Term
short term memory
Definition
working memory, can hold information for a short time
Term
longterm memory
Definition
stores memory over long periods of time
Term
spacing effect
Definition
items that are repeated during list learning are remembered better if their two presentations are spread out over time (spaced presentation) than immediately one after the other (massed presentation)
Term
serial position effect
Definition

Term
mnemonic
Definition
often verbal, something such as a very short poem or a special word used to help a person remember something, particularly lists
Term
method of loci
Definition
a technique for memorizing many things and has been practiced since classical antiquity. It is a type of mnemonic link system based on places (loci, otherwise known as locations), used most often in cases where long lists of items are concerned. It was taught for many centuries as a part of the curriculum in schools, enabling an orator to easily remember a speech or students to easily remember many things at will
Term
peg-word system
Definition
a mnemonic technique for memorizing lists. It works by pre-memorizing a list of words that are easy to associate with the numbers they represent(1 to 10, 1-100, 1-1000, etc). Those objects form the "pegs" of the system. Then in the future, to rapidly memorize a list of arbitrary objects, each one is associated with the appropriate peg.
