We use the fast sequence visual presentation paradigm(RSVP)task to conduct behavioral experiments and ERP EEG experiments.RSVP is a classic paradigm to study attention blink.We investigate the characteristics of emotional face recognition from the time dimension.The study is divided into two parts.The selected subjects are all college students,one is 2.(attention load: high,low)* 3(emotional face: positive,medium,negative)experimental design,in the RSVP paradigm,to explore the characteristics of positive and negative emotional face recognition under different conditions of high and low attention load;study two is 2(male,female)* 2(high,low)* 2(negative sex load: high,low)* 2(negative gender negative)Sexual emotion face: male and female mixed experiment design,in the RSVP paradigm,to explore the characteristics of negative emotional face recognition of men and women under different conditions of high and low attention load.Through the experimental study,the following conclusions are concluded:First,there were different degrees of attention transients in both positive and negative emotional faces,but the degree of attention transient under low attention load was lower than that of high load.Second,the correct recognition rate of heterosexual faces was significantly higher than that of the same sex,and there was a preference for heterosexual recognition.Third,in the RSVP experiment,the low attention load would induce greater EEG components N170 and VPP than the high attention load,indicating that N170 and VPP were influenced by the attentional resources.Fourth,face recognition showed that positive emotional faces evoked more EEG N170 than negative ones.Fifth,the correct rate of recognition of male negative emotional faces was lower than that of females.Sixth,the male negative emotional face recognition induced more negative brain wave N170,which was established at high and low attention load. |
