[ACT-R-users] Silogism in ACT-R

[Stefani Nellen]

Repeating Dan Bothell's suggestion in an earlier reply to an email of  
yours, you might want to have a look at an ACT-R tutorial (some  
ressources can be found at
http://act-r.psy.cmu.edu/tutorials/
)
or, better yet, consider visiting this year's ACT-R Summer School (the  
announcement can be found here:
http://act-r.psy.cmu.edu/workshops/workshop-2004/ 
summerschool_2004_announce.htm
).

Many of your issues seem to be typical for people who are in the  
process of becoming acquainted with ACT-R, both on the theoretical and  
the practical/ implementation side, so the resources mentioned above  
might be rather helpful.

As for your question:
> Does ACT-R admits the creation of a new declarative chunk through the  
> combination of two or more preexisting declarative chunks, like in a  
> silogism?
That would be achieved by making the syllogism the goal and filling up  
the slots with chunks from the declarative memory, so in the end you  
have
=goal>
isa syllogism
premise1 =something
premise2 =something else
conclusion =yet something else

if you discard that goal, i.e. put a new goal in the goal buffer, the  
old goal becomes part of ACT-R's declarative memory.
Hope this helped,
Stefani
