As a primordial means of communication, language plays an essential role in shaping people’s decision making. Professional communicators stand out because they understand how to employ effective linguistic strategies to motivate individuals to take desirable actions and identify the similar designs from others. Drawing on theories of linguistics, communication studies, and psychology, this course introduces various theoretical frameworks that explain the intrinsic correspondence between subtle language features and critical decision-making in a range of professional contexts. Through interactive lectures, case studies, and group projects, students will employ theories to critically examine real-world decision-making issues and design effective intervention strategies to create more socially desirable outcomes.
