进行了3个数字决策实验，以探讨概率分类决策中保守性截断位置的原因。118名受试者（主要是大学生）分别看到代表男性和女性身高的5位数，他们对每一个观察结果的反应取决于他们对该数字代表男性身高的确定程度。在每个实验中，收益矩阵和先验概率水平都是正交变化的。先验概率对截止点位置的影响大于收益矩阵，即使收益矩阵所规定的偏差大于先验矩阵所规定的偏差。结果表明，概率匹配的规则，根据Ss选择一个截止点。(14参考）（PsycINFO数据库记录（c）2016阿帕，保留所有权利）
Conducted 3 numerical-decision experiments to examine the cause of conservation cutoff placement in probabilistic categorization decisions. 118 Ss, predominantly university students, were shown 5-digit numbers representing the heights of men and women, and they responded to each observation depending on how certain they were that it represented the height of a man. Payoff matrices and prior probability levels were varied orthogonally and within Ss in each experiment. Prior probabilities had larger effects on cutoff location than payoff matrices, even when the bias prescribed by the payoffs was greater than that prescribed by the priors. Results suggest a probability-matching rule according to which Ss chose a cutoff point.(14 ref)(PsycINFO Database Record (c) 2016 APA, all rights reserved)
