Studies have observed that watching violent television can lead to more aggressive behavior. In the effects of "The Mighty Morphin Power Rangers" children were significantly more aggressive after watching power rangers. This is referred to the "Bobo Doll" experiment that showed that children imitate aggressive actions of a model. Therefore after watching the power rangers fight of evil young children will then want to fight and pretend that they are Power Rangers.
This discovery is important because young children in general spend the majority of their free time engrossed in their favorite television show. Since the more violent and action packed shows are often more popular, television for children is often violent, exciting and action packed. My younger brother spends the majority of his time watching Nickelodeon in which the shows including Avatar are based on fights and battles between good and evil. After he watches these shows I observe that he is more easily agitated and aggressive. Since adolescence is the time period in which children learn their values I think that television should focus on instilling good morals in children instead of an aggressive attitude.
I think the solution to this problem would be restriction on television by parents. Parents know their children the best and they should be able to decide how to raise them. Although they should have this power it would be ideal if television shows encouraged kindness and good social skills.
