This experiment assessed a recent contention that cognitive pain-control strategies are effective because length of training produces demands irrespective of content of training. Participants held the dominant hand in ice water for 5 sec. They then estimated how long they expected to tolerate ice water using one of four cognitive pain-control strategies. People who used multiple cognitive strategies previously found to be effective experienced mean tolerance equal to that of subjects who used multiple cognitive strategies previously found to be ineffective. Participants then used the instructions while their hands were immersed in ice water. People tolerated the pain longer when using effective rather than ineffective strategies. The experiment demonstrated that the efficacy of cognitive pain-control strategies cannot be accounted for by length of instructions alone.
本实验评估了最近的一种观点，即认知性疼痛控制策略之所以有效，是因为训练时长会产生影响，而与训练内容无关。参与者将优势手放入冰水中5秒钟。然后，他们使用四种认知性疼痛控制策略之一来估计自己预计能忍受冰水的时长。先前发现使用多种有效认知策略的人与使用多种无效认知策略的人经历的平均耐受时间相同。随后，参与者在双手浸入冰水中时按照指令操作。使用有效策略时，人们忍受疼痛的时间更长。该实验表明，认知性疼痛控制策略的有效性不能仅由指令时长来解释。
