Parker, Buckley, and Dagnall (2009) showed participants a series of pictures accompanied by a narrative. They followed this up by asking them a number of misleading questions about the specifics of the story. Participants were then directed to move their eyes either laterally, vertically, or not at all. The authors found that lateral eye movements led to better memory for the contents of the pictures and narrative. In addition, participants who moved their eyes from side to side were less apt to adopt the misinformation elements into their recollections.
