INFORMATIVE OF ELECTROPHYSIOLOGICAL INDICATORS FOR ASSESSING THE FUNCTIONAL STATE IN THE DYNAMICS OF VISUAL WORK

Abstract

It was shown that the most informative for functional state estimation is an electrodermal resistance (EDR) asymmetry's index. This index was calculated as the module of differences between the left and right hand indexes. The analysis of factor structures was performed in test persons groups where the asymmetry of EDR increased or decreased as the result of visual work. It was found that dynamics of EDR asymmetry is connected to visual system's indexes change. The index of EDR asymmetry increased in conditions of visual fatigue development. Thus, it is possible to use it for express estimation of visual system's functional state.
