| Exploring the relationship between memory and attention is a hot topic in the field of psychology.Prospective memory,as a kind of memory type,exists in the daily thinking activities of our brain and participates in the process of our cognitive activities.Attention is an ability to focus on specific stimuli.Attention blink is a common phenomenon of attention in the field of time.Due to the appearance of attention blink,transient "visual blindness" greatly affects athletes’ sports performance.This paper uses event-related techniques(ERPs)to explore the effect of prospective memory training on attention transients of college students at different sports levels,and selects46 college students at different sports levels as subjects.Behavioral data were analyzed by PM the correct rate of task in two-task experimental paradigm and RSVP rapid sequence response.EEG data were analyzed by CURRY8 software.The following conclusions were obtained:(1)The N100 amplitude induced by prospective memory training intervention is larger and the latent period is longer than that of the general group and the high level group,and the N100 latency of the high level group is significantly shorter than that of the general group and the general level group,which may be related to the exercise level,N100 belongs to the early component of the ERPs.The higher the exercise level,the faster the process of extracting intention and executing the action;(2)The results of EEG showed that the P300 effect was obvious in the subjects of the general group,the general level group and the high level group,left posterior occipital region(P3)and occipital region(O1)were more active in the high level group than those in the normal group.There was no significant difference in the central parietal Cz and prefrontal region.(3)After the intervention of prospective memory training,the attention transient level of college students in different sports groups decreased to a certain extent. |
