The block of answers and presentation of images is made in the form of a set of elements, each of which consists of a transparent case with a source of light placed inside it and electrodes on the outer surface of the case.

FIG. 1 shows a block diagram of the proposed psychological research device; HJJ FIG. 2 is a block diagram of the mode setting unit; in fig. 3 - an element of the response block and presentation of images, a general view.

The device contains a start-up unit 1, a mode setpoint adjuster 2, an image program block 3, a two-channel dispenser 4, an imaging unit 5, a response block 6 and image presentation, a generator, pulses, an exposure control adjuster 8, a driver 9, a blocker 10, a signal former 11 answers, selector 12 correct answers, serially connected control circuit 13, memory block 14, block 15 of OR circuits, sequentially switched on selector 16 errors, integrator 17, block 18 for evaluating the integral response characteristic, decoder 19, digital indicator 20.

The unit 2 modes contains a readiness sensor 21, AND 22, OR 23 circuits, two triggers 24 and 25, a time driver 26, a mode setting counter 27, and decoders 28 and 29.

The block 6 of responses and presentation of the image is made as a set of elements, each of KOTqpbix consists of a transparent case 30 with a source 31 of light placed inside it and electrodes 32 on the outer surface of the case.

The device works as follows.

A set of light information symbols are presented to the subject through the transparent case 30 using light sources 31 of the response unit 6 and presenting the image as a text image for a short time (for example, in the form of a flash of 0.5-2 seconds). Spatial signals

The structures of the current test image, a quasi-random presentation of presentation, are formed in the program block 3 images.

In accordance with the instruction, the test subject is offered to reproduce the previously presented image by alternately touching the electrodes 32 of the 6 answers with a finger and presenting the image. In accordance with a specific task, a time survey mode is chosen — a forced or free control mode for the length of the response time. From the output of the control circuit 13, the control mode signals are sent to the start-up unit 1, and the initial conditions signals are sent to the 2 mode setters, the response signals generator 11, the memory block 14, the integrator 17, the start button of the start block 1 sets the start of the test pattern presentation and the start the timing of the first cycle in the forced control mode, and the light indication emphasizes the subject's attention at the beginning of the test presentation.

The output of the enable signal of the start-up block 1 starts a pulse generator 7. The last in the forced control mode is formed by a series of pulses with a predetermined follow-up period, thereby setting the length of the response time for the current Entity. In the free mode, the duration of responses and the generation of single pulses of the generator of 7 pulses are regulated by the subject by pressing the start button of the start block 1.

The output signals of the generator 7 pulses through the unit 8 exposure and the driver 9 is fed to the input of the lock 10 start. The exposure adjuster 8 is triggered by the front edge of the input signal, and the imaging unit 9 is triggered by a falling edge, which ensures noise immunity when switching the test pattern presentation number and the test person’s adaptation interval from the start of the presentation cycle to the start of the test pattern exposure. The shaper 9 generates a signal for the duration of the exposure of the test pattern (0.5–2 s), i.e., a signal for the executive gating of the test pattern in the current presentation cycle. In a sequential circuit, the generator 7 pulses-setter 2 modes-software block 3 shows a two-channel dispenser 4 blocker 10 start-up block 15 of the circuits OR-block 5 imaging form respectively the duration of responses to one presentation (for example 10 seconds in the forced mode or randomly - in free), the position or image number, the spatial structure of the significant and non-significant elements of the presented image, is distributed and

send the pre-gating signals of the current presentation to select answers and image exposure, combine the test response signals (identification signals by the test element of the image) and the exposure signals of the identifiable test image and generate light indications at the output. Unit 2 modes are used as follows. From the sensor 21 readiness through the circuit 22 And the signals of the initial conditions prohibit or allow the passage of signals ready.

In the free mode, the signals of the ready sensor 21 or in the forced mode by the signals of the pulse generator 7 are sequentially through AND 22, OR 23, first trigger 24, time generator 26, mode setting counter 27, second trigger 25, first and second decipher 28 and 29 set the order following the image position numbers at the output of the setting device of 2 modes. From the output of the image forming unit 5, the input of the response unit 6 and the image presentation supply signals that are converted to light in the light source 31. So form a test image of a given duration, spatial distribution and complexity.

According to the instructions, the subject reproduces it on the same block of 6 answers and the presentation of images in conditions of absolute identity of the test and adequate images.

All contacts (responses of the subject) are converted into electrical signals. When a finger touches the electrodes, current from the supply potential from one group of electrodes 32 flows to another group of these electrodes through the galvanic skin resistance of the finger. The response signals from the output of the electrodes 32 of the response unit 6 and the presentation of images are fed to the driver 11 of response signals, where the front and amplitude of the response signals are formed. Then, the responses from the output of the response signal generator 11 are recorded in the memory block 14 for a time from the start of the response to the start of the presentation of the next test pattern. The response potentials from the output of the memory block 14 are fed to the input of the block 15 of the OR circuits and then through the image forming unit 5 to the light source 31 of the response unit 6 and the image presentation.

As responses are received from the subject at the response unit 6 and the image is presented, a recognizable image is reproduced with the individual characteristics of the visual analyzer and memory inherent in the subject and memory (the number of errors and correct answers). The signals of a given current position-number of the image from the output of the program block 3 images through a two-channel distributor 4 are fed to the inputs of the selector 12

Correct answers and selector 16 errors. The second inputs of these selectors receive response signals from the outputs of the drivers 11 of the response signals. Signals of correct answers and errors from the outputs of the correct answers selector 12 and from the selector 16 errors go to the first and second inputs of the integrator 17, where the difference between the number of correct answers and errors is calculated. From the output of the integrator 17, the code of the response signals is fed to the input of the evaluation unit 18 of the integral response response, where the evaluation signal code (the maximum number of correct answers) is normalized, for example, by the level of the relative unit or by the maximum level of one of the point estimates. From the output of the integral characteristic evaluation unit 18, the normalized response signal code is fed to the input of the decoder 19, the response signal code is sent to the selected calculus system, and then its current result is indicated or documented by a digital indicator 20 or letter-digitizer.

So consistently, according to the program, we study, present a number of test images to the subject, and his current integral result of the answers is evaluated in a normalized quantitative form in a given counting system. The current result of the answers of the test at the end of the test program will be its final integral indicator.

The proposed device for psychological research allows to increase the accuracy of the study of the visual analyzer and memory by obtaining an integrated normalized quantification of the visual analyzer and memory, as well as determine the optimal and maximum volumes of the visual analyzer and memory.
