摘要: Brain-electric correlates of reading have traditionally been studied with word-by-word presentation, a condition that eliminates important aspects the normal process and precludes direct comparisons between neural activity oculomotor behavior. In present study, we investigated effects word predictability on eye movements (EM) fixation- related brain potentials (FRPs) during natural sentence reading. Electroencephalogram (EEG) EM (via video-based tracking) were recorded simultaneously while subjects read heterogeneous German sentences, moving their eyes freely over text. FRPs time- locked to first-pass fixations analyzed according cloze probability currently fixated word. We replicated robust EMs N400 component in FRPs. The data then used model relation among fixation duration, gaze amplitude, trace time course EEG relative an extended Methodological Discussion section, review four technical data-analytical problems need be addressed when are free-viewing situations (such as reading, visual search, or scene perception) propose solutions. Results suggest recordings vision feasible useful consolidate findings from eye-tracking studies. Journal Experimental Psychology: General
