Rewarding attention to a particular color results in a subsequent strong capture of attention by that color. Punishing attention to a color might lead to suppression of attention to that color. Alternatively, a punished color might capture attention, if features associated with consequence capture attention, regardless of the valence of the consequence. Finally, it is possible that only rewards will drive the capture of attention. To test these possibilities we first trained participants to search for a target that could be one of three possible colors. One color was associated with a modest financial gain, the other was associated with a modest financial loss, and the third had no payouts. In a subsequent search task, the rewarded color showed strong capture and both the punished and no-payout color had equivalent levels of weak, but significant, capture. These results suggest that being a frequent target during the training phase causes subsequent attentional capture. Associating a color with a gain further increased capture above and beyond this effect, but associating a color with a loss did not increase or decrease capture beyond the frequent target effect. However, during the training task people correctly responded to rewarded targets more frequently than the other two target types, raising the possibility that the effects were due to selection history rather than reward contingencies. In a follow-up, during the training task an algorithm was used to dynamically alter the number of trials in each condition to ensure equal numbers of selections for each target type. Despite equating selection history during training, during test we found attention capture for the rewarded but not the punished color. Our results suggest that punishment does not engage the mechanism responsible for the value-driven capture effect, and these effects are not due to different selection histories.
