Abstract

Experiment 1 found that mixed-handedness, which is associated with increased interaction between the left and right cerebral hemispheres relative to strong right-handedness, was associated with an earlier offset of childhood amnesia. In Experiment 2, bilateral saccadic eye movements, which have been shown to enhance interhemispheric interaction, were also associated with an earlier offset of childhood amnesia. These results build upon a growing body of research indicating an interhemispheric basis for the retrieval of episodic memories. Moreover, the results of Experiment 2 suggest that interhemispheric interaction has its effect on the retrieval, not encoding, of episodic memories.
