Some people believe that TV has more positive effects more than negative effects on children's behavior since there is a countless number of educational materials in a TV and movie, while other people think differently.
If I were asked to choose, I would say that the negative effects made from TV influence children's behavior more significantly than the positive effects do for the following two reasons.
First, children usually more sensitively react to vicious materials than a educational material.
To be specific, there is not only educational material in the TV, but there are also some erotic and cruel type's program in the TV.
And usually the children more easily delicately react to the vicious materials since these kinds of things are usually excluded by their parents.
Also, when people do something banned, they get so excited.
Therefore, even though the TV contains some helpful programs for children to learn norms, they will negatively affect children's behavior.
For example, according to an experiment taken by the NewYork times, they found that children usually get more influenced with vicious material than educational material.
They assigned children to watch two movies while observing them.
The first movie contained a lot of cruel scenes like a killing zombie and a blood while the second movie showed only an educational information about a history.
During watching the first movie, the kid seemed to get so excited and after this time, some children mimicked the behavior shown in the first movie.
Second, the TV and movie make children easily be addictive in them.
Since watching the TV and movie are so handy tools for children to easily escape from an awful reality, while their parents usually force them to study.
Then, this TV addiction is not only going to weaken their body, but it also will make the children get some nocturnal lifestyle.
So, since the TV and movie give some disadvantages by causing them to get addictive in the TV and movie, the TV and movie have so negative effects.
For example, when I was a 9, I spent most of my whole days by watching some Japanese animation and took asleep for just two hours.
Now I think that this is a reason why I was lacking of stamina compared to other peers and got some nocturnal lifestyle.
To sum up, the TV and movie show some erotic and vicious material to the children and it causes them to get some bad habits, even though there are also educational programs in the TV and movie.
Also, the TV and movie easily make the children addictive in them.
In this regard, I firmly believe that the negative effects of the TV and movie have more impact on children's behavior than their positive effects do.
