Behavioral results from conditions where cars or people were the target of search. These results are presented for the sake of completeness; no core hypotheses are tested. In the stylized scene examples used here and in subsequent figures, high-magnitude reward is associated to cars; but as described in the body of the paper, this was counterbalanced across participants. A, Accuracy. As expected, responses to high-reward targets were more accurate in all conditions. B, Reaction times. Surprisingly, participants were faster to respond to targets presented in scenes that also contained an example of the localized distractor. This may reflect a qualitative difference in the images; scenes containing only one localized category type happened to be characterized by smaller, harder-to-find target examples. Data collected from presentation of these scenes were not used to test the core study hypothesis regarding the capture of attention to reward-associated stimuli.
