The scope of parapsychology expanded during these years. Psychiatrist Ian Stevenson conducted much of his research into reincarnation during the 1970s, and the second edition of his "Twenty Cases Suggestive of Reincarnation" was published in 1974. Psychologist Thelma Moss devoted time to the study of Kirlian photography at UCLA's parapsychology laboratory. The influx of spiritual teachers from Asia, and their claims of abilities produced by meditation, led to research on altered states of consciousness. American Society for Psychical Research Director of Research, Karlis Osis, conducted experiments in out of body experiences. Physicist Russell Targ coined the term remote viewing for use in some of his work at SRI in 1974.
