Pain is an experience that powerfully influences the way we interact with our environment. What is less clear is the influence that pain has on the way we perceive our environment. We investigated the effect that the anticipation of experimental pain (THREAT) and its relief (RELIEF) has on the visual perception of space. Eighteen (11F) healthy volunteers estimated the distance to alternating THREAT and RELIEF stimuli that were placed within reachable space. The results determined that the estimated distance to the THREAT stimulus was significantly underestimated in comparison to the RELIEF stimulus. We conclude that pain-evoking stimuli are perceived as closer to the body than otherwise identical pain-relieving stimuli, an important consideration when applied to our decisions and behaviors in relation to the experience of pain.
疼痛是一种能有力地影响我们与环境互动方式的体验。而疼痛对我们感知环境方式的影响则不太明确。我们研究了实验性疼痛预期（威胁）及其缓解（缓解）对空间视觉感知的影响。18名（11名女性）健康志愿者估计了放置在可及空间内交替出现的威胁和缓解刺激的距离。结果表明，与缓解刺激相比，对威胁刺激的估计距离被显著低估。我们得出结论，引发疼痛的刺激比其他相同的缓解疼痛的刺激被感知为更靠近身体，这在应用于我们与疼痛体验相关的决策和行为时是一个重要的考虑因素。
