The Multi-Store Model of Memory- AO1
Atkinson and Shiffrin (1968) proposed one of the earliest models of memory.
They suggested that memory is made up of three compounds, that memories are
formed sequentially and that information is passed from one component to the next
in a linear fashion. Rehearsal

How do memories decay?
Interference:
Proactive interference- when something learnt earlier interferes with the current
learning.
Retrospective interference- when something learnt later gets in the way of
something learnt previously.
