在这里，我们报告了两个实验，研究了自己的皮肤（自我触摸）与其他人的皮肤（人际触摸）的触觉感知。在第一个实验中，13名女性参与者按照沿着四个感知属性对自己手掌和前臂掌侧的皮肤进行评级，然后对其他几名参与者进行评级。使用视觉模拟量表对感知的光滑度、柔软度、粘性和愉悦度进行评级。一个人自己的皮肤被评为不如别人的皮肤舒适。对于内部和人际接触，前臂皮肤被评为比手掌皮肤更光滑，更柔软，更少粘性和更舒适。在第二个实验中，10对女性参与者对彼此的手掌和手掌前臂皮肤进行评级，在使用皮肤润肤剂之前和之后评估被触摸者的皮肤，以改变皮肤感觉。与第一个实验一样，其他人未经处理的皮肤被评为比参与者自己的皮肤更令人愉快，前臂与手掌的差异被复制。然而，润肤剂对自我评估的影响通常大于其他人的评估，并且部位效应显示手掌与掌侧前臂的积极感觉和愉悦感增加更大。这两个实验的不同结果表明，受刺激的生态重要性影响的注意力，对评估触摸皮肤比皮肤的所有权或被动触摸皮肤中的额外受体对自我触摸的贡献更重要。在这两个实验中，触摸皮肤的愉悦感与皮肤的感知光滑度和柔软度相关，与其感知粘性的负面关联趋势较弱，与使用无生命表面的先前研究一致（例如，纺织品和砂纸）。(C)2008 Elsevier B.V.保留所有权利。
Here we report two experiments that investigated the tactile perception of one's own skin (intrapersonal touch) versus the skin of other individuals (interpersonal touch). In the first experiment, thirteen female participants rated, along four perceptual attributes, the skin of their own palm and volar forearm, then that of several of the other participants. Ratings were made using visual analogue scales for perceived smoothness, softness, stickiness, and pleasantness. One's own skin was rated less pleasant than the skin of others. For both intra- and interpersonal touch, the forearm skin was rated smoother, softer, less sticky and more pleasant than the palmar skin. In the second experiment, ten pairs of female participants rated each other's palm and volar forearm skin, with the skin of the touched individual being assessed before and after the application of skin emollients that alter skin feel. As in the first experiment, the untreated skin of others was rated more pleasant than the participants' own skin, and the forearm versus palm differences were replicated. However, the emollient had generally larger effects on self-assessments than the assessments of others, and the site effect showed greater positive sensory and pleasantness increases for palm versus volar forearm. The disparate results of the two experiments suggest that attention, influenced by the ecological importance of the stimulus, is more important to assessment of touched skin than ownership of the skin or the contribution to self-touch made by the additional receptors in the passively touched skin. In both experiments, the pleasantness of touched skin was associated with the skin's perceived smoothness and softness, with weak trends toward negative associations with its perceived stickiness, consistent with prior research using inanimate surfaces (e.g., textiles and sandpapers).
