摘要:The objective of this paper is to try to identify the specificity and fre quency of cyber-agression as a form of problem behaviour characteristic for the contemporary youth known as Generation Y. Analysis of the results of research conducted among schoolchildren aged 15–16 indicates that cyber-agression is a common phenomenon in the group. It raises the need for reconstruction and re-evaluation of practices and standards developed to date and implemented to address the problematic behaviour of young people through the global net_x0002_work. In the paper,proposals for solutions in this area are presented,which can be used to create future prevention programs aimed at constructive online behaviour and foster rational choice-making regarding the use of the Internet and modern media.
