Eye tracking in bilingual neurolinguistics
summary
Eye-tracking with an Eyelink Portable Duo records silent and aloud reading from a corpus of Russian and polysynthetic Adyghe sentences for 50 adult bilinguals (ages 18–60). Results show more fixations and longer reading time in Adyghe, first fixations bias toward word-beginnings, and weaker word-frequency effects than Russian; language switching produces longer gaze durations. Claims: parallel activation of both languages, mixed shared/separate neural representations (proposed fMRI integration), and plans to add voice data and scanpath analysis.
