The role of basic number processing in high mathematics achievement in primary school

While symbolic number processing is an important correlate for typical and low mathematics achievement, it remains to be determined whether children with high achievement also have excellent abilities. We investigated this question in 64 (aged 8 10), i.e., 32 persistent (above the 90th percentile) average-achieving peers (between 25th 75th percentile). Children completed measures of (comparison order). additionally roles spatial visualization working memory. High achievers were faster more accurate order compared average achievers, but no differences found magnitude comparison. demonstrated better ability, while group memory less clear. Spatial ability was only significant predictor membership. Our results therefore highlight role achievement.
