Thank you Coty -- Cleotilde Gonzalez Carnegie Mellon University Social and Decision Sciences 5000 Forbes Ave. Porter Hall 223C Pittsburgh PA 15213 tel: (412) 268-6242 fax: (412) 268-6938 ----- Carnegie Mellon University (CMU) invites applications for a Postdoctoral fellowship position in the area of cognitive modeling. This position is funded by the Army Research Laboratories under the "Advanced Decision Architectures" cooperative agreement. Our project, entitled "Cognitive Process Modeling and Measurement" intends to build cognitive models of decision making and learning in real-time tasks. Our project is currently funded for 5 years with a possible extension of 3 years. The ideal candidate will have a Ph.D. in Computer Science, Cognitive Science or equivalent with a strong LISP programming background and experience with ACT-R. We require working knowledge of programming languages, including but not limited to LISP, C++, or Prolog. Cognitive modeling experience is desired, but not required. We expect candidates to have strong research interests in all facets of cognitive modeling. Fellows are expected to conduct this research in collaboration with CMU faculty members and other partner institutions in the alliance team. The main duty of the post-doctoral fellow is to design, implement and refine cognitive models of decision makers in complex environments. Examples of real-time dynamic environments are: traders in financial markets, pilots in combat situations, doctors in emergency rooms, air-traffic controllers, managers in complex manufacturing settings, etc. Other responsibilities include creating performance measures and tools for validation of model performance and support of empirical testing with actual decision makers. Appointment will pay highly competitive rates based on background and experience. Anticipated start date is October 1, 2001. Applicants should send curriculum vitae, relevant journal articles, a letter of research interests, and three reference letters to: Dr. Cleotilde Gonzalez, Social and Decision Sciences, Carnegie Mellon University, 5000 Forbes Ave. Pittsburgh, PA 15213. Electronic applications are encouraged. Please send electronic documents (Word, Pdf) to: conzalez at andrew.cmu.edu. From fjl at cmu.edu Sun Jul 8 16:32:46 2001 From: fjl at cmu.edu (Frank J.

ACT-R 5.0 will allow those operations within productions automatically. In a manner similar to the negation test one can now use <, <=, >, or >= as slot test modifiers when the values are numbers. The sperling model in unit 3 uses them if you want to see an example of their use.

I know many of you are probably using the official ACT-R Environment running it on Apple and Wintel machines with Allegro Common Lisp etc, but perhaps some of you who are running ACT-R on Unix / Linux with free CMU CL or CLISP may find my little program useful. The code can be downloaded here: http://www.cs.nott.ac.uk/~rvb/lisp/ACT-R-Vision/ACT-R-Vision.lisp or a tar ball: http://www.cs.nott.ac.uk/~rvb/lisp/ACT-R-Vision/ACT-R-Vision.tar.gz The program uses Garnet GUI library, so you will also need to install and load Garnet to use ACT-R-Vision. Load both Garnet and ACT-R before loading ACT-R-Vision.lisp (you may also edit the appropriate load commands in the code). The program is rather simple and many tools I was thinking about have not been implemented simply because of the lack of time, but still it gives much more feedback about ACT-R model then typing commands in Lisp evaluator. So far I have tested the program on two Linux machines and on SUN Sparcstation, all running CMU Common Lisp and Garnet 3.0. It seemed to run without problems, but I am sure there will be many. I welcome all comments and bug reports.

I'll send a summary of the responses to the mailing list so everyone can see the results, and all replies will be treated confidentially. Thank you in advance, Dan ################### ACT-R User Survey ############################## 1. What operating system do you use? 2. What Lisp do you use? 3.

It's really more of a convenience feature than a theory based model of comparison. There were a bunch of models that had !eval!'s in there to do that type of thing so it seemed reasonable to provide an easier way (particularly when using the numerical coordinates provided by the visual interface). Many modelers are concerned more with the higher level effects and don't need (or want) to have to do everything down to that level of detail. However, if that's important to your task and you need to reproduce those effects then it probably isn't the right solution.
