Television can be a powerful influence in developing value systems and shaping behavior. Unfortunately, much of today's television programming is violent. Hundreds of studies of the effects of TV violence on children and teenagers have found that children may: "immune" or numb to the horror of violence accept violence as a way to solve problems the violence they observe on television; and with certain characters, victims and/or victimizers Extensive viewing of television violence by children causes greater aggressiveness. Sometimes, watching a single violent program can increase aggressiveness. Children who view shows in which violence is very realistic, frequently repeated or unpunished, are more likely to imitate what they see. Children with emotional, behavioral, learning or impulse control problems may be more easily influenced by TV violence. The impact of TV violence may be immediately evident in the child's behavior or may surface years later. Young people can even be affected when the family atmosphere shows no tendency toward TV violence is not the only cause of aggressive or violent behavior, it is clearly a significant factor. Parents can protect children from excessive TV violence in the following ways: attention to the programs their children are watching and watch some with them limits on the amount of time they spend with the television; consider removing the TV set from the child=s out that although the actor has not actually been hurt or killed, such violence in real life results in pain or death to let the children see shows known to be violent, and change the channel or turn off the TV set when offensive material comes on, with an explanation of what is wrong with the program of the violent episodes in front of the children, stressing the belief that such behavior is not the best way to resolve a problem offset peer pressure among friends and classmates, contact other parents and agree to enforce similar rules about the length of time and type of program the children may watch Parents can also use these measures to prevent harmful effects from television in other areas such as racial or sexual stereotyping. The amount of time children watch TV, regardless of content, should be moderated because it decreases time spent on more beneficial activities such as reading, playing with friends, and developing hobbies. If parents have serious difficulties setting limits, or have ongoing concerns about their child=s behavior, they should contact a child and adolescent psychiatrist for consultation and assistance.再给你推荐一个链接,很多内容都是关于你的论文主题的,希望可以帮到你:
