Time Course Of Emotional Noun Processing With Rapid Serial Visual Presentation

Nowadays,reading is becoming more and more important in our daily life.And rapid responses to emotional words have received a great deal of research interest.Our study employed rapid serial visual presentation to detect the time course of emotional noun processing.And we also detected the concreteness effects of emotional noun words.We performed a dual-task experiment,where subjects were required to judge whether a given number was odd or even,and the category into which each emotional noun fit.The result indicated that in terms of P1,we found that there was no negativity bias for emotional nouns.However,emotional nouns elicited larger amplitudes in the N170 component in the left hemisphere than did neutral nouns.Furthermore,positive,negative,and neutral words were different from each other in the late positive complex,indicating that in the third stage,even different emotions can be discerned.Moreover,the concreteness effects of emotional noun had no significant difference in this study.
