Q
What is the diagram
A
IDK BUT GO CHECK IT
2
Q
Strengths of the model
A
- large base of research that supports the idea of distinct STM and LTM systems. For example brain damaged case study patient KF’s STM was impaired following a motorcycle accident, but his LTM remained intact
- It makes sense that memories in the LTM are encoded semantically - i.e. you might recall the general message put across in a political speech, rather than all of the words as they were heard.
• The MSM was a pioneering model of memory that inspired further research and consequently other influential models, such as the Working Memory Model.

Q
Weaknesses of the model
A
- Some research into STM duration has low ecological validity, as the stimuli participants were asked to remember bear little resemblance to items learned in real life, e.g. Peterson and Peterson (1959) used nonsense trigrams such as ‘XQF’ to investigate STM duration.
• The model is arguably over-simplified, as evidence suggests that there are multiple short and long-term memory stores, e.g. ‘LTM’ can be split into Episodic, Procedural and Semantic memory.
• It does not make much sense to think of procedural memory (a type of LTM) as being encoded semantically, i.e. knowing how to ride a bike through its meaning.
• It is only assumed that LTM has an unlimited capacity, as research has been unable to measure this accurately.
4
Q
What is encoding?
A
The process of coding information so that it can be stored into memory. (Eg by giving words meanings)
5
Q
What is capacity
A
How much information can be held in the memory store
6
Q
Duration meaning
A
The amount of time the information is held in the memory store
7
Q
Sensory memory duration, capacity and encoding
A
<2 seconds, very large capacity, sense specific
8
Q
STM duration, capacity and encoding
A
<30 seconds, 5-9, auditory or phonemic
9
Q
LTM duration, capacity and encoding
A
Unlimited, unlimited, semantic (can be visual auditory)

A
Atkinson and Shiffrin
