The Effect of Reward Information on Perceptual Decision-Making
Decision making can be treated as a two-step process involving sensory information and valuation of various options. However, the integration of value and sensory information at a neural level is still unclear. We used electroencephalography (EEG) to investigate the effect of reward information on perceptual decision making using two- alternative discriminating task. The reward information was signalled before the appearance of the stimuli. Our findings suggest that economic value acts as a top-down influence early in the decision epoch possibly shifting the evaluation criteria to a more favourable outcome.
