One of the main differences between the girls and the boys who took part in the research was the way in which they use the Internet. Unlike the girls, who use the Internet mainly to keep in touch with friends, the boys questioned in this survey tend to use the Internet for playing computer games. The girls differ from the boys in that they tend to spend more time keeping in touch with friends on the telephone or on social networking websites. Compared to the boys, the girls spend much more time chatting to friends on the telephone. On average the girls spend four hours a week chatting to friends on the phone. In contrast, very few of the boys spend more than five minutes a day talking to their friends in this way.
