Attention

The subject of attention has until recently been largely confined to the domain of experimental psychology. Researchers have sought to measure and explain such things as the selective capacity of attention, its range and span, the number of objects that it can appreciate simultaneously, and the muscle contractions associated with attentional efforts. Such work has been carried on amid considerable disagreement over basic definitions of the phenomenon of attention itself. ~ from the articlehttps://scholar.dominican.edu/books/1102/thumbnail.jp
