Irrelevant task suppresses the N170 of automatic attention allocation to fearful faces

Abstract Recent researches have provided evidence that stimulus-driven attentional bias for threats can be modulated by top-down goals. However, it is highlight essential to indicate whether and to what extent the top-down goals can affect the early stage of attention processing and its early neural...

description	Abstract Recent researches have provided evidence that stimulus-driven attentional bias for threats can be modulated by top-down goals.
