Distractibility in Soar
Soar has an inherent
attentional mechanism that is based
on matching conditions of
productions in long-term memory
to the current elements in working memory. Normally, this results
in straightforward,
serial
problem solving behavior. However,
since any production that matches to the current working memory may
fire (i.e., the knowledge that is brought to bear is only indirectly
dependent upon the
goal context), productions
may fire that distract Soar from the current goal.
Not disregarding the context from which it was
distracted (i.e., the context is still present), Soar may continue
to follow this new path as long as additional
knowledge may be brought to bear it.
