parapsychology, study of mental phenomena not explainable by accepted principles of science. The organized, scientific investigation of paranormal phenomena began with the foundation (1882) of the Society for Psychical Research in London. Such early efforts attempted to dissociate psychical phenomena from spiritualism and superstition, and particularly to investigate mediums and their claims of evoking spirits or apparitions. The society also studied automatic writing, levitation, and ectoplasmic and poltergeist activities. One of its principal founders, Frederic William Henry Myers, summed up the society's early efforts in Human Personality and Its Survival of Bodily Death (1903). An American Society for Psychical Research was also founded, with James Hervey Hyslop as its leading spokesman. Considerable experimentation has been conducted, perhaps the best-known being that of Joseph Banks Rhine at Duke. The Foundation for Research on the Nature of Man, created in the early 1960s, has since replaced the Duke program. In Great Britain the work of Whately Carington and Samuel George Soal paralleled that of Rhine. The great majority of parapsychological studies have focused on the area called extrasensory perception (ESP), which includes telepathy, clairvoyance, and precognition. The popular press often reports stories that are parapsychological in nature. Many scientists criticize the claims made by parapsychologists, arguing in particular that there can be no proof of such phenomena.
