how does the sensory memory code ? (3)
- according to senses
- iconically
- echoically
what is the capacity of our sensory memory ?
unlimited
what is the duration of the sensory memory ?
milliseconds
how does our LTM code ?
- semantically

who carried out research on coding for our LTM ?
Alan Baddley
explain the research carried out for the coding of our LTM (3)
- shown a list of accoustically and semantically similar + disimilar words
- recall after 20 mins
- found that we do worse on semantically similar words
describe research carried out for the duration of our LTM (8)
- 392 pptnts ( 17 - 74yrs)
- year books of pptnts
- photo recognition test ( 50 pics)
- free recall test - of grad class
- photo rec test - those who garduated 15 yrs ago = 90% accuracy
- those who grad 48 yrs ago = 70%
- free recall: 15 years = 60%
- 48yrs = 30%
what was the % accuracy for the free recall test of those who graduated 15 years ago ?
60%
what was the % accuracy for the free recall test of those who graduated 48 years ago ?
30%
what was the % accuracy for the photo recognition test of those who graduated 15 years ago ?
90%
what was the % accuracy for the photo recognitionl test of those who graduated 48 years ago ?
70%
what are the 3 types of LTM (3)
- episodic
- semantic
- procedural
explain the features of episodic memory (3)
- recall events
- time stamped
- must make concious effort to recall
which part of the brain is resposible for episodic memory
hippocampus
give an example of an episodic memory
your last meal
describe the features of your semantic memory (3)
- knowledge of the world
- not time stamped
- make concious effort to recall
which part of the brain is responsibel for our semantic memory ?
hippocampus
give an example of semantic memory
defenetion of LTM
describe the features of our procedural momory (3)
- memory for skills
- not time stamped
- dont have to make concious effort to recall
which part of the brain is responsible for our procedural memory ?
motor cortex
give an example of our procedural memory
- driving a car
