The Influence Of Varying SOAs Of Endogenous And Exogenous Attention On The Numerical Distance Effect From The Study Of ERP

People in daily life figures play an important role in understanding the world,and numerical distance effect(numerical distance effect)has been used as digital processing(number processing)one of the hot spots.At present,the study of digital has gradually from a single digital cognitive task to complex multitasking.On the basis of existing research,this paper explores how the change of SOAs affects the digital distance effect under the premise of endogenous and exogenous attention.The key point is that the SOAs change to the digital distance Differences in the intrinsic mechanism of effect.The task of all subjects in the experiment is the same,the task of the experimenter is to determine the size of the digital target.The difference between research and research is that the former is an endogenous cue(ie,a central cue),which is an extrinsic cue(ie,a peripheral cue),both of which have a cue prompt and an invalid cue prompt(ie 75 % Cue prompt valid / 25% is invalid for clue hint).The results show that:(1)Under the premise of endogenous attention,there is a significant difference in the validity of the clue suggested at 300 and 700 ms,and the validity of the clue is not significant when the SOAs is 100 ms.At the level of each SOAs,whether there is a significant difference in the distance between the clue cue and the clue hints,and the clue prompt is effective,the numerical distance effect is stronger than the clue prompt is invalid.(2)Under the premise of exogenous attention,there are significant differences in the validity of the cues on the SOAs level,and there is a significant difference in the digital distance effect at each SOAs level,that is,whether the clue is valid or the clue is invalid.There is a significant difference,and in the SOA 300 ms,the digital distance effect of the strongest difference.EEG results were:(1)endogenous attention under the premise that the SOAs for the 500 ms clue prompted ineffective P1 component found significant difference between the digital distance effect;in the SOAs for 100 ms and 700 ms cue tips effective and SOAs for 500 ms Of the clues suggest that the difference in the N2 component found significant difference in the digital distance effect;SOAs for the 300 cues suggest that the effective P3 component also found significant differences in the digital distance effect.(2)Exogenous attention to the premise that the SOAs for the 300 ms clue are not valid and the SOAs are valid for the 500 ms clue that the N1 component is found to have significant digital distance effects;the SOAs are 100 ms clues that are not valid and the SOAs are 500 ms clues Suggesting that a significant digital distance effect is found on the P2 component under the effective effect;SOAs are effective for the 300 m and 700 ms cue tips and the SOas is 100 ms for the clue that the invalid N2 component is found to have significant digital distance effects;SOAs are 100 ms and 700 ms Suggesting that a significant digital distance effect was found on the P3 component that was not valid.
