Encoding: the processing of _____________________________________
Storage: the retention of ____________________________________
Retrieval: process of getting information _____________________________

Maintenance Rehearsal

Long term memory: Once information passes from sensory to working memory, it can be encoded into
long term memory.

 Explicit Memory
 memory of facts and experiences that one can consciously know and declare

process explicit memories for storage
 Implicit Memory
 retention without ___________________________________
 motor and cognitive skills

Retrieval- Getting Information Out
 Recall
- ability to retrieve info
______________________________________________________________________-like fill in the
blank test
 Recognition
- ability to identify
_______________________________________________________________________
Retrieval
 Relearning
 amount of time saved when
_______________________________________________________
 Priming
 activation, often unconsciously, of particular __________________________________
Retrieval Cues
 Reminders of information to prime memory
 Guides to where to look for info

we cannot attend to everything in our environment

- disruptive effect of ________________________________________________

 Source Amnesia
 _____________________________________________________that we experienced,
heard about, read about, or imagined (misattribution)

Improve your Memory
 Study repeatedly to ________________
 Spend more time _______________________ or actively thinking about the material
 Make material ________________________________________________
 Use mnemonic devices
 associate with peg words- something already stored
 make up story

 Activate retrieval cues: mentally recreate _______________________________
 Recall events while they are fresh________________________________________________________
 Minimize interference
 Test your own knowledge
- rehearse
- determine what you do not yet know
