Flashcards in The Multi-Store Model of Memory (Atkinson & Shiffrin, 1986) Deck (24):
What happens at the sensory register?
information comes in but is lost if not paid attention to
How does information move from the sensory register to short term memory?
by being paid attention to
What must be done for information to stay in short term memory?
How might information be lost at short term memory?
if it is not rehearsed
What must happen in order to move information from short term to long term memory?
- advice to students
- knowledge for psychologists
- people with memory loss
- people who struggle to remember information
What is trace decay and where does it take place?
trace decay can occur in long term memory whereby memories decay over time
Sensory register: encoding
modality specific (from senses)
Short term: encoding
does not depend on the input
Long term: encoding
depends on rehearsal process and pre-existing knowledge
Sensory register: storage duration
a few hundred milliseconds until paid attention to
Short term: storage duration
Long term: storage duration
potentially a lifetime
Short term: storage capacity
5-8 items of information (7+/-2)
Long term: storage capacity
Sensory register: forgetting
information is forgotten unless paid attention to
Short term: forgetting
only if rehearsal doesn't occur
Short term: retrieval
rapid scan of stored information (rehearsal required to maintain information in this store)
Long term: retrieval
linked to sensory modalities
Evaluation: supporting study
Glanzer & Cunitz (1966) - primary effect (LTM) and recency effect (STM)
Good - lab conditions means high reliability
Bad - lab conditions means low ecological validity
Evaluation: opposing studies
Clive Wearing - impaired STM, can't transfer information to LTM - memory is more complex than described in MSM
Evaluation: different theories
Baddeley & Hitch (1974) working memory model - builds on the short term memory information provided in MSM
