The goal of this project was to examine how various factors such as word frequency, structural complexity, and predictability affect the eye movements of non-native speakers of English during reading. Unfortunately, COVID-19 related restrictions have prevented the collection of eye movement data (the setup of the experimental equipment requires the participants and experimenter to be in a small enclosed space). As an alternative, we investigated theoretically related issues looking at how structural complexity and predictability influence the reading times of native speakers of English, by replicating findings from Staub, Foppolo, Donati, and Cacchetto (2018) using an on-line reading task as well as by collecting sentence completion data from native speakers of English. These results will be used to construct a new experiment testing an alternative explanation for the results in Staub et al. (2018). This will allow us to better understand the factors affecting language comprehension of native speakers, and serve as an additional baseline for the research described in the original version of this proposal.
