This is because information acquirement of a human being is made by visual system like imager, signs and symbols as audio system like human language, natural language and music. Acquired information is stored in our memory device, and if other information is entered, new information structure is made through recombination of memory. The combination of visual elements like imager and audio information like spoken language influences our memory device and works more clearly on the recombination of information. What is important here is that stimulation status and level for visual or audio system is related to the efficient delivery of information.
