This study investigates the differences in eye movement patterns when foreign learners of Korean read newspapers in Korean versus their native language. Using eye-tracking technology, we examine how reading proficiency influences gaze behavior, fixation duration, and overall reading time. The study hypothesizes that high-proficiency learners will exhibit similar eye movement patterns across both languages, while low-proficiency learners will show longer fixations and slower reading speeds when reading in Korean. To test this, low-proficiency participants engaged in a repeated reading intervention using Korean newspapers over a training period. Post-intervention results revealed that consistent exposure to Korean texts reduced differences in reading behavior, aligning more closely with patterns observed in native-language reading. These findings suggest that extensive reading in the target language can significantly enhance reading fluency and comprehension, particularly for lower-level learners.
