RESUMO
The individual differences of autonomic support of intellectual activity (simple and complex sensorimotor reaction, storing and reproduction to the screen of the monitor of the visual information) were studied. Intellectual computer tests passing speed is a relatively steady individual characteristic, revealed in different kinds of activity. Students who reached high speed and accuracy in performance of intellectual visually-motor tasks were characterized high lability of autonomic indices, which manifests itself in a change in the absolute values and relationship of the characteristics of heart and respiration rate in accordance with activity stages. These changes were specific for each form of activity and were connected with the results of the tests. In an initial condition these students differed high values of TP and power of LF and HF ranges of heart rate variability at a LF/HF ratio close to unity.
