Identification of images as a series of gradual transformations of geometrical figures

In the course of psychophysiological experiments with a tachistiscopic presentation of geometrical figures as transformations from a square into a triangle, the subjects worked out a distance scale for optical mouse movement depending on the degree of similarity between the presented figure and a square. This curve appears as a gradual decrease in the distance during the figure's transformation from a square into a triangle. Significant variation in the shape of the curve was revealed upon exclusion of one of the images of the alphabet. The results are discussed in the context of the lateral inhibition phenomena and compared with the data of the theory of identification. © 2011 Pleiades Publishing, Ltd.
