实验室计算机允许检测和辨别阈值被快速、有效和准确地测量。本文综述了心理测量函数和阈值的一般性质，并对各种感觉阈值的估计方法进行了总结。最有效的方法，在原则上，使用最大似然阈值估计，详细检查。四种技术进行了讨论，最大限度地减少报告的问题，发现与最大似然法。一个包的FORTRAN子程序，ML-TEST，它实现了最大似然法，描述。这些子程序可根据作者的要求提供。
Laboratory computers permit detection and discrimination thresholds to be measured rapidly, efficiently, and accurately. In this paper, the general natures of psychometric functions and of thresholds are reviewed, and various methods for estimating sensory thresholds are summarized. The most efficient method, in principle, using maxium-likelihood threshold estimations, is examined in detail. Four techniques are discussed that minimize the reported problems found with the maximum-likelihood method. A package of FORTRAN subroutines, ML-TEST, which implements the maximum-likelihood method, is described. These subroutines are available on request from the author.
