Some psychophysiological characteristics, and peculiarities of attention have been assessed in two groups of students and further correlated with their academic achievements. It is shown that the "good" and "excellent" correlate with higher aspiration level, leadership style, and egocentricity. Ability to concentrate attention was 2.7 times higher in this group as compared with the "satisfactory" group. Weak motivation, low level of demands upon themselves result, it appears, in lack of self-confidence and, consequently, in low level of achievements.
