How is memory like a computer?
Information Processing
Three stage model of memory:

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

Working Memory

Short-term memory

Long-term Memory

Maintenance Rehearsal

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

o Unlimited capacity
o Duration-thought by some to be permanent

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

process explicit memories for storage
 Implicit Memory
 retention without ___________________________________

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

- disruptive effect of ________________________________________________

 Source Amnesia
 _____________________________________________________that we experienced,

Improve your Memory
 Study repeatedly to ________________

 Recall events while they are fresh________________________________________________________
 Minimize interference
 Test your own knowledge
- rehearse
- determine what you do not yet know
