The goal of this episode of study is the vast analysis of intragroup psychological and physiological associations, enlisting the great number of EEG-parameters at rest and psychometrics. The subject of the study is the sample of Moscow students psychologists aged 18–20 years, 62 males and 130 females. Psychological examination includes tests to estimate anxiety level (Spilberger-Ханин), questionnaire to estimate vegetative lability, questionnaire to estimate self-regulation ability (Моросанова). EEG recording included 10 cortical leads; theta-, alpha-, beta- and gamma frequency bands, was held with the computer encephalograph Neurovisor U. Analysis of EEG parameters held with the Matlab program, statistical analysis with the package Statistica 10. The subsequent analysis dealt with the EEG power and coherency parameters. To evaluate the level of associations between psychological and physiological traits Spearman’ rank correlation coefficient was used. Psychosomatic and physiological/somatic correlation are enlisted for comparison, somatotype components according to Heath-Carter are used as somatic indices. The percentage of significant psychological/physiological correlations, summarized through all EEG bands, is 6.5% for males and 9.7% for females. Females have more frequent associations in theta- and alpha-bands, males in beta band. Females have more frequent significant associations of EEG parameters with the self-regulation parameter «self-independence» and «modelling», most of them in alpha-band, males have more frequent significant associations of EEG parameters with the self-regulation parameter «self-independence» and the vegetative lability level, most of them in alpha-band as well. At the same time the frequency of significant correlation of somatotype components with EEG-parameters is 2.6% for females and 11.3% for males, the frequency of psychosomatic correlations has the comparable level for females (6.7%) and not found for males. The level and frequency of significant correlations of somatic, EEG- and psychological parameters point to the tendencies of the covariability of all three system’s characteristics, though do not allow the reliable prognosis of individual psychological traits based on physiological and somatic parameters. The greater frequency of significant correlations is found for parameters of EEG alpha-band, indices of skeletal soma component for males and mesomorphy for females, self-independence and partly vegetative lability level for both sexes, «modelling» (social conformity) for females only and personal anxiety for males only. Thus the more reliable markers of the mentioned psychological traits at rest are EEG alpha-band parameters and skeletal somatic parameters, electric brain activity more informative for males and somatic status more informative for females.
