【摘要】 本研究设计了2种抽象材料和4种具体材料的四卡问题，对436名大学生进行测试，以考察被试解决四卡问题时所采用的思维方式并检验命题内容对推理的影响。结果表明，四卡问题十分困难，具体内容的四卡问题并不能产生促进效应，大学生的推理表现出“匹配偏向”的特点。更多还原

【Abstract】 The selection task is a kind of conditional reasoning. In this research 6 selection tasks were designed,each two containing an abstract proposition and four concrete propositions. We tested 435 college students to investigate their ways of solving the selection tasks and verify the influence of the propositional contents upon reasoning. The result showed that the selection task was very difficult, and the selection task based upon concrete materials had no facilitation effect. The subjects’ reasoning exhibited the characteristics of a matching bias.更多还原
