Table 5.
Contributions to R2 for variables when added first to the model (first-in), and unique R2 contribution (last-in). PTAN = number of phonological neighbors; PGTAN = number of phonographic neighbors; p(P|G) = reading consistency, p(G|P) = spelling consistency. Total model R2 (marginal, i.e., fixed effects only) = 57.05%. p values based on Chi-squared test (log likelihood), *** p < 0.001, ** p < 0.01, * p < 0.05, ~ p < 0.10
