Table 2.
Mean, standard deviation and ranges of coefficient values from the LMEM's for the nine variables of interest per variant. Underlined variables correspond to the variables subsequently selected in Step 2 and reported in Table 4. For lexicality, positive coefficients indicate better performance for words, as opposed to pseudowords. For the continuous variables (i.e., length, position, imageability, frequency, PG probability, Orthographic N., Phonological N.) positive coefficients indicate better performance for higher values on those variables. For position-quadratic, positive coefficients indicate better performance on the two ends of a word compared to the middle positions.
