The structure of the Theses: introduction, four chapters, conclusions, practical recomendations, bibliography of 303 references, 143 pages of the base text, 21 figures, 7 tables, 6 annexes. The obtained results are published in 20 scientific works.

Direction of investigation: investigations of the psycho-social factors which contribute to physiological, neuronal, hormonal, metabolic modifications in children and psycho-emotional adaptation. Biology.

The aim: This work was accessment of cognitive indices correlated with emotional and intellectual biorythm, study variability based on the cardiovascular system, centred araund functional stocks and of some parameters of the cognitive activity of the teenagers involved in the instructive educational proces at different stages of the intense intellectual activity.

Methodology of scientific investigation: It has been established, that the caracter of the modification, of cognitive indices of the electroencephalograph during the emotional stress of teenagers at all investigated levels of examinations, adoptive processes, bears an individual character being in indipendence of the functional stocks and are in correlation with the level of difficulty of the traced problems.It has been established a correlation between the cognitiveprocesses and the biological rhythms, cardiovascular, nervous system.

Scientific novelty and originality: It has been undertaken a first attempt to examine the adaptable-compensatory process in dependence of the functional stocks of the students organism. The obtained data prove, that in same time whith the promotion of teenagers to a new step of educational process, the compensatory-adaptive mechanisms the educations of the imbalance of the vegetative regulation processes of function of the cardiovascular system. This study argues dependent adaptative reactions of biological rhythms.

Application value: The obtained results demonstrate that there is a correlation between the cardiovascular parameters and the manifestation of the intellectual capacities, anxiety, argues dependent adaptative reactions of biological rhythms. Implementation of scientific results: in the process of didactic activity at the State University of Moldova, Centre of Education . “Gaman Janos” and “Puskas Tivadar”, Sfîntu Gheorghe, district Covasna, Romania.
