Abstract/Summary Recent studies have captured the effect of reward on attention and liken it to a third form of attentional capture beyond that of the endogenous and exogenous accounts. However, this literature fails to identify whether or not the reward learning is attached to the underlying cognitive mechanisms of the training task (Context Hypothesis) or to the feature (color, shape etc.) that has the high reward association (Feature Hypothesis). The current study aimed to address this flaw by using a Visual Search paradigm in the reward association training phase and then a Visual Short-Term Memory paradigm in the testing phase of the study. The results of Experiment 1 supported the Context Hypothesis with no effect of reward training being found. The methodological flaws of Experiment 1 were addressed in Experiment 2. Experiment 2 found a significant effect of High-Value colour for False Alarm rate but not for Hit rate. The differentiation of the HV colour in the testing phase in this form lends support to the Feature Account of reward driven attention.
