我们擅长用触觉辨别物体的柔软度和温度等特性。以前的研究已经调查了每个对象属性的本质，但这些属性之间的相互作用并没有完全理解。触觉柔软度的感知依赖于多种感官线索，如接触区域的大小、压痕深度和施加的力。除了这些线索外，刺激的温度可能通过改变对刺激顺应性变化的敏感性来促进触觉柔软感知。为了验证这一假设，我们进行了两个心理物理实验，在实验中，受试者在接触可变形物体后估计感知到的柔软程度。我们改变了刺激的顺应性和温度。在低温条件下（9-15°C）的顺应性线性函数比室温条件下（21-25°C）的顺应性线性函数更陡峭。这些结果表明，温度可以通过增加对顺应性差异的敏感性来增强我们对可变形表面的触觉柔软感。
We are adept at discriminating object properties such as softness and temperature using touch. Previous studies have investigated the nature of each object property, but the interactions between these properties are not fully understood. Tactile softness perception relies on multiple sensory cues such as the size of the contact area, indentation depth, and force exerted. In addition to these cues, the temperature of the stimulus may contribute to tactile softness perception by changing the sensitivity to changes in stimulus compliance. To test this hypothesis, we conducted two psychophysical experiments in which the subjects estimated the magnitude of perceived softness after touching deformable objects. We varied the compliance and temperature of the stimuli. The linear functions of compliance fit to the magnitude estimates under cold conditions (9–15°C) were steeper than the functions fit to the magnitude estimates under room temperature (21–25°C). These results indicate that temperature can sharpen our tactile softness perception of deformable surfaces by increasing the sensitivity to differences in compliance.
