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. In this talk I will discuss recent evidence that suggests that visual selection is determined by previous experience of rewards and punishment. We show attentional and oculomotor capture by stimuli that are associated with monetary reward. Moreover, stimuli associated with punishment (i.e., predicting electric shocks) also capture attention and eye movements indicating that not only reward but also threatening stimuli are prioritized by the visual system. Finally, we show that stimuli that merely signal the presence of reward (c.f., Pavlovian conditioning) have to ability to summon attention. The present study adds to the growing evidence that stimuli associated or signalling reward and punishment have the ability to exogenously capture spatial and non-spatial attention independent of task-set, goals and salience.2014-10-14
