1
Q

Multi store model

A

Memory a flow of information through information processing system
System divided into a series of stages as information passes from one store to another in a fixed sequence
Each stage has constraints in terms of capacity duration and encoding

Short term to long term by rehearsal

Q

Bahrick et al (1975)

A

LTM duration
Names and faces of high school classmates
400pps ages 17-74
Accuracy 80% within 15 years
78% 48 + years
Memory deteriorates but names and faces are resilient

Q

Conclusion

A

Application
How best to memories things for STM and LTM
What needs to be revisited and how often to relearn things
Explains why people have different memories of things as they have to pay attention to the specific thing for it to be in their memory

Q

Negatives

A

Reductionist
Simplifys explanations (non holistic approach)
Ignores other factors (WMM) can’t explain things like how KF lost STM but could still make new LTM memories
Based on lab experiments (lacks ecological validity) ( Peterson and Peterson trigrams is very unrealistic )

Q

Describe multi store model

A

Information primarily enters the system through a
sensory experience and into the sensory register which is
modality specific (1). Information is then passed to short
term memory where it can be held for around 18-30
seconds before it decays (1). If this data is rehearsed to
maintain the information it can be transferred to long
term memory (1). Long-term memory is said to have a
potentially infinite capacity and duration (1).
