It is a learned skill that engages a complex set of cognitive procedures. By virtue of its complexity, it is vulnerable to disruption with many different kinds of brain damage, especially aphasia. This study investigated the reading disabilities in Chinese aphasic patients by giving them a series of reading related tasks, including discrimination between visually similar words, matching between different scripts of single words, homophone matching task, single word naming task, single word and sentence comprehension tasks. The results showed that almost all aphasic patients had some degree of reading disabilities. In general, although anterior or Broca’s aphasic patients often had difficulty in naming single words (alexia), they often preserved the ability to understand single words or even simple sentences. While posterior or Wernicke’s aphasic patients had more variable ability in terms of their ability in single word comprehension. In the aspect of analysis of the cognitive processes in the reading disability, it was found that all aphasic patients in this study could distinguish between different characters with similar orthography, which suggested that they retained normal ability in orthographic visual analysis. Furthermore, most aphasic patients, especially those of anterior lesions, could match the simplified script form of a single character with its visually dissimilar, complex script form. In contrast, none could perform the homophone matching task. These findings might be able to support the hypothesis that direct grapheme-phonetic conversion is not an important route in Chinese character or word reading. |
