Eye-Movement Reinstatement

Studying eye-movement patterns as a window into memory recall

Overview

Eye movements during recall often retrace the spatial layout of the original experience—a phenomenon called eye-movement reinstatement. We study how these gaze patterns relate to the quality of memory retrieval and how they interact with neural reactivation measured by fMRI.

Key Questions

  • Do the eyes “replay” the spatial structure of a remembered scene?
  • Does fixation reinstatement support memory in older adults?
  • How do eye-movement reinstatement and neural reactivation co-occur during mental imagery?
