a counting pulse arrives, pulses are also fed to the input of the counter 41. through the element 40 and to the input of the trigger 27. The generator 31 is turned on by the single state of the trigger 27, From the output of the element 40 to the counter input of the counter 36 also a pulse arrives. The generator 31 through the circuit of the counter 32 - the decoder 34 the element 29 determines the minimum speed of information presentation. From the output of element 29, the display indication unit 9 sends a signal indicating the speed of presentation.

When you turn on the device, the first three cycles of the generator 31 control the operation of the device, and every four subsequent cycles provide the cycle of operation of the device.

The first clock pulse on the indicator ANSWER of the display unit of the display 9 highlights the total number of cycles for the entire test period. At the end of this impulse, elements AND 23,17 ensure the formation of a pseudo-random sequence by the generator by 13 pulses of the generator 16. The decoders 14 and 15 form informational and erroneous stimuli, respectively. By the second clock of the generator 31, the search of codes in the generator 13 is stopped, and the decoders 14 and 15 issue a combination of informational and erroneous stimuli to the display unit of the board 9 via the second pulse of the third clock. The third clock pulse again turns on the display unit 9 inQ dikatrR ANSWER, highlighting the number of cycles for the entire test period. By this. device performance monitoring ends about

At the end of the third pulse

5 clocks And 23, 17 elements provide a change in the combination of stimuli at the outputs of the decoder 14 and 15.

The fourth pulse of tact provides the presence of 18 and 19 unit potentials at the outputs of the dividers. . The signal from the divider 19 through the element. IDI 38 in the counter 32 is recorded one. A single potential from the output of the element And 20 provides for the passage of signals from the first output of the group of the generator 2 through block 3 to the display unit of the display 9 for flashing a combination of information

stimuli to be memorized by the subjects. At the end of the fourth cycle by the element I 20, the presentation of the informational stimuli ceases. The fifth clock pulse does not change the state of the elements of the device, since the outputs of the dividers 18 and 19 are, respectively, the zero and unit potentials.

The sixth clock pulse. The state of the dividers 18 and 19 changes, providing, by means of the elements 20. 20, passing information and erroneous stimuli 1 through block 3

Oscillator 2 into the display indication unit 9. The subject, against the background of informational stimuli, remembers erroneous stimuli, the presentation of which stops at the end of the sixth cycle.

With the seventh clock pulse, the Elegance And 22 provides a luminescence on the display 9 of the ANSWER indicator enabling the operation from the console 1.

With the help of the keyboard of the remote control 1, the subject reproduces the memorized

erroneous incentives, causing the appearance. at the outputs of the first and second groups

Remote 1 pulses. If the erroneous stimulus is reproduced correctly and in time, the impulse -c of the corresponding element AND 11 enters the correspondingly strong vibrator 46, and by means of the elements AND 39 and OR 40 and the counter 41 a pulse according to the permitting signal of the generator 2 provides the unit at the second output of the decoder 42. At the same time, the pulse of the element OR 40 in the counter 36 records the correct answer. Due to the pulse duration of the single vibrator 46, one and a half times longer than the pulse duration at the output of the console 1, and the delay of the element 44, longer response time of the total element 11 and the single vibrator 46, the passage of the pulse from the output of the key 10 through the elements 45 and 47 into the correct counter is blocked the responses of the board 9. If the erroneous stimulus is incorrectly reproduced, the state of the counters 41 and 36 does not change.

If the answer is delayed, then there is no pulse at the output of element II, and the signal of the key 10 through the elements. 44 and 47, a delayed response is recorded in the counter of board 9. After the end of the seventh clock cycle, the And 23.43 elements of the sigka-.

At the second output of the decoder-42, the number of cycles is highlighted, on a smaller one. And 23,17 elements - the random combination is replaced at the outputs of the decoder 14 and 15. At this, the first test cycle ends. Subsequent cycles are similar to the first.

jQ If, before the tenth cycle, the subjects had eight and nine cycles correctly, then the counter 32 switches the trigger 37 through the element OR 35, which prohibits the triggering

15 elements 33. After the tenth pulse at the input of the counter 32 at the output of the element 33 there is no signal. The eleventh pulse counter 32 sends a pulse to element 35 and to counter 32,

20 allowing the decryphragger 34, element 292 of the storage element 30, to increase the frequency of the generator 31, and hence the speed at which information is presented. Impulse element

25 and 29 I on the board 9. the next gradation of speed is highlighted, and the element OR 35 sets the counter 36. to the initial state, and the trigger 37 - to the zero state. Block 6 is prepared

30 to analyze the next ten test cycles,

If the imputable exceeds the specified error level, then the zero level of the signal from the trigger 37 elements

The ds 33 zeroed the counter 32, and the OR element 35 sets the counter 36 to the initial state and confirms the zero state of the trigger 37.

After one hundred test cycles, counter-28 zeroes trigger 37, which turns on generator 31. On display 9: the speed at which information is presented and the number of delayed responses is displayed.

Finding the number of detainees от 50 vets and determining the number of incorrect answers by subtracting the number of delayed answers from the total number of errors during the test period makes it possible to most fully estimate the mobility

55 of the operative memory of operators, taking into account the volume of short-term memory and the time of comprehension of actions performed, i.e. degrees of development of motor skills and skills of visual and sensory (motor) orientation; orientation, which allows dividing subjects (the subjects into groups with approximately the same skills and conduct a B04iibM training course with a focus on retesting.
