(Over a three-year period) those who viewed the most sexual content on TV were about twice as likely to be involved in a pregnancy as those who saw the least.
. . . researchers calculated how often the teens saw characters kissing, touching, having sex, and discussing past or future sexual activity.
. . . About 25 percent of those who watched the most were involved in a pregnancy, compared with about 12 percent of those who watched the least. The researchers took into account other factors such as having only one parent, wanting to have a baby and engaging in other risky behaviors.
In every group, children who were exposed to more video game violence did become more aggressive over time than their peers who had less exposure. This was true even after the researchers took into account how aggressive the children were at the beginning of the study — a strong predictor of future bad behavior.
Children who watch violence “can internalize the message that the world is a hostile place and that acting aggressively is an OK way to deal with it,” says Dr. L. Rowell Huesmann. In addition, children can become desensitized to violence, he said.
Others say context matters: Are players using violence to defend virtue or hunt down people to kill?
