[ACT-R-users] ACT-R-users Digest, Vol 51, Issue 8

Wed Oct 21 21:26:18 EDT 2009

Hi,

I am attempting to relate how close to Bayesian theory ACT-R is--I know that
the Bayesian roots of ACT-R are referenced somehow by Anderson in *Rules of
the Mind* --I am saying this in the context that I have seen *Rules of the
Mind* referenced (I thought) in conjunction with a Bayesian version of
ACT-R, but in truth  I am frustrated in that I can't get access to this book
right now and I could really use it to clarify my understanding of this.

Is DM (and / or Procedural memory) inherently Bayesian in nature?
Can either be characterized in that manner or has it been morphed to an
extent away from this?  The basis of my question is that I am unusure if the
information is related in an acyclic fashion in all instances when it is put
into the declarative memory.  This would seem to be a sticking point if it
was.

Dan, is there a definative answer to this anywhere?  Can you help?
