Introduction. The researches, directed at achievement of operators’ high level reliability, steering sailor, in particular, are actual in modern psychophysiology ergonomics and occupational medicine.
Purpose of the study. On the basis of studying regularities of functioning of the central nervous system under the influence of information loading of different degree of intensity to develop approaches to forecasting the reliability of camera activity of ship experts by characteristics of reaction to the moving object.
Materials and methods. The group of steering sailor (30 men 22—24 years of age) was investigated for performing the presented work. A special computer program for revealing characteristics of reaction on moving object (RMO) in various information load¬ings has been created. The indicators of RMO accuracy, depending on the reaction timeliness, movement direction of a marker and various level of information loading were chosen as the characteristic of reliability of an operator’s activity.
Results. The significant deterioration of indicators of inhibitory type of RMO accuracy among steering sailor has been revealed under the increase of information loading, which does not depend on the RMO direction. Two significantly different subgroups of individuals by the level of RMO accuracy, having different maintenance strategy to reliable performance of operator’s activity, caused by peculiarities of manifestation of the interhemispheric asymmetry and, also, quantitative and qualitative structure of inter¬relations of RMO accuracy indicators under different intensity of information loading. The presence of prevalence of inhibitory processes in the central nervous system can cause a significant do negative influence on reliability of the information processing. Conclusion. Two subgroups of respondents, different by excessive information loading more essentially by parameters of inhibitory type of RMO accuracy have been separated. There was revealed the existence of different mechanisms and strategies of high reliability maintenance of information processing, based on the steadiness or unsteadiness of interhemispheric asym¬metry patterns of nervous processes in the brain and different intensity of regulatory processes in the central nervous system in individuals with the best (60 %) and the worst (40 %) indicators of RMO accuracy, respectively. The developed decisive rules by indicators of RMO accuracy are sufficient for forecasting the high reliability of steering sailor occupational activity with 96,66 % accuracy.

Key words: reliability of occupational activity, reaction to the moving object, steering sailor
