a multilevel classification system based on common properties among items -can improve recall dramatically

Why do researchers even believe there are different types of memory stores

amnesia

What is a schema?

an organized cluster of knowledge about a particular object or event abstracted from previous experience with the object or event

use rehearsal

What is retroactive interference?

when newly-learned information interferes with you remembering previous information (e.g., perhaps the French you are learning now is making it difficult to remember the Spanish you learned from before)
