Researchers from the University of California, Berkeley, Stanford University and Johns Hopkins University scanned the brains of more than three dozen politically left- and right-leaning adults as they viewed short videos involving hot-button immigration policies, such as the building of the U.S.-Mexico border wall, and the granting of protections for undocumented immigrants under the federal Deferred Action for Childhood Arrivals (DACA) program.

Their findings, published today in the Proceedings of the National Academy of Sciences, show that liberals and conservatives respond differently to the same videos, especially when the content being viewed contains vocabulary that frequently pops up in political campaign messaging.
