Age-related features of the organization of motor activity in 6- to 16-year-old children

The use of the KID-3 diagnostic set for a large-scale examination of 6- to 16-year-old children helped reveal substantial age-related differences in the mechanisms of the regulation of motor activity on the basis of correlation of the specified parameters: velocity, precision, smoothness, velocity of readjustment of motor tasks, etc. The study confirmed the leading role of visual control in the realization of the motor function in 6- to 9-year olds. The mechanisms of movement regulation, i.e., a transition from a primarily monitoring mechanism of control to one based on a preliminarily formed motor program, is changed substantially by nine–ten years. These changes are possible only at this age, since it is in this period that substantial shifts take place in the morphofunctional development of the frontal cortical areas, and they become more important in the control of the activation processes, which determine and regulate motor activity. The age of nine-ten years is transitional in the formation of the mechanisms of central commands. This efficient movement control mechanism only begins to form at this age, and its formation is completed at age 14.
