[The model of attention dynamics in perception].
A new model of perception of an elementary external stimulus is proposed on the basis of attention dynamics of a subject of perception. A local quantitative measure of attention is introduced with regard to connection of attention with analyzer excitability. The solution of the model is compared to the dynamics of distribution of the visual analyzer excitability in the process of perception measured experimentally. A formula of time dependence of attention on the evoked potential amplitude is presented. The theoretical amplitude dynamics is compared to the experimental results. The example of reconstruction of evoked potential on the basis of the model is given. Pieron's law is deduced in the framework of the model. The theoretical relationship between the reaction and stimulus intensity corresponds to the Stivens's law.
