Implicit Learning of Spatial Configuration Occurs without Eye Movement

Abstract

AbstractStudies have demonstrated that eye movements enhance visual memory. However, the role of eye movement in implicit learning is not clear. We investigated whether implicit learning of spatial configuration requires eye movement using the contextual cueing paradigm. Eye movements were restricted by instructing participants to maintain fixation on the center of a display during a visual search. The results demonstrated that contextual cueing occurs even without eye movements. Furthermore, contextual cueing effects were obtained more rapidly when eye movements were restricted compared to when eye movements were allowed. The findings suggest that eye movements mediate the learning progress in contextual cueing: stabilization of spatial layout representation by restriction of eye movements induces a rapid learning of configuration.
