The importance of being visible: On the role of attention in a mind viewed as an anarchic intelligence system i basic tenets

Abstract

This paper describes an attempt to view attention from the perspective of a pluralistic concept of information processing in the mind. The mind is likened to an anarchic intelligence system. It is assumed to comprise of a set of processing entities called modules that may be active in parellel. Their activation is externally driven, and their operation is not controlled by any other module. Cooperating among modules is often required for achieving goals. Cooperation calls for communication. Attention is assumed to regulate only the communication among modules. It exerts attentional emphasis by making the output of a to-be-attended module available for a maximal number of other modules, while limiting the ability of de-emphasised modules to disseminate their output. This is achieved by a mechanism called decoupling that controls the connections between modules. The control of decoupling that is required for attentional emphasis is associated with an aversive phenomenal aspect that is usually called effort. Awareness of a piece of information amounts to the visibility of that information among various modules.
