A device for measuring the reaction time to a moving object (RDO) using an electric stopwatch type PV-53-L, one division of which is 0.01 seconds. The test subjects “can”, by pressing a button, started the stopwatch and stopped it when the arrow reached the specified division on the dial. The time of delayed and the time of leading reactions was determined, then, to estimate the individual tendency to delay, the average value of delay errors (x +) was calculated, and to assess the individual tendency to lead, the average value of lead errors (x-) was calculated. Comparison of the calculated average values gives an idea of the prevailing trend, that is, the time of the RDD [1].

The disadvantage of this device is its complexity for the subject, due to the separation of the functions of input and output of information. This leads to a complication of the subject's actions and reduces the accuracy of measurements of psychophysiological parameters.

The technical result consists in simplifying the design of the device and the functions of the subject by combining the functions of input and output of information in the device by using the touch screen.

The technical result is achieved by the fact that in the device for psychological research, which contains a clock generator, a microcontroller, first and second indicators, an indication unit, a matching unit and a liquid crystal graphic display module connected by a cable to the output of the matching unit, a touch screen and a touch interface controller are additionally introduced screen connected by cable to the input of the microcontroller.

Figure 1 shows the circle presented to the test subject on the screen of a liquid crystal graphic display module, where 1 is a mark, 2 is a point object moving at a given speed around a circle; figure 2 presents the structural diagram of the inventive device.

The inventive device comprises a clock generator 1, a microcontroller 2, first and second indicators 3 and 4, an indication unit 5, a matching unit 6, a liquid crystal graphic display module 7, a touch screen 8, and a touch screen interface controller 9.

Microcontroller (MK) 2 is a standard microcontroller having one free 8-bit port for connecting a matching unit with a liquid crystal graphic display module (LCD), one free 8-bit input-output port for connecting indicators and one free 8 a bit I / O port for connecting a touch screen interface controller.

The matching unit is designed to control a graphic LCD displaying a circle, a mark and a point object moving in a circle, as shown in figure 1. The matching unit generates LCD control signals based on the bit representation of the image data received from the 8-bit microcontroller bus and stored in the on-chip random access memory of the image data.

The first and second indicators 3 and 4 are connected to any of the terminals of the 8-bit port of microcontroller 2.

The touch screen 8 is located on top of the LCD screen and is a standard touch screen with a size similar to the size of the LCD.

The controller interface of the touch screen 9 is used to convert the coordinates of the touch screen 8 into digital codes and transmit them to the microcontroller 2.

The control buttons of the test subject “Start”, “Stop the moving object” and “End of measurements” are formed by software microcontroller 2 and presented on the liquid crystal graphic display module 7.

The device operates as follows. When the power is turned on, the clock generator 1 generates clock pulses at the output of the microcontroller 2. The test person presses the "Start" button, the signal from the touch screen 8 through the interface controller of the touch screen 9 is fed to the input of the microcontroller 2, which generates a digital code at the output through the matching unit 6 to the liquid crystal graphic display module 7. The effect of the movement of the object is created by sequentially switching on the corresponding pixels forming the object on the liquid crystal the metallic graphic display unit 7.

At the moment of the supposed coincidence of the moving object and the mark, the subject presses the “Stop the moving object” button. The signal from the touch screen 8 through the controller interface of the touch screen 9 is fed to the input of the microcontroller 2, a digital code is fixed at its output, the switching of pixels on the liquid crystal graphic display module 7 for a predetermined time equal to 1 second is terminated.

The error value of the mismatch between the position of the moving object and the mark is recorded in the on-chip random access memory of the microcontroller 2, while the lead time of errors is fixed with a negative sign, and the time of lag errors with a positive sign. Then the digital code at the output of the microcontroller 2 is reset, and the measurement process is repeated a predetermined number of times.

Upon reaching the specified number of measurements, the test subject presses the “End of measurement” button. The measured values of the mismatch errors of the point object and the marks obtained from the on-chip random access memory of the microcontroller 2 are sent to the on-chip arithmetic logic device of the microcontroller 2, where the arithmetic mean value of the measured errors of mismatch, which is indicated in the display unit 5, is calculated.

the arithmetic mean value of the measured mismatch errors is indicated, which is indicated in display unit 5.

A negative sign of the arithmetic mean value is displayed by turning on the first green light indicator 3, indicating that lead errors prevail in this series of measurements.

A positive sign of the arithmetic mean value is displayed by turning on the second red light indicator 4, indicating that delay errors prevail in this series of measurements.

In order to simplify the design of the device and the functions of the subject by combining the input and output functions of the device, a touch screen and a touch screen interface controller, connected by a cable to the input of the microcontroller, are introduced into the device.
