Professor Luria’s book thus marks a further and decisive step toward the eventual coalescence of neurology and psychology, a goal to which only a few laboratories on the East and West have been devoted over the last decades. The book is unique in its organization. The first half deals with observations and interpretations concerning the major syndromes of man’s left cerebral hemisphere:
Those grievous distortions of higher functions traditionally described as aphasia, agnosia, and apraxia. There is also a detailed and brilliant analysis of the syndrome of massive frontal-lobe involvement. The entire second half of the book is given over to a painstaking description of Professor Luria’s tests, many of them introduced by himself, and set out in such detail that anyone could repeat them and thus verify Professor Luria’s interpretations. The two halves of the book are equally challenging and original. In the first, more theoretical, section, Professor Luria gives an account of the major syndromes in terms that reject with the same force the traditional localizationist view -the notion of discrete centers for different aspects of language, of calculation or writing- and the opposite view of holistic function of the cerebral hemisphere, a view clearly incompatible with clinical and experimental fact. In a similar way, Professor Luria’s re-analysis of agnosia and apraxia reveals inadequacies of these clinical shorthand expressions, he points out that more elementary sensory and motor changes shade into the allegedly isolated aspects of distorted “higher” function, whether of recognition or skilled movement. As a result of this balanced approach, a further traditional distinction falls by the wayside—the traditional opposition in the description of aphasia between the
