Rate of information processing during simultaneous presentation of auditory and visual information

If the display time of TV pictures, etc. is not sufficient, it is impossible to understand the displayed information. This paper investigated the relationship between the given amount of simultaneously presented visual and auditory information and the display time required to process that information in order to determine optimal display time in TV pictures, etc. The relationship was defined as a function of the co-relevance of the visual and auditory information presented. As a result, the co-relevance of the two types of information did not affect the relationship. The increment of display time required to process both types of information during simultaneous presentation was nearly constant for each amount of information. Therefore, the rate of information processing did not differ between single- and simultaneous-presentation conditions
