The spatial-numerical association of response codes(SNARC)effect is an effect in which digital information associates with spatial properties when human brain processes digital information,and has been one of the hot research topics in cognitive psychology since its discovery.However,the spatial mechanism of the SNARC effect is still controversial.This paper presented a review of the Egocentric Reference and Allocentric Reference Frames of the SNARC effect,and further analyzed the organization system of its spatial reference in terms of two hypotheses:the hierarchical system and the internal and external system of the spatial reference of the SNARC effect.And it proposed that future research could explore the spatial reference mechanism of the SNARC effect in the vertical direction and its spatial reference organization system,and further examine the characteristics and relationships between the spatial reference behaviors and neural mechanisms of the SNARC effect in both horizontal and vertical directions.
