The document describes a study that investigated the development of the Spatial-Numerical Association of Response Codes (SNARC) effect in children ages 5 to 9. The study adapted a magnitude judgment task used in a previous study. All 4 child participants, ranging in age from 5 years 10 months to 9 years 4 months, displayed the SNARC effect by responding faster to small numbers with their left hand and larger numbers with their right hand. While age did not significantly impact the strength of the effect, the study was limited by its small sample size.
