Introduction. Person cannot be in complete control of his or her environment, he or she may be prone to unexpected decisions. Experimental research method refers to the basic research methods in psychology. At the same time, experimental research in itself is a complex system that reveals specific manifestations of synergetic orientation.Purpose. The purpose of this experimental study was to analyze the impact of environmental stimuli on the manifestations of self-esteem and risk-taking of adolescents. Hypothetically, we assume that watching videos with different content components has an impact on a person's propensity to take risks: videos with dynamic and intense content will increase a person's propensity to risk and reduce individual self-esteem, videos with calm content, on the contrary, determine risk and increased self-esteem of adolescents.Methods. The task of our experiment was to determine the impact of watching videos with different content on the risk appetite and self-esteem of adolescents. The essence of the experiment was to simulate risky life situations, which cannot be achieved only by testing. In parallel, the relationship between an individual's self-esteem and risk behaviour. In the course of the experiment, the methods of diagnostics of the degree of readiness for risk of Schubert and "Self-assessment of personality" were used.

Thus, the experimental study is a synergetic system, in the process of its implementation there are transformations of the initial hypothetical assumptions, the expansion of the study area. The experiment allows not only to collect and analyze data, as in conventional testing, but also has an impact on the subjects, which, in turn, allowed to stimulate a sense of risk, ie better analyze the condition and risk propensity of student youth.Thus, the assumption of the impact of watching videos with different content on the individual's propensity to risk has not been confirmed. Despite the lack of statistically significant differences between boys and girls when watching intense videos, there are tendentious weighted group differences in risk propensity by gender.Conclusion. It was found that intense environmental influences can reduce the overall self-esteem, self-esteem, and extraversion in adolescents. The experimental study revealed the prospect of further studies of the hypothesis that young people are more likely to experience changes in self-esteem under the influence of external stimuli, but these assumptions are the prospect of further research.
