The effect of meditation on pain perception was investigated. Zen meditators and controls were instructed to attend, in different ways, to painful and non-painful thermal stimuli. Conditions included: a) baseline, b) concentration: attend exclusively to the left calf, c) mindfulness: attend to the left calf and observe, moment to moment, in a non-judgmental manner. Meditators …

Most meditation traditions integrate attention to the internal state of the body into the practice of meditation, and teach that a central effect of the meditative practice is increased awareness of the body. To test whether meditators have increased body awareness we examined the performance of two groups of experienced meditators compared to one group …
Posttraumatic stress disorder (PTSD) is seriously debilitating and common, with 5-10% incidence in general population and over 30% in combat veterans. PTSD symptoms include emotional dysregulation, intrusive, distressing trauma memories, nightmares, and ‘flashbacks’. Our laboratory has reported exaggerated a.) first-person emotional b.) psychophysiological and c.) neuroendocrine responses to trauma recall in combat PTSD patients, and …
The objective of present study is to evaluate the effectiveness of a primary prevention program—“Mindfulness Education” (ME)—a classroom-based program designed to foster children’s mindful awareness, psychological well-being, and social-emotional competencies. This study will provide an examination of multiple areas of functioning—cognitive, affective, behavioural, interpersonal and physiological through the collection of data from multiple-informants (self-reports, peer …
We are presently undertaking a series of psychophysical pilot studies, recording extensive data from a small number of individuals. Using breath as the object of meditation, we are searching for EEG signals (possibly in the gamma-frequency band) that correlate with attentional quality. In response to a cue, subjects indicate by button press their subjective level …

We hypothesized that 8-week mindfulness meditative training (MMT) would significantly decrease 1) cognitive/emotional biases associated with perception of pain and general dysfunction in fibromyalgia (FM) and 2) the magnitudes of various symptoms in FM patients. Changes were documented in self-reported measures of primary and secondary symptoms, mindfulness, cognitive/emotional biases associated with the experience of pain …
Previous studies have indicated that mindfulness and other forms of meditation training are associated with improvements in sleep quality. However, none of these studies used objective polysomnographic sleep recordings. The aim of this study was to examine whether mindfulness meditation was associated with improvements in objectively measured sleep, according to polysomnography (PSG), and to relate …
Interest in investigating the neural correlates of different meditation practices is increasing within the neuroscience community. In particular, shamatha practice, which strengthens the ability of a practitioner to sustain a concentrated, single-pointed focus of attention, is a natural focus for attention researchers within cognitive neuroscience. However, studies of the medium- and long-term effects of shamatha …

During concentration tasks, spontaneous attention shifts occurs towards self-centered matters. Little is known about the brain oscillatory activity underlying these mental phenomena. We recorded 128-channels electroencephalographic activity from 12 subjects performing a breath-counting task. Subjects were instructed to press a button whenever, based on their introspective experience, they realized their attention had drifted away from …
There is a growing interest in the application of mindfulness techniques for modulating one’s relationship to ongoing mental experience. However, there is need for detailed empirical investigations using experimental paradigms to address (a) whether mindfulness training works, (b) how it affects emotional reactivity and regulation, (c) what neural systems are modulated by training in mindfulness …
