Most of us have mobiles and in Australia alone we send millions of texts a month. But little is yet known about the psychological effects of the mobile phone. Is it changing the way we relate to each other and if so, is it for better or worse? How can psychologists research these questions? This program examines researching young people's use of mobile phones with three different non-experimental methods. We see the research taking place which is inter-cut with the researchers explaining their methods and findings, young people's views on mobiles and expert analysis. The program is divided into three linked but self-standing sections: Questionnaire Surveys, Interviews, and Naturalistic Observation.
