Vztah spokojenosti života a času tráveného na sociální síti

The bachelor thesis focuses on the phenomenon of social networks. It analyzes the reasons and side effects of their popularity among young people and describes in brief the best known world's and Czech social networks. From the psychological point of view, it deals with internet communication and differences between the virtual and real environment. More deeply it explores the loss of inhibitions in the virtual one, its causes and manifestations. Further the theoretical part concentrates in particular on the negatives of the use of social networks and, in general, of Internet communication and personal computers. Its reader will be familiarized with numerous psychological risks for users. The main part of the thesis is related to the questionnaire survey that has been carried out, inquiring mainly the amount of time spent by young people on social networks, their satisfaction with their life and at last, whether there exists any dependence between these two variables. It also examines, how much and for which purpose these networks are used by them. The survey data have been processed by statistical methods, namely by the analysis of variance (ANOVA), by means of which the initial hypothesis, that people who are more satisfied with their lives spend less time on social networks than the dissatisfied ones, for whom the virtual environment can be a getaway from their problems, could be proved true.
