Mean skin conductance change (in microsiemens) as a function of political temperament (left versus right) and political image type (appetitive versus aversive). Triangles with solid line, right-of-centre; squares with solid line, left-of-centre.

First fixation time values (in milliseconds) as a function of image type and trial type for left-of-centre (square with solid line) and right-of-centre participants (triangle with solid line). (a) Represents first fixation time to image types on trials in which three appetitive and one aversive image are presented (predominantly appetitive), whereas (b) represents first fixation time to image types on trials in which one appetitive and three aversive images are presented (predominantly aversive). Note that unlike dwell time—in which large values represent a greater attentional bias towards an image—small first fixation time values represent a greater attentional bias towards an image given that the lower the value, the faster the image was fixated.

Mean dwell time values (in milliseconds) as a function of image type and trial type for left-of-centre and right-of-centre participants. (a) Represents dwell time on trials in which three appetitive and one aversive image are presented (predominantly appetitive), whereas (b) represents dwell time on trials in which one appetitive and three aversive images are presented (predominantly aversive). Note that the values reported are the average dwell time for each individual image, so on a trial with three appetitive images, the total dwell time for all appetitive stimuli would be the reported number multiplied by 3.
