Abstract

Attention is a complex system subserved by at least three interacting attentional networks in the brain. This paper describes a computational model of attentional networks, developed in the framework of leabra. We evaluated the model using attentional networks test and the simulation results fitted the behavioral data well. The model provides a computational explanation of how the three attentional networks work together to achieve the function of attention.
