最近的研究表明，害怕疼痛的人往往会报告更多负面的疼痛经历。注意力机制似乎在感知疼痛刺激时可能特别重要，特别是在害怕疼痛的人中。目前的研究基于一种用于检查情绪障碍中有偏见的认知过程的范式，调查了对疼痛的恐惧是否与更大的选择性注意偏差有关，后者倾向于与疼痛相关的刺激。为了确定这种偏见的性质，刺激材料根据它们是与疼痛感觉有关、与社会威胁情况有关还是相对积极而不同。与那些对疼痛恐惧程度较低的人相比，那些对疼痛恐惧程度较高的人表现出对疼痛相关信息的选择性注意偏向。无论是社会威胁还是积极刺激，都没有发现群体差异。这些结果表明，为什么那些对疼痛有高度恐惧的人特别容易受到负面疼痛体验的影响，一个原因可能是由于注意力过程的偏见。讨论了旨在减少这种偏见的认知干预的建议，以及未来研究的方向。(C)2001年国际疼痛研究协会。爱思唯尔科学公司出版。版权所有。
Recent research indicates that people who are fearful of pain tend to report more negative pain experiences. It also seems that attentional mechanisms may be particularly important in the perception of painful stimuli, especially amongst pain fearful individuals. Drawing on a paradigm used to examine biased cognitive processes in the emotional disorders, the current study investigated whether the fear of pain would be related to a greater selective attentional bias in favour of pain-related stimuli. In order to determine the nature of this bias, stimuli material were varied in terms of whether they were related to pain sensations, were related to socially threatening situations or were relatively positive. Those with a high fear of pain exhibited a selective attentional bias towards pain-related information, compared to those classified as low in the fear of pain. No group differences were found for either social threat or positive stimuli. These results indicate that one reason why those with a high fear of pain are particularly susceptible to negative pain experiences could be due to biased attentional processes. Suggestions for cognitive interventions designed to reduce such biases are discussed, as are directions for future research. (C) 2001 International Association for the Study of Pain.
