ABSTRACT
The growing reliance on social media as news platforms may lead to more passive news consumption but also offers greater potential for engaging in news. This study investigates the role of engagement with news content on Facebook and Twitter between news exposure and current events knowledge. An online survey (N = 400) tests the relationships between social media news seeking, incidental exposure to news on social media, engagement in shared news content, cognitive elaboration, and current events knowledge. The results show that both active seeking of and incidental exposure to news on both sites are linked to engagement, which is linked to greater cognitive elaboration about the content. Furthermore, engagement mediates the relationship between both types of news exposure and cognitive elaboration. However, engagement and elaboration are not related to knowledge. These results indicate that the key role of social media in news content is not knowledge gain but the ability to engage users who may be passively receiving news on these sites. This study extends the cognitive mediation model of learning from the news in the context of current social media, with updated news consumption norms such as engagement with news on these sites, and incidental news exposure.4
