ABSTRACT

Constant development and an increase in the complexity of equipment due to ongoing technological changes make optimization of the psychophysiological state (PPS) of a person who manages his or her own equipment critically important. The operators’ PPS is one of the predominant hindrances to their efficiency, affecting the safety and reliability of their work, and is a prerequisite for their professional upgrade (Karpoukhina 1985, 1990, 2005; Karpoukhina and One-Jang 2003; Kokun 2006). It is well-known that a mismatch between the objectives the operators have to meet and their PPS is often the cause of equipment breakdown, accidents, crashes, operators’ occupational diseases, and increasing dissatisfaction with the activity they are charged with. Therefore, optimization of the operators’ PPS is directed at the prevention and decrease of the so-called negative praxis conditions induced by factors such as fatigue, strain, and stress and can be considered one of the most important tasks for the modern ergonomics.
