Description

The invention relates to a medicamental technique and is intended for psychophysiological studies.

The purpose of the invention is to create the possibility of quantitative assessment of human prognostic abilities.

FIG. 1 shows a block diagram of the proposed device; Fig. 2 is an electrical circuit diagram of the device; in fig. 3 - kinematic diagram of the device; in fig. 4 shows the optical layout of the device.

The device contains a switching unit 1, - illuminator 2, interchangeable plates 3 with standard drawings, screen 4, electric stopwatch 5, first electric motor 6, first screw pair 7, second electric motor 8, second screw pair 9, probe 10, made in the form of a string on a frame , aiTop-ku 11, spring contact 12 of pencil 13 and spring contact 14.

The switching unit 1 contains the first 15, second 16 and third 17 electromagnetic relays with their contacts, the Start button 18 and the Reset button 19. The relay coils 15 - 17 are closed on. body through the contacts of the button 19 Reset. The winding of the first relay 15 is electrically connected to a power source (not shown). Winding the second turnip. 16 is electrically connected to the power source via spring contact 14, and the winding of the third relay 17 is via contact 20, the first motor 6, the second electric motor .8 and the illuminator 2 are electrically connected to the power source through contact 21. The first motor 6 is electrically connected the power bus through contacts 22, and the second electric motor 8 through contacts 23. Electrosecond meter 5 is connected to the power circuit via contacts 24 and 25.

The kinematic part of the proposed device (FIG. 3) includes the first screw pair 7, the kinematically connecting shaft of the first electric motor 6 with the probe 10, and the second screw pair 9, the kinematically connecting shaft of the second electric motor 8 with the curtain 11, kinematically associated with the pr. provides the ability to change the speed of rotation of the motor shaft by changing the resistance in the power supply circuit of the electric motors with a positive contact 14, as well as a pencil 13 with a spring contact 12, kine-55 by means of a rheostat, At the same time, the speed of movement of the shutter and probe is matically related to the screen. The optical part of the proposed device is measured by means of a large-scale device (Fig. 4) and contains grid lights on the screen 4 extrapol error

The tele /, made in the form of an overhead projector and optically coupled to the screen 4 via interchangeable plates 3 with standard patterns. The shutter 11 is optically coupled to the screen 4, the probe 10 is optically coupled to the screen 4 via interchangeable plates 3 with standard patterns.

In Figures 1-4, the solid line C-) is indicated by an electrical connection, the Stdash-dashed line (-.) Is an optical link, and the line - - -) shows a kinematic link of a point leaving a trace on the screen 4.

5 When the shutter 11 approaches the spring contact 14 fastened to the screen 4 via the second relay 16 and the contacts 23 of the switching unit 1, the second electric motor 8 switches off: alternating through the second screw pair 9 the curtain 11 simultaneously switches on the contacts 24 and switches to the electric stopwatch 5 (for example , serial IGR-01). The task of the subject is to mentally continue moving the point in the shaded area of the screen and when crossing the point with the marker line on screen 4 mark the point of intersection with a pencil with spring contact 12. As a result, the first relay 15 blocks itself and through the contacts 22 turns off the first motor 6, moving first screw pair 7 probe 10. Simultaneously through

5 pins 25 the electrical stop 5 is turned off.

The proposed device works as follows.

When the illuminator 2 is turned on on the screen 4, it projects the image from the slide, which represents a certain curved line. Dvigupguyus with constant speed, the curtain 11 creates the illusion of movement of the subject.

The proposed scheme provides the ability to change the speed of rotation of the motor shaft by changing the resistance in the power supply circuit of electric motors.

Thus, the proposed device allows an operative assessment of the anticipating properties of a person, which determine the basic psychological mechanisms in the activity of a human operator.
