摘要：The article presents the results of theoretical and empirical research of the problem of psychological aspects of ensuring the efficiency of professional activity of a Project Engineers in the context of the theory of general and special abilities, the need to take into account the general and individual-typological in the mental development of the subject of labor. The importance of considering professional skills in connection with the intellectual readiness of the subject to the activity and individual style of its implementation is theoretically substantiated. The empirical study revealed the presence of correlations between the efficiency of professional activity, psychological readiness and individual style of activity. The most referent in the description of the professional skills of project engineers are the time of labor tasks performance and individual style of activity, and the organizing factor in the unity of these indicators is the generalization of mental activity, which forms the core of intellectual readiness for work. Correlation analysis of the data allowed us to identify the presence of clear links between: 1) the efficiency of activity by time indicator and ISA: the more ISA corresponds to the reference method, the less time is spent on solving the labor task, and vice versa; 2) between ISA and intellectual readiness for activity; the higher the level of complexity of labor tasks, the higher the level of correlation between these phenomena.
