		<abstract>This work describes a framework for dealing with attention and categorization using a robot platform consisting of an articulated stereo-head with four degrees of freedom (pan, tilt, left verge, and right verge). As a practical result of this development, the system can select a region of interest, perform shifts of attention involving saccadic movement, perform and efficient feature extraction and identification/recognition, incrementally construct a world map, and keep this map consistent with a current perception of the world. Another important result for the attentional mechanism is that the system is capable to visit all regions of its restricted world, selecting on region at a time according to a salience map. For identification, the system starts without any knowledge of the environment and increases its knowledge base (associative memory) as necessary to deal with a current set of objects.</abstract>
