A device for psychological studies is known, comprising a test unit with key elements and indicators, a random number sensor, a counter, a clock generator, a start button, an OR element, a timer, a switch, two keys and a row indication control units, each of which contains a shift register and control circuits of the indicator element.

This device does not allow to investigate the RAM and the sensorimotorics of the subject, which limits his functionality.

However, this device does not allow accurate recording of answers, since with two or older items in the list it records the answer to only one item and does not allow to automatically switch from the list of memorized items to the mixed list, which limits the functionality of the device.

The purpose of the invention is to expand the didactic capabilities of the device by objectively registering the answers to each old list item and automating the transition from the list of memorized elements to the mixed list.

The goal is achieved by the fact that in the device containing the first pulse distributor, the first, second and third outputs of which are connected to the corresponding inputs of the first switch and the input of the registration unit, respectively, the address code generator,

0 to the sixth output of the first pulse distributor.

Figure 1 shows the structure of the device; figure 2 is a functional diagram of the first pulse distributor; in fig.

5 3 - the same as the first switch; 4 is the same, the second comparison block; Fig. 5 shows the same registration block; Fig. 6 shows timing diagrams explaining an automatic transition to the presentation of mixed lists and alternate polling of items.

The device contains a control pulse distributor 1, drivers of address codes 2 and number 3, encoder 4, switches 5 and 6, block 7 of registers (list of elements), block 8 of registers (list of dietaries), consisting of registers that record and storing bits of ten-digit digits in binary code, shifting register 9, providing distribution of polling pulses, the first unit of comparison 10, designed to highlight the bits of the list of elements and the list of distractors containing the same numbers, block 11 of the presentation of information (with the second unit 12, a comparison unit 12, an operator unit 13, and a registration unit 14 with circuit connections.

Block 1 contains generators of 15 and 16 series of pulses, generators 17 and 18 of single pulses, a shaper of 19-tact pulses (polls), a trigger 20, a prohibition element 21, a counter of the number of presentations (with an adjustable counting cycle), an And 23 and element OR 24.

Shaper 2 includes a distributor of 25 pulses, a key 26, and an encoder

27 (addresses).

Switch 6 contains a driver

28 pulses of equal numbers, elements OR 29, elements AND 30 and 31, inverters 32 and elements OR 33.

Unit 10 includes elements AND 34 and element OR 35. Remote control 13 has buttons 36 and signal lights 37. Block 14 contains elements OR 38, counters 39, and display nodes 40.

Block 12 consists of nodes 12, which include the shaper 41 of the short pulse sadrigger 42, elements AND 43-46, element OR 47, inverters 48 and 49, and element 50 of delay.

The device works as follows.

When the power is turned on, the registers and counters are reset, the triggers 20 and 42 are in the zero position.

A pulse (not shown) is applied to the output of the element OR 24 and is fed to the input of the generator 17. The leading edge of the pulse causes the output of the generator 17 of a single pulse, which through the element 21, which has zero potential at the control input, from the last output of the encoder 27 enters the input of the trigger 20, causing the appearance of a single potential at its output.

The unit potential arriving at the trigger input of the generator 15 includes the latter. At the sixth output of the distributor 1 on Wits, a sequence of pulses with a certain clock frequency.

At the same time, when the power is turned on, shaper 3 begins to work. At the moment of arrival of the pulse from the output of distributor 25 to the interrogator input of shaper 3, one of the last outputs (random) shows a signal that goes to the corresponding input of the encoder 4. The signal in the encoder 4 is converted into a binary code which through switch 5 is written to register 7.

Then, from the sixth output of the distributor 1, another pulse arrives at the distributor 25. In this case, the signal is already on the second output of the distributor 25 connected to the information input of the key 26. In the normal state, the key 26 will pass this pulse to the input of the encoder 27, which will respectively switching in switch 5, which provides the connection of its outputs to the inputs of the next register of block 7. Since at this moment there are no pulses at the polling input of generator 3, the number will not be written to the additional register.

At the next signal from the sixth output of the distributor 1, the distributor 25 generates a pulse arriving at the polling input of the generator 3. In this case, a random digit corresponding to the number of the excited driver 3 will be written to the binary code in the selected regular register of block 7.

Thus, with the subsequent signal on the first output of the distributor 1, the address of the next register will first be selected, and then a random number will be written into it. When random numbers are written to the registers of block 8, block 10 is put into operation, which, using AND 34 elements, compares the numbers recorded in some register of blocks 7 and 8. If the numbers are the same, then the signal from the output of AND 34 element through OR 35 arrives at the prohibiting entry key 26, thereby preventing the address of the register connected by the switch 5 to the encoder 4 from changing. Therefore, when the next impulse appears at the polling input of the next 3 pulse, a new random number will be recorded in the previously connected the switch 8 switch 8. This prevents the presence of old elements in the list of distractors that are in the same categories.

From the last output of the encoder 27, a signal (unit potential) is fed to the input of the trigger 20, switching it to the zero state and turning off the generator 15, to the control input of the element 21, blocking the output of the generator 17, to the input of the And 23 element and to the input of the generator 18. Writing numbers to the registers of blocks 7 and 8 is completed, block 1, the distributor stops issuing pulses from the sixth output and generates a signal at the second output from generator 18, the duration of this signal is determined by the selected exposure time of the list of elements presented for storage ( .ba).

The signal from the second output of the distributor 1 through the element OR 29 enters the control inputs of the elements And 30, which open and connect the outputs of the registers of block 7 through the elements OR 33 to the inputs of the block 11 and to the first inputs of the block 12

A n-bit list of decimal numbers is presented to the subject for memorization.

Upon completion of the presentation of the list of decimal numbers, the leading edge of the pulse from the output of the generator 18, applied through the element OR 24 to the input of the generator 17, will cause a single pulse (Fig. 66) at its output equal to the sum of the pulse durations (pause between pulses a) from the output of the generator 16 and a clock pulse from the output of the imaging device 19, which, through the element 23, having a single potential at the second input from the last output of the encoder 27, goes to the information input of the register 9 and to the input of the generator 16 (fig.bv) and the counting input of the counter 22, fixing the presentation of the first mixed list (of old and new elements), to the input of the imaging unit 19, causing the appearance at its output of a series of clock pulses and to the input of the imaging generator 28. The duration of the signal at the output of the generator 16 is interrelated with the number and duration of clock pulses at the output of the former 19, which depends on the number of elements in the list, and is chosen so that the subject has time to extract the old elements and use the buttons 36 to perform the necessary actions,

The shaper 28 starts working immediately when the device is turned on, and when the signal arrives from the generator 16 input, the generators in it are turned off, the number of zeros and ones will be recorded randomly in register 9 bits. At the time of arrival of the signal from the generator output, 16 units from the outputs of elements OR 29 will open the corresponding elements AND 30, connecting to block 11

the outputs of some registers of blocks 7 and 9. The subject will be presented with a list containing both old and new elements.

When starting shaper 19 (figbg)

the first clock pulse from its output will go to the input from register 9. Since at the input of register 9 there is a pulse from the output of the AND 23 element, then at the output of the first digit

0 register 9 in Vits unit potential (figbd), which goes to the first input of the third group of the block 12 and the input of the first signal lamp 37, located in front of the button (first) 36 glow which

5 warns the subject of a response to a character in this (first) category,

If the subject considers that this bit contains the old element, then he presses button 36 (at the moment of lighting of lamp 37),

At the same time, if there really is an old element in this category, then to the first inputs of the elements And 43 and 46 and to the input

5, inverter 48 has a positive potential applied. When you press the button 36, the trigger 42 is triggered, providing a single pulse to the second inputs of the elements And 43 and 44 and to the input of the inverter 49.

0At the end of the receipt of a single

a pulse from the first input of register 9 to the first inputs of the third group of block 12; its falling edge will cause the appearance of a short pulse at the input of the former 41

5 (fig.be), which goes to the input element 50 and the third inputs of the elements And 43-46. The pulse from the output of the element And 43 through the element OR 47 will go to the first output of block 12 connected to the first group

0 inputs of block 14 (correct answer),

The delayed pulse from the output of the element 50, received at the input of the trigger 42, will return it to its original position.

If in this category there is a new

5 element and the subject did not press button 36 (correct answer), then zero potential is applied to the first inputs of elements And 43 and 46 and to the input of inverter 48. The zero potential from trigger output 42 is applied to

0 the second inputs of the elements And 43 and 44 and the input of the inverter 49. The unit potential from the outputs of the inverters 48 and 49 is applied to the first and second inputs of the element And 45. When a short pulse arrives from the output

5 shaper 41 pulse from the output of the element And 45 through the element OR 47 will go to the first output of block 12,

If in this category there was an old element, and the subject decided that he was new and did not press button 36, then a short impulse

Wits at the output of the element And 46, the third output of the block 12 connected to the third group of inputs of the block 14, in which the missing element is fixed.

If a new element is found in this category, and the examinee has decided that it is old, and has pressed the button 36, then he has made a mistake like a false alarm. A short pulse is detected at the output of element 44, the second output of block 12 connected to the second group of inputs of block 14. The delayed pulse from the output of element 50 will return the trigger 42 to its initial state.

i

At the end of the bitwise signaling of the response on the console 13, a new impulse appears at the output of the generator 16, at which a new mixed list will be presented to the subject and he should again, like the one described above, reveal the old elements. The number of predictions is determined by the supervisor (instructor) and counted by counter 22.

When a pulse (overflow) appears at the output of the counter 22 (FIG. 6 b), the generator 16 turns off (not shown) and enters the control input of block 14 — the inputs of nodes 40, which display the number of correct answers, the number of false alarms and the number of skips. .

The invention allows to expand the functionality of the device by objectively registering the responses to each old list item and automating the transition from the list of memorized elements to the mixed list. Fixing answers in the presence of a new (mixed) list of two or older items located in its place is carried out by recognizing each item in the list. In this case, the sensorimotor reaction is carried out under conditions of limited time by pressing the button of the corresponding discharge, near which the signal lamp is lit. The invention improves the objectivity and accuracy of the evaluation of the test memory, increases the efficiency of psychodiagnostics.
