Outline of Final Research Achievements

We test the Spiral of Silence Theory about internet use in Japanese internet society. We looked at Twitter and analyzed whether the Spiral of Silence Theory would hold for it. Twitter’s speed and scope of information dissemination is fast and extremely wide ranging. For these reasons, Twitter is an appropriate field for analyzing the influences of the internet on the formation of public opinion. By integrating social investigation and behavioral log analysis, we test a model that incorporates an individual’s attitudes (measured via a questionnaire) and an individual’s communication network structure and actual communication behavior (measured via behavior log analysis).
