Abstract
The autonomic correlates of individual differences in the effectiveness of purposive activity during a computer-aided sensorimotor test and computer-aided testing of the level of knowledge of students were studied. Students who reached high results of sensorimotor and academic tests were characterized by lability of autonomic indices, which manifests itself in a change in the absolute values and relationship of the characteristics of heart rate and hemodynamics in accordance with activity stages. These changes were specific for each form of activity and were connected with the results of the tests. The physiological prerequisites of the high lability of autonomic characteristics which ensures the ability of the subject to successfully adapt to the conditions of the activity included high initial values of TP and power of LF- and HF-ranges of heart rate variability at a LF/HF ratio close to unity, reflecting a high level of balanced sympathetic and parasympathetic effects on cardiovascular functions.
