Infant''''s Number Representations:Object-file and Analog Model
婴儿数量表征的客体档案和类比模型

Number representation and its development in human mind is one of the important topics in psychology. A series of theoretical and methodological advances have been made since 1970s. In this paper, studies investigating numerical competence in human infants are introduced briefly and two classes of models which have generally dominated current theories of numerical representation in human infants are discussed. Substantial experimental evidence suggests that infants possess an inherent mental mechanism for number. And this mechanism serves as a foundation for developing mathematical thought.
