Proceeding from the idea of polyfunctionality of the immediate sensual reflection and from some ideas concerning the functional scope of movement perception the authors analyze perception of objects' movement and speed without any physical concept of motion as the logical basis of their analysis. For them perception of movement is a polyfunctional process centered around the process of form-formation which assures the opportunity for immediate-sensual detection of both the speed and the form of a moving object. The experimentally obtained data are used to set forth a hypothesis that an object's perceived speed is a function of the time needed for reconstruction of its form.
