q3 i? Non-symbolic comparison COV became non-significant when any visuo-spatial predictor was added, and no number sense measure survived with more than two non-number sense predictors. → Szűcs Dénes 2014

Evidence¶

Szűcs Dénes 2014¶

Szűcs Dénes, Devine Amy, Soltesz Fruzsina, Nobes Alison, Gabriel Florence. (2014). Cognitive components of a mathematical processing network in 9-year-old children. Developmental Science. https://doi.org/10.1111/desc.12144

q3 · i? · associational · r2

Forced-entry regression models starting from number sense measures in the same 98-child sample; number sense predictors lost significance as visuo-spatial and reading variables were added, and "None of the number sense measures proved to be reliable when there were more than two non-number sense predictors in the model."

"Non-symbolic comparison COV invariably became non-significant when there was even a sole additional visuo-spatial predictor variable (visuo-spatial WM; Dot Matrix; Spatial Orientation) in the regression equation."

Discussion¶

Learner Variables¶

• Number Sense — predictor: learners who differ on it differ in outcomes
