Background. The paper presents an innovative quantitative method for assessing neuropsychic fatigue based on the entropy approach. The relevance of the work is connected with the need to determine the neuropsychic state and resistance to stress in different conditions of human activity. This approach is consistent with the trends of modern psychology research on self-organization in the aspect of identifying the processes that underly the stress response during overcoming physical and central fatigue. The proposed method includes the formula of conditional deterministic entropy, tools of nonequilibrium thermodynamics in its information interpretation (I. Prigogine’s theorem on the minimum of entropy production).
Objective. The approbation results of the criterion estimates of neuropsychic stability for the prediction of motor-motor capabilities, behaviour and state of the individual are shown.
Background. The study of students and athletes (71 boys and 72 girls, average age -20- + 3 years) was conducted based on the data provided by the Biological Faculty of Moscow Lomonosow State University. The approbation of the method carried out on the basis of the data of psycho-physiological indicators (tapping test) allowed to assess the stability of the neuropsychic state of athletes. Results. The data confirmed the validity of the method and made it possible to identify stable and unstable states associated with the growth of neuropsychic stress that may result in central fatigue.
Conclusion. The regularities revealed in the experimental samples do not only correspond to the data of the tapping test technique, but also show more accurate and qualitatively meaningful assessments of the neuropsychic stress and the state of the system as a whole. The approach makes it possible to create a device for monitoring neuropsychic stress, i.e. «Halter tapping», and also allows to make similar assessments of sports teams in the process of training, for example, for game sports.
The paper presents the analysis of psycho-emotional state estimation, which is based on the facial feedback monitoring. The myographic research data revealed qualitative and quantitative singularities of epileptics on the range of basal emotion indicators which have been received on the matrix method way basis and model of quality diagnostics.
For the calibration method the study involved healthy subjects. Beforehand myographic cards were developed to measure the tone of facial muscles during the trial of six basal emotions. The experiment was arranged in such a way as to reflect the work of reverse afferentation emotions. Ahe amplitude-frequency characteristics of the samples and emotional reactions of involuntary reactions were identical. Therefore samples of complementary development of natural emotions were tried: the first test stage included efferent synthesis, the second stage used afferent synthesis.
Defining features of emotional response was carried out on the basis of the model of quality diagnostics of emotions. The chiral effects were identified: mimic pattern emotions in both samples. This effect allowed to separate violations of the personal response from the specific pattern, which blocks the effects of restrictions and other emotions. The matrix method allowed to produce quantitative estimates of mental and emotional state on the basis of instrumental measurements of basal emotions. In the group of epileptics, on the facial expression level emotional blocks are identified which are connected with ceral effects (repented characteristic deviation of emotional patterns in the two probes).
Additionally differences on quantitative estimations between the epileptics reactions and healthy individuals are revealed.
