摘要: 支持理论是一个关于主观概率判断的非外延性理论,它有以下几个主要观点:1.主观概率判断受到描述的影响,具有描述的依赖性;2.主观概率判断的结果是判断者对中心假设的相对支持的反映;3.主观概率在二元判断中表现出二元互补性,在多元判断中表现出次可加性;4.主观概率判断存在分解效应和促进效应

关键词: 支持理论, 二元互补性, 次可加性, 分解效应, 促进效应

Abstract: Support theory is a nonextensional theory of subjective probability judgment, which has several arguments: (1) subjective probability is influenced by description, which has description-dependence. (2) subjective probability reflects the relative support for the focal hypotheses. (3) subjective probabilities are complementary in binary case and subadditivity in general case.4 subjective probability judgment has unpacking effect and enhance effect

Key words: support theory, binary complementarity, subadditivity, unpacking effect, enhancement effect
