Психологический анализ строения письма: история изучения аграфий в зарубежной нейропсихологии (часть 1)
The analytical review of development of approaches to the structure of writing and the nature of agraphia in foreign neuropsychology is presented. In the first part of the paper the early theories (Wernicke-Lichtheim’s, Leischner’s, Pitres’, Chedru-Geschwind’s, Laine and Martilla’s, Barrière and Lorch’s theories) are discussed. The analysis is performed based on Russian neuropsychology statements where a set of two parameters characterizing the system structure of the psychic function is used. The first parameter corresponds to the internal structure of writing (the function of writing is treated as an undivided whole or a whole consisting of several components). The second parameter corresponds to the interfunctional relations between writing and other functions (describes if writing is a separate independent function or consists of components common to other psychic functions). In Russian neuropsychology foreign theories are traditionally considered as theories of narrow localizationalism. It is established however that in most reviewed theories writing is considered as a function with complex multicomponent structure containing components common to other psychic functions that provide the interaction between different functions.
