The invention relates to medical technology and can be used for diagnostic purposes in taxological research and professional selection.

The aim of the invention is to expand the field of application by making it possible to study the reaction rate of the subject's selection,

1 shows a functional diagram of the device; 2 is a schematic diagram of the device; on fig.3 - a schematic block diagram of the match .15

The device for psychological studies contains a block 1 of responses, a block 2 of coincidence, a program block 3, a generator of 4 random numbers, a block 5 of control, a counter of 6 symbols, a block 7 of time measurement, a block 8 of information display.

Block 1 response contains (see figure 2) key 1 9, key 2 10, key 3 11, key 4 12.25

The control unit 5 includes Start keys 13 and Stop 14, switch 15 Modes 1 - Mode 2 of the device operation mode, trigger 16, element 2 OR 17, elements 2И 18 and 30 19.

Comparison unit 2 consists of five multiplexers 20-24 (see FIG. 3). Program block 3 contains a read-only memory (ROM). The random number generator 4 includes a high frequency pulse generator 25, elements 2 and 26 and 27, as well as counters 28 and 29 pulses.

The time measurement unit 7 is made of df in the form of a 30 second pulse generator connected in series and a pulse counter 31.

The information display unit 8 contains decoders 32-35, an indicator d5 36 of the number of characters, an indicator 37 of presented symbols, an indicator 38 for setting the variant and an indicator 39 of time.

The device works as follows: - Q at a time.

The subject presses the Start key 13, while the high potential (1) is fed to the direct input of element 2 OR 17 of block 2, the single (S) input of the RS flip-flop 16, the inputs of the reset (R) of the counter 6 characters and the measuring block of time. As a result, RS-trigger 16 goes into 4

A high potential appears at the output of element 2ILI 17 and is fed to the inputs of elements 2I 26 and 19, thereby allowing the high-frequency clock (6-10 MHz) passing from the generator 25 output to the counting input (C) counter 28.

If the switch Mode 1 - Mode 2 15 of the device operation mode is in the upper position - Mode 1 (see FIG. 2), then at the inputs of the element 2I 19 and accordingly at the output a high potential that enters the input of the element 2И 27 ensures the passage of pulses the output of the generator 25 through the element 2 and 27 to the counting input (C) of the counter 29.

Thus, while the Start 13 switch is pressed, the pulse counters 28 and 29 consider the pulses coming from generator 25, and since the frequency of the pulses is large and the holding key of the Start 13 when it is pressed is unstable (varies from experiment to experiment), then at the moment of release key 13 in the counters 28 and 29 will form random numbers. One of the numbers in a two-bit binary code comes from the outputs of the counter 28 to the outputs of the decoder 33, which in turn highlights the symbol on the indicator 37 corresponding to the input code.

Since (so far) the keys 9-12 of unit 1 are not pressed, the inverse output of multiplexer 24 (see FIG. 3) is high potential, which is fed to one input of element 2 and 18, at the other input of which there is already a high potential coming from the output The RS flip-flop 16, therefore, the output of element 2I 18 also has a high potential, which is fed to the enable (V) input of counter 31. From this point on, counter 31 starts counting pulses from the generator output of 30 second pulses. The counter 31 in a two-bit binary code reads from the output (s) of the counter 31 to the input of the decoder, where they are converted into a decimal code and then displayed on the time indicator 39.

The random number generated in the counter 29 modulo 24 is projected onto the address input of the Permanent Memory Storage Device 3 (ROM) with memory organization on 24 eight-bit cells (for example, IC 556РТ5). The ROM is pre-recorded information of the corresponding type.

The code from the output of the ROM unit 3 is supplied to the address inputs of multiplexers 20-23, which commute lines from keys 9-12.

If, for example, cell 1 is selected in the ROM of unit 3, the signal from key 1 9 passes to the input of multiplexer 20, from key 2 10 to input of multiplexer 21, and key 3 11 to input of multiplexer 22 and from key 4 12 - to the input of the multiplexer 23.

At the same time, the signal from the output of the ROM of the block 3 through the decoder 33 is fed to the input of the indicator 38, on which the option of matching the keys 1 9, 2 10, 3 11, 4 12 is highlighted according to which, for example, the symbol O is located with key 1, the symbol D is key 2, symbol Q - key 3, symbol 8 - key 4.

The binary code of the symbol from the output of the counter 28 is fed to the address inputs of the multiplexer 24, thereby connecting one of the multiplexers 20-23 corresponding to this symbol.

After some time, which is determined by the reaction rate of the subject, he presses one of the keys 9–12, which corresponds to the highlighted option. If the button is pressed correctly, the high potential passes through one of the multiplexers 20-23 and the corresponding input of the multiplexer 24 is fed to its direct output and then to the counting (C) input of counter 6, while its content is increased by one.

Thus, the contents of counter 6 correspond to the number of characters presented (correctly guessed), and using decoder 32 from the display on display 36.

At the same time, the low potential from the inverse output of multiplexer 24 is fed to the inverse input of element 2 OR 17, thereby turning on the random number generator to the input of element 2I 18, thereby prohibiting the counting of time.

If the switch Mode 1 - Mode 2 16 is in the lower position (according to the diagram), i.e. device

works in mode 2, then when you press the keys 9-12, the pulses to the input of the counter 29 do not pass, since the low potential from the switch 15 through the element 2I 19 enters the input of the element 2I 27. In this case, the option is set when you press the Start key 13, the high potential from the output of which through the switch 15 enters element 2I 19 and removes the blockage of the passage of pulses from the generator 28 to the counter 29. After the device finishes working, the subject presses the key

Stop 14, while the high potential arrives at the zero (R) input of the RS flip-flop 16 and sets it to the zero state and the low potential from its output through element 2and 28 blocks the time counting by the counter 31.

The speed of the selection reaction is estimated by the average time per figure, defined as the quotient of dividing the total task time by the number of completed figures, and the accuracy of choice (A) is estimated by the formula

where N is the total number of presented figures;

Thus, the use of the invention makes it possible to investigate and objectively evaluate the reaction rate of the selection of subjects in normal and pathopsychological conditions.

The use of the device provides an objective assessment of the psychological state of the subject by determining the speed of the selection reaction.
