This is a thoroughly updated and revised edition of our highly acclaimed university textbook on the science of parapsychology. The objective of this book is to provide an introductory survey of parapsychologists' efforts to explore the authenticity and bases of anomalous, apparently paranormal phenomena. Dr. Irwin outlines the origins of parapsychological research and critically reviews investigations of extrasensory perception, psychokinesis, poltergeist phenomena, near-death and out-of-body experiences, and the evaluation of parapsychology as a scientific enterprise.
