拟物化设计曾经在界面设计的发展中扮演者引领潮流的角色，而扁平化设计是近年来崭露头角的设计风格。基于认知心理学、用户体验研究和感性工学的理论基础，本研究从情感及认知体验两个维度探究了两种设计风格之间的一致与差异。本研究共进行了两个实验。在实验一用户情感体验研究中采用了语义差异法进行研究，结果说明，两中设计风格的用户界面在整体情感体验上没有显著差异，但各自具有不同特点，给予用户不同的感受。研究二采用了视觉搜索范式来探究两种用户界面的认知体验差异，并探讨了认知负荷和使用年限的影响。对反应时进行了MANOVA分析发现，认知负荷（F(1,40)=84.55, p< 0.001）、用户界面设计类型（F(1,40)=4.51，p<0.05）和使用年限（F(1,40)=84.55, p<0.001）三个变量的主效应均显著，而交互作用均不存在显著差异。可见，扁平化设计在情感和体验上都具有一定的优势。

The skeuomorphism design has played a leading role in the development of the interface design, and the flat design has become the predominating design style of apps and websites in recent years. Based on the cognitive psychology, user experience research and Kansei Engineering theory, this study explores the consistence and differences between the two design strategies from the emotional and cognitive experience. Two experiments were carried out in this study. The experimental results in the first semantic difference study indicated that there is no significant difference between design styles in overall emotional experience level, but each has different characteristics, giving users a different feeling. Study two using a visual search paradigm to explore two kinds of user interface of the cognitive experience found in different levels of cognitive load. The results show that flat design user interface response time was significantly shorter than skeuomorph design user interface. In addition, the year of using smart phones or computers is also an important indicator of the search task.
