进行了两项实验，以确定注意力是否介导了情感分散因素对冷压疼痛的影响，或者启动和评估的认知过程是否最好地解释了这种影响。在实验一中，65 名男性受访者接触到从国际情感图片系统 (IAPS) 中选出的令人愉快、中性或不愉快的图片。同时进行冷加压试验。与基于启动和评估假设的预测一致，结果显示了不同条件下的线性趋势，例如随着画面愉悦度的变化，疼痛耐受性得分更高。第二项研究旨在检验疼痛线索在冷压疼痛的负面影响中的作用。三十九名男性受访者接触过令人不快的图片，这些图片要么包含或不包含与疼痛相关的内容。观看没有疼痛提示的图片的受访者比观看包含疼痛相关信息的图片的受访者耐受冷水的时间更长。讨论了可能导致观察到的差异的启动和评估过程，以及可能对增强疼痛耐受性有意义的情感干扰类型。 (C) 2001 年国际疼痛研究协会。由 Elsevier Science B.V. 出版。保留所有权利。
Two experiments were conducted to determine whether attention mediates the effects of affective distracters on cold presser pain, or whether the cognitive processes of priming and appraisal best account for the effects. In Experiment I, 65 male respondents were exposed to either pleasant, neutral or unpleasant pictures selected from the International Affective Pictures System (IAPS). The cold-pressor test was administered simultaneously. Consistent with predictions based on priming and appraisal hypotheses, results revealed a linear trend across conditions, such that pain tolerance scores were higher as a function of picture pleasantness. A second study was conducted to examine the role of pain cues in the effects of negative affect on cold presser pain. Thirty-nine male respondents were exposed to unpleasant pictures that either did or did not include pain-related material. Respondents who viewed pictures without pain cues tolerated the cold water for a longer period of time than respondents who viewed pictures that contained pain-related information. Priming and appraisal processes that might underlie the observed differences, and the type of affective distracters that could be meaningful for enhancing pain tolerance, are discussed.
