ABSTRACT
Perception comprises a range of different ways of informing ourselves about the environment for a variety of different purposes including understanding, recognition and prediction, aesthetic appreciation, and the control of action. One important tool adapting the visual system to different perceptual tasks is the set of control systems that we call attention. Attention can be allocated to different aspects of the environment and in different ways, ranging from the focused analysis of local conjunctions of features to the global registration of scene properties. I will describe the theoretical framework that I use and some research exploring the effects of these different ways of allocating attention to displays with multiple stimuli.
