Meditation research has grown substantially over the last 30 years, emerging from contemplative and spiritual traditions. This chapter reviews meditation classifications, which remain varied and subjective, and suggests broader multidimensional models for future improvement. Phenomenological studies, though few, are increasing and link subjective experience to neurophysiology. EEG oscillatory studies are inconclusive due to heterogeneity in meditation styles and practitioners. Neuroimaging reveals common patterns during meditation and in long-term practitioners, reflecting general similarities, but most patterns differ across traditions. Research on attention and emotion regulation mechanisms is discussed. Evidence shows positive benefits for stress reduction, anxiety, depression, and pain in some clinical populations, though methodological and conceptual issues remain.

A survey of 1120 meditators found that most report having had anomalous and extraordinary experiences during meditation, such as mystical, transpersonal, or difficult phenomena. While meditation research has largely focused on clinical effectiveness and neural correlates, these less-studied experiences may be crucial for psychological and spiritual development, act as mediators of meditation's benefits, or be important outcomes themselves. A task force of researchers and teachers developed recommendations to expand research into these areas, which represent largely uncharted scientific terrain suitable for rigorous investigation.

Consciousness remains a profound mystery. Mainstream neuroscience assumes it arises solely from brain neurons, but the origin of subjective experience (qualia) is unexplained. David Chalmers called this the 'hard problem.' This review argues the hard problem may stem from flawed materialist assumptions. It examines phenomena suggesting consciousness can extend beyond the brain and body in space and time, called non-local properties. These effects vaguely resemble quantum entanglement, but mechanisms are highly speculative. The authors suggest post-materialistic models may be needed to resolve the conceptual impasse.

In a controlled experiment with 13 healthy adult trance channels, voice recordings showed increased arousal and power differences in specific frequency bins when participants read a story in a channeling state compared to a no-channeling state. However, electroencephalography, electrocardiography, galvanic skin response, and respiration measures did not differ significantly between the two states, despite participants reporting distinct subjective experiences. The findings suggest that while voice parameters may reflect the channeling experience, other physiological measures do not capture it. Future research should explore alternative measures such as EEG connectivity, fMRI, and biomarkers.

People who feel more interconnected with others and nature tend to report better well-being, including more positive emotions and compassion, and less pain and sleep disturbance. In a study of adults attending personal development workshops, measures of interconnectedness were positively correlated with well-being and positive affect, and negatively correlated with sleep disturbance and pain. Extended perception tasks showed no link to interconnectedness or well-being. After workshops, participants reported improved well-being, interconnectedness, positive emotion, and compassion, and reduced sleep disturbances, negative emotion, and pain. Workshop formats involving lecture, small groups, pairs, and discussion predicted well-being improvements, as did content including meditation and technology tools. Meditation was the most consistent predictor of positive well-being changes. Conscientiousness was the only individual characteristic that predicted changes, but its effects were mixed.
