The PERCRO – Perceptual Robotics Laboratory, from Scuola Superiore Sant’Anna, Pisa, is presenting a series of lectures by Alan Wallace on June 17th, 18th and 19th, 2008.

Dr. Wallace, a scholar and practitioner of Buddhism since 1970, has taught Buddhist theory and meditation worldwide since 1976. Having devoted fourteen years to training as a Tibetan Buddhist monk, ordained by H. H. the Dalai Lama, he went on to earn an undergraduate degree in physics and the philosophy of science at Amherst College and a doctorate in religious studies at Stanford. With his unique background, Alan Wallace brings deep experience and applied skills to the challenge of integrating traditional Indo-Tibetan Buddhism with the modern world, continually seeking innovative ways to integrate Buddhist contemplative practices with Western science to advance the study of the mind.

The three lectures will deal with the results of the collaboration between psychologists and neuroscientists that took physiological and psychological measurements of people involved in an intensive mediation retreat; the convergences between Buddhism and Physics and the Question of Free Will.

Spatial memories of virtual environments: how egocentric experience, intrinsic structure, and extrinsic structure interact.

Psychon Bull Rev. 2008 Apr;15(2):322-7

Authors: Kelly JW, McNamara TP

Previous research has uncovered three primary cues that influence spatial memory organization:egocentric experience, intrinsic structure (object defined), and extrinsic structure (environment defined). In the present experiments, we assessed the relative importance of these cues when all three were available during learning. Participants learned layouts from two perspectives in immersive virtual reality. In Experiment 1, axes defined by intrinsic and extrinsic structures were in conflict, and learning occurred from two perspectives, each aligned with either the intrinsic or the extrinsic structure. Spatial memories were organized around a reference direction selected from the first perspective, regardless of its alignment with intrinsic or extrinsic structures. In Experiment 2, axes defined by intrinsic and extrinsic structures were congruent, and spatial memories were organized around reference axes defined by those congruent structures, rather than by the initially experienced view. The findings are discussed in the context of spatial memory theory as it relates to real and virtual environments.

Combining Mindfulness Meditation with Cognitive-Behavior Therapy for Insomnia: A Treatment-Development Study.

Behav Ther. 2008 Jun;39(2):171-182

Authors: Ong JC, Shapiro SL, Manber R

This treatment-development study is a Stage I evaluation of an intervention that combines mindfulness meditation with cognitive-behavior therapy for insomnia (CBT-I). Thirty adults who met research diagnostic criteria for Psychophysiological Insomnia (Edinger et al., 2004) participated in a 6-week, multi-component group intervention using mindfulness meditation, sleep restriction, stimulus control, sleep education, and sleep hygiene. Sleep diaries and self-reported pre-sleep arousal were assessed weekly while secondary measures of insomnia severity, arousal, mindfulness skills, and daytime functioning were assessed at pre-treatment and post-treatment. Data collected on recruitment, retention, compliance, and satisfaction indicate that the treatment protocol is feasible to deliver and is acceptable for individuals seeking treatment for insomnia. The overall patterns of change with treatment demonstrated statistically and clinically significant improvements in several nighttime symptoms of insomnia as well as statistically significant reductions in pre-sleep arousal, sleep effort, and dysfunctional sleep-related cognitions. In addition, a significant correlation was found between the number of meditation sessions and changes on a trait measure of arousal. Together, the findings indicate that mindfulness meditation can be combined with CBT-I and this integrated intervention is associated with reductions in both sleep and sleep-related arousal. Further testing of this intervention using randomized controlled trials is warranted to evaluate the efficacy of the intervention for this population and the specific effects of each component on sleep and both psychological and physiological arousal.
