Abstract The equipment is to test psychologically drivers of all kinds of motor vehicles. With this equipment one can test the competence in evaluating speed, which is based on the psychophysiological attribute, that is, the ability of perceiving motion. Inside the casing, are located the electric system of the equipment and the driving mechanisms of the two disks. The left disk rotates with a constant rotational speed and has three constant rates of rotational speed. The right disk has three rates of variable speed, regulated automatically within certain limits by the tested person. The test consists in the tested person trying to regulate the rotation speed of the right disk in order to obtain the same rotation speed as on the left disk, within a specified period of time. The result of the test consists in measuring the differences in rotation speeds of both disks, as recorded automatically on the scale of the tachograph.
Apparatus for testing the capacity of perceiving motion which comprises a pair of rotatable discs with identical indicia applied thereto, said discs being located where they can be viewed simultaneously by a person being tested, separate electric motors each driving a separate said disc, electric circuit means supplying electric current to each said motor, one of said discs being driven by its corresponding electric motor at a predetermined constant rotational speed, automatic control means continually changing the rotational speed of the other of said discs in a predetermined manner whereby the rotational speed of said other disc varies within a range from lower than that of the one said disc to higher than that of the one said disc, rotational speed indication means indicating the rotational speed of said other disc, and selector means for the person being tested to signal when in his judgment the rotational speeds of said pair of discs are the same.
