MEMORY!
PSYC100
MIDTERM (for ch. 5):!
1. Study alcohol!
2. One to two qs on coffee!
!
Memory!
- ULTIMATELY: capacity to retain/retrieve info.!
!i. Memory isn't stored in ONE place, it's all over your brain (ie. remembering !
!childhood -- emotion, visuals, faces = all from diff. parts of brain)!
!ii. Memory = SENSORY info coming in!
!iii. Memory recording, doesn't make exact copies!
- Reconstruction of things that have already occurred; collaborative process!
!i. ie. memory w/ other ppl -- "remember yesterday at the movies...?"!
!ii. Interpretive: diff. ppl, diff. versions of the memory!
- w/o memory = inability to function properly!
!
Three Key Functions of Memory!
1. Encoding: transform what we perceive, think, or feel into an enduring memory!
!i. If not encoded, you don't remember it!
!ii. Memories made of new info and old info (are constructed)!
!iii. Three major ways to encode!
!!a) Elaborative/semantic encoding: relating new info to knowledge !!
!!already in memory (making connection)!
!!!1. Takes the longest to process!

!!b) Visual imagery encoding: storing new info thru mental ! ! !
!!pictures!
!!!1. Occipital lobe: memory retrieved by retrieving image of the new !
!!!knowledge you created!
!!!2. 2 diff. mental placeholders -- visual and verbal = more ways to !
!!!remember!
!!c) Organizational encoding: categorizing info according to relationships !
!!among series of items (AKA grouping info)!
!!!1. !
2. Storage: maintaining info in memory over time!
3. Retrieval: bringing to mind info that has been previously encoded and stored!
!
Encoding Con't!
- Codes DO NOT have to confirm to original stimulus (ie. you read words but don't store
images of letters); you meld the info in ways that make sense to you!
- Semantic encoding: lower left frontal lobe is active!
- Visual encoding: occipital lobe!
- Organizational encoding: upper left frontal lobe!
!
Memory Storage!
- Process of maintaining info in memory over time!
- Sensory memory: storage that holds sensory info for a few seconds or less (it goes
away so quickly because it doesn't matter -- things you remember are what's important)!
!i. Iconic memory: fast-decaying store of visual info (1 sec or less)!
!ii. Echoic memory: ...of auditory info (5 secs or less; ex. last words of a ! !
!sentence)!
!iii. immediate, initial recording of sensory info in the memory system -- entryway !
!to STM (short term mem.) or LTM (long term mem.)!
