The device works as follows: 3qM,

Power on. In the initial state, register 16 and 21 are set, counters 27, 42, 43 and 49. Registers 29 and 48 are entered one at a time, with the unit in register 29 being set to the position corresponding to the number of stimuli initially expected by the subject, for example ti. Then, using the Record button, connect the generator 13 to

5 clock inputs of the driver 14 and through the element 18, to the unit potential from the output of the inverter 28, to the input of the register 16. The pulse from the driver 14 through the element 17 to which the potential of the inverter 28 is applied,

and the adder 15 is fed simultaneously to another input of the register 16, fill it randomly, and to the input of the counter 27, counting the number of received single pulses. From the outputs of the counter 27, pulses are fed to the inputs of the corresponding elements AND 30. As soon as their number reaches the value corresponding to the position of the unit at the output of register 29 (five), which is applied to the input of the IZO element, a pulse appears at the output of the latter, which OR 33 is fed to the input of the inverter 28, removes a single potential from the elements And 17 and 18, turns off the shaper 14 and the information input of the register 16 and stops the supply of clock pulses. The unit potentials recorded in the register 16 are fed to the inputs of the one-shot 19, the pulses with the output of which, arriving at the corresponding inputs of the register 21, record the unit to that bit to which the input of the corresponding one-shot 19 or 20 is connected.

When ready, the subject presses the Exposure button and the signal from the output of the generator 12, entering the input of the multivibrator 22, produces a single pulse, the duration of which is equal to the exposure time set in advance. The impulse from the output of the multivibrator 22, coming through the OR element 24 to the control input of the switch 25, provides the supplying ignition voltage from the output of the source 26.

The subject visually captures both the numbers and the placement of the indicators 36, on which these numbers are displayed. Then, it reproduces the stored information by pressing the button 37 of the highlighted indicator 36 and the button of the 38-digit row corresponding to the highlighted digit of the indicator 36.

When the button 37 is pressed, the outputs of the corresponding register 21 are switched from the indicator 36 to the element AND 39. If the stig /: ul is displayed in the indicator 36, then a single potential is fed to the input of one of the elements And 39. When the student correctly reproduces this stimulus using button 38 from generator 12, a unit is recorded through the corresponding element AND 39 and element OR 40 into counter 42.

If the stimulus or indicator 36 on which the stimulus is displayed is incorrectly indicated, then two units do not go to one of the elements 39 at the same time and the counter 42 does not count. In this case, after reproducing all the stored information, indicator 39 does not turn on and the subject must repeat the cycle from the beginning or press the Exposure button of the block 4 repeatedly. If the answer is incorrect, the corresponding trigger 56 does not work, the output potential of the AND-NE element 55 is ensures the passage of potential voltage from key 25 to indicator 36. Indicator 36 again indicates information coming from registers 21. In the case of a correct answer, the corresponding trigger 56 is translated into one the alternative state of the potential of the voltage from the output of the element And 39 and thereby ensures the passage of the pulse voltage arriving at the second input of the element AND NOT 55. At the time of coincidence of the potential from the divider 53 with the potential of the output of the trigger 56 at the input of the element And 54 zero potential , and as a result, at the output of the latter, a zero potential prohibiting the operation of the indicator 36. At the end of a long pulse from the divider 53, at the output of the element AND NOT 55 - a single potential that permits the operation of the indicator 36. With the arrival of the next and The pulse indicator 36 is turned on again. Thus, the indicator 36 is illuminated with a discontinuous light for a period of time determined by the duration of the closing of the key 25, indicating the correct answer of the subject.

At the end of the answer to all the highlighted indicators 36 and the numbers on them not counter 43, which receives pulses from the output. yes element OR 41 is overflowed. The pulse from its output through the elements AND 31 and OR 35 is fed to the information input of the prohibition element 44. Since the potential input 44 of the input element has zero potential from the output of the element OR 34, the pulse from the output of element 44 enters the input of the delay element 45 and the indicator 47 , warning the subject of an error (and repeating the presentation of the same information). After a delay time of 2 s, the pulse from the output of element 45 turns off the indicator 47 and through the element OR 46 enters the input of the multivibrator 23, which produces a single pulse. This impulse provides repeated flashing of indicators 36 and numbers on them.

If the subject correctly reproduces all the information, then after playing the last (fifth) stimulus, the output of the counter 42 is an overflow pulse, which through the elements AND 31 and OR 34 enters the input of the element. AND 50 and the input 44 prohibiting the input, preventing the indicator from turning on 47, i.e. element 44 does not allow an overflow pulse from the output of counter 43,

At the same time, the pulse from the output of the generator 12 through the button 38, the element OR 41 and the element I 50 is fed to the input of the register 48 and moves the unit to the next bit. The unit potential from the output of the register 48 is fed to the input of the one-shot 20 one of the nodes and the pulse from its output moves unit in register 21, i.e. makes a mistake

From the output of the element And 50 a pulse also goes to the element 51 of the delay, turns on the indicator 52 Indicates an error and is recorded in the counter 49. After a delay time of 2 seconds, the pulse from the output of the element 51 turns on the indicator 52 and through the element OR 46 enters the input of the multivibrator 23 which gives a single impulse. This impulse provides flashing of indicator 36 and digits of them. The student visually looks for, and then fixes the indicator 36, in which he found an error, and the digital value of the error.

If the subject correctly reproduces the error, the latter is recorded by the counter 49. At the same time, the pulse from the output of the element 50 is fed to the input of the register 48 and moves the unit to the next bit, thereby ensuring the introduction of a new error.

If the subject incorrectly reproduces the error, the indicator 47 lights up and stimuli are presented again. With the same error. The pulse from the output of the element OR 46 is fed to the second input of the counter 49 and sets its true position.

If the subject correctly reproduces another nine errors, then the counter 49 overflows. The overflow pulse enters the input of register 29 and translates unit 8 to the next position, the sixth. A zero potential is applied to the input of the inverter 28c for output of the next element AND 30 through the element OR 33. The unit potential, from the output of the inverter 28, enters the inputs of the elements 17 and 18 and ensures that the additional unit is written to register 16, t, e, takes into account the number of stimuli presented in the next cycle by one. The pulse from the output of the adder 15 enters the counter 27, transfers the unit to the next position and provides the appearance of a single potential at the first input of the next element And 30, to the second input of which the unit potential is fed from the output of register 39, The unit potential from the output of element 30 is fed through the element OR 33 and the inverter 28 and removes a single potential from the second outputs of the elements And 17

and 18, stopping the flow of clock impulses.

The cycle is repeated first, similarly to the indicated one, the subject is presented to

identifying six stimuli i. Training conditions are automatically complicated.

The invention makes it possible to increase the efficiency of the professional selection of operators by evaluating the operative memory by repeating information when making mistakes, going over to presenting a larger number of characters while correctly identifying the errors entered, detecting their errors by the operator,
