Basic response time tools for studying general processing capacity in attention, perception, and cognition

One of the more important constructs in the study of attention, perception, and cognition is that of capacity. The authors reviewed some of the common meanings of this construct and proposed a more precise treatment. They sho wed how the distribution of response times can be used to derive measures o f process capacity and to further illustrate how these measures can be used to address important hypotheses in cognition.
