John Garcia (June 12, 1917 – October 12, 2012[1]) was an American psychologist, most known for his research on conditioned taste aversion. Garcia studied at the University of California-Berkeley, where he received his A.B., M.A., and Ph.D. degrees in 1955 in his late forties. At his death, he was professor emeritus at University of California, Los Angeles. Previously, he was an assistant professor at California State University at Long Beach, a lecturer in the Department of Surgery at Harvard Medical School, professor and chairman of the Psychology Department at the State University of New York at Stony Brook, and Professor of Psychology at the University of Utah. A Review of General Psychology survey, published in 2002, ranked Garcia as the 88th most cited psychologist of the 20th century, tied with James J. Gibson, David Rumelhart, Louis Leon Thurstone, Margaret Floy Washburn, and Robert S. Woodworth.[2]
