    Abstract

    Two experiments are presented that investigated the effects of horizontal saccadic eye movements and handedness on eyewitness memory for central and peripheral information. In both experiments, participants viewed a short video depicting a bank robbery and episodic memory was tested after a short delay. Experiment 1 used recognition memory and found an interaction between eye movement, handedness and type of information recalled. This indicated that eye movements enhanced memory to a greater extent for peripheral information for individuals classified as consistently handed. Experiment 2 used free-recall and found eye movement enhancement effects of similar magnitude for central and peripheral items. A similar pattern of eye movement effects was observed for both consistent and inconsistent-handed individuals. Inconsistent handers also had superior memory overall. The results are discussed in terms of theoretical accounts of eye movement effects and implications for the enhancement of eyewitness memory.
