Stuart Appelle (April 3, 1946 – June 27, 2011) was a psychologist and writer, with an interest in topics dealing with anomalous perception, including hypnotic experience, and reports of unidentified flying objects and alien abduction.
Born in 1946, Stuart Appelle began his graduate work in experimental psychology at the Pennsylvania State University.
He introduced the concept of the oblique effect,[1] a construct that is routinely presented in perception textbooks, and broadly cited in the research literature.
[2][3] He is author of more than 40 articles and book chapters, more than 80 entries in the reference text Engineering Data Compendium: Human Perception and Performance, and has presented papers at more than 20 professional meetings.
His work in these areas has been widely published, spanning theoretical problems in the senses, applied work related to blind and developmentally delayed populations, and topics of popular interest such as hypnosis and anomalous experience (e.g. accounts of unidentified flying objects and alien abductions).
