负性分心刺激对注意瞬脱的影响

Effect of Negative Distracting Stimuli on Attentional Transience

摘要: 目的：本实验通过改变不同情绪类型的分心图片，探讨负性情绪分心刺激对注意瞬脱的影响。方法：本实验采用经典的快速序列视觉呈现范式，以负性情绪图片和中性图片作为分心物，考察对大学生注意瞬脱的影响。结果：分心物类型对于T2正确率的主效应显著(p < 0.001)，负性图片的分心物能引发更显著的注意瞬脱现象；目标刺激间的时间间隔对于T2正确率的主效应显著(p < 0.001)，当时间间隔为300 ms时，注意瞬脱现象显著，当时间间隔为600 ms时，仍然存在注意瞬脱的现象；分心物类型和时间间隔的交互作用不显著。结论：(1) 分心物的性质对注意瞬脱效应有影响。(2) 不同的时间间隔可以影响大学生的注意瞬脱效应。

Abstract: Objective: To explore the effect of negative emotional distraction on attentional blink by changing the distracted pictures of different emotional types. Methods: Using the classic fast sequence visual presentation paradigm, negative emotional pictures and neutral pictures as distractors, this experiment investigated the effects of negative emotional pictures and neutral pictures on College Students’ attentional blink. Results: the main effect of distractor type on T2 accuracy was significant (p < 0.001). Distractors in negative pictures could induce more significant attentional blink; The main effect of time interval between target stimuli on T2 accuracy was significant (p < 0.001). When the time interval was 300 ms, attentional blink was significant. When the time interval was 600ms, attentional blink still existed; The interaction between distractor type and time interval was not significant. Conclusion: (1) the nature of distractors has an effect on attentional blink. (2) Different time intervals can affect the attentional blink effect of college students.
