摘要: 本文有两个目的。第一,介绍决策论中的平均概率分数的协方差分解方法——一种评估判断能力的新方法。第二,探索协方差方法与信号检测论的关系。按照信号检测论评价法程序进行的两个实验证明:1.协方差分解方法能够把人的判断能力及其主观态度区分开。2.协方差分解方法在处理感觉事件上(重量感觉)与信号检测论同等有效。

Abstract: The purposes of this paper are twofold. First, to introducea covariance decomposition of the mean probability score in decisiontheory (abbreviated as CDMPS). Secondly, to explore the relationbetween the CDMPS and TSD. Two experiments have been madeaccording to the confidence rating method of TSD. The results of theexperiments proved: (a) The CDMPS can discriminate a person's abilityof judgement from his or her attitude when a decision is made. (b)TheCDMPS has the same effect as the TSD in dealing with sensory eventssuch as the sensation of weight.
