Classic models of attentional control assert a dichotomy between top-down and bottom-up control, with the former determined by current selection goals and the latter determined by physical salience. In the present presentation, I will argue that this theoretical dichotomy is inadequate to explain a number of cases in which neither current goals nor physical salience can account for strong selection biases. I will argue that the salience map that drives automatic selection is not only determined by raw physical salience of the objects in the environment but also by the way these objects are shaped by selection history. I will provide evidence that priming (feature and reward priming) sharpens the cortical representation of these objects such that these objects appear to be more salient above and beyond their physical salience. I will demonstrate that these type of history effects are not under volitional control: it occurs even if observers try to volitionally prepare for something else. In other words, looking at red prepares our brain for things that are red even if we volitionally try to prepare for green.
