Psychology: An Introduction Charles A. Morris & Albert A. Maisto © 2005 Prentice Hall Long-Term Memory Everything that is learned is stored in long- term memory Capacity of long-term memory Vast amounts of information may be stored for many years No known limits to capacity

Psychology: An Introduction Charles A. Morris & Albert A. Maisto © 2005 Prentice Hall Encoding in Long-Term Memory Most information is encoded in terms of meaning Some information is stored verbatim Some information is coded in terms of nonverbal images Research has shown that memory for visually encoded information is better than phonologically encoded information Hence concept maps that create a visual

Psychology: An Introduction Charles A. Morris & Albert A. Maisto © 2005 Prentice Hall Maintaining Long-Term Memory Rote rehearsal Repetition can result in long-term memory Only effective if there is intent to learn material Examples when there is no intent: What color is on top on a stop light? How many sides does a stop sign have? Which color is the top stripe on the US Flag? What direction is Lincoln facing on the five dollar bill?

Psychology: An Introduction Charles A. Morris & Albert A. Maisto © 2005 Prentice Hall Concept Map? Dual coding – images are encoded both visually and phonologically Chunking - Organizing information so that it fits into meaningful units. This gets it into STM. Listen to music but not the lyrics! Domain specific working memory systems! LTM storage is by meaning Overcomes serial positioning effect Forces elaborative rehearsal Creates Psychology schemata (categories => hierarchies)
