Background: The patients who have right cerebral hemispheric lesions have trouble in discourse implementation, but not in physical speaking, and furthermore, they suffer from concentration defects and ignorances of the left side. According to Tompkins these abnormal behaviors are caused by working memory load and cognitive process limitation. Because working memory is related to cognitive processing tasks and affects discourse comprehension and production. This study aims to find out the relationship between communicational deficiencies of the patients with right cerebral hemispheric lesions and their working memory declines.
Methods: The subjects are 14 males and 16 females respectively, in 40s to 70s, who suffer from right cerebral hemispheric lesions, and normal 10 males and 10 females each. The working memory tasks are digit span test and spatial span test.
Results: In the whole parts of working memory it was revealed that there were statistically meaningful differences of the capacity of the memory between the patients and the control. Besides, there were the significant differences of the capacity in gender only among the experimental group members.
Conclusion: The patients showed that they have some limitations in the ability both to save linguistic information temporally and to save and process spatio-temporal information, and also it can be inferred that working memory and the communicational deficiencies are closely connected to each other.
