MULTI-STORE MODEL OF MEMORY: Atkinson & Shiffrin (1968)

What does Murdock’s study demonstrate about rehearsal?

Rehearsal can lead to encoding into long-term memory (LTM) and highlights the limited space and duration of short-term memory (STM).

What was the significance of Clive Wearing's condition for memory studies?

Clive Wearing had a destroyed hippocampus, showing that STM and LTM are different; he had no STM but retained some LTM.

What types of LTM did Clive Wearing retain?

He retained semantic and procedural memory but lacked episodic memory.

What is a limitation of the Multi-Store Model (MSM) regarding memory tasks?

Artificial memory tasks, like nonsense syllables, do not accurately reflect how we use memory in real life.

How is information coded in Sensory Memory?

Encoded through the same format it is received, with a duration of less than a second.

What are the key characteristics of Short-Term Memory (STM)?

STM is encoded acoustically, has a capacity of 7 ± 2 items, and a duration of 20 to 30 seconds unless rehearsed.

What are the key characteristics of Long-Term Memory (LTM)?

LTM is encoded semantically, has an unlimited capacity, and can last a lifetime.
