THE MULTI-STORE MODEL OF MEMORY

Question 1

Burger for sensory register (Multi-store model of memory)

Answer 1

B: Sensory register has a large capacity but a very short duration (milliseconds).
U: It briefly holds information from the environment, allowing for initial processing.
R: Supported by studies showing how sensory information is processed; attention is crucial for transfer.
G: Strength: Highlights the initial stage of memory processing.
E: Essential for understanding how we filter and prioritize sensory information.
R: Weakness: Too simplistic; doesn’t account for different sensory modalities and their processing.

Question 2

burger for short term memory
(Multi-store model of memory)

Answer 2

B: STM has a limited capacity of about 5 items or chunks and a short duration (a few minutes) unless rehearsed.
U: Information in STM is vulnerable to decay and interference, necessitating active maintenance.
R: Supported by studies like Jacobs (digit span), Miller (chunking), and Peterson and Peterson (decay).
G: Strength: Empirical support from various lab studies strengthens the model.
E: Important for understanding how information is temporarily stored and manipulated.
R: Weakness: STM is not a single unitary store; it may involve different processes and types of information.

Question 3

burger for Long term memory
(Multi-store model of memory)

Answer 3

B: LTM has a potentially unlimited capacity and duration, with forgetting possibly due to lack of accessibility.
U: Information is stored long-term and can be retrieved, but access may be impaired by various factors.
R: Supported by brain scan studies (Beardsley linked LTM to the hippocampus) and case studies like HM (Scoville and Milner).
G: Strength: Evidence from neuroscience strengthens the understanding of memory processes.
E: Crucial for understanding the complexity of memory storage and retrieval.
R: Weakness: The model is overly simplistic; it doesn’t account for the nuances of memory encoding and retrieval processes.
