ABSTRACT
So far, far, we have seen how different different selective attention experiments, by virtue of their design, might be considered to be measuring, manipulating, or observing different varieties of attention. On the small scale some answers may have been found: for example, the minimum width of the spotlight (in certain conditions); stimulus dimensions which facilitate selectivity (in certain conditions); how the perceptual display is segregated (in particular conditions) and so on. In later chapters, the difficulty of combining tasks or dividing attention will be discussed and again some answers will be offered.
