In precis form, a profile of those with minimal, stress minimal, brain dysfunction who have, hearteningly, grown up not only to adjust but to achieve. (Is the elimination of the stigma ""retarded"" by the euphemism ""exceptional"" a necessary adjunct to the new enlightenment?) In any case Siegel itemizes with fine specificity the particular problems -- learning, perceptual, behavioral -- with their subdivisions (motivational defidiency, negativism, social immaturity, impulsivity, poor self-concept, etc.) until greater maturity is reached although defensive mechanisms are usually retained. The discussion proceeds in stages -- through adolescence, junior high and high school, college and on to employment, marriage, the army. The second half of the book outlines goals (as yet partial -- we do not have all the answers) via the attitudes to be inculcated or the services and facilities to be instituted. A professional audience seems likeliest.
