摘　　要：个体学习符号分数的一个关键是能对其数值形成准确表征。现有研究假设符号分数表征的认知基础是人类自婴幼儿期就具有的非符号数量表征(如表征两个集合各自的数量,或两个数量的比例)。其证据包括表征非符号数量(尤其是非符号数量比例关系)和表征符号分数在行为和大脑神经活动层面上都表现出相关性。然而要说明非符号数量表征是符号分数表征的认知基础,还需更多研究表明两者在数量概念上的独特相关和因果联系,并阐明符号分数表征形成的认知机制。Representing the numerical value of symbolic fraction is central to the conceptual learning of symbolic fraction.The representation of symbolic fraction has been hypothesized to be built on non-symbolic magnitude representation(e.g.,representing the magnitude of a set,or the proportion between two magnitudes)that exists since human early infancy.The supportive evidence includes that non-symbolic magnitude representation,especially the non-symbolic representation for the proportion between quantities,is correlated with the representation for symbolic fraction in behavioral and brain neural responses.However,further research is needed to determine the unique and causal relation between non-symbolic magnitude representation and symbolic fraction representation,and to clarify the specific cognitive mechanism underlying symbolic fraction representation.
