international professional society in parapsychology. The aim of the organization, as stated in its Constitution, became "to advance parapsychology as a science, to disseminate knowledge of the field, and to integrate the findings with those of other branches of science". In 1969, under the direction of anthropologist Margaret Mead, the Parapsychological Association became affiliated with the American Association for the Advancement of Science (AAAS), the largest general scientific society in the world. In 1979, physicist John A. Wheeler said that parapsychology is pseudoscientific, and that the affiliation of the PA to the AAAS needed to be reconsidered. His challenge to parapsychology's AAAS affiliation was unsuccessful. Today, the PA consists of about three hundred full, associate, and affiliated members worldwide. Stargate Project Beginning in the early 1950s, the CIA started extensive research into behavioral engineering. The findings from these experiments led to the formation of the Stargate Project, which handled ESP research for the U.S. federal government. The Stargate Project was terminated in 1995 with the conclusion that it was never useful in any intelligence operation. The information was vague and included a lot of irrelevant and erroneous data. There was also reason to suspect that the research managers had adjusted their project reports to fit the known background cues. 1970s and 1980s The affiliation of the Parapsychological Association (PA) with the American Association for the Advancement of Science, along with a general openness to psychic and occult phenomena in the 1970s, led to a decade of increased parapsychological research. During this period, other related organizations were also formed, including the Academy of Parapsychology and Medicine (1970), the Institute of Parascience (1971), the Academy of Religion and Psychical Research, the Institute of Noetic Sciences (1973), the International Kirlian Research Association (1975), and the Princeton Engineering Anomalies Research Laboratory (1979). Parapsychological work was also conducted at the Stanford Research Institute (SRI) during this time. 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.
