Abstract： 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.
