[The effect of motivational and emotional aspects of work on the structure of operator's errors]

The paper studies a motivation effect on an effectiveness of occupational activities of the operators with a different level of anxiety. To do this, the role of professional motivation under co-existence of competing motives as well as the dynamics of interactions of the operators with different level of anxiety under complicated working conditions have been studied. It is indicated that the results of operator activity depends on hierarchical structure of motivation sphere. Emotional tension induced by the main motive may lead to an increment of by-work failures. In a motives conflict situation highly anxious operators are more immune to disturbances than the low anxious persons. A reliability of joint activity of the operators exhibiting a close level of anxiety is higher than in operators with different values of an anxiety level.
