychological, psychiatric and physical problems. Such approaches include ancient Buddhist mindfulness meditations such as Vipassana and Zen meditations, modern group-based standardized meditations, such as mindfulness-based stress reduction and mindfulness-based cognitive therapy, and further psychological interventions, such as dialectical behavioral therapy and acceptance and commitment therapy. We review commonalities and differences of these interventions regarding philosophical background, main techniques, aims, outcomes, neurobiology and psychological mechanisms. In sum, the currently applied mindfulness-based interventions show large differences in the way mindfulness is conceptualized and practiced. The decision to consider such practices as unitary or as distinct phenomena will probably influence the direction of future research. © 2011 Wiley Periodicals, Inc. J Clin Psychol 67:1-21, 2011.</p>

Interest in applications of mindfulness-based approaches with adults has grown rapidly in recent times, and there is an expanding research base that suggests these are efficacious approaches to promoting psychological health and well-being. Interest has spread to applications of mindfulness-based approaches with children and adolescents, yet the research is still in its infancy. I aim to provide a preliminary review of the current research base of mindfulness-based approaches with children and adolescents, focusing on MBSR/MBCT models, which place the regular practice of mindfulness meditation at the core of the intervention. Overall, the current research base provides support for the feasibility of mindfulness-based interventions with children and adolescents, however there is no generalized empirical evidence of the efficacy of these interventions. For the field to advance, I suggest that research needs to shift away from feasibility studies towards large, well-designed studies with robust methodologies, and adopt standardized formats for interventions, allowing for replication and comparison studies, to develop a firm research evidence base.
