Abstract: Eye-tracking technology is an objective and scientific indicator of cognitive effort during language processing.Applying eye-tracking technology can help analyze sight translation (ST) process from a psycholinguistic perspective.This article gives a brief introduction of ST-related studies by means of eye-tracking in recent years which mainly focus on cognitive effort, reading pattern, source language interference, errors and translation strategies.These studies have attempted to establish a link between interpreters' eye movement parameters and interpreting process.In light of these studies, the author summarizes existing problems from different perspectives.The author believes that integration of eye-tracking and other data collection methodologies and study of ST process in a multimedia environment will deepen and enrich the study of ST process.
