Our 20 subjects — registered voters who stated that they were open to choosing a candidate from either party next November — included 10 men and 10 women. In late summer, we asked them to answer a list of questions about their political preferences, then observed their brain activity for nearly an hour in the scanner at the Ahmanson Lovelace Brain Mapping Center at the University of California, Los Angeles. Afterward, each subject filled out a second questionnaire.

While in the scanner, the subjects viewed political pictures through a pair of special goggles; first a series of still photos of each candidate was presented in random order, then video excerpts from speeches. Then we showed them the set of still photos again. On the before and after questionnaires, subjects were asked to rate the candidates on the kind of 0-10 thermometer scale frequently used in polling, ranging from “very unfavorable” to “very favorable.”
