Question
Some theories hold that short-term memory consists of a fixed number of slots. For
those theories, the capacity of short-term memory was once thought to be 7 plus-or-
minus 2 items. However, that estimate has been revised. How and why?
O The estimate has been revised downwards to 1 or 2 items because that is how many items
people can recall from short-term memory when they are given meaningless items to rehearse
O The capacity of short-term memory is now thought to be unlimited if the words are
meaningful because understanding is the same as encoding into short-term memory
The estimate has been revised upwards to 10 plus-or-minus 3 items because people are able
to chunk items more than was previously believed
O The estimate has been revised downwards to 3 or 4 items because that is how many items
people can recall from short-term memory when they are unable to chunk the information
