Theoretical principles
Long-term memory can exist in various states
of activation including (at least):
inactive,
primed (ready for use), and
active (immediately accessible).
Memory is associative and productive.
Activating one element leads, with some probability,
to the activation of associated elements.
The activation of a memory often contains data,
reasoning elements, and mappings
of the memory elements onto input structures.
Activation and association are context dependent.
What is activated and subsequent activations
depend on the context, both external and internal
(other activated elements).
