基于分组、子化和相加的可加子成分，推导了一个数学模型，用于解释三维块排列的量化延迟。Subitizing是人们用来直接量化少量对象而不计数的过程。结果发现，大多数人一致subitized多达四块。如果超过四个区块，人们会进行分组和添加，而模型能够解释这些数据。结构变量的紧凑性，对称性，线性，和平面性被证明有小的影响，相对于块的数量的大的影响量化lavelet。在这些结构变量中，紧凑性的影响最大，并在该模型中，这表明，视觉结构的知觉分组子组件的影响。
A mathematical model, based on additive subcomponents of grouping, subitizing and adding, was derived to account for quantification latencies of three-dimensional block arrangements. Subitizing is the process that people use to directly quantify a small number of objects without counting. It was found that most people consistently subitized up to four blocks. With more than four blocks, people resorted to grouping and adding, and the model was able to account for these data. The structural variables of compactness, symmetry, linearity, and planarity were shown to have small effects on quantification latencies relative to the large effect of number of blocks. Of these structural variables, compactness had the largest effect, and in terms of the model, it is suggested that visual structure had its effect on the perceptual grouping subcomponent.
