Abstract
The process of learning can be regarded as a model of psychological stress, since any active operator has to cope with the tasks of attentive and quick perception and memorizing of information, to work out an adequate behavior model as well as to implement it in practice. Forty-three students (23 – main group, 20 – control group) took part in the estimation of psychological state, personality characteristics, auditory arbitrary memory, the dynamics of attention processes, attention qualities, speed of sensor-motor reaction and thinking operations. The students of the main group ingested the alcohol-free dietary grape polyphenol concentrate Enoant for 20 days at a daily dose of 35 ml. Statistically significant changes, such as (i) improvement of the activity and mood; (ii) improvement of attention, (iii) increase in thinking productivity and concentration of attention; (iv) quantity of the processed visual information and the rapidity of processing; (v) improvement of the examinees short-term and working memory; (vi) increase of intellectual work capacity; (vii) success in task fulfillment, and (viii) diminishing of incorrect actions were observed only in the main group. The Enoant use led to the positive changes of reflexivity regarding emotional-volitional and activity spheres of examinees. Thus, Enoant use increases the reserve of adaptation to psychological stress and it can be used as a countermeasure against psychological stress in personnel. Enoant may also be successfully employed in the control of psychological stress at periods of alcohol consumption restriction and under the risk of alcohol addiction development.
