摘要
一、问题“认知的发展是发展心理学的一个最重要的方面,思维发展是其中的核心部分。”而推理又是重要的思维活动。“推理是判断和判断之间的联系,是在已有判断的基础上推出新的判断。”归纳和演绎是两种最基本的推理形式,“思维活动中,这两种推理形式不能孤立地存在,它们表现于不可分割的统一之中,是统一的思维过程的两个方面,两个环节。”
The purpose of this experiment isto study the development of 3-7-yr chil-dren's reasoning process under play-like condition,in which induction anddeduction are considered as two unsep-arable aspects of the reasoning process.One hundred and seventy-five subjectswere tested individually,and inquiriesand suggestions were given when neces-sary.The results show that there aredifferent forms and levels of children'sreasoning process;that 6 types of theirreasoning process reflect the gradullydeveloping tendency of reasoning;andthat inquiry and suggestion proceduremay facilitate the exploration of chil-dren's reasoning process.
