Parapsychology is the branch of psychology that deals with paranormal phenomena as observed by extrasensory perception. The task of parapsychology is to expand the known methods and principles of psychology to include an explanation of paranormal phenomena. From 1927 to 1965 J.B. Rhine at Duke University, North Carolina, directed a psychological research laboratory that attempted systematically to study these phenomena. The main criticism of this work is that experiments pointing to the existence of paranormal phenomena could not be replicated outside of Rhine's lab, but see replication.
