LATERALIZATION OF THE BIOELECTRIC BRAIN ACTIVITY AS A PREDICTOR OF MOTIVATIONAL AND COGNITIVE PROCESSES

The conducted research was devoted to the study of influence of the laterality pattern of the bioelectric brain activity on the formation of foreign language acquisition abilities based on the actualization of motivational and cognitive processes. Medical students (n=620) studying at the Foreign Language Department took part in the research. Investigation of the bioelectric brain activity was carried out by EEG with the use of a 16-channel «Neiron Spectr 3» (Russia) electroencephalograph. Aspiration level (motives) was revealed by V.K. Gerbachevskij Inventory (1969). Elers test was used to determine achievement and avoid-ance motivation. The level of state and trait anxiety was assessed by C. Spielberger-Ju. Hanin Inventory. Correlation between the motive choice and peculiarities of the bioelectric brain activity was determined. Being a success marker of foreign language acquisition abilities, the academic achievement is likely to be a reflection of the learning efficiency dependence on the laterality pattern of the bioelectric brain activity, motivational behavior. As a rule, students with achievement motivation predominance (well advanced students) relied on their own ab-ilities, aimed at self-actualization and tried to solve problems requiring effort. The predo-minance of motive of avoidance in the motivational structure of the personality in poorly ad-vanced students of the right profile had a negative influence on the course of cognitive processes, manifested in low efficiency of formation of foreign-verbal abilities.
