Zenon W. Pylyshyn
Zenon W. Pylyshyn worked across psychology, computer science, and philosophy. He trained in engineering physics, control systems, and experimental psychology. His 1984 book Computation and Cognition developed a computational account of cognitive science. In a 1989 chapter, he examined the meaning and validation of computational explanations. His research also developed Visual Indexing Theory, or FINST, for tracking and referring to objects before their properties are fully encoded. He joined Rutgers in 1991 or 1994 and led cognitive science there during the 1990s.

Earlier career
Several routes into cognition
Pylyshyn trained in engineering physics, control systems, and experimental psychology. He worked at Western Ontario across psychology and computer science. These fields formed the setting for his theoretical work on perception, imagination, and reasoning.

1984–1989
Computation as an explanation
His book Computation and Cognition appeared in 1984. In a chapter published in 1989, he examined the role of computing in cognitive science and how computational models can be validated. He discussed strong equivalence: an account should explain the process that generates behaviour, with empirical support.

Visual indexing
His research includes Visual Indexing Theory, also called FINST. It proposes a mechanism for identifying, tracking, and referring to objects before their properties are encoded. The theory connects visual attention with questions about how cognitive processes refer to the external world.

1990s
A centre for cognitive science
Pylyshyn led Rutgers’ Center for Cognitive Science during the 1990s. He joined Rutgers in 1991 or 1994 and directed the Center until 1997.
