Brain Pathology: Education
Introduction. In higher cortical functions we find written language characterized as a specific learning process of the human species. The process of writing can be acquired due to altered brain dysfunctions functional or organic nature diffuse and psychological disorders such as schizophrenia, dementia, anxiety attacks, etc.. Writing as neuropsychological process has been widely studied as an integral part of the different pictures emerging classifications aphasic aphasic and aphasic agraphia (pure agraphia). Then briefly describe the salient features of this disease acquired. Agraphia. Agraphia is defined as an acquired disorder of writing due to a focal brain injury.
She is frequently associated with organic brain damage in the angular gyrus. It is rare to find a pure form of agraphia and usually associated with other neurological disorders. Process models. One of the models used to explain the Clinching phenomenon is proposed by Heilman Roelgen and based on linguistic categories. These authors start from the premise that writing is based on two fundamental components: 1. Linguistic components: They are responsible for transforming the word heard (phonemes) in writing (graphemes) and consist of two systems: a) Lexical System: This system retains the visual image of the word known and can write what you do not hear phonologically such as irregular words (words with no correlation between sound and spelling, such as "stew" and homophones (words that sound the same but spelled differently in relation to the context, such as "heard" / "hole."). b) System Phonological: This system allows conversion of phoneme (sound unit) a grapheme (unit graphic or written). Example: we hear a word, decompose in their units (phonemes), we seek the grapheme that corresponds to and form the word.
This system allows us to write logotomas (words non-existent, meaningless) 2. Engine Components: This is the second process that sustains the write mechanism that allows the execution space of graphemes (writing). Classification of agraphia. Many writers such as Joe Stillman offer more in-depth analysis. Language agraphia. Are you interested in this item? Download here: Visit:
