Sequential Bilingualism Studies: A Foreign Language from a Psycholinguistic Perspective

In line with the broad understanding of bilingualism in modern psycholinguistics, the use of a foreign language is also considered an object of study within this research theme. The aim of this line of research is to describe language processing in a foreign language, identify its differences from processing in the native language, and explore possibilities for improvement in foreign language learning and teaching.

Using the MECO L2 dataset, which contains eye-movement data from reading texts in English as a foreign language by participants with 12 different native languages, machine learning models were tested to predict both English proficiency level and the participant’s native language. The results demonstrated the possibility of predicting a participant’s native language (ROC-AUC = 0.997) and foreign language proficiency (R²-score = 0.899) based on eye-movement data during reading in a foreign language combined with demographic information.
