Pain interrupts, distracts and takes effort to ignore. Focusing our research attention upon this central aspect of pain experience, an experimental paradigm is introduced to study the disruptive nature of pain. Healthy volunteers were exposed several times to an electrical pain stimulus and a control stimulus. Tone probes were presented immediately (100 ms) and later on (1500 ms) after pain/control onset, and after pain/control offset (1000 ms). Results clearly showed disruption during pain. This disruptive effect was most marked immediately after onset. No differential results between pain and control conditions were observed later on during the pain experience. These results are interpreted within current cognitive and psychophysiological theories of attention. Emphasis is placed upon the importance of the experimental investigation of the role of attention in pain processing.
疼痛会打断、分散注意力，且需要努力去忽视。将我们的研究注意力集中在疼痛体验的这一核心方面，引入了一种实验范式来研究疼痛的干扰性质。健康志愿者多次暴露于电疼痛刺激和对照刺激下。在疼痛/对照开始后立即（100毫秒）、稍后（1500毫秒）以及疼痛/对照结束后（1000毫秒）呈现音调探测信号。结果清楚地表明在疼痛期间存在干扰。这种干扰效应在开始后立即最为明显。在疼痛体验的后期，未观察到疼痛和对照条件之间的差异结果。这些结果在当前关于注意力的认知和心理生理学理论中得到了解释。重点强调了对注意力在疼痛处理中的作用进行实验研究的重要性。
