Abstract

Background : The main aim of this research was to assess the differences of visual memory in deaf and normal students according to plasticity of cortical brain.
Materials and Methods : This is an ex-post factor research. Benton visual test was performed by two different ways on 46 students of primary school. (22 deaf and 24 normal students). The t-student was used to analysis the data.
Results : The visual memory in deaf students was significantly higher than the similar normal students (not deaf).While the action of visual memory in deaf girls was risen in comparison to normal girls in both ways, the deaf boys presented the better action in just one way of the two performances of Benton visual memory test.
Conclusion : The action of plasticity of brain shows that the brain of an adult is dynamic and there are some changes in it. This brain plasticity has not limited to sensory somatic systems. Therefore according to plasticity of cortical brain theory, the deaf students due to the defect of hearing have increased the visual the visual inputs which developed the procedural visual memory.
