The object of research - the people of intense mental work and people in different functional states durind the modeling of operator activity. Purpose - to establish the quality features of operator activity, and patterns of changes in the functional state of the person during monotonous work. Research methods - hygiene, psychological, physiological, psychophysiological, mathematical. Research has shown that individuals with both the "moderate" and "high" emotional stress, intense informational load cause unidirectional reaction reducing subjective assessments of their relevant mental states. In the subgroup with a "high" stress an "imbalance" of indexes is maintained long time after removal of the load, suggesting that about "residual effects" of stress action on neural centers. For people resistant and susceptible to the development of monotony allocated two phases of changing the functional state during performing the simulated monotonous operator's work. The first (initial) phase with duration of 20-40 minutes, is characterized by: for persons prone to monotony, a gradual decrease in the reaction speed and its variance, with a sharp decline in the speed of reaction at the end of phase; for individuals resistant to the development of monotony - a gradual increase in the reaction speed and the increase in its dispersion. During the development of the second phase of changes in the functional state is characterized by: for people prone to the development of monotony, the stabilization of a sufficiently low level of reaction and a gradual increase in their dispersion; for persons not lean to monotony - a gradual increase in the reaction speed and the reduction of its variance. The regularities of the influence of intense information load on the representatives of subgroups "high" and "moderate" emotional stress, while in the subgroup with a "mild" emotional strain detected significantly more positive relationships between these parameters, indicating a stable consistency and coherence of the processes of transformation of emotional changes, compared with the subgroup of a "high" stress. People, resistant to monotony, are different by levels of development of their individual and typological characteristics, and have greater force mobility and lability of nervous processes, compared to prone ones to developing of monotony. The classification methods of levels of proclivity and resistance tj development of to the monotony state are developed, which may be based on an analysis of objective and subjective characteristics of human activity. The validity and reliability of the classification of the states is checked by the developed indicators.
