ABSTRACT

This chapter reviews some of the major computational models of visual attention and highlights how they help to clarify concepts in psychological theories. To do this we focus on some of the major issues and experimental paradigms that have influenced psychologists, including space-vs. objectbased attention, stimulus filtering tasks, and visual search. We also discuss how the models can be used to simulate neuropsychological disorders of visual cognition, including agnosia and neglect-disorders that themselves highlight particular theoretical issues, such as the role of parallel grouping processes in vision, the relations between attention and spatial representation, and the interaction between bottom-up and top-down factors in selection. We conclude by evaluating the contribution of the modelling process to understanding cognition.
