Background. The catechol-O-methyl transferase gene influences the reuptake of monoamines (dopamine, serotonin, noradrenaline) from the synaptic space. The structural peculiarities of this gene are linked with the duration of stay of neurotransmitters in the synaptic gap and the emergence and duration of emotional reactions, which may considerably affect a person’s level of aggressiveness; these peculiarities may manifest as psychophysiological characteristics.
Objective and design. This study investigated the amplitude, spatio-temporal traits and sources of evoked brain activity in men with several genotypes in the polymorphic locus Val158Met in the COMT (Catechol-O-methyl transferase) gene, levels of aggressiveness using the Buss-Darkee inventory, proneness to various types of deviant and addictive behaviors in accordance with the methods of A.N. Oryol and the preferred strategies of behavior during conflict in accordance with the methods of Kenneth Thomas. Statistical processing of psychodiagnostic data included dispersive (ANOVA) and discriminative analyses.
Results. This study found significant differences in the parameters of evoked brain activity components in responses to emotionally charged stimuli (“aggression”, “positive”, “tolerance”, “extremism, terrorism”) compared with neutral images. Student’s t-test (Holms- corrected for multiple comparisons) was used to analyze the EEG-VEP data.
Conclusion. This study confirmed the hypothesis of differences in spatio-temporal and amplitude parameters of evoked brain potentials in young men exhibiting differing levels of aggressiveness. The sources of evoked brain activity determined using sLORETA (Standardized Low-resolution Brain Electromagnetic Tomography) were different between carriers of different genotypes.

Abakumova I. V., Ermakov P. N., Kolesina K. Y. (2016). On analyzing the results of empirical research into the life-purpose orientations of adults of various ethnic identities and religious affiliati. Psychology in Russia: State of the Art, 9(1), 155-163.
The research in question investigates life-purpose orientations and values of various groups of a population living in a multicultural area with a variety of ethnic and religious communities. Members may have different attitudes to one and the same set of values due to their specific cultural traditions and religious guidelines. A common set of life-purpose orientations and values as well as distinctly different ones were identified in the research. It employed an ethno-psychological questionnaire designed specifically to that end and psychometric instruments aimed at identifying the values of the adults of various ethnic identities and religious affiliations. Residents of a multi-cultural area in the south of Russia who belong to different denominations were surveyed. It is stated that there is a substantial difference between the sets of values held by Baptists and Buddhists and representatives of other ethnic and religious groups (Muslims and Christians) participating in this investigation. The survey found that all of the Baptist and Buddhist respondents were described by a high-to-medium level of civil identity. Indifference to ethnic standards and a failure to accept the culture of their own people were found among all of the respondents; it was displayed by a small proportion of Orthodox Christians, whereas all of the Buddhists under investigation had a positive ethnic identity, and a certain proportion of Muslims and Catholics as well as a tiny proportion of Orthodox believers reported that they placed a priority for ethnic rights over human rights. Among all of the denominations surveyed, the majority of respondents surveyed have a positive attitude towards both their own nation and other nations.

The objective of this research was to assess the motivational potential of psychology students using an egoskopiya method. Heart rate and EEG data were recorded while the participants performed the Mehrabian achievement motivation test. Thirty students of the Faculty of Psychology of Southern Federal University who were aged between 20 and 30 years participated. The psychodiagnostic study involved 136 students from the Faculty of Psychology of Southern Federal University who were aged between 18 and 49 years. To determine the lateral organization profiles of sensory and motor functions, a computer-based testing program termed “Profile” was used. The Compact Russian Structure of Temperament Questionnaire (STQ-77) was used to evaluate the features of temperament.
The results revealed that people with a strong motivation to succeed exhibited a predominance of right features in their lateral organization profiles. Their cardiovascular systems were in more activated states than those of the people who were extremely motivated to avoid failure. The observed temperament features of psychology students with different levels of achievement motivation indicated that the level of achievement motivation is related to the properties of temperament such that students with lower levels of achievement motivation (i.e., motivation to avoid failure) exhibited the temperament traits of Neuroticism and Impulsivity in addition to low values on the scales for the Sensitivity to Sensations, Intellectual Ergonicity, and Sensitivity to Probabilities. High levels of achievement motivation (i.e., motivation to strive toward success) corresponded to the psychology students’ propensities for Sensitivity to Sensations, high levels of Intellectual Ergonicity, high levels of Sensitivity to Probabilities and low values on the scales of Impulsivity and Neuroticism.

Pavel N.Ermakov, Oxana S. Saakyan (2013). Peculiarities of brain electric activity in young males and females of different creativity levels. Psychology in Russia: State of the Art, 6(3), 31-40
This article shows that the peculiarities of divergent and convergent thinking in young males and females of various creativity levels are stipulated by a definite EEG frequency-and-spatial arrangement. Young males and females of mixed and left lateral arrangement profiles demonstrate an expressed activity of occipital, central, and temporal areas of both cerebral hemispheres. In young males and females of right LAP (lateral arrangement profile), connections are clearly localized in case of solution of both convergent and divergent tasks. Solution of divergent and convergent tasks may condition certain frequency-and-spatial arrangement of EEG in young males and females with different levels of academic progress and a different lateral arrangement profile (LAP).

Achievement motivation is a psychological category which implies a desire to achieve significant (powerful) results in certain sphere. According to the results of psychophysiological research people who are motivated for success are very active before they are instructed by the researcher which proves that they aimed at the perception of the referent situation and the intense level of expectations. One of the vital issues today is a problem how genes influence human behaviour. Thus on the basis of contemporary researches we can conclude that such influence is regulated by brain processes.
