An ERP Study On The Impact Of Different Motivation And Arousal Emotional Images On Inhibition Of Return

Inhibition of return has always been the focus of the selective attention.There are many researches on inhibition of return and sports,but most researches on inhibition of return are only focused on behavioral research and less on ERP.A large number of studies have shown that inhibition of return is an important aspect of the selective attention and has an important relationship with human cognitive processing.In this study,four different types of emotional images(high motivation and high arousal,high motivation and low arousal,low motivation and high arousal,low motivation and low arousal)are used as clues and the cue paradigm are used to study the inhibition of return.Formal experimental subjects for 29 sports college students.The behavioral results show that: the main effect of clues is significant,the response of subjects under effective cues is longer than that under clues,indicating Back-inhibition is a blind mechanism,independent of the emotional impact of cues.From the ERP results,(1)From the latency period,there is no significant difference in the latency of P1 induced by the four types of emotional pictures;(2)The emotional picture of high motivation and high arousal type is induced N1 had the longest incubation period and the low N1 motivation induced by low motivation and low arousal motivation;(3)The N2 latency induced by high motivation and high arousal type pictures and N2 motivation induced by high motivation and low arousal pictures were the shortest.Low motivation and high arousal type of pictures induced by the longest P3 latency,high motivation and low arousal type of pictures induced by the shortest P3 latency.(4)From the average amplitude,there is no significant difference in the mean amplitude of P1 induced by the four types of emotional images;the average amplitude of N1 in high-motivation and high-awakening emotional images is lower than that of high motivation and low arousal;Motivation Arousal type images induced the highest average amplitude of P3,low motivation low arousal type of images induced P3 average amplitude was the lowest.
