Results showed a significant difference in the age of episodic memory recall, the mixed-handed group on intermediate recalling incidences from an earlier age tha n that of right-handers. While there is some! attention for Christman, however, Dr. Zaidel considers does not have much confidence in the findings, pointing to a lack of physical evidence to support the idea of mix-handedness resulting in better inter-hemispheric communication. I agree with Christmans theory that mixed-handedness gives great inter-hemispheric...If you want to get a full essay, order it on our website: OrderEssay.net
