Аннотация:In this study we discuss an important problem of interaction between local analyzers during the process of formation and functioning of concepts. The experimental work, aimed at studying the process of audiovisual integration, was based on artificial system of bimodal signs, included several conflict stimuli. Four types of subjects’ reaction to the conflict bimodal signs were found out. These types were described by mathematic model. Also we offer the neuron net model of audiovisual integration, based on obtained results and recent data.
