This course examines the role that communication--and especially mediated communication--play in the social influence process. This course is organized around theoretical persuasive approaches to the study of attitudinal and behavioral change. It uses these theories as a basis for teaching about persuasive strategies that can be implemented to lead to changes in others' attitudes and behaviors--whether in the areas of media campaigns, marketing communication, advertising, or public relations. The course includes discussion of the strategies that "professional persuaders" use when peddling their ideas, products, services, and philosophies. (This course replaces CM409 in the curriculum. You should not take CM280 in addition to CM409 without having received permission from the department.)4 cr. 扫描电镜。
