Description

The invention relates to automation, in particular to devices for psycho-physiological research, and can be used in assessing professional suitability.

The purpose of the invention is to improve the accuracy of the device by detecting psychomotor characteristics, the performance of which impaired motor orientation skills, i.e. failures occur.

FIG. 1 shows the structural scheme of the proposed device: FIG. 2 - functional block diagram of the number of questions; in fig. 3 is a functional block diagram of the error register: in FIG. 4 is a functional block diagram.

The device contains a block of input of answers, made on microswitches in the form of a keyboard of a telegraph apparatus, a block 2 of comparison, a block of 3 counters (for generating code, digital, information), a block of 4 counters (for generating symbolic, alphabetic information), the first 5 and second 6 decoders, the first 7 and second 8 blocks of asking the number of questions, block 9 of presenting educational information, switch 10, block 11 of the dynamic formation of questions, block 12 of the registration of errors, fleas 13 of the registration of assessment and the element OR 14.

Block 1 has keys with removable nameplates. Start and Reset buttons (but shown).

Unit 3 includes the first and second ring counters 15 and 16, the first switches 17–20, respectively, RL (right-left) and ON-OFF (on / off) of the right side, left side, and the entire digital series.

Block 4 is formed by the first and second ring counters 21 and 22. The first one is the switches 23-27 (paired), respectively, П-Л, ON-OFF of the left part, the left part and the whole horizontal row to. Oi-Iltury and GR-B (horizontal ps keypad).

Block 11 contains a generator 28 and: puls (with a high frequency of sludge), o.vikovibrator 29 and the element And 30.

Block 13 includes a counter 31 the number of calls. a counter of 32 numbers of prlpilmykh from his (with adjustable number of the answer), slymey IL H 33 and indicator 34 G. ts-p.

a preset counter 38), a prohibition element 39 and a delay element 40. Block 12 contains distribution nodes 12i-12n consisting of trigger 41. key

42 and counter 43.

Block 2 form elements AND 44t-44n, the first and second elements OR 45 and 46, the delay element 47 h the prohibition element 48,

0 Block 7 on its display board copies the location of the keyboard key block 1.

The device works as follows.

Pre switch 10 is set to the DIGITAL position, and in block 3, the switch 17 is in the P position, the switch 18 is in the OFF position, the switches 19 and 20 are in the ON position (Fig. 1).

0The switch on the counter 32 must be set to the position 100. And the switch on the counter 38 must be set to the position 10.

The power is turned on, the generator 28 is started. On the display of block 9, the CI.FRA indicator lights up, instructing the student to work on the digital row of the keyboard of block 1. The learner presses the Reset button, sets the counters to initial condition, then starts the button, providing a pulse to the input one-shot 29. The pulse from the output of the one-shot 29 is fed to the input of e.pement I 30, ensuring the passage through it of the pulses from the output of the generator 28. The duration of the pulses of the generator 28 is hundreds of times shorter than the duration of the one-shot 29, and the numbers pulses coming in blocks 3 and 4 for about odnovibra0 torus action time pulse 29 exceeds a width of the counters 15. 16 and 21. 22. ies taken together.

The pulses from the output of the element AND 30 through the element OR 14 and the switch 10 are fed to the input of the block 3 and through the switch 17 to the output of the series-connected meters 15 and 1G (operating as one counter). oQecn i4nbr) .q is their random state. At one of the outputs of the doshoper 5, corresponding to the state of chico 15 and 16. There appears a unit potential that enters the corresponding input of the unit 7. the input of the delay element -10 and the input of the imaging unit 37. visa at the expense of the middle |

5 at its output short pulse. which is fixed by the counter 38 A sustained pulse from the output of the element 40 through the information output of the prohibition element 39, to the initial input of which a zero potenzisp from the output of the counter 38 is fed. It goes to the corresponding input of block 9, but displays its digital range and motor characteristic, for example P2 (second right), to the corresponding motor characteristic one of the inputs of block 12 - to the first input of the corresponding trigger 4 1, providing the appearance at its output of a single potential that is applied to the control Key input 42.

The trainee according to the highlighted motor characteristic (A2) performs movement on the digital row of the keyboard of unit 1, i.e. makes a strike with the second finger on the key. When hitting the key, the contacts of the microswitch close, which ensures the appearance of a pulse. This pulse arrives at the input of the element OR 45 of block 2 and through the element OR 46 at the input of element 47, the delay time of which is equal to the duration of the operation of the element OR 45.

If the student performed the movement correctly, then an output of the element OR 45 appears impulse, since at the second input of this element AND 44 there is a single potential from the output of block 7, which flows through the element OR 45 to the control input of element 48, to the information input which at the moment a pulse from the output of element 47 is applied, preventing the appearance of a pulse at the synchronizing output of block 2, to the input of block 13, fixing the correct answer in the counter 32, and in the counter 31 - the first answer (working out one movement), and the second outputs trigger 41, returning the latter to the initial state. At the same time, the impulse from the output of the unit 2 enters the input of the one-shot 29, the impulse from the output provides short-term redemption of the motor characteristic, translation of the counters 15 and 16 into the new random state and subsequent display on the digital row of the display 9 of the next motor characteristic.

If the trainee incorrectly performed the motion on the digital row of the keyboard of block 1, a pulse appears only at the output of the element OR 46 and through elements 47 and 48, the control inputs of which are applied to zero input potential of the element OR 45. passes to the input of block 13 The fixer in the counter 31 responds (produced by the movement), and to the second outputs of the keys 42. Fixed about the corresponding counter 43 failure - incorrect execution of the movement by the learner.

With the appearance of the same potential of the decoder 5 unit potential in the 11th time. those. On the 11th repetition of the same motor characteristic, an input pulse appears at the input of the counter 38. which, arriving at the control input of element 39. prevents the supply of a single potential to the corresponding inputs of blocks 8. 2 and 12. This same pulse from the output

0 of the counter 38 through the elements OR 36 and 14 enters the inputs of the counters 15 and 16. Moves the unit potential at the input of the decoder 5 to the next row and ensures that the same motor characteristic is received only a specified number of times (10 presentations).

When fixing the hundredth correct answer (ten for each digit) at the output

0 counter 32 an overflow pulse appears, which illuminates the indicator 34 Stop warning the student (teacher) to take readings from the meters 43 and the counter 31. The number of failures made by the respective fingers of the hand, is judged by the degree of development of orientation skill on the digital p do the keyboard and the need to go to processing in parts (on the right or left side of the digital number of the keyboard), and in the number of answers - on the degree of fitness.

Similarly, the development of a keyboard orientation skill (characters) is performed. For this switch 10

5 is set to the LETTER position, switch 23 - to the position P. Switches 24. 25 and 27 - to the OFF position. and the switch is in the ON position (see Fig. 1). The switch on the counter 32 is set to the ZIO position. and the switch on the counters 38 is left at position 10. On the display of block 9, the LETTER indicator is displayed, which instructs the trainee to work on the entire alphabetic keyboard of block 1.

The learner presses the Reset button. then the Start button, providing a feed from the output of the generator 28 to the inputs of counters 21 and 22. connected in series, im0 .ijAbCOB. which bring the latter into a random state. At one of the outputs of the decoder 6. The counters 21 and 22 corresponding to this random state appear. The unit potential that enters the input of the block 7, the cipher
