attention: to get info from the sensory memory to the STM
rehearsal: to keep info in the STM or transfer it to the LTM
Atkinson and shiffrin (1968,1971) describe how info flows through the memory system. the model suggests that memory is made up of three stores linked by processing
What is the term for the register based on the sense it is used to?
Modality specific
What is the duration of short-term memory?
9 pieces of information
What is the duration of long-term memory?
Potentially infinite
How long does echoic memory last?
Approximately 2 seconds
What does the Murdock serial position curve (1962) suggest?
Words at the start and end are recalled better
What are the strengths and limitations of the Multi-Store Model (MSM)?
Strengths:
Supported by Clive Wearing's case
Distinction between STM and LTM

Limitations:
KF's case suggests STM is complex
Only explains one type of rehearsal
Uses artificial materials in studies
Lacks external validity
What type of rehearsal does the MSM describe?
Maintenance rehearsal
What is elaborative rehearsal?
Linking information to existing knowledge
Why is the use of artificial materials a limitation of the MSM?
It lacks external validity in real-life situations
What did Peterson and Peterson (1959) use in their study?
Consonant syllables with no meaning
What is the main finding from Clive Wearing's case?
His STM is intact, but LTM is damaged
What does KF's case suggest about STM?
STM is subdivided and complex
How does the MSM fail to account for different types of rehearsal?
It only describes maintenance rehearsal
What is the implication of the MSM's lack of external validity?
Findings may not apply to everyday memory
Who conducted the study that reported on KF's case?
Shallice and Warrington
What does the term "displacement" refer to in memory?
New information replaces old information
How does the MSM explain the process of memory formation?
Information passes through registers to LTM
