[ACT-R-users] New ACTR publication

[Wayne Gray]

Greetings.

We are pleased to announce a new journal paper focusing on ACTR's 
expected value equation specifically but issues of credit assignment 
in modeling more generally.

Our Cognitive Systems Research journal paper is a substantial 
extension of the work presented at ICCM2004 and published in the 
proceedings. In addition to a greater discussion of the issues 
concerning binary vs scalar credit assignment, it included a 
discussion of three new variants on our actr model. Two of these 
variants are simulations that enable us to isolate the PG-C issues 
from any other problems that our inadequacies as modelers may have 
introduced to our models that might have contributed to the outcomes.

(Note that you will find other ACTR papers in this issue of CSRj.)

If you just have formalisms or a model you are doing "operations 
research" or" AI", if you just have data and a good study you are 
doing "experimental psychology", and if you just have ideas you are 
doing "philosophy" -- it takes all three to do cognitive science.
