who was the multi store model proposed by
atkinson and shiffrin
describe the sensory register
- information enters from our environment, through our senses
- information is encoded visually and acoustically
- unlimited capacity
- brief duration (seconds)
how is information forgotten from the sensory register?
if no attention is payed to it
describe the short term memory store
- information encoded acoustically
- around 7 chunk capacity
- 18 second duration
how is information forgotten from STM?
if it hasn’t been rehearsed
describe the long term memory store
- information encoded semantically
- lifetime duration
- unlimited capacity
how is information forgotten from LTM
decay or interference
what is the recency effect?
having better recall for items at the end of a list as they haven’t been displaced from STM yet as they have been there less time
what is the primacy effect?
having better recall for items at the start of a list as they have been encoded into LTM already so they are available for recall
why are items decayed from memory?
a lack of available space/capacity
what did miller propose about chunking?
more information is recalled by grouping similar items together to reduce a larger capacity
