Question 1

process of memory

Answer 1

sensory info - encoding - storage - retrieval
encoding - info in converted for storage
storage - info is retained in memory
retrieval - info is recovered from memory when needed

Question 2

Atkinson-Shiffrin’s multistore model of memory

Answer 2

three stores of memory
- sensory memory
- short term memory
- long term memory

Question 3

multistore model

Answer 3

look at model
- sensory input - sensory m - (attention) - STM - (encoding) - (retrieval) - LTM
maintenance rehearsal and elaborative rehearsal
sensory m - info not attended to is lost rapidly
STM - unrehearsed info lost after 18-20 secs
LTM - some info lost over time

Question 4

sensory memory

Answer 4

entry point
exact copy (not encoded)
just long enough to attend to select info to be transferred to STM
- ionic memory
- echoic memory

Question 5

ionic and echoic memory

Answer 5

ionic - temporary store for info of a visual nature
echoic - temporary store for info of an auditory nature

Question 6

duration and capacity of sensory memory

Answer 6

duration- temporary and depends on type of sensory memory
Ionic - 0.3 sec, echoic - 3-4 sec
short so we are not overwhelmed, long enough to determine what to be transferred to STM
capacity - potentially unlimited

Question 7

short term memory

Answer 7

encoded version of sensory stimulus (not exact)
all thoughts, information and experiences that your aware of at any given moment
working memory
recieves info from 2 sources: SM and LTM (attention and retrieval)

Question 8

duration and capacity of STM and improvement methods

Answer 8

capacity- temporary (18-20 sec)
improvement: maintenance rehearsal and elaborative rehearsal
capacity - 7 items (+/- 2)
improvement - chunking
lost through decay (not being used) and displacement (being puched out)

Question 9

LTM duration and capacity

Answer 9

duration - potentially permanent/ long time
capacity - potentially unlimited

Question 10

types of LTM

Answer 10

EXPLICIT MEMORY
memory with awareness
- semantic memory - facts and knowledge
- episodic memory - personal experiences and events
IMPLICIT MEMORY
memory without awareness
- procedural memory - motor skills and actions
- classically conditioned memory - conditioned responses to conditioned stimuli
