In our research, we focus on political attitudes, public opinion, and political behavior, especially voting behavior, in modern democracies. Pursuing a micro-analytical approach, we consider attitudes and behavior as resulting from political information processing at the individual level. Political information processing is affected by individual characteristics as well as by communication contexts and institutional settings. In addressing issues in political behavior, political attitudes, and public opinion, we thus draw on concepts and theories from political psychology and political communication. Since substantive conclusions depend on methodological choices, issues in political methodology are also important for both our research and teaching.
