Features of the Development of the Cognitive Sphere in Children with Different Online Activities: Is There a Golden Mean?

The paper presents the results of a comparative study of cognitive functions in preschoolers (5—7 years old, n=50), elementary school students (7—11 years old, n=50), younger adolescents (12—13 years old, n=53), and older adolescents (14—16 years old, n=47) with different intensity of daily use of digital devices: low, medium, controlled high, and uncontrollably high. A battery of neuropsychological methods was used to study the state of cognitive functions. The main differences in accordance with online activity were found in groups of elementary school students and younger adolescents: results were obtained confirming that children using the Internet at medium frequency (1—3 hours per day) are effective in performing a number of cognitive tasks (regulation, control, dynamical praxis, verbal and visual-spatial functions, and neurodynamics). In this study, a certain optimum of online activity time was outlined for different age groups, in the presence of which higher levels of development of certain cognitive functions are recorded.
