作为一个初步的步骤，在感官辨别的信心模型的介绍，作者提出了两个不同的来源的不确定性命名的心理学史上，L。L. Thurstone和Egon Brunswik。作者回顾的数据表明，有经验以及概念之间的差异的2种模式的不确定性，因此，单独的模型的信心，需要在任务中占主导地位的Thurstonian和Brunswikian不确定性。本文提出了一类由Thurstonian不确定性支配的任务的计算模型：具有配对比较的感觉辨别。感官采样模型预测决策，信心评估，以及简单的心理物理辨别任务中反应时间的复杂模式（J. V. Baranski和W。M. Petrusic，1991）。该模型还解释了在成对比较的感觉辨别中经常观察到的不自信倾向（M。J. Juslin，Bjorkman & A. Winman，1993; C. S. Peirce & J. Jastrow，1884）.
As a preliminary step towards the presentation of a model of confidence in sensory discrimination, the authors propose a distinction between 2 different origins of uncertainty named after 2 of the great probabilists in the history of psychology, L. L. Thurstone and Egon Brunswik. The authors review data that suggest that there are empirical as well as conceptual differences between the 2 modes of uncertainty and thus that separate models of confidence are needed in tasks dominated by Thurstonian and Brunswikian uncertainty. The article presents a computational model for 1 class of tasks dominated by Thurstonian uncertainty: sensory discrimination with pair comparisons. The sensory sampling model predicts decisions, confidence assessments, and the complex pattern of response times in simple psychophysical discrimination tasks (J. V. Baranski and W. M. Petrusic, 1991). The model also accounts for the disposition towards underconfidence often observed in sensory discrimination with pair comparisons (M. Bjorkman, P. Juslin, & A. Winman, 1993; C. S. Peirce & J. Jastrow, 1884).
