Why is our capacity of working memory so large
... Working memory requires the ability to hold information, or references to information in long-term memory, over a short period of time. Hence, a capacity limit of short term memory would support the limited capacity of working memory. The neurophysiological correlates and mechanisms of short-term me ...
