| summary | Many present-day theories of working memory adhere to the view that the central executive is the core of the working memory system. As such it is thought to be responsible for controlled processing, task coordination, and many other important functions. In contrast to this theoretical richness, the empirical foundations of the concept are rather poor. Baddeley has argued in favour of fractionation of the central executive as a research strategy. In a similar vein, decomposition of the central executive in terms of a number of simpler processes has been advocated. In the present talk, it will be argued that executive or cognitive control is common to all these "executive" processes and that this control is an emergent property of the architecture of human cognition. A tentative model will be presented that allows for such an emergent control and next some results of a research program aiming at decomposition of the central executive will be discussed. Behavioural and neuropsychological evidence will be presented with respect to processes such as monitoring, response selection, task switching and interference control. |
