Abstract

The effects of handedness and saccadic bilateral eye movements on autobiographical recollection were investigated. Recall of autobiographical memories was cued by the use of neutral and emotional words. Autobiographical recollection was assessed by the autobiographical memory questionnaire. Experiment 1 found that mixed-handed (vs. right handed) individuals demonstrated greater levels of autobiographical recollection on the components of seeing, hearing, and emotion. Experiment 2 found that following 30 s of bilateral eye movements, greater levels of autobiographical recollection were demonstrated on the components of reliving, seeing, hearing, emotion, self-perspective and veridicality. The results extend previous research by showing that the recollective components of real world memories can be enhanced by either mixed-handedness or eye movements. In addition, these results provide a bridge between laboratory studies of recollection and autobiographical recollection. The findings are considered in terms of research on the cognitive neuroscience of autobiographical memory.
