本研究的目的是测量箔厚度的触觉辨别能力，并提出这种辨别过程的感觉信息处理机制。在实验 1 中，使用不锈钢箔测量厚度的差异阈值。对于 8、10、20、30、40 和 50 μm 的箔厚度，差异阈值分别为 5.9、6.1、6.4、7.5、9.0 和 10 μm。在实验2中，比较了不锈钢箔和铜箔的主观厚度。从实验结果可以得出结论，受试者利用材料变形信息来区分箔厚度。人类具有区分薄材料厚度的能力。 John、Goodwin 和 Darian-Smith (1989) 测量了薄金属板（标准板的厚度为 0.2 毫米）的触觉辨别能力，发现可以辨别大约 0.075 毫米的厚度差异。他们提出了受试者使用的策略的几种假设，以及受试者感知手指关节角度所需的所有策略，精度约为 0.1°。然而，人类可以区分比他们研究中使用的板更薄的材料。本研究的目的是测量非常薄材料的厚度辨别能力，并提出这种辨别的信息处理机制的假设。
The purpose of this study was to measure tactile discrimination ability of foil thickness and propose sensory information processing mechanisms for such discrimination processes. In Experiment 1, difference thresholds for the thickness were measured using stainless foils. The difference thresholds were 5.9, 6.1, 6.4, 7.5, 9.0, and 10 μm for a foil thickness of 8, 10, 20, 30, 40, and 50 μm, respectively. In Experiment 2, subjective thickness between stainless and copper foils was compared. From the results of the experiments, it is concluded that the subjects discriminate foil thickness using material distortion information. Humans possess the ability to discriminate between the thickness of thin materials. John, Goodwin, and Darian-Smith (1989) measured tactile discrimination ability of thin metal plates (thickness of standard plates were 0.2 mm) and found that a difference in thickness of approximately 0.075 mm could be discriminated. They presented several hypotheses of strategies used by the subjects, and all strategies required for the subjects to sense the angles of finger joints to a precision of about 0.1 °. However humans can discriminate between thinner materials than the plates used in their study. The purpose of this study was to measure thickness discrimination ability for very thin materials and propose a hypothesis of information processing mechanisms for such discrimination.
