There is a common misconception in the video game world that playing too much can lead to poor academic performance. On the other hand, it may also be frowned upon in schools to use a cell phone
while in class. But all these stereotypes can be put aside because a research conducted by Michigan State University yielded that using mobile phones had no effect on educational results. The three-year study of roughly 12 year old students from 20 schools concluded that females used mobile phones more frequently than males. At the same time, there is no viable evidence that hints to poor performance in school. But the study used a sample source of younger teens rather than older ones. Thus, further research may need to be done for older age groups who might be engaged in devious behavior such as spreading gossip or rumors via texting.
