In the new article “The Contexts of Political Participation: The Communication Mediation Model Under Varying Structural Conditions of the Public Sphere” in the International Journal of Press/Politics, the International Communication Research Group examines the communication mediation model in 17 countries with varying levels of political freedom and digital infrastructure. Results show how these factors condition voting and protest behaviors.
Abstract: This study explores how emerging media platforms (i.e., social media and messaging apps) contribute to affective political polarization. We rely on cross-national data (USA and Japan), which allows us to explore the broader implications of how emerging media platforms contribute to political polarization in different cultural contexts. The results are very consistent; social media news use is positively related to affective polarization while messaging apps are negatively related in the USA and Japan. In addition, in the USA, the association of messaging app news and affective polarization is amplified by partisanship strength.
