Investigation of Vicarious Actions in the Context of Intellectual Problems
For many years the simulation hypothesis (Leont’ev, 1959) has been developed and confirmed mainly through investigations of image formation. This hypothesis has frequently been questioned, for it is impossible to determine isomorphism between the motor side of perceptual systems and the properties of the perceptual procedures in fully developed processes of perception.* However, this fact can be explained without any contribution to the praxeological interpretation of perception processes Any living system, at a stage of development other than zero, possesses a developed alphabet of images or operative units of perception. Whereas in the phase of construction of the image of an object, simulation of the properties of the stimulus by the perceptual systems takes place, in the phase of identification of or operation with the resulting image the characteristics and direction of the simulation process are substantially changed. This was clearly observed by A. V. Zaporozhets: “in investigations by my colleagues and myself, regular changes could be seen in the simulating function of perceptual action throughout infancy and at preschool age, and at the same time, they provided a more detailed explanation of some of the special features of the complex and controvertial process of simulation.
