The chapter Growing Up in Virtual Reality Adolescents and the Internet, written by Zbyněk Vybíral, David Šmahel and Radana Divínová, concerns how adolescents use the Internet. The authors concentrate mainly on how adolescents behave in the Internet environment, how they use their virtual identities (personally and socially) and what the relationships are between their behaviour in the real and the virtual worlds. The Internet provides a space in which the adolescent can test opinions and attitudes, experiment with identity, and embark on the long journey to the complete formation of this identity. The research shows that the Internet significantly influences the way in which sexual content is presented and consumed, and how online sexuality is enabled by accessibility, availability, comfort and anonymity. The research uncovered a variety of inner motivations which can lead the individual to cybersex. It also became clear that the Internet has changed communication and provided a different rhythm, which is also reflected in deeper, experiential layers of the psyche. Communication in a virtual environment has specific features (multiplicity, superficiality, disinhibition, etc.) It seems that openness, positive disinhibition, activity, and the less censored need to confide can also be applied in the environment of online seminars and educational discussions.
