We live in a world of phenomena created by the human mind and by human experience, namely conflict, aggression, aggressiveness and violence. These phenomena are viewed as constructs of the mind, types of behaviour, particular experiences and emotional states, specific social interactions or even historical and political categories such as social movements, wars, angry social protests etc. The study explores the notions of aggression and violence and from an individual and a social perspective analyses their determinants in various environments in childhood, adolescence and adulthood. It is an attempt to join the global discussion on reaction conditions and key points that are connected with the risk of pathologization of the personality and its behaviour.

The sense of isolation and even rejection is well known to people from minority groups, including ethnic minorities. When it comes to children from ethnic minorities, the quick identification of the problem by teachers is of great importance. Anyway the problem must be realised not only by the educators and parents of the children of the minority, but also by the parents representing the cultural majority. The presented approach to the problem of ethnic minorities is not only oriented towards the social exclusion of the ethnic minorities, but tries to create a comprehensive strategy for dealing with "new faces of exclusion". The authors describe ethnic minorities in the countries of the Visegrad Group and try to define their cultural and national identity from the perspective of intercultural psychology.
