ABSTRACT
We now turn to selective attention experiments using visual stimuli. There is such a large literature on visual attention that I have chosen to break it down into three chapters. To a great extent the issues raised in Chapter 2-what kinds of information can be used to guide selective attention, what limits selectivity, and where in the continuum of processing selection is made-will continue here. Other related issues concerning visual attention-what visual attention actually does, how it is directed, and whether it is directed to coordinates in space or to objects-will be addressed in Chapters 4 and 5.
