Description

DEVICE FOR PSYCHOPHYSIOLOGICAL RESEARCH

The utility model relates to the field of psychophysiology and can be used to test the level of knowledge in educational systems when assessing professional abilities and the like psychophysiological research using testing.

The prior art device for monitoring physiological information, containing sensors for heart rate (pulse), respiratory rate and skin-galvanic reaction, an amplifier unit, a switch, the output of which is connected to the input of an analog-to-digital converter, which is connected to a program unit - a computer microprocessor , and a display (RU 20 10 326 C1, G 06 F 17/60, 1994).

However, the amount of information taken is not in all cases ensures the accuracy of the assessment of the subject's emotional and stressful tension.

The utility model is aimed at increasing the effectiveness of psychophysiological studies.

The solution to this problem is provided by the fact that the device for conducting psychophysiological studies containing sensors of heart rate (pulse), respiratory rate, skin-galvanic response, an amplifier unit, a switch, the output of which is connected to the input of an analog-to-digital converter, which is connected to the microprocessor program unit a computer, and the display, according to the utility model, further comprises a motor activity sensor and a voice response sensor, and the respiratory rate sensor is configured to in the form of a chest respiration rate sensor and a diaphragmatic respiration rate sensor.

The presence of additional sensors expands the spectrum of recorded physiological parameters, which ensures the availability of essential MPKA61BY1 G06F 17/60

much more objective information about the psychophysiological state of the subject.

In FIG. 1 shows a block diagram of a device for conducting psychophysiological studies.

The device contains a sensor 1 for skin-galvanic reaction (RAG), a sensor 2 for chest breathing (DG), a sensor 3 for diaphragmatic breathing (DD), a photoplethysmographic sensor 4 for heart rate (PPG), a sensor 5 for motor activity (YES) and a sensor 6 for voice response (microphone) (GR), amplifier unit 7 (U), switch 8 (K), analog-to-digital converter 9 (ADC), program unit 10 — computer microprocessor (PB), display 11 (D).

A device for conducting psychophysiological studies works as follows.

Corresponding sensors are placed on different parts of the subject’s body for recording physiological parameters, while 1 RAG sensor in the form of two electrodes is fixed on the index and ring fingers of one of the hands, tensometric or optic sensors 2 DG and 3 DD are mounted on the chest and in the diaphragm region, a photoplethysmographic 4 FPG sensor is fixed on the middle finger of the hand, a 5 YES strain gauge is placed on a chair under the subject, and a 6 GR sensor is fixed on the chest next to sensor 2.

During testing, under the control of the device, a series of auditory presentation of several tests to the subject is performed. In this case, the signals from sensors 1, 2, 3, 4, 5, 6 — pass sequentially through the amplifier unit 7, the switch 8 and are processed in the program unit 10 — the computer’s myth processor, and the received information is transferred to the RAM and displayed on the display 11 in the form curves - physical fluctuations in the indicators of the skin-galvanic reaction, the frequency of chest and diaphragmatic respiration, heart rate (pulse), the reaction of motor activity and voice response, histograms or tables.

t

To assess the psychophysiological state, the dynamics and nature of the indicators of physiological parameters are analyzed, a sharp change of which indicates an increased degree of stress-emotional tension, which allows us to determine the veracity of the answer to the test questions and make a conclusion about the level of professional suitability of the subject.
