心智影像中功能联接对设计认知过程的影响

Effect of the Influence of Functional Connections in Mental Images on Design Cognition Process

根据语义网络理论,提出心智影像中的功能联接对设计时间、设计质量、设计结果的创新性影响关系的3个理论假设,采用原案分析法对14名机械专业研究生进行可调座椅概念设计认知实验,以验证该假设的正确性,并采用Mann-Whitney非参数检验法进行统计分析.结果表明,心智影像中知识单元之间的功能联接越多,则设计时间越短,设计质量越高,设计结果越具有创新性,即假设都成立.

According to the semantic network theory,three theoretical hypotheses were presented on the influence of functional connections in mental images on design time,design quality,and creativity of design results.A series of adjustable seat conceptual design cognition experiments with 14 postgraduates of mechanical major were conducted to test the hypotheses based on protocol analysis.The results of Mann-Whitney non-parametric tests show that the more the functional connections among knowledge units in mental images are,the less design time it takes,the higher quality design it produces,and the more creative design it conceives.So all the hypotheses hold.
