Information Processing in Memory Tasks.
Johnston, William A.
The intensity of information processing engendered in different phases of standard memory tasks was examined in six experiments. Processing intensity was conceptualized as system capacity consumed, and was measured via a divided-attention procedure in which subjects performed a memory task and a simple reaction-time (RT) task concurrently. The more intensely a subject processed the memory information at any given point in the memory task, the less the residual capacity he could devote to the RT task, and the longer his RT to a signal occurring at that point should have been. Thus, RT served as an index of expended processing capacity. (EPC). Viewed collectively, the results shed considerable light on EPC during information input (list study) and output (recall). Input processing was enhanced by learning, list organization, input clarity, low information load, and an imagery memonic. Output processing was enhanced by learning, list organization, low information load, freedom of recall order, recency of input, and high item imagery. The results suggest ways in which learning and memory in practical situations can be conceptualized, diagnosed, and improved. (Author)
