The invention relates to computing and medical technology.

The aim of the invention is to extend the functionality by providing tests on various types of Platonic tables and correcting errors by the test subjects.

Figure 1 presents the scheme of the intended Elatonov table, the type of which depends on the nature of the tests.

Node 3 serves to generate signals of the correct or erroneous response when the rod touches the conductive platform of the console found by the subject during the test.

level from unit 1 when the signal end 15 of the probe touches the conductive area. The signal end 15 of the probe is a movable electrically conductive rod connected to the input of the node 3. After touching the pad with the probe 2, the subject presses on the rod, which, during its movement, turns on the mechanical-.

Stencils have dimensions equal to the size of the working floor of the console 1, and

Dinen with the device case, a normally closed contact and a normally open contact - with the inputs of the node 3. 45 are made of opaque electroPul 1 is made as a desktop-type device with an inclined panel 17, the working field 18 - of which is divided into cells, emitting material, for example plastics, getinaks, etc. The working side of the stencil is divided into a number of cells with dimensions equal to the sizes of electrons from 50 wire sites isolated from each other. An image of a sign in an electric contact with a nominal or red color and made with a probe 2 is applied to each square electrically conductive pads 19 and made with a probe 2. Each of the pads has an electric through hole 30. The stencil chosen for the combination is connected to the corresponding contour test At the time of the electrical connector 20, 55, the baffle field 18 of the panel 17 and rigidly mounted in the housing of the console is secured. Through the holes in the stencil 1. The working field 18 of the panel 17 of the subject during the test forms the basis for fixing the probe 2 to electrically conductive at zero potential, and pressing the probe) or its error (pressing the probe when they touch an erroneous site with a positive potential.

those. high signal level). In the case of a correct BT, a pulse appears at the output of element 23. If the answer is incorrect, it is at the input of element 24,

and after inversion by element 25, at the output of node 3.

The decoder 7 serves to provide a signal, for example, a zero potential, to one of its outputs, depending on the code of the number at its input.

Block B is used to select and install a specific type of Platonov table and the corresponding circuit for connecting the outputs of the decoder 7 to the electric conduction sites. Block 8 includes a set of interchangeable stencils 29 (FIG. 3) in the form of a different type of Platonov table and corresponding to each table of electrical contact inserts 31 (from fO

Turn on the device. The (zero) counters 5 and 12 and the block 10 are reset to the initial state. In this case, the decoder 7 and block 8, under a certain, for example, zero potential, are installed one of the sites of the console 1, which is to be found by the subject. The remaining sites are under a different, high potential.

Block 9 with the help of decoders 6, 11 and 13 displays zero: the state of the counters 5 and 12 and the zero time count and the duration of the study on signals from the block 10.

The experimenter announces to the subject the conditions and the research method and during the submission of the signal to the subject from the beginning of the experiment, for example, by voice or by turning on any kind of signal (light, sound), simultaneously starts the time countdown at block 10 and starts block 14. Block 10 forms and carries on

the current time from the beginning of the test-25 block 14 through the adder 4 signals gtmetki time following the selected interval, for example 1 with each other. These signals are fixed by block 14, for example, in the form of short pulses of a certain amplitude.

remote control panel Corresponding to this table, Plateoy's contact insert has a definite pair-wiring scheme with jumpers of contact pairs. One of each pair of connector pins is connected to one of the electrocontact pads, and the other to one of the outputs of the decoder 7. This design provides a signal from a specific output of the decoder 7 to one of the console sites in accordance with the selected type of Plato's table. The order of occurrence of signals at the outputs of the decoder 7 at the same time remains unchanged and does not depend on ti-ff on the Platonov table. When changing the type of the Platonov table, it is also necessary to change the contact insert at the same time, setting the corresponding to this table. 20

Block 9 provides, for example, a display of the number of numbers correctly found by the subject at a given time, the number of erroneous answers,

tani, as well as sound and (or) sign signaling (at the request of the experimenter) about the erroneous response of the subject.

Block 10 is used to form time stamps, for example, at a pace of 1 second or 0.1 second and measure time intervals between the start and end signals after a certain time interval has passed, the subject finds, for example, the correct answer and touches probe 2

After a certain period of time, the subject finds, for example, the correct answer and concerns probe 2

The device operates in the following manner with the image of the sign required at once. During the test, the sign (for example,

Before the operation of the device, the number 1 in black in the case of the experimenter selects a specific red-black table). When you click the view of the Platonov table and the reference sequence of the search for the characters of this 40 table, the subjects are examined. Usually, the type of table and the sequence of searching for signs on it are in tight communication and

The subjects on the probe 2 turn on the mechanical switch 16 and, through the closed middle and third contacts of the switch, the zero potential flows to the input of the node 3. In this case, at the first output of node 3, a 45 Signal (impulse) is formed, which corresponds to the correct response. This signal is fed to the input of the counter 5, and through the summator 4 - to the block 14. In the last one, for example, the deviation of the pen

In this case, a 45 Signal (impulse) is formed at the first output of node 3, which corresponds to the correct answer. This signal is fed to the input of the counter 5, and through the summator 4 to the block 14. In the latter, for example, a pen deflection occurs

Using block 8, the experimenter installs a stencil on panel 1, on which signs corresponding to the selected table are applied, and sets the specific reference sequence-50 of the recorder in a certain direction to search, for example, by replacing the amplitude corresponding to the correct switching insert or changing the position switches, go change the state of any other system response.

The signal arriving at counter 5 changes its state by one, for example, transfers it from state 0 to state 1. At the same time, block 9 displays, for example, the number 1 using the decoder 6. At the same time, the switch 7 switches its output signal from the first output corresponding to the zero (initial) state of counter 5, JO to another output (for example, the second), corresponding to the position of counter 5, storing 1. This signal from the decoder 7 goes through that block 8 to that area, which corresponds to barely J5 th sequence of characters kbtory must find the subject. This site (for example, corresponding to the number 24 in red) is under zero potential-20, and all the others under high potential. This construction of the device circuit provides a programmable switch-over. The moment when the subjects find the last character and the reference search sequence, the decoder 6 provides an indication of the number of this sign in the search sequence (counting the areas after the correct indication of the sign by the test participants about the sign. 25 example, the number 49 on the display of block 9) at the expense of the programmable for the case table 7x7) and-gives the switching sites at the time of removal of the signal to stop the block 10. The last probe 2 after the first touch of the right The time stamping of the Vilnius pad is eliminated when the adder 4 is left and, through the decoder, 11 errors of the device due to 30 are shown on the display of block 9, which reflects the total bounce of the probe contact 2 and the time of the test. During the test, the scoreboard displays the current time from the beginning of the test. At the end of the research process 3, the display of block 9 displays the total research time, the number of correct and erroneous answers. At the output of block 14, a data carrier (for example, a recorder tape) will be received, on which, against the background of the current time stamps, the pulse of a different amplitude and duration is recorded as the moment of receiving correct and incorrect answers from the subject. The obtained 45 information allows further data processing (for example, finding out the law of the distribution of time intervals of character search steps) to determine the professional suitability of the subject.

Similarly, the device works with the following correct actions of the subject.

In case of error of the subject, i.e. when they indicate a sign that does not correspond to the reference search sequence, a high potential is present on the indicated probe. Node E at this touch produces an error signal at the second output. This signal passes through the adder and deflects the pen of block 14 by another value compared with the deviation from the correct answer signals and time stamps. This is how the error of the subject is recorded. At the same time, the error signal from node 3 goes to counter 12, changes its state

from zero, for example, to the fixation of the number 1, which causes an indication in block 9 of the number 1 using the decoder 13. This means that the subject made the first error. The same signal study containing the signal comes from node 3 to block 9 and the unit for setting the test code;

includes, for example, an audible alarm. The contents of the counter 12 and the formula of the invention

A device for conducting a mental set of tasks, the input of which is connected to the output of the code setting unit

The number of errors indicated in block 9 increases by 1 with each next error of the subject, i.e. incorrectly found site with a sign that does not correspond to the next position of the reference search sequence.

At the same time, error signals from node 3 do not arrive at the input of counter 5 and do not change its state, and therefore do not switch the zero potential from the site with a sign corresponding to the reference search sequence to a high potential.

Only after the test subjects indicate the mark on the platform correctly, does the device enter the mode of operation described above and corresponding to the correct search sequence.

At the moment when the subjects find the last character and the reference search sequence, the decoder 6 provides an indication of the number of this sign in the search sequence (for example, the number 49 on the display of block 9 for the case of table 7x7) and issues a stop signal of block 10. The latter stops issuing time stamps to the adder 4 and through the decoder 11 on the display of block 9 displays the total time of the study. During the test, the scoreboard displays the current time from the beginning of the test. At the end of the research process, the block 9 display shows the total research time, the number of correct and erroneous answers. The output of block 14 will receive a data carrier (for example, a recorder tape), on which, against the background of current time stamps, are recorded in the form of pulses of a different amplitude and duration the moment of receiving correct and incorrect answers from the subject. The information obtained allows further data processing (for example, finding out the law of the distribution of time intervals for the search for signs) to determine the professional suitability of the subject.
