Experimental social psychological study of group creativity

本研究旨在从社会心理学的角度探讨提高群体创造力的条件。首先，提出了创造力群体决策的过程模型。然后，在这个框架中，我阐明了本研究将创造性想法的“生成过程”作为群体创造力的基本过程。在回顾相关研究和发现之后，研究发现，群体过程本身对通过群体讨论产生创造性想法有抑制作用。在此基础上，笔者进行了一系列的实验研究，得出了一些重要的新发现。它们如下所示。首先，成员间沟通的不平衡僵化和成员间相似性的增加对群体创造力有抑制作用。第二，不同意见的相互作用引起的智力冲突激发了一种创造性想法的闪现，而不是消极的情感冲突作为敌意，进而增强了群体创造力。第三，元知识如报告结果的对象、其他成员的信息和知识的程度等对促进和抑制双方都有很强的影响。在结论中，我提出了一些关于群体创造力研究的观点。首先，我论证了群体工程方法和群体过程的社会心理学研究之间的系统联系的重要性。其次，笔者指出，群体创造力研究的更重要的任务是考察在不同成员的互动下，智力冲突而不是敌意占主导地位的因素。

In this study, I intended to investigate the conditions to enhance group creativity from social psychological viewpoint. First, I presented the process model of group decision making for creativity. Then, in this framing, I clarified that this study focused the "generation process" of creative ideas as the basic process of group creativity. After reviewing relational studies and findings, it was found that group processes themselves had inhibitory effects on generation of creative ideas through group discussion. And I argued that the effective and realistic way ti know the facilitative conditions for group creativity was making the inhibitory factors more clear, then developing the strategies to overcome.On the basis of arguments above, I conducted a series of experiments and got some important and new findings. They were as below. First, unbalanced stiffening of communication among members and increasing similarities of members had inhibitory influences on group creativity. Second, interaction of diverse opinions caused intellectual conflict stimulating a flash of a creative idea more than negative emotional conflict as hostility, then enhanced group creativity. Third, Metaknowledge such as, objects to report the fruit and the extent of other members' information and knowledge, had strong influences for both sides of enhancement and inhibition.In the conclusion, I argued some perspectives for croup creativity study. First, I demonstrated the importance of systematic linkage between group engineering approach and social psychological study of group processes. Second, I pointed out that the more significant task for group creativity study was to examine the factors making intellectual conflict dominant rather than hostility under interaction of diverse members.
