Demonic possession, multiple personalities, spirit possession, self-healing, and exorcism--the psychological study of such phenomena has long been fraught with difficulties. A strong behavioristic approach in the discipline has resulted in a reluctance to examine internal, intangible, inaccessible mental states that are not readily amenable to experimental investigation. In Altered States of Consciousness and Mental Health, a distinguished group of contributors explores these and other phenomena from a cross-cultural perspective. They dispell common misconceptions, clarify terms, and resolve controversies surrounding the relationships between consciousness and psychological well-being. Historical, biological, psychological, and methodological factors are considered from a variety of cultural contexts. In addition, contributors provide fascinating case studies and interviews for each of the phenomena discussed. This ground-breaking study will be of particular interest to cross-cultural psychologists, anthropologists, sociologists, ethnopsychiatrists, and mental health professionals who find themselves coming into increasing contact with these phenomena. "It is an important contribution to cross-cultural understanding of human thinking. . . . I would recommend it strongly to all psychologists and psychiatrists interested in trying to widen the perspectives of their basically Eurocentric disciplines." --British Journal of Psychiatry "An interesting and thought-provoking collection of papers in this emerging field which deserves to become a standard text in the years ahead." --Clinical Psychology Europe "What the book does is to open discussion and pave the way for more and better investigations of the phenomena of altered states of consciousness and their relation to mental health." --New Zealand Journal of Psychology
