Going for the person with the ball is referred to as hostile aggression. Retaliatory aggression is carried out in response to another's aggression. Displaced aggression is when a child who has been the object of aggression reacts by striking out at something else. Aggression begets aggression. Aggressive acts toward children puts such actions in their realm of possibility.
Aggression is reinforced by aggressive parents, neighborhoods and schools, and in the media.
Also aggressive scripts imbed aggression and violence into a child's psyche. Children play out vertical aggression from parents and older siblings to horizontal relationships with peers. There's a difference in an aggressive child who simply goes for another's ball, and a child who goes for the ball because it represents regaining some of what he's never received. This pent up anger from lack of love and nurturing manifests itself in mean, hateful, hurtful and retaliative aggressive behavior. The aggressive child runs the risk of being rejected by his peer group and becoming an outcast.
