The human brain has two spheres--a left side and a right side. There is growing evidence that the language one first learns as a child determines which side of the brain is dominant for the rest of the person's life. People who are right-brain dominated think and behave differently from those who are left-brain oriented. In this insightful and provocative book, Boye Lafayette De Mente, internationally known for his books on the influence of langage on the cultures of China, Japan, Korea and Mexico, presents the Japanese as being the most right-brained people on the planet, and proposes that it is the right-brain left-brain factor that explains why the Japanese make such high-quality products. He also argues that predominately left-brained people (Americans and others) must learn how and when to use the right sides of their brains if they are to achieve their full potential--and offers guidelines for becoming dual-brained.
