Instances of stress and depression in the parents affect the child psychologically. This may result in their own eventual stress or depression, and aggression offers an outlet for their negative feelings.
The story narrated above of the frustrated mother and her four-year-old boy gives us another cause for aggressiveness in children. According to this mother, her child started becoming aggressive when he had to change schools. These changes from an environment he was used to one he was unfamiliar with could have caused the aggression, as the child’s emotions were affected by the change. This may have made him feel out of control resulting in a situation where he had to act out in order to restore the sense of balance. It may also have been a way of him attracting the attention of his ever-busy parents.
