Abstract:
By "attention" we refer to many kinds of selective processing. Psychological and physiological data are reviewed to show how visual attention emerges from three basic principles: competitive processing across multiple brain regions, bias by task context, and cross-region integration. More broadly, biased competition is doubtless characteristic of many processing systems, underlying the many varieties of "attention". Cross-system integration - in part guided by prefrontal cortex - produces the usual experience of coherent attention to the multiple aspects of a current task or line of thought.
