Abstract:
This study investigates processing and storage in the brain using a
priming task. We model a priming task with a relaxation neural network
- the Coulomb Energy Network. The network's performance on a
fragment-completion task is assessed by storing a set of memories into
the network and, subsequently, testing its completion performance.  It
has been claimed that the findings of stochastic independence on
repeated fragment completion imply noninteracting memory traces. We
nevertheless model memory in a way in which all traces embodying a
single representation interact and find stochastic independence when
the memories in the network are densely packed.  Dependence between
priming fragments can be obtained, but only when the memories are
sparsely packed.  We conclude that independence on repeated fragment
completion does not necessarily imply that the underlying memory traces
are noninteracting memory traces.
