Studies of psychophysiological processes, in particular neurophysiological and somatic-vegetative mechanisms for human in-tegration into a joint group activities are relevant and contemporary in the new field of neurosciences – neuro-socio-ethology. In this regard, the purpose of the study – to develop computer models and protocols for investigation, and approbation of software and hardware systems for the analysis of a set of indicators (from the psychological to the neurophysiological) during the joint activities of the subjects. Psychophysiological examination was conducted involving 20 healthy subjects volunteers of both sexes (6 men, 14 women, 20-73 years). Protocols had been developed for surveys of the individual qualities of the subjects, which included several blocks: 1 – psychological surveys (tests on personal and situational anxiety, Cattell questionnaire); 2 – identification of individual indicators when performing visual-motor test "Shooter" (the learning rate, performance, riskiness, stability, resistance to processes of mismatch after errors, adaptability to novelty, level of claims and the adequacy of self-evaluation of rezults). The third stage consisted in training the subject to control the height of the "Column", which dynamically changed depending on the electromyographic (EMG) signal recorded by the telemetric sensor "Kolibri" from the flexors or extensors of his hand ("BOS-kinesis", LLC "Neurotech", Taganrog , The Russian Federation). The color of the column reflected the achieved result – the retention in the specified in the threshold range: red – the result is not achieved, the yellow is close to the threshold, the green is the achievement of the result. At the next stage, pairs of subjects were examined in the course of joint activities that included opposite types of relationships. In case of competitive activity of 2 subjects, the same model was used in the modification of the 2 columns submitted in parallel, but with the instruction and motivation of participants to compete in the effectiveness of achieving their own results. To study the psychophysiological processes in the cooperative activity, two participants were required to maintain the height of one column in the established corridor due to the agreed muscular contractions of the hands. Ensuring achievement of the overall result was achieved by the dynamics of the summing resultant of their 2 EMG signals.
