摘要

先前的研究表明，由于设计问题固有的模糊性和复杂性，设计任务可能对认知要求很高。然而，很少有研究考察工程设计过程中认知负荷的演变以及认知负荷子维度与设计任务结果之间的联系。为了解决这一差距，目前的工作调查了两个不同的设计任务:创意和原型的认知负荷的演变，以及认知负荷和设计任务结果之间的关系。结果表明，设计师在构思和原型设计过程中所经历的认知负荷存在显著差异。此外，研究结果表明，构思过程中的认知负荷与想法的独特性、有用性和优雅性呈正相关。

The Cognitive Costs of Design Tasks: Examining Cognitive Load Through Verbal and Physical Indicators

Prior work has demonstrated that design tasks can be cognitively demanding, due to the inherent ambiguity and complexity of design problems. Few studies, however, have examined the evolution of cognitive load during the engineering design process and the linkages between sub-dimensions of cognitive load and design task outcomes. To address this gap, the current work investigates the evolution of cognitive load across two distinct design tasks: ideation and prototyping, and the relationship between cognitive load and design task outcomes. Results suggest that there is a significant difference in cognitive load experienced by the designer during ideation and prototyping. Additionally, findings suggest that cognitive load during ideation is positively correlated with the uniqueness, usefulness, and elegance of ideas.

期刊介绍： The Journal of Mechanical Design (JMD) serves the broad design community as the venue for scholarly, archival research in all aspects of the design activity with emphasis on design synthesis. JMD has traditionally served the ASME Design Engineering Division and its technical committees, but it welcomes contributions from all areas of design with emphasis on synthesis. JMD communicates original contributions, primarily in the form of research articles of considerable depth, but also technical briefs, design innovation papers, book reviews, and editorials.
