STM – Primarily interference, although time plays a role

LTM – Almost entirely interference; It is usually a retrieval failure

There is no separate STM & LTM

The depth at which you process an incoming stimulus Determines how well it is remembered

Deeper processing leads to better memory

Levels of Processing: An Levels of Processing: An ExampleExample

A memory experiment where subjects process information in one of three ways:

Physical Appearance: “Is the word printed in capital letters?

Acoustic Processing: “Does the word rhyme with ‘pain’?”

Semantic Processing: “Does the word fit in the following sentence?:Bill ate the ________ for lunch yesterday.”
