ABSTRACT
The development of laterality and dominance is central to many of the Institutes' techniques. In 1900 Professor F. Lueddeckens proposed that right-handedness was the result of a higher blood pressure on the left side of the brain. An extension of the social harmony idea uses the powerful stigma that society has applied to left-handed persons. The gradual demise of Paul Broca's rule was brought about by accumulating evidence that, at least in some persons, speech and control of the preferred hand lay in different hemispheres. Some people with right-hemisphere speech have developed the faculty on that side as a first choice. Control of the body's movement, and the reception of sensory information, is fairly evenly divided between the two hemispheres such as left and right hemisphere. Lower animals display marked individual hemispheric differences, and 'dominance' for handedness can easily be demonstrated in rats, cats and chimpanzees. The power of human language lies precisely in the symbolic-conceptual domain.
