(The inter-correlation of these measures is presented in Supplementary Table 2 .) A stepwise regression using these predictors of individual passage comprehensibility indicated that only Syntactic Simplicity (which predicted better comprehension) approached significance in explaining the variance in passage comprehensibility ( R 2 = 0.24, F (1,14) = 4.45, MSE = 0.0001, p = 0.053386).
