Waddington John B. This is because cognition is clearly "information processing. Pylyshyn argues that cognitive processes can be understood as formal operations carried out on symbol structures. This flawed idea goes back to a few years before the first digital computers were actually built ENIAC in In Warren McCulloch and Walter Pittsthe first a neurophysiologist and symbolic logician and the second a self-taught expert in the symbolic logic of Bertrand Russell and Rudolf Carnapthought that the synapses between neurons could be binary logical gates that would support symbolic logic in the brain.

For the past fifteen years, Pylyshyn's personal research has dealt with two general areas. One is the theoretical analysis of the nature of the human cognitive system that enables humans to perceive the world, as well as to reason and imagine. This has led to a number of theoretical investigations of the "architecture of the mind". On the experimental side Pylyshyn has been concerned with exploring his Visual Indexing Theory sometimes called the FINST theorydealing with how human visual attention is allocated and how humans cognize objects and space.

This theory hypothesizes a preconceptual mechanism by which objects in a visual scene can be individuated, tracked, and directly or demonstratively referred to by cognitive processes prior to their properties being encoded. Over a dozen papers have been published on this theory and its experimental investigation, as well as its implications for understanding how vision is connected with the world, making perceptual-motor coordination possible.

This theory hypothesizes a preconceptual mechanism by which objects in a visual scene can be individuated, tracked, and directly or demonstratively referred to by cognitive processes prior to their properties being encoded. Over a dozen papers have been published on this theory and its experimental investigation, as well as its implications for understanding how vision is connected with the world, making perceptual-motor coordination possible.

The theory has implications for philosophical issues concerning the semantics of visual perception as well as practical applications for the design of human-computer interfaces. Skip to main content.
