Robert Nosofsky

Robert Mark Nosofsky (born c. 1956) is an American psychologist. He is a professor in the department of psychological and brain sciences at Indiana University Bloomington, who is known for his exemplar theory. His research interest are categorization, recognition memory, math modeling, combining formal modeling and FMRI Studies. His research is in the development and testing of formal mathematical models of perceptual category learning and representation.

Life and education
Nosofsky was born in U.S.A. He graduated with a B.A. in psychology and mathematics at Binghamton University in 1978 and a Ph.D. in psychology at Harvard University in 1984.

Exemplar theory
The exemplar theory, which was proposed by Robert Nosofsky is different from the prototype theory, proposed by Eleanor Rosch, and the demarcator theory, proposed by Taraneh Javanbakht. According to the exemplar theory, the human cognition of concept categories is based on the use of exemplars of concepts. The exemplar theory explains how the human beings learn and use these concept categories.

Awards and honors
Nosofsky received the first New Investigator Research Award of the Society of Mathematical Psychology (1987), APA's Distinguished Scientific Award for Early Career Contribution to Psychology (1993), and the Troland Award from the National Academy of Sciences (1995). He was elected to the Society of Experimental Psychologists, the leading honorary society in the field, in 1998. In January, he accepted the editorship of the Psychonomic Bulletin & Review.
