Managing Attention by Preparing to Forget
In dynamic task environments, human operators must update their memory for what is true of the current situation. This updating depends on forgetting old information, and this forgetting in turn places constraints on how an item is encoded in the first place - the cognitive system must prepare to forget. Functional decay theory accurately predicts how long this preparation takes - concentrated use of an item for about 5 set requires an additional 1 set for initial encoding. This quantitative prediction illustrates the potential of functional decay theory for evaluating cognitive workload.Download Paper Back to Home << Publications Visitors since 2004.12.08:
