Sensory Neuroscience: Four Laws of Psychophysics

Dr. Jozef Zwislocki holds a Sc.D. degree from the Swiss Federal Institute of Technology and two Dr. h. c. degrees from the Adam Mickiewicz University in Poland and Syracuse University respectively. He is a member of the American and Polish Academies of Sciences and the recipient of numerous research awards. Dr. Zwislocki started his research career as the director of the electroacoustic laboratory in the department of otolaryngology of the University of Basel, Switzerland. From 1951 to 1957, he was a research fellow at Harvard’s Psychoacoustic Laboratory in the department of Experimental Psychology before joining the Faculty of Syracuse University. There, he organized and directed in succession the Bioacoustic Laboratory at the G. D. Hoople Hearing and Speech Center, the Laboratory of Sensory Communication, and the Institute for Sensory Research at the L. C. Smith College of Engineering. He has held the position of a research professor of otolaryngology and communication sciences at the New York State Upstate Medical Center. Though he retired from his directorship at the Institute in 1984, he is currently continuing his research work as both a distinguished professor of neuroscience emeritus at Syracuse University.
