Zaporozhets O. Psychophysiological functions and study success of junior pupils with different physical and mental load.

The thesis presents the analysis of psychophysiological functions and study success of junior pupils with different physical and mental load. Investigation of properties of basic nervous processes, sensorimotoric functions, memory and attention and study success of children of junior school age with different regimen of physical and mental activity was carried out. It has been ascertained that functional mobility of nervous processes, sensorimotoric and psychic functions slowly and unevenly develop from 7 to 9 years of age. Children going in for sport showed distinguishing features in their development of separate properties of neurodynamic, sensorimotoric and psychic functions as compared to control group of the same age. Similar differentiating features were observed between children with additional mental load and those with additional physical load. Additional mental and physical load has been proved to be one of important factors which have a positive effect on children's study success. Childrenplaying chess showed the highest successfulness of study. Gymnasts showed study success lower than that of chess-players, but higher than of pupils doing no sports. Evaluation of closeness of connection between study success and psychophysiological functions under study was carried out. Dynamics of connection between functional mobility of nervous processes, functions of memory and attention and study success has been determined. Children with additional physical and mental load showed higher and closer probable correlational connections between study success and psychophysiological indices. Pupils with higher indices of neurodynamic and psychomotoric functions are characterized by higher study success.
