The measurement of differential thresholds (DLs) for lifted weights normally involves lengthy test sessions. This is due partly to the statistical techniques for measuring the threshold and partly to the methods adopted to present the stimuli. Attempts to speed up test procedures tend to produce unreliable DL estimates, or to measure the sense of force or effort rather than weight perception. To facilitate the measurement of DLs for lifted weights, an Apple microcomputer was programmed to generate Wetherill tracking procedures and was interfaced with two stimulus bearing turntables. Various lifting methods are easily implemented, and DLs are reliably and quickly measured. The adaptation of the apparatus for general use in investigating the haptic sense modality is discussed.
测量举起重量的差别阈限（DLs）通常需要较长的测试时间。这部分是由于测量阈限的统计技术，部分是由于呈现刺激所采用的方法。试图加快测试程序往往会产生不可靠的差别阈限估计值，或者测量的是力或努力的感觉而非重量感知。为便于测量举起重量的差别阈限，对一台苹果微型计算机进行编程，使其生成韦瑟里尔跟踪程序，并与两个承载刺激的转盘相连接。各种举起方法都能轻松实现，而且能可靠、快速地测量差别阈限。还讨论了该仪器在触觉感觉模态研究中的通用适应性。
