Psychophysiological basis of individual human behavioral reactions

The aim of the research: elucidation of autonomic dynamics (according to the electrical resistance of the skin) during functional load, taking into account the individual-typological properties of the nervous system and psychological qualities of the individual. Materials and methods. Determined the functional mobility of nervous processes (FMNP, the method of M. V. Makarenko), electrical resistance of the skin (polygraph study), psychological personality traits (16-factor personality questionnaire by Cattell). Results. The relationship between FMNP, individual parameters of skin galvanic response and some personality traits has been identified. The questions concerning the role of individual-typological properties of the nervous system in the development of autonomic reactivity, their connection with psychological personality traits, prediction of possible behavioural reactions and states are considered. Conclusions. It was found that individuals with high FMNP in terms of sensorimotor response, more likely to have a variant of behavioral response, which is characterized by maximum speed and accuracy of the task, low anxiety. However, there is a risk of overstrain of the autonomic nervous system (according to the indicators of the phase electrical resistance of the skin (ERS)). In the case of low levels of FMNP, a variant of behavioural response with relatively low task efficiency, slow autonomic regulatory processes and a tendency to experience is more common. We claim that FMNP is involved in creating a neurodynamic, autonomic and psychological basis for individual behaviour during sensorimotor response in emotionally stressful conditions. The identified differences can be useful for determining the optimal area of professional activity, settling interpersonal relationships in the team, predicting the limits of acceptable actions and human actions, assessing the likelihood of risks of personal responsibility, the degree of stress, and so o
