An Empirical Analysis for Social Scientists by Imants Baruss: Book review: “In Alterations of Consciousness, ImantsBaruss, a psychology professor, examines consciousness, an intriguing and controversial subject in cognitive science. He discusses eight different states of consciousness: wakefulness, sleep, dreaming, hypnosis, trance, chemically induced alterations, transcendent states, and experiences associated with death. His approach is multifaceted, and it features three perspectives (physiological, cognitive and experiential) as frameworks for understanding the study of consciousness. Even though the narrative is slanted towards the experiential viewpoint, Baruss manages to organize these different perspectives into an appealing mosaic of research findings and related commentaries…” mentalhelp.net
