the position to see the correct and incorrect answers, while the correct answers will be accompanied by an intermittent luminescence of the indicator with a frequency determined by the frequency of the generator of 13 clock pulses and the division factor of the frequency divider 53.

The device works as follows.

Turn on the power. Registers 16 and 21 are set to the initial state, counters 27, 42, 43 and 49 are entered. 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 presented to the subject, for example 5 Then, using the Record button (not shown), the generator 13 is connected to the clock inputs of the imaging unit 14 and through the element I 18, to the second input of which a single potential is supplied from the output of the interval 28, to one input of the register 16. Impulse from the imaging unit 14 through the element And 17, on the second input of which odaets potential from the inverter unit 28 and the adder 15 is supplied simultaneously to the other input register 16, it is filled at random, and input to the counter 27 counts the number of pulses received by the unit. From the outputs of counter 27, pulses are fed to the first 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 attached to the second input of the corresponding element AND 30, the output of the last appears the pulse, which through the element OR 33 is fed to the input of the inverter 28, removes a single potential from the second inputs of the elements AND 17 and 18, turns off the driver 14 and from the information input of the register 16 and stops the supply of clock pulses. The unit potentials recorded in register 16 are fed from its outputs to the inputs of one-oscillators 19, the pulses from the outputs 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 the test subject is ready, he presses the Exposure button (not shown), the signal from the output of the generator 12, arriving at 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 element OR 24 to the control input of the key, provides

the ignition voltage from the output of the power source 26.

The subject visually captures both the numbers and the placement of indicators on

which highlighted these numbers. Then it reproduces the stored information by pressing the button 37 of the illuminated indicator and the button 38 of the digital row, yes | corresponding to the highlighted figure on

0 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 symbol 36 is displayed in the indicator 36, then a single potential arrives at the input of one of the elements 39. If the learner correctly reproduces this stimulus using button 38 from generator 12 through the corresponding element AND 39 and the element OR 40 into the counter 42

- unit is written.

If the stimulus or indicator on which the stimulus is displayed is incorrectly indicated, then one 5 two units temporarily do not flow to one of the elements 39 and the counting counter 42 does not lead. In this case, after reproducing all the stored information, indicator 36 does not turn on and the subject must repeat the cycle from the beginning or

0, by resolution, presses the Exposure button of block 1 again. In case of an incorrect response, the corresponding trigger 56 does not work, the output potential of the NAND 55 element is a single potential, which ensures that the voltage potential passes from the key 25 to the indicator 36. The indicator 36 again displays information coming from the registers 21. In the case of the correct answer, the corresponding trigger 56 is transferred to one state by the potential voltage from the output of the AND block 39 of the registration unit and thereby ensures the passage of a pulse voltage Yeni supplied to the second input of the NAND 55.

5 At the time of coincidence of the potential from the divider 53 with the potential from the output of the trigger 56 at the first input of the element And 54 - zero potential, and as a result at the output of the last - the zero potential prohibiting the operation of the indicator 36.

At the end of a long pulse from the frequency divider 53 at the output of the NAND 55 element, the unit potential that accommodates the operation of the indicator 36, with the arrival of the next pulse indicator 36, turns on again. Thus, the indicator 36 will illuminate with a discontinuous light for a period of time determined by the closure duration of the key 25, indicating the correct answer of the subject.

When the response to all the highlighted indicators and digits to their counter 43, to which impulses from the output of the element OR 41 are received, is overflowing. The pulse from its output through the element AND 31 and OR 35 is fed to the information input of the prohibition element 44. Since the zero potential of the element 44 is supplied with zero potential from the output of the element OR 34, the pulse from the output of the element 44 enters the input element 45 of the delay and the indicator 47, warning the subject of an error (and repeated presentation of the same information). After some delay time equal to 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 gives 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 50 and prohibits the input of element 44, preventing the indicator 47 from turning on 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 pulse also enters the element 51 delay, turns on the indicator 52 Indicate the error and fixes in the counter 49, After a delay time equal to 2 s, 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 pulse provides a flashing of the indicator 36 and the numbers on it. The student visually looks for and then fixes the indicator in which he found the 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 correctly reproduces the error, the indicator 47 lights up and a stimulus is again presented with the same error. The pulse from the output of the element OR 5 46 enters the second input of the bank 49 and sets its initial position.

If the subject correctly reproduces another nine errors, then the counter 49 overflows. The overflow impulse p10 enters the register 29 and transfers the unit to the next, sixth position. A zero potential is applied to the input of the inverter 28 from the output of the next element AND 30 through the element OR 33. The unit potential from the output of the inverter 28 goes to the second inputs of the elements And 17 and 18 and ensures that the additional unit is written to the register 16, that is, it takes into account the number of proposed stimuli in the next cycle by one.

20 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 I 30, to the second input

5 of which the unit potential is supplied from the output of the register 29 The unit potential from the output of the element And 30 enters through the element OR 33 and the inverter 28 and removes the single potential from the second outputs

0 elements And 17 and 18, stopping the flow of clock pulses
