Table 2.

Mean fixation probability, first-fixation duration, gaze duration, and single-fixation duration on wordn, single-fixation duration on wordn close to wordn+1, and mean first-fixation and gaze duration on wordn+1 as a function of the frequency of wordn and the parafoveal preview of wordn+1

Note: FP = mean fixation probability, in percentages; FFD = first-fixation duration, in ms; GD = gaze duration, in ms; SFD = single-fixation duration, in ms; SFDC = single-fixation duration, three character positions or fewer, in ms. Standard deviations are shown in parentheses.
