摘要:
数量可以分为物理量(非符号量)和符号量。物理量是一种在进化中形成的先验知识，人类在此基础上又创造出符号量来精确地表征数量关系。研究表明物理量与符号量的表征存在偏侧化现象：物理量的表征依赖于视空间系统对客体的加工，更多地表现出右半球优势；符号量表征则具有左半球优势，这可能是文化和大脑成熟共同作用的结果。文化复用理论强调文化对脑功能的塑造，可以用来解释数量表征偏侧化的演变，也暗示了数量认知的生存意义。
Number could be divided into two categories: the numerosity (or non-symbolic number) and the symbolic number. Numerosity is a kind of priori knowledge formed in evolution. Human further created the symbolic number based on numerosity to accurately describe relationships among numbers. The lateralization representations of both numerosity and symbolic number were demonstrated by considerable studies. The representation of numerosity was associated with object processing of visuospatial system of right hemisphere, while the left priority of symbolic number might be the result of interaction between culture and brain maturity. A cultural recycling hypothesis, which focused on the modulation of culture to human brain, may shed light on the evolution of the lateralization effect of numerical representation, and further implied the survival significance of numerical cognition.
