设计认知研究旨在探讨人类设计师的认知机制和思维过程。在之前的研究中，我们比较了有经验和没有经验的设计师的认知活动，以确定导致设计创造力的设计策略。然而，所采用的设计策略是否有效，设计过程是否得到有效改进，仍然是未知的。认知效率描述了设计师在概念设计过程中如何优化心理资源以实现创造力，并通过设计师的心理努力和设计结果的创造力水平直接衡量。结果表明，经验丰富的设计师比经验不足的设计师产生的设计概念更多，质量更高，种类也更多。认知效率测试表明，设计专业知识有助于提高质量的认知效率得分。此外，研究发现一些设计师采用的系统化设计方法与高认知效率有关。可见，认知效率评价在设计师培训、设计方法论评价、设计过程改进等方面具有实际应用价值。
Design cognition research aims to investigate the cognitive mechanisms and thought processes of human designers. In previous research, the cognitive activity of experienced and inexperienced designers has been compared in order to identify design strategies leading to design creativity. However, it is still unknown whether the design strategies applied are effective and whether the design processes are efficiently improved. In this paper, cognitive efficiency, describing how designers optimize mental resources to achieve creativity in conceptual design processes, was directly measured by the mental effort of designers and the creativity level of design outcomes. The results showed that the experienced designers generated more design concepts with higher quality and variety than did the inexperienced designers. The cognitive efficiency measures indicated that design expertise contributed to improving cognitive efficiency scores of quality. In addition, the systematic design method used by some designers was found to be related to high cognitive efficiency. It can be seen that the evaluation of cognitive efficiency has practical applications for designer training, design methodology evaluation, and design process improvement.
