Abstract: There is considerable controversy on the order of occurrence and strength of affective priming and semantic priming, and their relationship is independent or interacted is also at odds. The nature of these controversies related to the understanding of the relationship between these two basic systems of the human brain- emotional and cognitive systems. In order to clarify the controversy directly and systematically, present study plan to incorporate the affective priming and the semantic priming paradigms into the same behavioral and ERP experiment, with matching the factors that may affect the priming effect, like information intensity of prime, the degree of association between prime and target, etc.. And, to change the presentation duration of the prime, SOA and experimental tasks systematically, as well as to add in the variables of individual differences like age, gender, disciplines, cognitive style and susceptibility to emotion gradually. Hope that this design reveal the deep-seated processing characteristics of emotional information flow and semantic information flow, then enlighten the development of emotional and cognitive system's function and mechanism of human brain.

Key words: emotion, semantic, priming, event-related potentials
