From a cognitive perspective, the major challenge lies in the coordination and management of the various channels of information…

A detailed description of a layered network model is provided, with computer simulations of key associative learning phenomena and predictions generated from the model. The model is compared to more conventional theories of learning to learn and configural learning. (SLD)
