Approximate Number Sense (ANS) is an intrinsic intuition and innate cognitive function. It helps children to roughly determine if a quantity is larger or smaller than another. In the current study, we examined relative roles of ANS and intelligence on early arithmetic development in children aged 4-6. Our purpose was 1) to examine whether children aged 4-6 can solve non-symbolic multiplication problems and 2) to examine effects of ANS on early arithmetic development after controlling out effects of intellectual ability. Twenty one young children (4-6 years old) performed non-symbolic multiplication tasks (i..e, multiplication 2 and 4) and a ANS task. Results showed that children as young as 4 years old can solve both non-symbolic multiplication problems above chance level. Also, we found that the efficiency of ANS measured by ANS RTs played a critical role for non-symbolic multiplication 2 task performance even after controlling out effects of IQ. Overall, we conclude that preschoolers as young as 4 years old who don't have prior learning experience of multiplication problems can solve non-symbolic multiplication problems, which might be explained by children's ANS functions.
