Using the standard parity judgment task, this study investigated the development of numerical-spatial representation. Participants were 314 healthy right-handed Chinese children (from kindergarteners to sixth graders) and adults. The results revealed that all age groups showed a significant (or marginally significant in the case of first graders) SNARC (spatial-numerical association of response codes) effect, indicating that Chinese children as young as kindergarteners already had developed automatic spatial representations of numbers (or the mental number line). Surprisingly, however, the size of the SNARC effect did not show much developmental change. These results are discussed in the context of the literature on spatial representations of numbers and on cross-cultural differences in early development of number cognition. (C) 2013 Elsevier Inc.
