According to a study that monitored brain activity while participants watched 40 minutes of political ads and debate clips from the presidential candidates, Donald Trump is unique in his ability to keep the brain engaged. While Hillary Clinton could only hold attention for so long, Trump kept both attention and emotional arousal high throughout the viewing session. This pattern of activity was seen even when Trump made remarks that individuals didn’t necessarily agree with. His showmanship and simple language clearly resonate with some at a visceral level.
