Metafi zyczna koncepcja nagiego substratu a badania nad percepcją wzrokową (na przykładzie eksperymentu MOT w interpretacji Zenona Pylyshyna)

The Metaphysical Bare Substratum Theory and Investigations Concerning Visual Perception (Based on MOT Experiment in the Zenon Pylyshyn's Interpretation)Th e paper juxtaposes the metaphysical theory of bare substrate (which is a theory of an individual object) with the results of research on visual perception – the MOT experiment and the FINST concept, by Zenon Pylyshyn, related to the experiment. Th e author points out the similarities between the theory of bare substrate and the FINST idea and then presents to what extent the MOT result might be an argument for the adequacy of the theory of bare substrate as a theory of individual object. Moreover, taking the above concepts as an example, it will be shown how metaphysical theories can be justifi ed by results of empirical research (in order to do this, some falsifi able hypotheses will be inferred from the theory of bare substrate) and how metaphysical theories can be used to interpret test results
