Abstract

An examination of 300 students was carried out, aged 9, 12 and 15, in the process of their training, aiming at the establishment of the characteristics of their reactivity to mental loading. Modern psychophysiological and biochemical methods were used in the dynamic follow up of the changes in CNS and neuroendocrine activity. Definite age and sex discrepancies were found, on the base of the analysis, in the CNS reactivity to mental loading. With the growing up, the volume and speed of the work performed were increased and their accuracy enhanced. The boys showed faster reactions and less accuracy at work. The girls were distinguished with a better characteristic of their capacity for work. The curves of the daily and weekly dynamics of mental capacity for work were outlined.
