The invention relates to medical technology and can be used to study the mental characteristics of subjects during professional selection, vocational guidance, and psychological diagnostics in neurological and psychiatric clinics, as well as in related areas.

The Raven Progressive Matrix Test is known for studying the spatial-constructive human mental activity. The test includes 60 matrices depicting various compositions of abstract figures with missing elements. The subject should identify the principles of relationships between abstract figures and select the missing elements among the proposed patterns. The test is divided by increasing difficulty into 5 series (A, B, C, D, E) with 12 matrices in each; for each correctly solved task, the subject receives 1 point. Known modifications of the test, involving the scoring with certain weights, reflecting the degree of complexity of the proposed tasks.

The disadvantage of the known test is the laboriousness of its implementation, which requires the experimenter to spend considerable time on processing the results, especially considering the weights of the difficulty of the tasks. This limits the use of the test for mass research.

Special devices designed to automate the processing and processing of the results of applying the Raven test are not known.

Closest to the present invention, there is a device for psychophysiological research containing a test panel, a persistent storage device, a comparison circuit, a control circuit, a pulse distributor, a control valve block, a meter block, an experimenter console, and a pulse generator. The known device makes it possible to obtain information that quantitatively characterizes conceptual thinking, but cannot provide for obtaining the characteristics of its spatial-constructive mental properties, extracted, for example, on the basis of the Raven test.

The aim of the invention is to increase the reliability of the research results.

In the device, the analyzer analyzes the results of processing information about the testing conditions and makes a decision about the accuracy or erroneousness of the test person's reaction, ensuring the switching of the modes of operation of the device blocks. The permanent storage device stores the codes of the numbers of the elements of the matrices corresponding to the remaining time, the codes of the points 5 | assigned for the correct answer, the codes of the average time allotted for solving the tasks. The test panel provides the issuance of the test response codes, as well as an indication of the correctness or inaccuracy of the decision being made.

The shaper response time provides the formation of pulses encoding the response time of the test and

digital response time code.

The test presentation block provides visual presentation of tests to the subject, and the integral assessment unit of thought activity provides the calculation

and an indication of the integral assessment of mental activity.

When working with the device, the subject performs the following modified method of working with the Raven test. Having received

5, the image of the matrix and its elements, the subject receives information about how much time is given to him to solve the task, and this time after presentation begins to decrease. Thus, the numbered one has the ability to determine how much time he has left before changing the matrix. The subject must press the button with the number corresponding to the number of the element, which in his opinion corresponds to the proposed matrix. If the subject makes the right decision, then the right solution transponder lights up, the matrix is changed, and the subject is counted with the corresponding number of points and the partial sum of his integral assessment of mental activity is calculated. At the first wrong decision, within the allotted time limit, the subject is credited with an error and the error transponder lights up, but the test matrix does not change, giving the opportunity to rethink the result and make a new decision. If the erroneous decision is repeated in the allotted time limit, the error transponder lights up again, another error is counted for the subject, and the test matrix is changed. If the subject does not fit into the time allotted to him for a response, then he is considered an error and the matrix is changed.

The device works as follows.

Before the device is manufactured, the block 2 of the permanent memory with the help of special programmers widely used in microprocessor technology records information necessary for the implementation of the test according to a given technique. At the same time, in the first groups of bits of 1 cells of block 2 information is entered on the average time tcpi, which the subjects spend on solving the 1st test matrix. This time can be obtained on the basis of statistical analysis of the feasibility of the test by a control group of people. In particular, tcpi can be chosen as the time limit devoted to solving every 1st Raven test matrix according to its degree of difficulty. At the same time, the solution of the test matrix, the difficulty of which is estimated at 1 point, is given 40 seconds, 2 points - 1 minute, 3 points - 1.5 minutes, 4 points - 2 minutes, 5 points - 2.5 minutes, 6 points - 3 minutes, 7 points - 3.5 minutes, 8 points - 4 minutes. The number of points accrued for the correct decision depending on the number of the task and the test series is presented in the table.

In the second groups of bits 2 of the block 2 of the permanent memory, information on the number of points q charged for the correct decision on the table is entered, and on the third groups of bits 3, information on the number of samples, the choice of which is considered the correct task solution.

During the test, the test matrix is presented to the subject on the screen of block 3 of the presentation of the test.

In the initial state, the test presentation block 3 presents the subject with the first matrix with variants of the missing elements on the matrix. The bulbs 26 and 25 10, respectively, of the error transponders and the correct solution are extinguished and the transparencies located on the console 4 of the subject 4 are not displayed.

At the beginning of operation of the device, when 5 is turned on, the first address, at the output of block 2 of the permanent memory, codes are set out from the first memory location. The first group of outputs of block 2 of the constant memory is given the code of the average time allotted for the execution of the tcpi task, to the atomic group of the outputs - the code of the corresponding task score, to the third group of outputs - the code of the element number N3 corresponding to the correct solution. At the moment of readiness for operation, the Start button is pressed in block 3 of test presentation, the output of which produces the signal OST. By this signal, the persistent memory unit 2 is transferred from the zero address to the first,

0, the di score code is rewritten into analyzer 1, where it is converted into a time code assigned to the task solution (at the start of the work, a time code allocated to the first task). The value of this code is displayed.

5 analyzer 1 using the block E display the remaining time. At the same time, the shaper 5 of the reaction time is turned on, generating at its first output a sequence of pulses ti, 0 encoding the reaction time of the subject. These pulses, entering the analyzer 1, are used to form the decreasing time remaining for the subject to decide on the matrix, which as previously indicated by the test unit 9 indicating the remaining time of the analyzer 1. Thus, the subject is told how much time he has to think about the task stays on

0 solution (at the initial stage of the first) task, and at the second outputs of the response time generator 5, the code of the reaction time value tki is formed. In addition, the momentum Ost. on the remote 4 test

5, the quotation of the transporants of the correct solution and errors is made (if transports were included in the previous stages of the work). When the subject makes a decision about which element corresponds to the set standard, he (according to the instructions) presses a key with the corresponding block number 21 of the keyboard located in the test unit 4, the key pressed code is fed to the first group of outputs of the test unit 4 connected to the analyzer inputs 1. If the test subject's reaction is correct (the key code pressed coincides with the code selected from the third group of outputs of the constant memory unit 2), the analyzer 1 at its fourth output generates a signal correctly reaction of n, the ignition console 4 transporent correct test solutions while at the first output pulse is generated by the analyzer 1 Fr comprising block 3 Prev detection test, which changes the test matrix pred exhibited by the subject. The same signal provides information recording in block 7 of the integral assessment of mental activity, filed on all its inputs, except for input 7. Thus, information is transmitted to block 7 of the integrated assessment of mental activity information, necessary to calculate the partial sum of the integral indicator of intellectual activity formula

Ho - JfLft.

as well as information on the number of test matrix entries from counter 6 - Sk. Which is used to determine the condition for passing the entire test.

After the delay time g after the signal Fri, the analyzer 1 generates a signal Sb. In its second output, which shuts down the response time shaper 5, stopping the generation of pulses ti. Through the delay time TI after the signal Fri, when the test presentation unit 3 presents the test subject , at the input of the test setup block 3, an OST signal is generated, which changes the memory cell selected from the fixed memory block 2, rewrites the dt point code into analyzer 1, where it is converted into a time code assigned to solve the problem, including t generator 5 and extinguishes the reaction time transporant correct solution of the test panel 4. Next, analyzer 1, in the case of the correct reaction of the subject, works according to the rule described above, changing the test matrix and transmitting the next piece of information to block 7 of the integrated assessment of mental activity. If the subject makes an erroneous choice of the element missing in the matrix, and he has time to solve the task, then the analyzer 1 generates and fixes the error of the subject, the code of which is fed to the sixth outputs of the analyzer 1. From the third output of the analyzer 1 by a signal on the console 4

the error transponder is ignited, but the signal from the first output of the analyzer 1 is not generated, the test matrix is not changed, and the information in block 7 of the integral evaluation of the mental

no activity is transmitted. If the subject repeatedly presses the key of the keyboard unit 21 on the remote 4 of the subject during the time limit allowed for the task solution, then with the right choice

The analyzer 1 at its fourth output generates a signal of the correct reaction n, which lights the transient of the correct reaction, and the signal Fr from the first output starts the operation of the device along

the correct solution algorithm described above. If the missing element is chosen again incorrectly, the analyzer 1 again fixes the error, adds it to the previous error value and exposes

The new error number code on the sixth output bus. In addition, a repeated error leads to the appearance of the Co signal at the fifth output of the analyzer 1 and to the appearance of a pulse F at its first output. Momentum

The PT includes a test presentation block 3 that changes the test matrix, and information is received in block 7 of the cognitive cumulative assessment. Unlike receiving information with correct

in case of a repeated incorrect reaction, in block 7 of the integral assessment of mental activity, the sixth input transmits a signal Co, which informs what to consider as a partial sum of the integral

the indicator does not follow. Thus, the previously accumulated NO result does not change. Further, as before, the shaper 5 is turned off by the signal C0 from the second output of the analyzer 1

5 of the reaction, and through the delay in the output signal of the test, the signal Ost. Is generated, changing the contents of the information at the output of the block 2 of the permanent memory. Further, the work cycle is repeated by

0 described algorithm.

Thus, when the wrong element is selected again erroneously, made within the time limit allowed for the solution, the presented matrix is changed, and the error message Co is transmitted to the integral evaluation unit 7. which cancels the reception of the current values of tcpi, b and tki. If the subject does not have time to make a selection of the missing
