In two experiments, recognition accuracy was compared between subjects who made frequency judgments and subjects who made recognition judgments. Results indicate that at least partially different information in memory is evaluated when judging frequency than when making recognition judgments and that this information facilitates recognition…

In recent years several models of human-information processing have been proposed in which the central component is a limited-capacity processing system. One line of research has focused on the question of which stages in the processing sequence require capacity in this system. This research is concerned with time and capacity demands in…
