We describe the various methodological approaches to the measurement of today's global information and communication environment. It is shown that the image of the world of adolescents is influenced by diverse and divergent information flows, which are the source of communicative and cognitive needs, finding the ways of social and psychological adaptation, compensation, personal difficulties. This process creates special risks for adolescent socialization, adaptation, personal development. Based on the analysis of current research, we reveal the positive and negative aspects of the impact of modern information and communication technologies on the formation of adolescent identity. Online distribution of large volumes of information creates uncontrolled "cultural chaos" and blurs cultural identity, but also promotes the development of skills to design a virtual identity that can be seen as an integral part of the formation of the person in the new information society. We substantiate the direction of psycho-pedagogical support of socialization in the information society.
