AbstractPeople map numbers onto space. The well-replicated SNARC effect indicates that people have a left-sided bias when responding to small numbers and a right-sided bias when responding to large numbers. This study examined whether such spatial codes were tagged to the ordinal or magnitude information of numbers among kindergarteners, and whether it was related to early numerical abilities. Based on the traditional magnitude judgment task, we developed two variant tasks – namely the month judgment task and the dot judgment task – to elicit ordinal and magnitude processing of numbers respectively. Results showed that kindergarteners oriented small numbers towards the left side and large numbers towards the right side when processing the ordinal information of numbers in the month judgment task, but not when processing the magnitude information in the number judgment task and dot judgment task – suggesting that the left-to-right spatial bias was probably tagged to the ordinal but not magnitude property of numbers. Moreover, the strength of SNARC effect was not related to early numerical abilities. These findings have important implications for the early spatial representation of numbers and its role in numerical performance among kindergarteners.
