碩士 === 國立交通大學 === 資訊科學與工程研究所 === 96 === Dynamics of collective opinion is an important issue in social science. In the late 20th century, agent-based simulation was gradually adopted in researching opinion dynamics. By simulation, researchers attempted to find the rules behind some social phenomenon such as voting, revolution, fashion etc. In this thesis, I expand previous opinion dynamics models base on experiments and theories of social psychology. In my model, when agents exchange their opinions, they consider not only his own opinion but also his neighbor's reception, which is the so-called "normative social influence". In the previous models, agent is described by a single variable "opinion". In order to separate the effect of "public compliance" from the effect of "private acceptance", I propose the second variable attitude. In addition to basic opinion exchanging process, my model can simulate more complex social phenomenon such as pluralistic ignorance, revolution, minority influence, newcomer influence, mind control, media etc. Compared to previous models, this is the first thesis that based on experiments and theories to increase factuality and generality, which provide the social scientists a platform to observe and experiment.
