Abstract

Objective: to study the relationship of sensorimotor interhemispheric asymmetry and the functional state of operators, their psychological characteristics and the effectiveness of professional activity. Materials and methods. According to the results of measuring the time of a simple visual-motor reaction of both hands, an individual asymmetry index was calculated, the dynamics of which was observed among the operators during the 24-hour shifts. Results. Pronounced relationship of sensorimotor asymmetry, the functional state of operators, their psychological characteristics and the effectiveness of professional activity. Duty shift operators with pronounced right-handedness (IIA value ≥ 0.11) are less susceptible to a state of fatigue during round-the-clock duty. Conclusion. An indicator is proposed - an individual index of sensorimotor asymmetry and criteria for its assessment. It has been established that, based on the values of the individual asymmetry index, one can indirectly assess a person’s predisposition to carry out operator activities in the conditions of daily duty (2 figs, 1 tabl., bibliography: 6 refs).
