Stimulated by a recent meeting between Western psychologists and the Dalai Lama on the topic of destructive emotions, we report on two issues: the achievement of enduring happiness, what Tibetan Buddhists call sukha, and the nature of afflictive and nonafflictive emotional states and traits. A Buddhist perspective on these issues is presented, along with discussion of the challenges the Buddhist view raises for empirical research and theory.

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.

The capacity to focus one's attention for an extended period of time can be increased through training in contemplative practices. However, the cognitive processes engaged during meditation that support trait changes in cognition are not well characterized. We conducted a longitudinal wait-list controlled study of intensive meditation training. Retreat participants practiced focused attention (FA) meditation techniques for three months during an initial retreat. Wait-list participants later undertook formally identical training during a second retreat. Dense-array scalp-recorded electroencephalogram (EEG) data were collected during 6 min of mindfulness of breathing meditation at three assessment points during each retreat. Second-order blind source separation, along with a novel semi-automatic artifact removal tool (SMART), was used for data preprocessing. We observed replicable reductions in meditative state-related beta-band power bilaterally over anteriocentral and posterior scalp regions. In addition, individual alpha frequency (IAF) decreased across both retreats and in direct relation to the amount of meditative practice. These findings provide evidence for replicable longitudinal changes in brain oscillatory activity during meditation and increase our understanding of the cortical processes engaged during meditation that may support long-term improvements in cognition.

This book takes a bold new look at ways of exploring the nature, origins, and potentials of consciousness within the context of science and religion. It draws careful distinctions between four elements of the scientific tradition: science itself, scientific realism, scientific materialism, and scientism. Arguing that the metaphysical doctrine of scientific materialism has taken on the role of ersatz-religion for its adherents, it traces its development from its Greek and Judeo-Christian origins, focusing on the interrelation between the Protestant Reformation and the Scientific Revolution. It also looks at scientists' long term resistance to the firsthand study of consciousness and details the ways in which subjectivity has been deemed taboo within the scientific community. In conclusion, the book draws on William James's idea for a “science of religion” that would study the nature of religious and, in particular, contemplative experience.
