Abstract:
In last years aggressive behaviour have reached high level of manifestation. One of the most frequent types of aggressive behaviour is school harassment or bulling. There are different forms of bulling such as: teasing, threatening, spreading rumours, slander, exclusion from the group, social isolation, strikes, property damages, injury, refusal to fulfil a request, etc. Bulling has negative and harmful effects on child personality: diminishing wellbeing, sense of devaluation and low self-esteem. Extension and increased school harassment significantly affects emotional sphere of victim with the emergence of problems internalized behaviour: anxiety, behaviour, intense sense of loneliness and helplessness, school failure. School environment is important for how children create their perspective of expectations and beliefs about aggression and adapt their own behaviour and manage their emotion stability towards them.
