Dr. Paratt is a frequent contributor of articles dealing with psychology and biology to such magazines as Journal of Comparative Psychology, Journal of Experimental Biology, Science, and American Naturalist, as author and as co-author with T. L. McCulloch, R. H. Thouless (q.v.) and other. Although he interested in the field of parapsychology as a whole, he has specialized in quantitative experiment in extrasensory perception. His investigations have included the Pearce-Pratt series (with Hubert E. Pearce, Jr.) and the Pratt-Woodruff series (with J. L. Woodruff, q.v.), primarily concerned with attempts to throw light on the factors influencing ESP as a reponse process, and approached from the view of subjec-centered factors, experimenter-centered factors, and those related to the structure of the test as a psychological situation.
His more than 50 publications in the field of parapsychology include the books Handbook for Testing Extrasensory Perception (with C.E. Stuart, q.v.; 1937); Extrasensory Perception After Sixty Years (with J. B. Rhine, Stuart, B. M. Smith, J. A. Greenwood, qq.v.; 1940); Parapsychology: Frontier Science of the Mind (with J. B. Rhine, 1957); the articles (in Journal of Parapsychology): "Size of Stimulus Symbols in Extrasensory Perception" (with Woodruff; Vol. 3, 1939); "Appraising Verbal Test Material in Parapsychology" (with W. R. Birge, Vol. 12, 1948); "The Homing Problem in Pigeons" (Vol. 17, 1953); "A Review of the Pearce-Pratt Distance Series of ESP Test" (with Rhine; Vol. 18, 1954); and in the Ciba Foundation Symposium on Extrasensory Perception (1956), "Testing for an ESP Factor in Pigeon Homing."
