摘要

背景:本研究旨在探讨短暂性注意瞬变(AB)对临时应激情境的影响,以揭示创伤后情绪与注意之间的关系。方法:参与者是57名大学生,随机分为实验组(n=30)和对照组(n=27),实验组观看了描述灾难的新闻视频,对照组不看新闻视频。接下来是两组的快速连续视觉呈现(RSVP)任务。实验组和对照组在T1为新闻威胁刺激时出现AB;T1和T2的呈现间隔越短,AB越强。另一方面,当T1呈现新闻中性刺激时,组间AB模式发生变化。在T1时,无论呈现给对照组的是什么类型的单词,都出现了AB型;而实验组只有在T1中出现新闻中性词时才会出现AB模式。结果:当T1为创伤性刺激时,AB出现。然而,当T1是条件创伤刺激时,AB模式根据参与者是否观看灾难视频而变化。结论:我们的研究结果扩展了现有的研究,证实了AB在创伤相关的中性刺激和创伤刺激中的作用。

The Effect of Threatening Stimuli on Attentional Blink
Background: This study aimed to identify the effect of momentary Attentional Blink (AB) in temporarily stressful situations to reveal the relationship between emotion and attention after a traumatic experience. Methods: Participants were 57 college students randomly assigned to either an experimental group (n=30) that watched news videos depicting disasters or a control group (n=27) that did not watch them. This was followed by the Rapid Serial Visual Presentation (RSVP) task for both groups. AB appeared when T1 was a news threat stimulus for the experimental and control group; the shorter the presentation interval between T1 and T2, the stronger the AB. On the other hand, when news-neutral stimuli were presented in T1, the AB pattern between the groups changed. The AB pattern appeared regardless of the type of word presented to the control group in T1; however, in the experimental group, the AB pattern appeared only when the news-neutral word was presented in T1. Results: The results suggest that AB appears when T1 is a traumatic stimulus. However, when T1 is a conditioned traumatic stimulus, the AB pattern varies depending on whether the participant watched the disaster video. Conclusions: Our results expand on existing studies by confirming the AB effect in trauma-related neutral stimuli and trauma stimuli.

期刊介绍: The journal Stress aims to provide scientists involved in stress research with the possibility of reading a more integrated view of the field. Peer reviewed papers, invited reviews and short communications will deal with interdisciplinary aspects of stress in terms of: the mechanisms of stressful stimulation, including within and between individuals; the physiological and behavioural responses to stress, and their regulation, in both the short and long term; adaptive mechanisms, coping strategies and the pathological consequences of stress. Stress will publish the latest developments in physiology, neurobiology, molecular biology, genetics research, immunology, and behavioural studies as they impact on the understanding of stress and its adverse consequences and their amelioration. Specific approaches may include transgenic/knockout animals, developmental/programming studies, electrophysiology, histochemistry, neurochemistry, neuropharmacology, neuroanatomy, neuroimaging, endocrinology, autonomic physiology, immunology, chronic pain, ethological and other behavioural studies and clinical measures.
