Study of phase dynamics of psycho-physiological functions

This study is devoted to investigation of psycho-physiological functions of three nervous system departments (central, autonomic and somatic ones) for detecting periodic changes of their activity. In the study participated 566 people of both sexes, all of them were second-year students of St. Petersburg State University, Faculty of Psychology. Followed characteristics were measured: EEG figures (a-index, mean and dominant frequencies), blood pressure, breathing frequency and volume, heart rate frequency, lung vital volume, dynamometry, static and dynamic tremor. The investigation showed that all these figures change periodically, and the change period is equal one semester. It means that, firstly, the data of the investigation can be used for constructing of a new temperament diagnostic test (further the data can be used for constructing of other diagnostic tests). Secondly, the results of the investigation can be used for improvement of studying and professional activity process.
