摘要

威胁性刺激会产生不同的影响,包括工作记忆任务中反应时间(RT)的增加。这可能反映了工作记忆的中断,或者是一种可逆的冻结状态。在当前的一系列实验中,我们使用了虚拟攻击情绪斯滕伯格任务(cVAEST)来研究预期威胁导致的可逆减速。在这项任务中,视觉中性线索会指示在斯特恩伯格任务的维持期间,未来的虚拟攻击是否可能发生。三项研究(人数分别为 47、40 和 40)由健康的成年参与者在线完成。主要假设是 cVAEST 会唤起预期性减速。此外,这些研究还旨在探索这项新任务的细节,特别是提示刺激和探测刺激之间的间隔以及记忆集的大小。所有研究都发现,威胁预期会减慢工作记忆任务的反应时间。此外,研究 1(记忆集大小为 3)显示,当攻击发生在所有提示刺激间隔(CSI)时,RT 会下降。在研究 2 中,使用了一个项目的最小记忆集,在这种情况下,攻击发生后的反应时间仅在线索呈现后不久(CSI 200 和 500 ms)较快,此时威胁和安全线索的反应时间都较高。研究 3 以更精细的时间间隔重复了研究 2 的结果。研究结果证实,在独立的工作记忆任务中,对攻击刺激的预期会可逆地减慢反应速度。cVAEST 可以为研究这种由威胁引起的反应迟钝提供有用的方法。

Anticipated Attack Slows Responses in a Cued Virtual Attack Emotional Sternberg Task.

Threatening stimuli have varying effects, including reaction time (RT) increase in working memory tasks. This could reflect disruption of working memory or, alternatively, a reversible state of freezing. In the current series of experiments, reversible slowing due to anticipated threat was studied using the cued Virtual Attack Emotional Sternberg Task (cVAEST). In this task visually neutral cues indicate whether a future virtual attack could or could not occur during the maintenance period of a Sternberg task. Three studies (N = 47, 40, and 40, respectively) were performed by healthy adult participants online. The primary hypothesis was that the cVAEST would evoke anticipatory slowing. Further, the studies aimed to explore details of this novel task, in particular the interval between the cue and probe stimuli and the memory set size. In all studies it was found that threat anticipation slowed RTs on the working memory task. Further, Study 1 (memory set size 3) showed a decrease in RT when the attack occurred over all Cue Stimulus Intervals (CSIs). In Study 2 a minimal memory set of one item was used, under which circumstances RTs following attacks were only faster shortly after cue presentation (CSI 200 and 500 ms), when RTs were high for both threat and safe cues. Study 3 replicated results of Study 2 with more fine-grained time intervals. The results confirm that anticipation of attack stimuli can reversibly slow responses on an independent working memory task. The cVAEST may provide a useful method to study such threat-induced response slowing.
