0 presentation of educational information, the input of the generator of single pulses is connected to the second output of the time reference block. The drawing shows a block diagram of the device.

5 A device for assessing the professional suitability of operators includes a block 1 specifying the number of characters, a block 2 of presentation of training information, a console 3 of the operator, a block 4 specifying the time, a block 5 of the dynamic display and a block 6 changing numbers.

Unit 1 contains a generator of 7 single pulses, a generator of 8 recording pulses, a two-input element OR 9 and a push-button switch 10.

Block 2 contains 11 and 12 random number generators, switches 13 and 14, memory elements 15 and 16, which can store up to ten four-bit binary-decimal numbers, decoders 17 and 18, which convert the binary-ten code into code of seven-segment indicators.

The control panel 3 contains an indicator board 19 of the subject, including ten seven-segment indicators (19i-19io) of decimal single-digit numbers, a switch 20, a push-button switch 21.

Block 4 contains a switch 22 and a timer 23. Block 5 contains a generator of 24 clock pulses, a binary-decimal counter 25, a decoder 26 that converts a four-digit binary code to a decimal, information boards 27 and 28, consisting of ten seven-segment indicators 27i -27io n28i-28io, respectively.

Unit 6 contains a generator 29 pulse recording, two-input elements OR 30-32, the element 33 delay, the generator 34 single pulses.

The device works as follows.

By pressing the switch 10, a generator 7 is started which generates a single pulse. This pulse goes through the element OR 9 to the inputs of generators 11 and 12, the first of which forms the random address of the cell elements 15 and 16 of the memory in which the random number of generator 12 is written. The generated binary code from the output of generator 11 goes through the data bus to the inputs of the four channel - two-input switches 13 and 14. A four-digit binary code of a random number from the output of the generator 12 enters the information inputs of the memory elements 15 and 16.

Upon completion of the generation of codes at the outputs of the generators 11 and 12, the generator 8 generates a pulse that connects the first inputs of the switches 13 and 14 to the address inputs of the memory elements 15 and 16 arriving at the write inputs of the memory element 15 directly through the element OR 32 it records the random number in a randomly selected cell of memory elements 15 and 16.

After the end of the pulse from the generator 8 output, the switches 13 and 14 connect their second inputs to the address inputs of memory elements 15 and 16, while the low potential at the inputs of memory elements 15 and 16 only allows reading information from these elements.

From the generator 24, a sequence of rectangular pulses is fed to the input of the counter 25, at the output of which a binary code of the decimal number is generated. This code varies with the frequency of the generator 24 and is fed to the inputs of the switches 13 and 14 and further to the address inputs of the elements 15 and 16 of the memory. As this code changes, then cycling of the cells of elements 15 and 16 occurs. The information of these cells through the decoders 17 and 18 enters the inputs of the board 27, 28 and 19.

At the same time, the code from the output of the counter 25 through the decoder 26 synchronously with interrogating the cells of the memory elements 15 and 16 switches on the corresponding display elements of the board 27, 28 and 19. The power on the board 27 and 28 is constantly applied, therefore they display the contents of the cell of the elements 15 and 16 memories constantly.

By switch 10 of block 1, pressing it several times, random numbers are added to elements 15 and 16. As necessary, after completing the set of numbers, switch 21 starts timer 23 and the board 19 starts for the time it detects. At the end of the time interval, determined by timer 23 and equal to the delay time of element 33, the negative potential drop from the output of timer 23 starts generator 34, from the output of which a pulse arrives at the input of element OR 30 and through element 33 at the input of element OR 30. Two pulses are removed from the output of the latter Arrested relative to one another in time as determined by the element 33.

These pulses through the element OR 9 twice start the generators 11 and 12 and the generator 29, the output pulses from whose output through the element OR 31 twice switch the output signals of the generator 11 with random addresses of memory cells, with the address (first) input of the element 16 and through the element OR 32 records information from the output of the generator 12 to the information input of the element 16. Thus, two numbers from ten in the element 16 are replaced.

The switch 22, which is switched to the second position, shuts off the input of the generator 34 from the timer 23 and thus puts the device into exercise mode without automatically replacing the numbers on the board 19. The switch 20 allows the board 19 to be turned on to check the correctness of the numbers it calls after memorizing the numbers. Board 27 shows the information presented to the subject immediately after dialing.

The scoreboard 28, placed next to the scoreboard 27 and inaccessible to the subject, allows the experiment leader to compare the numbers before and after replacing the two bits.

The invention makes it possible to evaluate the professional suitability of operators under the influence of stress factors. The stressful situation, which causes a feeling of confusion, irritation, is caused by the fact that the subjects cannot learn the numbers proposed by them, some of which are unnoticeable for the subjects to change. The alternation of tests with the replacement of numbers and without replacement makes it possible to determine the resistance of the operator to the effects of stress factors.
