Emotions play an important role in explaining why news framing has effects on opinions about immigration. Yet, our knowledge regarding which emotions are relevant for different types of news frames is limited. This survey experiment (N = 715) determines to what extent positive and negative emotions mediate framing effects about immigration, and whether mediation depends on the type of frame at stake. We exposed participants to one of four preestablished frames: the emancipation, multicultural, assimilation, or victimization frame. Results show that the emancipation and multicultural frames cause the most emotional response. Positive emotions function as mediators of framing effects on immigration opinions.
