Advancing Understanding in News Information, Political Knowledge and Media Systems Research: Lab Study

As part of the Advancing Understanding of Media Effects on Political Knowledge project, we conducted a laboratory based experimental study to investigate some of the issues we identified in our secondary data analysis. It became obvious in our analysis that the measurement of exposure to media was critical and has been measured in many different ways. Therefore we tested various measures in an experimental study.
