Lab | Teaching > Political Communication & Behavior Lab

The PCB Lab is focused on the intersection between political communication and political behavior. We study the nature of news and social media, and the effects that media have on our political decision-making. We rely on a range of social-scientific methods including surveys, lab- and survey-based experiments, automated content analysis, network analysis and psychophysiological studies.
