The effect of experimentally induced anxiety on pain perception was examined using a signal detection discrimination experiment. The experimental condition consisted in unsignalled application of very painful stimuli which substantially raised state anxiety. The discrimination task included the total range of painful stimuli. The results indicated a range-specific effect of anxiety on pain, particularly on increased sensitivity in the upper range of intensities. The importance of testing the effect of anxiety over the whole range of intensities is stressed. That prior work considered only one intensity level may be the main reason why previous signal detection studies about pain and anxiety showed contradictory results.
采用信号检测辨别实验，研究了实验性诱导焦虑对疼痛感知的影响。实验条件包括无信号施加非常疼痛的刺激，这会显著提高状态焦虑。辨别任务涵盖了整个疼痛刺激范围。结果表明，焦虑对疼痛具有特定范围的影响，尤其是在强度较高的范围内会提高敏感性。强调了在整个强度范围内测试焦虑影响的重要性。先前的研究仅考虑一个强度水平，这可能是以往关于疼痛和焦虑的信号检测研究结果相互矛盾的主要原因。
