An important element in the professional development of the individual is professional selfdetermination.
It is important for a teenager to make his own choice, not the choice of his
surroundings. Identifying a predisposition to a particular profession will allow a person to decide
on her choice. We assume that it is possible to reveal the professional predisposition by studying
the psycho-physiological characteristics of a person, namely the frequency-specific characteristics
of the electroencephalogram of the brain. The paper analyzes the results of a pilot study aimed at
identifying professional predispositions through psychophysiological studies of the professional
skills and aptitudes of students in various fields; statistically significant correlations between
electrophysiological indicators, neuropsychological parameters and professional development are
described. Based on a theoretical analysis of the work on this topic, the idea arose of the need to
conduct a full-scale study on the study of the psycho-physiological characteristics of a person in
various professional fields and with different levels of academic achievement.
The study analyzed the indicators of alpha, beta, theta and delta rhythms during the subjects
performing tasks (exam, laboratory work, etc.), which are based on the GEF. The study revealed the
possibility of studying the professional inclinations and inclinations of students in various fields of
professional activity using a single methodology, which is based on the study of the EEG activity of
the brain.
