The Relationship Between Event-based Prospective Memory And Both Of Age And Ongoing Tasks

In recent years,many psychologists pay more attention to the research of prospective memory.Here,using ERP technique,prospective memory studies are presented which investigate the characteristicof people’s prospective memory ability in different cue style and different loads of ongoing task.To verifiesthe influence of cue style,load of ongoing task and age on prospective memory and to explore theprocessing mechanism and the characteristic of prospective memory with different task setting.So as toinvestigate the effect of prospective memory in different cue style,load of ongoing task and age.32college students from Henan University were assigned randomly to two groups,32studentfrom Zhoukou city was assigned randomly to two groups,which includs two experimental groups,focalgroup and nonfocul group.Load of ongoing task is in-subject variable,cue style is between-subjectvariable.In experiment the focal cues appears directly in the instructions, the nonfocal cues appears thatbelong to the category in the instructions.To inspect in different types of perspective cues,under thedifferent load of ongoing task, college students, high school students’ behavior and EEG of prospectivememory.Through the study, the following conclusions.First,as individuals are mature,the ability of prospective memory is improved.The load ofongoing task does not affect the completion of prospective memory task.The performance in prospectivememory under focal cue is better.Second,when the load of ongoing task increases, the amplitude of the P200decreases and theincubation period is shorter. As individuals’frontal lobe function is mature, the amplitude of the P200increases. The impact of cue style on amplitude of P200was not significant.Third,when the load of ongoing task increases, the amplitude of the N300increases,the agedifference of N300appears in focal cue,the amplitude of junior is greater.Forth,on the amplitude of prospective positive,the affect of the load of ongoing task is significantin college students,the load of the ongoing task does not affect the amplitude of high school students.Fifth,on the amplitude of N300, the impact of the cue style is more significant when the ongoing task is perceptual processing. In college students the impact of the cue style on the amplitude of N300ismore significant,but not in high school students.Sixth,when the ongoing task is semantic processing,the impact of the cue style on the amplitudeof prospective positivity is more significant,the amplitude of prospective positivity is more positive underfocal cue.when the ongoing task is perceptual processing,The impact of the cue style on the amplitude ofprospective positivity is not significant.
