Description

The invention relates to devices for the study of psychophysiological reactions.

The purpose of the invention is to increase the reliability of the assessment and didactic characteristics of the device.

In FIG. 1 shows a structural electrical diagram of the proposed device; figure 2 is a block diagram of programs; in Fig.Z - switching unit; Fig. 4 is a pulse shaping unit; figure 5 - block input response actions; figure 6 - block registration.

The device comprises a program block 1, an indicator 2, a Start button 3, a first, a second block 4. 5 pauses, a switch 6. A pulse forming unit 7, 8 single pulses forming, the first, second OR elements 9, 10, one-shot 11, delay unit 12, differentiation unit 13, analog key 14, tone frequency generator 15, n response response input units 16 and registration unit 17.

Block 1 of the program contains the first shaper 18 Morse code element I 19,

a second Morse code generator 20, and a clock generator 21.

Switch 6 contains AND elements 22, 23, OR element 24.

. Block 7 contains a T-trigger 25, an element And 26, a sensor 27 of random pulses.

Blocks 16 contain head tiptrons 28, buttons 29, 30, AND elements 31 ... 34, OR elements 35, 36.

Block 17 contains a counter 17 of the number of presented characters, counters 38 of correct answers and counters 39 of incorrect answers.

The device operates as follows.

Previously, the head in block 1 of the program using the switches (not shown in the drawing) sets: in the shaper 20 signs of the Morse code with an odd number of elements that the subject should mark by pressing the button 35 of the right hand (or vice versa). The pulse duration of the one-shot 11 is set to 3 s.

When the device is turned on, the counters 39, 38 and 37 are set to their initial state. From one of the outputs of block 7, a unit potential is supplied to the input of switch 6. For example, if the first output of the T-flip-flop 25. which is the first output of block 7 has a single potential then it is applied to the first inputs of the response input units 16 and to the second input of the And element 22 / which is the second input of the switch 6.

To present identification signals, the manager presses the 3 Start button. The pulse from its output goes to the second input of the generator 21, which is the first input of the program unit 1, and turns it on. The same pulse through the element OR 24, the first input of which is the third input of the switch 6, is supplied to the first inputs of the elements And 22, 23. Since At the second input, the element And 22 has a unit potential, the pulse from its output - the second output of the switch 6 - will go to the input of the driver 20, which is the second input of the program block and provides a binary combination of the Morse code sign at its output. The code combination from the output of the shaper 20 through the OR element 9 is fed to the first input of the analog key 14, the frequency of the output of the generator 15 is supplied to the other input of the output. they determine the presence of an even (odd) number of elements in it and press the button 30 (29), respectively, with the right (left) hand.

At the end of the combination of signs at the output of block 5, a pulse is generated. This pulse through the OR element 10 will come through the first input of the registration unit to the counter 37, which will record the sign presented for identification, and to the one-shot 11. The one-shot 11 generates a pulse lasting 3 seconds. which arrives at the third inputs of blocks 16. Over a period of three seconds, the subjects must give an answer, i.e. press one of the buttons 29 or 30. Let the subjects be presented with a sign having an odd number of elements. The test person on block 16i correctly oriented and presses button 29 with the finger of his left hand. By applying a pulse from its output to the second inputs of elements And 31, 33. Since to the first inputs of the elements And 31, 32, which are the first input of the block 16, a unit potential is supplied from the first output of the block 7, then an impulse appears at the output of the And 31

which through the OR element 35. the output of which is the second input index 1 of the registration unit 17. Counter 38 captures the pulse of the correct answer. If

the test person on the block 16 is not oriented correctly and presses the button 30 with the finger of his right hand, the pulse from the output of which goes to the second inputs of the And 32,34 elements, then the pulse appears from the output of the And 32 element

which through the OR element 36, the output of which is the second output of block 16, enters the counter 39, where an incorrect answer is recorded.

Similarly, responses from other blocks 16 will be committed.

Upon the termination of the pulse from the output of the one-shot 11, the subjects are unable to respond to the code sign heard in the headphones

Morse code.

The trailing edge of the pulse from the output of the single-vibrator 11, acting on the differentiation unit 13, will provide a short pulse at its output, which is supplied to the driver 8, from the output of which a single pulse is fed to the input of the delay unit 12 and the first input of the And element 26 of block 7 If at the second input of element And 26 there is a unit potential from the output of the sensor 27, then the pulse from its output will change the position of the T-trigger 25 to the opposite, i.e. at its second output, the unit potential is to be applied to the second input of elements

and 23, which is the first input of switch 6.

The pulse from the output of block 12 through the OR element 24 will go to the first inputs of the elements And 22 and 23. Since at the second entrance

element I28 has a single potential, then the pulse from its output will pass to the second input of the shaper 18, ensuring the supply of the next sign for the subjects from its output.

After the subjects present all the characters of the sequences programmed in each of the drivers 18 and 20, the first outputs of the latter show unit potentials that are applied to the first and second inputs of the element And 19. At the output of the element And 19, a pulse is generated which, acting on indicator 2, the transparency will be highlighted. Verification is completed, and upon entering the first input

generator 21, turn it on.

The head records the results of counters 37, 38, 39, i.e. total number of presentations: correct timely answers and incorrect answers of each of the subjects.

Untimely answers of each of the subjects are found by calculating the sum of the readings of the counters AND 38, 39 of each subject from the readings of the counter 37. In accordance with the developed technique, the suitability of each subject for training in a radio operator is determined by quantitative indicators.

To break into groups with approximately the same characteristics of the skill of coordinated actions, a repeated check is carried out, in which the response time is reduced first to two, and then to one second (by the switch on single-vibrator 11).
