【摘要】 为了探讨在选择任务中表象表征存在的可能性以及抽象材料选择任务困难的原因,该研究设定了材料的内容、规则以及证明规则的要求均完全相同,只是在呈现方式上形象性不同的两种抽象选择任务;然后把两种不同的选择任务分别对数量大致相当的大学生进行了测试。结果发现,不采用类似卡片这种形象性很强的材料呈现方式显著的提高了人们在抽象选择任务中的正确率。实验结果支持了选择任务中表象表征的存在及其为选择任务困难原因之一的观点。更多还原

【Abstract】 In order to find out in knowledge-lean selection task whether people using mental image representation or not,two experiments are explored.The material used in one experiment is not like the card that used in classical selection task and supposed to activate strong image.The material in the other experiment is material used in the classical selection task.Excluding the difference above,the material in the two experiments are the same.The results show that significant difference is found between the two experiments.So the ideal which people using mental image representation and such representation lead people behaving irrationally is supported by the result.更多还原
