概要	Emotion appraisal in politics studies how distinct emotions, anxiety, anger, enthusiasm, and others, arise from cognitive appraisals of political events and in turn shape attention, information seeking, persuasion, and participation. It combines appraisal theory with affective intelligence theory (Marcus, Neuman and MacKuen, 2000) and Brader's (2006) work on emotional campaign appeals, typically measured through experiments and surveys that elicit and analyze discrete emotional responses.	Affective polarization measurement quantifies the gap between how positively people feel toward their own political party (the in-party) and how negatively they feel toward the opposing party (the out-party). Iyengar, Sood and Lelkes (2012) showed that this affective divide has grown sharply even where issue positions have not, reframing polarization as a social-identity phenomenon of partisan like and dislike rather than ideological distance.
