A hierarchical biased-competition model of domain-dependent working memory maintenance and executive control

This chapter discusses a neurological implementation of a model that allows for concurrent activation of multiple representations that are distinct from activated areas of long-term memory, which may be domain-specific and involve activations associated with integrated objects arising from the binding of several different sensory features. Rather than referring to a focus of attention, their argument builds on the Desimone and Duncan biased-competition model in which the relative activation of these different representations influences activation elsewhere in the brain and consequently influences action.
