没有一种全面的语言可以描述触摸的体验。三个实验进行了建立一个触摸词汇的步骤。在实验I中，49名参与者对262个形容词描述触觉的感官、情感和评价方面进行了评价。在实验二中，参与者对最具描述性的词语进行了成对的差异性评价。多维缩放（MDS）解决方案表示单词下面的语义感知空间，导致触摸感知任务（TPT）由26个“感觉”属性（例如，颠簸）和14个“情感”属性（例如，愉快的）。在实验III中，40名参与者使用TPT率看不见的纹理材料，主动移动或被动接收对食指垫，掌前臂，和两个腋下网站。MDS在实验II和III中证实了类似的语义感知结构。因子分析实验III数据分解的感官属性评级为标记粗糙度，滑，桩和坚定性的因素，和情感属性评级为舒适和唤醒因素。不同材料和地点的因素得分不同。当参与者被动地而不是主动地接受刺激时，报告了更大强度的感官和情感反应。TPT在识别身体部位和与触摸相关的感知差异模式方面的敏感性证实了这种新型语言/感知工具的有效性和实用性。
No comprehensive language exists that describes the experience of touch. Three experiments were conducted to take steps toward establishing a touch lexicon. In Experiment I, 49 participants rated how well 262 adjectives described sensory, emotional and evaluative aspects of touch. In Experiment II, participants rated pairwise dissimilarities of the most descriptive words of the set. Multidimensional scaling (MDS) solutions representing semantic-perceptual spaces underlying the words resulted in a touch perception task (TPT) consisting of 26 'sensory' attributes (e.g., bumpiness) and 14 'emotional' attributes (e.g., pleasurable). In Experiment III, 40 participants used the TPT to rate unseen textured materials that were moved actively or received passively against the index fingerpad, volar forearm, and two underarm sites. MDS confirmed similar semantic-perceptual structures in Experiments II and III. Factor analysis of Experiment III data decomposed the sensory attribute ratings into factors labeled Roughness, Slip, Pile and Firmness, and the emotional attribute ratings into Comfort and Arousal factors. Factor scores varied among materials and sites. Greater intensity of sensory and emotional responses were reported when participants passively, as opposed to actively, received stimuli. The sensitivity of the TPT in identifying body site and mode of touch-related perceptual differences affirms the validity and utility of this novel linguistic/perceptual tool.
