[P.K. Anokhin's theory of functional systems in the study of psychophysiological parameters of students' efficacious activity].

Psychophysiological characteristics of students' efficacious educational activity were studied in the context of P. K. Anokhin's theory of functional systems. Autonomic functions and dysfunctions and energy expenditures were measured in students during their daily educational activity and after oral examinations. Their physiological characteristics and personality traits were shown to be related to the results achieved by the students--to their marks got at examinations and to their reaction of satisfaction/dissatisfaction with their marks. The students who were satisfied with marks showed increased anxiety, vegetative vascular dystonia, and profound changes in energy expenditures and autonomic functions, i.e. a high physiological price for educational success. The students who failed displayed low physiological expenditures manifested by extraversion and were apparently healthy.
