memory - the multistore model

what is the coding, capacity and duration of the sensory register

coding: modality specific

capacity: very large

duration: 0.25 seconds

what is the coding, capacity and duration of the short term memory

coding: acoustic form

capacity: limited 5-9 bits of information

duration: up to 18 seconds unless rehearsed

what is the coding, capacity and duration of the long term memory

coding: semantically

capacity: unlimited capacity

duration: lifetime

how is rehearsal important for the MSM

it acts as a buffer between sensory memory and LTM by maintaining incoming information within the STM

It enables information to be transferred to LTM

Who is HM and why is he relevant to the MSM

the case study of HM - had hippocampus removed which resulted in him not being able to form new long term memories but he can remember things from before his surgery, this indicates how there are different areas of the brain which are responsible for different types of memory

Who is KF and why is he relevant to the MSM

case of KF- brain damaged, caused his STM to be severely impaired and he could only recall two digits on the digit span test, however his LTM for events after the accident was fine, suggests LTM and STM are separate and distinct
