Capacity = 3 or 4 chunks at a time Imagination The World Working Memory Long-term Memory When we think about things, trying to make sense of them, information is temporarily held in working memory. Only three or four chunks of visual information can be stored in working memory at any one time. Information that comes in through our eyes or that is retrieved from long-term memory in the moment of thought is extremely limited in capacity. When you release information from working memory, it can take one of two possible routes on its way out: 1) it can be stored permanently in long-term memory by means of a rehearsal process that we call memorization, or 2) it can simply be forgotten.
External aids can augment memory. To compare facts, you must hold them in working memory simultaneously. Because we can hold so little in working memory at any one time, however, to do analysis effectively, we must rely on external aids to memory. This is an ideal job for a computer. Even a piece of paper that you jot down notes on to keep track of information as you’re analyzing data is an external memory aid that is quite powerful despite being low-tech. A computer running properly designed software, however, can augment our ability to think about information much better than pencil and paper.
