What is the sensory register in the MSM?
Information from the environment enters through sensory memory (iconic for visual, echoic for auditory).
What are the capacity and duration of the sensory register?
It has a large capacity but a very short duration.
What are the characteristics of Short-Term Memory (STM) in the MSM?
Limited capacity (7±2 items), short duration (~18 seconds), mainly acoustic encoding.
What are the characteristics of Long-Term Memory (LTM) in the MSM?
Potentially unlimited capacity and duration, encoding is mostly semantic.
How is information transferred from STM to LTM in the MSM?
Through rehearsal, particularly maintenance rehearsal; elaborative rehearsal is needed for deeper encoding.
How does retrieval work in the MSM?
Information is transferred from LTM back to STM for recall.
What is the overall structure of the MSM?
It is a linear model where information flows in a fixed sequence.
What evidence supports separate STM and LTM stores?
The case study of HM, who could not transfer new info to LTM but had functioning STM.
How does HM’s case support the MSM?
It shows memory is stored in distinct locations, supporting the STM/LTM distinction.
What is a criticism of MSM regarding ecological validity?
Artificial tasks (e.g., trigrams used in studies) reduce ecological validity and may not represent real memory use.
What evidence suggests more than one type of STM?
The case of KF, who had poor STM for verbal but good for visual information.
How does KF’s case challenge the MSM?
It suggests STM is not a unitary store, supporting models like the Working Memory Model (WMM).
Is prolonged rehearsal necessary for LTM storage according to evidence?
No, Craik & Watkins (1973) found elaborative rehearsal (linking meaning) more important than repetition.
How does this challenge the MSM?
It shows MSM oversimplifies memory transfer and needs to include elaborative processes.
