Data 'chunks' are easier to remember

This might have something to do with [cached thoughts](http://www.overcomingbias.com/2007/10/cached-thoughts.html).

I'm wondering how exactly the cache works. Is it like a-b-c, where the brain remembers that a is 443, b is 297, and c is 9960? Or does the last number in each chunk give you a clue as to the address of the next chunk? (example: after reading the 3 in 443, my brain says "Oh, you might be needing this" and gives me the next three numbers all at once.) Right now I'm leaning towards the second one.

in short, it's called chunking. most introductory psych classes cover this, i'm surprised that john hopkins is spending their time regurgitating basic stuff like this.
