MEMORY ( MSM)

Question 1

Identify the different stores in the MSM

Answer 1

the sensory memory , short term memory and long term memory

Question 2

How is information transferred to STM from the Sensory Memory

Answer 2

by paying attention

Question 8

Evaluate the MSM

Answer 8

STRENGTHS :

Brain studies : HM after surgery to remove the hippocampus from both sides in order to reduce epilepsy . He could not form new LTM but had intact STM supporting the separation of STM and LTM as HM could not transfer information from his STM to LTM.

LIMITATIONS

Oversimplification : MSM treats the STM and LTM as unitary stores , but evidence suggests they’re more complex . Patient KF had poor STM for verbal info but good visual info, showing that STM isn’t a single store.

Rehearsal isn’t the only way to transfer to LTM . According to MSM , rehearsal is the key to transferring information from STM to LTM however researchers argue that depth of processing matters more than repetition , information processed semantically goes to LTM without rehearsal
