Eye Tracking and Its Application to Reading Studies


Presented by


Dr. Marcus Johnson

Ph.D., University of North Carolina, USA

Eye tracking involves the monitoring of the moment-to-moment gaze position of an individual while the person performs a task of interest. Though eye tracking devices are used in a wide range of paradigms (e.g., visual world search, smooth pursuit, attention monitoring), perhaps the most useful application of eye tracking technology is in the field of psycholinguistics. The ability to know where an individual is looking when reading text can provide great insight into the manner in which linguistic materials are processed. In recent years, psycholinguistic researchers have developed a set of measures that can be used to obtain insight into the relative difficulty that pieces of text pose to readers. These measures have been designed to distinguish the various cognitive processes that are involved in reading. These processes include first-pass difficulty, disambiguation, and late resolution. We will discuss eye tracking in general, eye tracking as it is commonly used in psycholinguistics, and the measures that are commonly used to distinguish cognitive processes that are involved in reading. Though this discussion of how eye tracking experiments typically proceed will be made in the context of EyeLink eye tracking systems, the methods and measures discussed will may be generalized to other eye tracking systems as well.





Dr. Marcus Johnson received his MS and Ph.D. in Psychology (Cognitive) from the University of North Carolina at Chapel Hill, USA in 2006 and 2008, respectively. He applies eye-tracking techniques to the psycholinguistic study of sentence comprehension in English and Chinese. He has developed a set of data analysis tools for eye tracking research that can be widely applied to social science research beyond language domains. He is currently working as a Research Support Specialist for SR Research, Ltd. During his service at SR Research Ltd. he has continuously developed advanced data analysis tools for eye-tracking research, worked on integrating definitions of reading measures, provided training for psycholinguistic labs worldwide and helped the setups of labs in the integrative interface between eye-tracking and brain scanning (MRI, MEG, EEG) paradigms.
