疼痛会打断注意力。这种中断对注意力控制的参与程度和与感觉相关的威胁程度高度敏感。然而，很少有研究将这些因素结合在一起。本研究旨在探讨在低威胁和高威胁条件下疼痛对高阶注意任务的干扰效应。50名参与者完成了一项n-背部任务，一项注意力转换任务和一项注意力分散任务，一次是疼痛，一次是无痛。25名参与者被给予标准的任务指令（控制条件），其余的被给予额外的口头信息，旨在增加威胁（威胁条件）。疼痛打断了参与者的表现在两个n-back和注意力转换任务，但不是在分散注意力的任务。此外，威胁操纵似乎并没有显着改变疼痛对这些注意力任务的影响。然而，独立的疼痛，威胁没有中等性能的注意力分散任务。这些研究结果支持的鲁棒性的影响，疼痛对性能的高阶注意力任务。未来的研究需要检查哪些因素改变疼痛引起的认知中断。(C)2012年国际疼痛研究协会。由Elsevier B出版。V.保留所有权利。
Pain is known to interrupt attention. This interruption is highly sensitive to the extent of involvement of both attentional control and the level of threat associated with the sensation. However, few studies have examined these factors together. This study aimed to examine the interruptive effect of pain on higher-order attentional tasks under conditions of low and high threat. Fifty participants completed an n-back task, an attentional switching task, and a divided attention task, once in pain and once without pain. Twenty-five participants were given standard task instructions (control condition), and the remainder were given additional verbal information designed to increase threat (threat condition). Pain interrupted participant performance on both the n-back and attentional switching task, but not on the divided attention task. The addition of the threat manipulation did not seem to significantly alter the effect of pain on these attentional tasks. However, independent of pain, threat did moderate performance on the divided attention task. These findings support the robustness of the effect of pain on performance on higher-order attention tasks. Future research is needed to examine what factors alter the cognitive interruption caused by pain. (C) 2012 International Association for the Study of Pain. Published by Elsevier B. V.
