Abstract

A phenomenon of a mismatch of the bimodal ERP and the sum of unimodal ERPs was used in our research. The aim was to determine how efficiency of bimodal integration correlates with amplitude of mismatch in groups of observers preferring giving priority to visual or auditory information. It was discovered that the revealed dependences are of opposite character in the compared groups. It is concluded that amplitude of mismatch correlates with efficiency of integration, and efficiency of integration is higher, the priority of visual input is more expressed that the auditory one.
