Abstract: This paper introduces theoretical results of research oriented on development object-oriented models of filter systems of attention. The diagrammatical language UML is used as a means of modeling of attentional systems. Two filter-oriented hypothesis of focused attention offered by Broadbent and Treisman were chosen as prototypes. The paper includes: UML model of the structure of information in the sensory system, the classification of existing models of attention, and two UML models of the phenomenon of attention based on Broadbent's and Treisman’s hypothesis respectively. The study revealed that from the point of view of OO modeling, the model based on Broadbent’s hypothesis can be considered as a basic class, whereas the model based on Treisman’s hypothesis is its enhancement. Both UML models were used to explain results of some key experiments on dichotic listening tasks.

Keywords: Cognitive model, models of attention, object-oriented modeling, unified modeling language.
