(54) DEVICE FOR THE CONTROL OF PSYCHOPHYSIOLOGICAL CHARACTERISTICS OF OPERATORS

one

The invention relates to computing devices and can be used in determining the psycho-physiological qualities of a person.

A device for controlling the attention of a person is known, comprising test and tester consoles with a set of buttons and contacts interconnected by a logic circuit, a recorder, a switching unit, and indicator devices 1.

The disadvantages of this device are the narrow functionality, which is explained by the fact that only the attention of the subject is evaluated and that the device is practically unsuitable for mass tests, and the lack of reliability of the estimates obtained.

It is also known a device for evaluating human memory features, comprising a trigger signal node, a trigger trigger, a time stamp generator, a table highlighting node, a time stamp counter, an AND scheme, an input resolution trigger, a keyboard input register, a comparison circuit of the input and a reference response; register of standard answers, counter of correct entries and registration node 2.

This device, although it provides some increase in the reliability of the estimates obtained in comparison with the above, but also has narrow functionality.

Of the known devices, the closest in technical solution to the invention is a device containing a test counter, the output of which is connected to the input of the table changer node, to the input of the node

10 reference responses and to the input of the encoder, the output of the table changer node is connected to the single trigger trigger input, the output of which and the output of the time stamp generator are connected through the AND circuit to one input of the error recording node and time, to the second input of which one of the analysis circuit outputs is enabled answers, the inputs of which are connected to the outputs of the node of the reference responses and the key input register, and the other output is connected to the counting input

20 of the correct answer counter, the output of the correct answer counter and the output of the encoder are connected to the inputs of the comparison circuit, the output of which is combined with the inputs of the start trigger trigger, the correct answer counter and the count input of the test counter 3.

The device works as follows. The test number stored on the test counter sets the number of the table with the test image that must be presented to the subject. According to this number, a group of reference responses is prepared in the reference response node and, using an encoder, the code of the number of correct answers is given to the comparison circuit. If the tasks of the test are executed correctly and the results are entered correctly on the keyboard, the comparison circuit generates a signal that takes the test counter to a new state, thus a new table will be presented to the subject.

The results (errors and elapsed time) are recorded by the registration node, which allows an assessment of the features of attention to be made.

The device under consideration has a low reliability of the estimates obtained, since it does not exclude non-productive time and additional errors, and also has narrow functionality, because it only explores the peculiarities of the attention of one subject.

The purpose of the invention is to improve the accuracy of control and expand the functionality of the device.

This goal is achieved in that a device containing a response analysis block, connected to a result recording unit, an answer input node and a test counter, is connected via an encoder to the first input of the comparison unit, the second input of which is connected through the time recording unit to the output of the AND element, and the output to one of the inputs of the memory element connected to the other input to the device input, and the output to the input of the test counter and the first input of the And element, the second input of which is connected to the generator, the input input node connected to the display unit; a test change unit, a task number counter and a cyclic test presentation and answer search unit are added, connected to the response input node and a task number counter that is connected to the answer input node, the test change unit is connected to the memory element output and kinematically associated with a cyclic test and test answer block containing sequentially connected switches and indicators connected to the inputs and outputs of the block, respectively.

The drawing shows a block diagram of the proposed device for monitoring the psycho-physiological characteristics of the operators.

It contains the generator 1, the element And 2, the element 3 of the memory, the counter of 4 tests, block 5

test changes, time recording block 6, encoder 7, comparison block 8, response analysis block 9, response input node 10, indication block 11, task number counter 12, switch 13, indicator 14, result recording block 15 and cyclic presentation block 16 tests and finding answers.

In the proposed device, the output of the generator 1 is connected to one input of the element AND 2, the second input of which is combined with the output of the memory element 3 and the inputs of the test counter L and the test changing unit 5. The output of the AND 2 element is connected to the input of the time recording unit 6, the output of which and the output of the encoder 7 are connected to the inputs of the comparison unit 8, and the output of the block is connected to the input of the memory element 3, to the counting input of which the start bus is connected.

The output of the test counter 4 is combined with the input of the encoder 7 and one input of the response analysis unit 9, the second input of which is connected to the output of the response input node 10, to the inputs of the display unit 11 and the counter 12. The output of the counter 12 is connected via switch 13 to the indicator inputs 14 of block 16 each electrified test board from the kit used. The output of the block of analysis of answers 9 is connected to the input of the block 15 of the registration of results.

In the proposed device, the test change unit 5, the counter 12, the switch 13, the indicator 14, the response input unit 10 and the display unit 11 are placed on each panel of the subject.

A device for monitoring the psycho-physiological characteristics of the operators works as follows.

Claims (3)

After the subject is familiarized with the test execution rules, the tester excites the memory element 3, at a signal from which, first, the test changing unit 5, consisting of the engine and the regulator, is turned on, and the first test is presented to each subject, using a counter 12, the switch 13 and the indicator 14 are indicated (if necessary) by the first task to be performed and the corresponding contacts of the response to it are excited; secondly, the unit is entered into the counter of 4 tests, which sets up the response analysis unit 9 for the first test and causes the encoder 7 to output to the comparison unit 8 a code combination corresponding to the exposure duration of the first test; thirdly, from the generator 1, through the element And 2, time pulses start to flow into the time recording unit 6, thereby starting the countdown of the test execution time. The subject performs the test task assignment; he deliberately touches the node’s elecroslector 10 of those contacts on the board, which he considers to be the answer. In this case, the signal taken from the contacts goes to the response analysis unit 9, where the correctness of the solution of this task is evaluated, to the counter 12, to transfer it to a new state, and to the display unit 11, with which the subject is signaled about the fact of input. The results of the analysis of the response to the task being performed are recorded by block 15. In performing the following test tasks, the device functions in the same way. At the end of the exposure time of the first test, the comparison unit 8 is triggered, the memory element 3 is reset, the response analysis unit 9 is turned off, and the device is preparing for the next test. The operation of the device when performing subsequent tests proceeds similarly. Tests have shown that this device has almost completely eliminated the loss of time by the time of solving and eliminated errors associated with the input of results, thereby significantly increasing the reliability of the estimates obtained. The tests also showed the practical feasibility of using this device in the case of versatile multi-test group and individual tests, its high reliability and accuracy in controlling the psycho-physiological characteristics of control system operators.
