[Changes in the volume of acquired and processed information of students with regard to age]

Some aspects of the functional state of the higher nervous system and capacity for work are analyzed in the present paper, by work that is fixed in volume and duration. The capacity visual-motor analyzer, the speed, quality and accuracy of the processed information were more precisely established in 161 students from grades 9, 10 and 11, trained at 19 Unified Secondary Polytechnical School, Sofia. The table of Hartridge was used for that purpose. The results as a whole reveal a reduced volume of the acquired information as well as the accuracy of the processed information after the classes in the age groups studied, with no essential discrepancies in the indices discussed.
