Unique, common, and total contributions for predictors of spelling (MODEL 5): Orthographic decision, Single pseudo-word repetition, and Repetition of Pseudo-word Series tests. For each predictor, the overall standardized β coefficient, its t statistics, and the significance p value (according to regression analysis) are reported as well as the percentage of variance explained in the communality analysis (% R² = Total / R²).

MODEL 5: R² = 0.292; R² adjusted = 0.28; F_(3,128) = 17.19, p < .0001.
