Summary of interactions of skill measures by lexical properties of words N and N−1 as predictors of eye-movement durations, obtained via mediation analysis (Appendix 3). All reported interactions are significant at the 0.05-level. Directions of coefficients for all reported interaction terms were identical within each type of interaction and are reported in parentheses.
