Description

The invention relates to experimental psychology and can be used in research, visual perception, memory, thinking, diagnostics of training and the development of mental functions of the operator, professional selection.

The purpose of the invention is the study of perceptual, mnestic and intellectual processes by intermittent exposure of iconic information. I The drawing shows a schematic diagram of a device.

g The device for psychophysiological Investigations includes a switch 1, a timer 2, a timer 3, a calculator 4, resistors 5 and 6, a constant voltage source 7, a manual start button 8, an operation mode switch 9.

The device operates as follows.

On time relay 2, the total time for submission of tests is set (for example, 100 s). On the time relay 3, set the exposure time of each test (for example, 100 s) and the interval between tests (for example, 900 s), and initiate the program of sequential Presentation of numbers of calculator 4 in accordance with the goals of psychological research (for example, a fragment of the program of sequential random presentation of numbers 2, 43, 756, V / O R RP WG F3, F2, F6, F3, F3, F2, F6, F2, ... F6, F3, F6, F2, V / O R PP 2 P2, 43 RP 756 P6 V /ABOUT). Using switch 9, the device is transferred to the automatic presentation of tests.

After turning on the device, using switch 1, normally open contacts of the output of time relay 2 are closed and the supply voltage is supplied to the input of time relay 3, normally open contacts of the output of time relay 3. are closed, connected through switch 9 to the input of the calculator. Thus, the next step-by-step instruction of the program arrives at the input of the calculator. In this case, the previous number will be calculated on the indicator, and after the normally open contacts of the output of the time relay 3 are opened, in accordance with the interval set on this timer, the next program number will be displayed. Then the time relay 3 works again, the normally open contacts of its output are closed and the number presentation cycles are repeated. The closure (or opening) of the normally open contacts of the output of the time relay 3 leads to the simultaneous opening (or closure) of the normally closed contacts of its output connected to a constant voltage power source. Thus, the DC source circuit is opened or closed, which leads to the removal or supply of voltage to this circuit. These changes are fed to the input of the registrar to identify the distribution in time of the presented numbers and the intervals between them. After the total time for presenting the numbers, time relay 2 is activated, it opens the normally open contacts of its output, the time relay 3 is turned off and the presentation of numbers stops.

The device also provides manual, remote control by presenting digital tests. To do this, using the switch 9, the device is transferred to the manual test presentation mode, i.e. the circuit from the input of the calculator 4 is switched from the normally closed contact of the time relay 3 to the contact of the manual start switch button 8, and the contacts of the input of the calculator are closed and opened, as a result of which digital tests are presented sequentially on the indicator of the calculator 4. In accordance with the program, digital tests are presented. In this case, the clock pulses are applied similarly to those described in the automatic presentation mode, but through the normally closed contacts of the switching button 8.
