The article deals with the psycho-physiological indicators of school-age children: functional brain asymmetry, mental performance, verbal-logical and short-term mechanical memory, anxiety. It has been shown that in children and adolescents mental working capacity in ontogenesis increases in all indicators, but girls have higher rates. Boys up to 11 years of age are ahead in terms of the verbal-logical memory of girls, but from 12 to 14 years these parameters are higher for girls, and from 14 years of age there is no difference. At the same time, indicators of logical memory using meaningful phrases are predominantly higher in boys. Differences in indicators of short-term mechanical memory are observed only up to 11 years. Surveyed children are in a state of moderate anxiety, however, the level of anxiety of girls is higher compared to boys.
