The Influence Of Reward To Facilitation And Inhibition Effect Of Exogenous Spatial Attention

It is thought that reward-induced motivation influences endogenous attention process to facilitate behavioral performance, whether it can affect exogenous attention process or not remains to be further research. Existing related studies have shown that rewards can influence early facilitation of exogenous spatial attention, but cannot affect the late inhibition of return. But the results of these studies may be disturbed by the rewards history. In this study, we investigated the effect of reward-induced motivation on exogenous attention process. By controlling the influence of rewards history, we found that rewards not only can reduce early facilitation effect of exogenous spatial attention, but also can reduce the late inhibition of return. Which clarified that rewards can influence early facilitation of exogenous spatial attention, but also can affect the late inhibition of return. This accords with the attention resource theory, it also illustrates that the facilitation and inhibition effect can be adjusted by top-down attention.
