About the author
Gertrude Schmeidler (1912-2009) was an American psychologist known for her research on extrasensory perception, most notably her work identifying the so-called sheep-goat effect, the finding that people who believe ESP is possible tend to score differently on ESP tests than those who do not. She taught for decades at the City College of New York and was an active figure in the Parapsychological Association. Her edited volume Extrasensory Perception, reissued by Routledge, gathers research addressing why ESP ability, if real, varies so much between individuals and even between test sessions with the same person, focusing on the psychological conditions that appear to affect performance. The book reflects Schmeidler's broader approach to parapsychology, treating claimed psychic ability as a subject for careful experimental psychology rather than either outright dismissal or uncritical acceptance. It remains a reference point in the academic literature on ESP research methodology.
