采用连续台座法和门控台座法测量振动触觉幅差阈。在这两种情况下，相对DL作为刺激强度的函数而降低，并且在大多数情况下，结果可以被描述为接近韦伯定律。发现通过连续基座法测量的DL作为在12至1000 ms的范围内的刺激持续时间的增加的函数大幅减少。相比之下，通过门控基座法测量的DL仅受刺激持续时间的变化的轻微影响。得出的结论是，时间总和的过程可以体现在减少的DL在连续基座的大小，但不是门控基座，范式。(C)1996年美国声学学会。
Vibrotactile amplitude difference limens (DLs) were measured by the continuous pedestal and gated pedestal methods. In both cases, the relative DL decreased as a function of the intensity of the stimulus and the results, in most cases, could be described as a near miss to Weber's law. DLs measured by the continuous pedestal method were found to decrease substantially as a function of increases in stimulus duration over a range of 12 to 1000 ms. In contrast, DLs measured by the gated pedestal method were only slightly affected by changes in stimulus duration. It was concluded that the process of temporal summation can manifest itself in reducing the size of the DL in the continuous pedestal, but not the gated pedestal, paradigm.
