Neuroelectrical Correlates of Trustworthiness and Dominance Judgments Related to the Observation of Political Candidates

Figure 1

Epochs of a typical trial. Each trial began with the image of a neutral face (1 s) to allow a washout of the neurophysiological variables. Afterwards, subjects were asked to express a judgment about the subsequent political candidates related to traits of trustworthiness, dominance, and preference of vote which were randomized among trials (3 s). Then, each single face of the political candidates racing for the same election appeared separately and in random order (1 s) among subjects and judgment. Finally, both faces were presented together for the decision stage (2 s). All stimuli were intermingled by a black screen (~[2, 3] s).
