The primary purpose of these studies was to explore the question of whether a performance which is critically dependent upon short-term memory breaks down with input rate increases when performance is measured in absolute terms. Since, for any fixed input time, increases in quantity of information represent increases in the input rate, a breakdown, if demonstrated, can be thought of as the result of exceeding the memory storage rate. Thus, it could be asked, given such a breakdown, whether the absolute performance level might not be increased by reducing the informational input load. In simpler terms, will S report more correct items when there is less to be recalled than when there is too much to be recalled. The studies were set up with these questions in mind.
