Abstract

Introduction. The aim of this study is to estimate the associations between psychometrics and EEG parameters and to attempt to pick out some EEG-markers as an instrument in further investigations of constitutional integrity of the human organism. Materials and methods. The subject of the study is a sample of 89 Moscow psychology students. Patients were divided into groups with low (1), medium (2) and high (3) levels on the scales of a questionnaire of self-regulation ability (Morosanova). Monopolar EEG recording was conducted. Kruskal-Wallis analysis and Mann-Whitney U-test were applied as criteria of differences between groups on EEG parameters. For correlative analysis Spearman’ rank correlation coefficient was used. Results. For the scales «Planning», «Modelling», «Programming», «Assessment» in males, significant associations with EEG power parameters, increased for group 1, were revealed. In females for the scale «Planning» correlations with one power parameter and 4 interhemispheric coherences were found – all parameters were increased for group 3. For the scale «Modelling» in females valid correlations, mainly with intrahemispheric coherences, were found (maximal value in group 3); for the scales «Programming» and «Assessment» – with interhemispheric coherences (similarly, maximum fixed in group 3). High level of mutual connection between the above-mentioned scales and their close association with total value of self-regulation were revealed. The scales «Flexibility» and «Self-independence» showed most independence. Results and discussion. The fact of lower values of EEG power parameters in the male group with high level on the scales «Planning», «Modelling», «Programming», «Assessment» may reflect strategy of functioning CNS with lower expense of energy of individuals with high level of self-regulation. Revealed sexual differences of the character of psychophysiological associations correspond to literary data. The results correspond with data of our previous investigation, which revealed the priority role of scales «Modelling» and «Self-independance» in females. Conclusion. The main finding of this study is that EEG power marks the level of self-regulation in males, EEG coherence – in females. Scales «Flexibility» and «Self-independence» (and «Modelling» for females) show lower connection with total level of self-regulation. Without connection with sex EEG power parameters are decreased, and interhemispheric coherences are increased in groups with high level of self-regulation.
