[ACT-R-users] dissertations available on line

[Wayne Gray]

Greetings.

I am pleased to announce that three fairly recent to very recent 
dissertations are now available for downloading from my website.

The abstracts can be read at:

Wai-Tat Fu
http://www.rpi.edu/~grayw/pubs/papers/WFu2003_diss.html

Michael J. Schoelles
http://www.rpi.edu/~grayw/pubs/papers/Schoelles02_diss.html

Brian D. Ehret
http://www.rpi.edu/~grayw/pubs/papers/Ehret99_diss.html

All entail a substantial ACT-R modeling effort of dynamic 
environments. All include empirical test of the models.

Wai Tat's is the most recent and arguably entails the most complete 
exploration of ACT-R's conflict resolution mechanism (PG-C, learning 
P, learning C, credit assignment issues) that has been done to date. 
One ACTR model  with the same parameters (with one very reasonable 
exception) predicts the data from three experiments.

Michael Schoelles' entails one actr model of a complex dynamic task 
that was applied to four different interface conditions in two 
different experiments. This is arguably the largest and most dynamic 
ACTR 5 model to date.

Brian Ehret's shows that the normal ACTR mechanisms when used in a 
visual search task suffice to acquire location information. A very 
clever experimental paradigm and modeling effort.
