• what is the multi- store model

  it is a representation of how memory works in terms of three stores called the sensory register, short-term memory and long-term memory.

  it also describes how information is transferred from one store to another, what makes some memories last and what makes some disappear
• what is the sensory register

  stimulus from the environment passes into sensory register

  its a store for each of our five senses

  duration: less than half a second

  capacity: high

  coding: modality specific - two main stores: iconic (visual) echoic (auditory)

  transfer: information is passed on to the STM if attention is paid to it.
• what is short-term memory

  duration: 18 seconds

  capacity: on average 7+/-2

  coding: acoustic

  transfer: maintenance rehursal occurs when we repeat material, this keeps the information in our STM and if rehursed long enough it passes into LTM
• what is long-term memory

  store of information that has been rehearsed for a prolonged time

  duration: up to a lifetime

  capacity: unlimited

  coding: semantic

  when we want to recall information, it must be transferred back to the STM by retrieval.
