A Hardware–Software Complex for Diagnostics of a Human Being’s Psychophysiological State during the Solution of Cognitive Tasks

The psychological state of a person can change under conditions of cognitive load. Excessive cognitive load can lead to distress, which reduces performance. Diagnosis of changes in psychophysical state in the process of performing cognitive tasks is important for human health and increasing the efficiency of his work. Therefore, the purpose of the study was to develop a hardware and software complex for diagnosing the psychophysiological state of a person in the process of solving cognitive problems. Electroencephalogram signals were recorded using a developed device and a certified standard recorder during a biological experiment. A comparison was made of the diagnostic capabilities of the developed hardware–software complex and a serial device. A hardware–software complex has been developed for diagnosing the psychophysiological state of a person in the process of solving cognitive problems using an electroencephalogram signal. The developed system showed sensitivity and specificity values close to those of the serial recorder. Using the developed complex, the electroencephalogram channels suitable for diagnosing the psychophysical state were selected. The developed hardware–software complex can be used to diagnose the psychophysiological state of a person in the process of performing cognitive tasks.
