Comparison of clinical memory performance in blind veterans and matched sighted

Abstract

Background: Visual world experiences have an important role in the development of cognitive functions of brain. Exact and fast visual information is critical for brain cognitive functions. Pupose: The aim of this study is comparison of clinical memory function of blinds veteran with normal sighted matched person. Material and Methods: In this cross-sectional study, we compare 137 blinds and 124 sighted people in clinical memory performance. The test was Wechsler Adult Intelligence Scales-Revised (WAIS-R). Independent T Test was used to comparing blinds with sighted. Results: Age of blind group was 41.75±7.69 and in sighted group was 41.86 ±8.14. Findings show significant difference between two groups in sub scales and total scores of Wechsler. (P <0.000) Result shows no significant difference in retrieval subscale. (P=0.054) Discussion: Based on this study blinds have lower performance in memory functions. This finding can show correlation between clinical memory performance and visual information.
