信号检测理论（SDT）可以应用于心理学的任何领域，其中必须区分两种不同类型的刺激。我们描述了其中的几个领域，以及通过应用SDT可以实现的优势，然后讨论了用于研究可判别性的三个最流行的任务，以及SDT规定的量化这些任务中的绩效的措施。给出了测量的数学公式，以及使用查找表、专门为SDT应用程序开发的计算机软件和通用计算机软件（包括电子表格和统计分析软件）计算测量的方法。
Signal detection theory (SDT) may be applied to any area of psychology in which two different types of stimuli must be discriminated. We describe several of these areas and the advantages that can be realized through the application of SDT Three of the most popular tasks used to study discriminability are then discussed, together with the measures that SDT prescribes for quantifying performance in these tasks. Mathematical formulae for the measures are presented, as are methods for calculating the measures with lookup tables, computer software specifically developed for SDT applications, and general purpose computer software (including spreadsheets and statistical analysis software).
