AB Readers extract visual and linguistic information not only from fixated words but alsoupcoming parafoveal words to introduce new input efficiently into the language processingpipeline. The lexical frequency of upcoming words and similarity with subsequent fovealinformation both influence the amount of time people spend once they fixate the word foveally.However, it is unclear from eye movements alone the extent to which parafoveal wordprocessing, and the integration of that word with foveally obtained information, continues aftersaccade plans have been initiated. To investigate the underlying neural processes involved inword recognition after saccade planning, we coregistered EEG and eye movements during agaze-contingent display change paradigm. We orthogonally manipulated the frequency of theparafoveal and foveal words and measured fixation related potentials (FRPs) upon fovealfixation. Eye movements showed primarily an effect of preview frequency, suggesting thatsaccade planning is based on the familiarity of the parafoveal input. FRPs, on the other hand,demonstrated a disruption in downstream processing when parafoveal and foveal input differed,but only when the parafoveal word was high frequency. These findings demonstrate that lexicalprocessing continues after the eyes have moved away from a word and that eye movements andFRPs provide distinct but complementary accounts about oculomotor behavior and neuralprocessing that cannot be obtained from either method in isolation. Furthermore, these findingsput constraints on models of reading by suggesting that lexical processes that occur before an eyemovement program is initiated are qualitatively different from those that occur afterward.
