The multidimensional-psychophysical scaling procedure was employed to construct verbal rating scales at the ratio scale level of measurement precision. The multidimensional individual differences scaling model (INDSCAL) demonstrated a one-dimensional solution in the group stimulus space, with the eight verbal descriptors and the eight electrical stimulus intensities interdigitated with respect to their perceived strength. A plot of these stimulus coordinates against a scale of electrical intensities in milliwatts yielded an exponential function. To construct the rating scales, the four attributes that could be discerned within the dimension-namely, perceived intensities of the electrical stimuli and the attributes of the subjective experiences evoked by the electrical stimuli: pain qualities, somatosensory qualities, and emotional qualities-were plotted as separate scales against a subjective intensity scale. Although not presented here, INDSCAL also yields a subject coordinate space that quantifies the importance or saliency to each subject of each pole, stoical or complainer, of the dimension.
采用多维心理物理标度程序，在测量精度的比率量表水平上构建言语评定量表。多维个体差异标度模型（INDSCAL）在组刺激空间中显示出一维解，八个言语描述符和八个电刺激强度在其感知强度方面相互交叉。将这些刺激坐标相对于以毫瓦为单位的电强度量表作图，得到一个指数函数。为了构建评定量表，在该维度内可辨别的四个属性——即电刺激的感知强度以及电刺激所引发的主观体验的属性：疼痛性质、躯体感觉性质和情绪性质——被作为单独的量表相对于主观强度量表作图。虽然此处未呈现，但INDSCAL还产生一个主体坐标空间，该空间量化了该维度中每个极点（坚忍者或抱怨者）对每个主体的重要性或显著性。
