Table 2.
Percentages of variance accounted for by length in characters (Nchar), length in syllables (Nsyl) frequency (Freq), and orthographic similarity (OLD20) in the Dutch Lexicon Project, the English Lexicon Project (monosyllabic and disyllabic words only; n = 22,143), and the French Lexicon Project (monosyllabic and disyllabic words; n = 19,184).

RT analyses calculated on the zRT scores and accuracy >0.66. Polynomials of the third degree were used to be able to simulate the sigmoid (cubic) frequency curve.
