虽然过度警觉可能在一些临床疼痛综合征中发挥作用，但对疼痛刺激的实验性警觉很少被研究。我们使用连续执行任务（CPT）评估对疼痛的警惕性，在该任务中，受试者对中等强度的疼痛目标刺激做出反应，这些刺激发生在一系列轻度疼痛的非目标中。我们评估了未检测到的目标（失误），反应时间（RT）和心理激活（紧张唤醒）。在其他感觉模态的CPT任务期间，失误和RT（警惕性降低）增加。我们假设我们的CPT会影响与疼痛、焦虑和注意力资源限制相关的警觉性表现。结果表明，随着时间的推移，警惕性下降的失误增加，虽然RT不变。虽然走神并不影响警觉性的表现，内在的注意力疼痛驱动命中RT和失误的数量。这导致以疼痛为重点的受试者在CPT疼痛任务上表现更差，RT更慢，每个块的失误更多。在持续性疼痛治疗期间，刺激显着性的变化与疼痛强度的变化相关，而疼痛不愉快与紧张的觉醒相关。CPT性能在实验警惕疼痛和心理激活与特质焦虑，如测量的Spielberger状态-特质焦虑量表和神经质，如测量的NEO五因素清单。特质焦虑和神经质可能发挥重要作用，在一个人的倾向，纠缠于疼痛和解释疼痛为threatening.NEW & NOTEWORTHYSubjects检测到中度疼痛的目标刺激，在一列轻度疼痛的非目标刺激，这导致了警觉性的性能指标，包括错过的目标，反应时间，和心理激活。这些表现指标与对疼痛和特质焦虑的内在关注有关。高特质焦虑和神经质分数的受试者，倾向于参加疼痛，有更大的紧张性觉醒和较差的警惕性表现，这可能是重要的心理方面的警惕疼痛。
Although hypervigilance may play a role in some clinical pain syndromes, experimental vigilance toward painful stimuli has been studied infrequently. We evaluated vigilance toward pain by using a continuous performance task (CPT), in which subjects responded to moderately intense painful target stimuli, occurring in a train of mildly painful nontargets. We assessed nondetected targets (misses), reaction times (RTs), and psychological activation (tense arousal). During time on task in CPTs of other sensory modalities, there is an increase in misses and RTs (vigilance decrement). We hypothesized that our CPT would influence vigilance performance related to pain, anxiety, and limitation of attentional resources. The results showed a decrement in vigilance over time as misses increased, although RTs were unchanged. While mind-wandering did not influence vigilance performance, intrinsic attention to pain drove both hit RTs and number of misses. This resulted in pain-focused subjects performing worse on the CPT pain task with slower RTs and more misses per block. During the CPT, the change in stimulus salience was related to the change in pain intensity, while pain unpleasantness correlated with tense arousal. CPT performance during experimental vigilance to pain and psychological activation were related to trait anxiety, as measured by the Spielberger State-Trait Anxiety Inventory and neuroticism, as measured by the NEO five factor inventory. Trait anxiety and neuroticism may play important roles in an individual’s predisposition to dwell on pain and interpret pain as threatening.NEW & NOTEWORTHYSubjects detected moderately painful target stimuli in a train of mildly painful nontarget stimuli, which resulted in vigilance performance metrics including missed targets, reaction times, and psychological activation. These performance metrics were related to intrinsic attention to pain and trait anxiety. Subjects with high trait anxiety and neuroticism scores, with a predisposition to attend to pain, had greater tense arousal and poorer vigilance performance, which may be important psychological aspects of vigilance to pain.
