Items in sensory memory fade rapidly and are replaced with new inputs. The persistence of information makes it available for further processing after a stimulus has ended or moved. There do not appear to be any design issues associated with this kind of memory. Memory It is also called working memory and acts as a scratch pad. It is memory for things that have never left consciousness, that are needed temporarily, and are forgotten.
People can appear to store more information in short-term memory by chunking it.
Recall from short-term memory is generally easy and but items are not recalled equally well. The primacy effect - things earlier in a sequence are more likely to be remembered. Recency effect - the most recently presented information is also more likely to be remembered. However, noise and other distractions interfere with rehearsal and can cause forgetting. Checklists are another way of helping people to retain items in short-term memory.
