| Abstract | Word frequency and orthographic familiarity were independently manipulated as readers’ eye movements
were recorded. Word frequency influenced fixation durations and the probability of word skipping
when orthographic familiarity was controlled. These results indicate that lexical processing of words can
influence saccade programming (as shown by fixation durations and which words are fixated). Orthographic
familiarity, but not word frequency, influenced the duration of prior fixations. These results
provide evidence for orthographic, but not lexical, parafoveal-on-foveal effects. Overall, the findings
have a crucial implication for models of eye movement control in reading: There must be sufficient time
for lexical factors to influence saccade programming before saccade metrics and timing are finalized. The
conclusions are critical for the fundamental architecture of models of eye movement control in reading—
namely, how to reconcile long saccade programming times and complex linguistic influences on saccades
during reading.
