目的 通过定量的实验研究，分析设计的直觉性，解答“什么样的图形更能吸引人的注意”的问题。方法 采用心理学经典的点探测范式进行实验设计，测量视觉符号的“开眼”认知度。结果 虽然得出的数据曲线随图形的形状变化略有不同，但总体来看图形缺失1/3时反应时间最短。结论 基本图形缺失1/3时，图形认知度最高、识别最迅速，不同图形间的差异较小，判断较稳定，吸引人注意的同时又不会对完全形态产生困惑，能够对视觉符号设计产生积极影响。

The work aims to conduct quantitative research to analyze the intuitiveness of design to answer the question that "what kind of graphics are more attractive". The classical point detection paradigm of psychology was adopted to conduct experimental design to measure the "eye-opening" perception of visual symbols. The data results obtained were slightly different between different graphs. But in general, the response time was the shortest when 1/3 of the graphics was missing. That is, when 1/3 of the basic graphics is missing, the graphics recognition is the highest and the recognition is the fastest. The difference between different figures is small, and the judgment is stable. It attracts attention without confusion about the complete form and can have a positive impact on visual symbol design.
