Figure 4.

Grand average plot for the upper and lower tertiles of frequency (logarithmic class). Note that already at word onset, the effects have begun to diverge; the effects at a given word in a naturalistic context reflect the sum of the context and word-local, complex interactions. Large variances in word length enhance this effect. Nonetheless, the overall effect of frequency is so large that the change overcomes the initial offsets. This is visible as the change in sign for the regression coefficients in Figure 3.
