It is commonly believed that the human sense of warmth is inferior in spatiotemporal acuity to the tactile senses. However, little or no evidence is available about the active feeling of warmth. We investigated the ability of people to detect in an active way small changes of warmth on very small areas (2-mm x 2-mm resistors). To that end, a new procedure was developed to measure perception of warmth. The results indicate that people who are able to detect the warmth stimuli perceive small incremental changes and that detection performance improves as stimulus intensity increases. Male subjects seem to be less sensitive than female subjects at lower level of stimulation, but this relationship is reversed at higher levels of stimulation.
人们普遍认为，人类对温暖的感知在时空敏锐度方面不如触觉。然而，关于温暖的主动感受的证据很少或几乎没有。我们研究了人们以主动方式检测非常小的区域（2毫米×2毫米的电阻器）上的微小温暖变化的能力。为此，开发了一种新的程序来测量对温暖的感知。结果表明，能够检测到温暖刺激的人能够感知到微小的增量变化，并且检测性能随着刺激强度的增加而提高。在较低刺激水平下，男性受试者似乎比女性受试者不太敏感，但在较高刺激水平下，这种关系会逆转。
