Memory Stages
Sensory register or memory Immediate memory (short term memory, retention span) Long-term memory
Sensory register or memory
where incoming information is retained
Immediate Memory (short term memory, retention span)
has limited capacity and decays within a few seconds unless rehearsed. Working memory
Long term memory
large capacity, where information is stored
Long term memory categories
Recent Memory

Retrospective Memory
Relates to past experience
Retrospective Memory Types
