Abstract

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).

摘要

信号检测理论（SDT）可应用于心理学的任何领域，在这些领域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辨别性的三个最常用的任务，以及SDT规定的用于量化这些任务中表现的测量方法。给出了测量方法的数学公式，以及使用查找表、专门为SDT应用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）来计算这些测量值的方法。
