parapsychology (n.)

"the study of phenomena outside the sphere of orthodox psychology," by 1923, from German para-psychologie; see para- (1) "beside" + psychology. Related: Parapsychological.

Similarly, [Prof. Hans Driesch] includes under "parapsychology" such phenomena as telepathy and clairvoyance, which he regards as mere extensions from ordinary mental phenomena, rather than as fundamentally different processes. He believes that the same orderly process by which unclassified and diverse processes have been systematized,—alchemy becoming chemistry, astrology becoming astronomy,—is at work now,—to make, in place of the mysterious tradition of Occultism, a science which will really be an extension from scientific psychology and biology. ["Journal of the American Society for Psychical Research," April 1923]
