在20名受试者的面部和口腔中的12个位点上，对温暖和寒冷的感觉强度进行了心理测量。各地区对降温和升温的相对敏感性存在显著差异，尽管升温的敏感性范围大于降温。除了朱红的嘴唇和舌尖，口腔区域对温度的敏感性明显低于面部区域。冷却时未发现这种差异。例如，在硬腭上测试的最后位置表现出对冷却的阈上敏感性，其等于或超过面部上的大多数位置。舌尖和朱红唇对冷热都具有较高的敏感性，其中舌尖是迄今为止最敏感的口腔区域。
The intensity of sensations of warmth and cold was measured psychophysically at 12 loci on the face and in the mouth in 20 human subjects. Significant differences were found among areas in the relative sensitivity to both cooling and warming, although the range of sensitivities was greater for warming than for cooling. Except for the vermilion lip and the tongue tip, oral regions were significantly less sensitive to warming than were facial regions. No such difference was found for cooling. The most posterior location tested on the hard palate, for example, exhibited a suprathreshold sensitivity to cooling that equaled or surpassed that of most locations on the face. The tongue tip and vermilion lip possessed relatively high sensitivity to both warming and cooling, with the former locus emerging as the most thermally sensitive oral area so far tested.
