| Attention blink(AB)is a phenomenon found in the study of attention in the field of time.For a long time,most researchers only focus on the study in the field of space.Attention blink supplements the dimension of research,which makes the related research of attention more in-depth,more comprehensive and easier to reveal the essence of human consciousness.Attention blink is a common phenomenon of functional blindness,which is attributed to the resource bottleneck of cognitive system.Previous studies have explored the effects of distracted stimulation before target stimulation T1,T1+1 after target stimulation T1,and distracted stimulation after target stimulation T2 on the magnitude of attentional blink effect,but the effect of distracted stimulation between target stimulation T1 and target stimulation T2 does not include the effect of distracted stimulation at T+1 position after target stimulation T1.In order to explore the effect of this part of distracted stimulus on attentional blink effect,this study explored the effects of distracted stimuli on attentional blink effect at different time intervals by controlling the two types of distracted stimuli before target stimulus T2.In this study,Eprime 2.0program and ERP(event-related location technology)are used to collect and process data.The results showed that when target stimulus T2 was located in lag4,there was no significant difference in attentional blink between cue and non-cue conditions,nor was there significant difference in evoked P3 amplitude.When target stimulus T2 was located in lag12,there was significant difference in attentional blink between cue and non-cue conditions,and there was also significant difference in evoked P3 amplitude.The results show that there is no difference in the effects of clue distractors and non-clue distractors on attention blink during the period of attention blink,which supports the theory of temporary out-of-control of attention and the theory of delayed engagement of attention. |
