Attention in time discrimination and reaction time.

This paper summarizes a year of research on attention. A theory of attention is developed which emphasize its temporal features. Attention is considered to be a central/neural control of information flow which is accomplished within the central nervous system. The hypothesis that it is all-or-none in nature is developed at length. The theory is framed in a sensory context and the experiments are done in that context. Alternative assumptions, which lead to different quantitative models of the theory are presented.
