*3.5.4 Discussion*

In general, according to the results of the study, subjects with left hemispheric dominance reveal higher data on the R. Kettell method scales, which are associated with activity and self-organization, which in general may indicate a greater severity of indices of arbitrary regulation in this group of individuals.

The obtained data correlate well with the results of previously conducted psychodiagnostic studies. According to the data of the conducted experiments, it can be stated that as they mature (as they move from adolescent to older age groups), there is an increase in the indices of volitional qualities of the personality (in the method of M. Chumakov) and the indicators of the sustainability of the choice of color incentives. This is especially clearly manifested in the "left hemisphere" subjects (i.e., with the right-hand indicators of the "crossing hands" test) [2].

## *3.5.5 Conclusion*

The obtained data can be successfully used in solving differential diagnostic problems in sports psychology, including the diagnosis of individual features of the regulatory functions of athletes.

The results show the presence of asymmetry of the third (regulatory) block of the brain according to A.R. Luria. This position is also confirmed by the data of psychodiagnostic studies of adolescents and young men with different lateral features [13, 21] and previously established data that the partial dominance of the left frontal lobe (often in males) is associated with higher rates of goal formation and volitional regulation. Our pilotage studies conducted earlier show that these indicators are less specific (more "blurred") for girls and women, i.e., they are not always confirmed by statistical processing. The results can be used practically to diagnose the individual characteristics of arbitrary regulation in sports psychology when training highly qualified athletes and to predict human behavior in extreme sports [2, 3].
