Predicting Native Language from Gaze
Table 1: Number of participants and mean MET English score by native language group.
['[EMPTY]', '[BOLD] # Participants', '[BOLD] English Score']
We recruited 182 adult participants. Of those, 37 are native English speakers and 145 are ESL learners from four native language backgrounds: Chinese, Japanese, Portuguese and Spanish. All the participants in the experiment are native speakers of only one language. The ESL speakers were tested for English proficiency using the grammar and listening sections of the Michigan English test (MET), which consist of 50 multiple choice questions. The English proficiency score was calculated as the number of correctly answered questions on these modules. The majority of the participants scored in the intermediate-advanced proficiency range. Additionally, we collected metadata on gender, age, level of education, duration of English studies and usage, time spent in English speaking countries and proficiency in any additional language spoken.
