Although there is anecdotal evidence for the psychoanalgesic properties of distraction, research evidence is equivocal. Drawing on the clinical and experimental studies of attention-based coping strategies for pain control, and the theoretically driven 'cognitive' models of the human attention system, two experiments are reported. Experiment One demonstrates that chronic pain patients suffering high intensity pain show significantly impaired performance on an attentionally demanding task when compared to low pain patients and normal controls. Experiment Two tests the hypothesis that the low intensity pain patients in Experiment One are coping with the dual demand of processing the pain and processing the task by switching quickly between these attentional demands. The results of both experiments are discussed in terms of the evidence for the analgesic properties attention based coping strategies with clinical pain populations and re-addresses the literature on coping with pain in terms of cognitive theories of attention.
尽管有传闻证据表明分散注意力具有心理镇痛特性，但研究证据并不明确。基于对用于疼痛控制的基于注意力的应对策略的临床和实验研究，以及人类注意力系统的理论驱动“认知”模型，报告了两项实验。实验一表明，与低疼痛患者和正常对照组相比，遭受高强度疼痛的慢性疼痛患者在一项需要注意力的任务上表现出明显受损。实验二检验了这样一个假设，即实验一中的低强度疼痛患者通过在这些注意力需求之间快速切换来应对处理疼痛和处理任务的双重需求。根据针对临床疼痛人群的基于注意力的应对策略的镇痛特性证据，对两项实验的结果进行了讨论，并根据注意力的认知理论重新审视了关于应对疼痛的文献。
