Document Summary
Reading and writing closely realted to listening and talking. Reading and writing skills for person w/aphasia resembled speaking and comprehending abilities. Ex: patients with broca"s aphasia understand what they read about as well as they understand speech but their reading aloud is poor. Patients w/conduction aphasia have difficulty reading when read aloud, often make semantic paraphasias (saying synonyms for words) just like they do when repeating what they hear. Some patients with transcortical sensory aphasia may read aloud accurately but fail to comprehend what they read. Pure alexia: loss of ability to read without loss of ability to write; produced by brain damage: a. k. a pure word blindness or alexia without agraphia. Dejerine had patient w/pure alexia lesion in visual cortex of left occipital lobe and posterior end of corpus callosum: patient could write but lost ability to read, if shown his own writing, could not read. Can recognize words spelled aloud to them. Didn"t lose memories of spelling of words.
