Over the last few years the study of brain plasticity gains increasing interest, focusing on how learning, thinking and acting changes the brains functional organization and structure. Handedness is of special interest in this respect since it brings up the question of structure and function of the human brain. This book presents two studies of this subject: 1. A comparison of a large sample of Right vs. Left- handed children, which showed similar cognitive capabilities and a high resemblance in the affective domain. (However, teachers evaluated Left-handers as having lower social skills.) 2. The examination of Right vs. Left-handed adults'' judgments of chimeric faces, which showed significant differences in their perceptual biases. The sum results may indicate significant differences in self organization between the two groups, and raises the need for further investigation of the different, procedural bottom-up aspects of learning related to handedness. This book may provide a better insight in the various aspects of Handedness, and as such would be of interest for parents and professionals in the fields of psychology, education and communication.
