It can also be considered a component of your brain's executive control and manipulation of information. Size of chunks depends on your organizational plan for the information. Each kind of memory is stored in a different way in the brain. When we do tests of memory, how people perform is affected by how much they have forgotten and how well they can retrieve the information. If another stimulus appears after the information that is to be remembered, retrieval of that information can be diminished or completely lost.

Then, when you memorize the same thing for the upper extremity, it interferes with retrieving the lower extremity information because the information is so similar. The Slope of the lines represent how much more time in takes to search your memory as the amount of information to search increases. If you have mild cognitive impairment, your line intercepts at a higher point than is you don't. If the info is easy. If there are time-consuming comparisons to be made or if you don't make comparisons and searches quickly.
