Word-to-text integration and antecedent accessibility: Eye-tracking evidence extends results of event-related potentials (ERPs).

Eye tracking and event-related potentials (ERPs) have complementary advantages in the study of reading processes. We used eye tracking to extend ERP evidence of Helder et al. (2020) that word-to-text integration at the beginnings and ends of sentences is primarily determined by local text factors (antecedents in a previous sentence) but that global factors (central theme) may make these antecedents more accessible in memory and thus facilitate their integration. The ERP evidence for these conclusions comes from the N400 on a target noun, which varied with the appearance of an antecedent in the previous sentence and whether that antecedent was related to the passage theme. Here, using the same materials, we report eye tracking evidence that reflects not only integration processes indexed by fixation on target words and words following, but also regressions to the antecedent, a measure not possible with ERPs. Interestingly, conclusions from eye-tracking measures align generally with those from Helder et al., but reading times did not consistently correspond to reduced N400s. A distinctive eye-tracking result is that when antecedents were not related to the central theme of the passage (thus less accessible in memory) there was a greater likelihood of return to the antecedent from the regions beyond the target word. These findings demonstrate an independent influence of both local and global context on reading patterns that are unique to eye-tracking measurement, thus both converging with ERP conclusions and adding new ones.
