In the last few decades, there seemed an increase rate of aggression among children. There are several forms of aggression including “instrumental aggression” which is intended to gain object or privilege, “hostile aggression”-inflicting intentional harm, “overt aggression” in which the child threatened or physically hurt the other person and “relational aggression” which involves threatening or damaging social relationships.

Aggressive children tend to believe that violence will be rewarded, and they use aggression to get what they want. They are more likely to believe that violent retaliation is acceptable: “It’s Ok to show people when you are mad” (Egan Monson & Perry, 1998). Insults, exclusion taunts etc. all are forms of relational aggression and sometimes called social aggression. Modelling plays an important role in expression of aggression. Children who grew up in homes where harsh punishment and family violence is present are more likely to use aggression to solve their own problems.

One very real source of aggressive model is found in television. In United States, 82% of TV programs have at least some violence. The rate of aggression in children programs is really high- an average of 32 violent acts per hour, with cartoons being the worst. And in over 70% of the violent scenes, the violence goes unpunished (Mediascope, 1996; Waters, 1993).

Both girls and boys take part in aggression, but after 2^nd or 3^rd grade, girls tend to be more social aggressive than boys. This may be because as girls, they are more aware of gender stereotypes; they push their overt aggression underground into verbal, not physical aggression- both to the victims and aggressor.

Relational aggressors can be viewed as even more problematic than a physical aggressor by teachers and other students (Berger 2003; Crick, Casa & Mosher,1997). As early as preschools, children with aggression should be diagnosed and treated so they can be well adjusted in society without having any serious problems.
