[ACT-R-users] Preliminary workshop schedule

[Niels Taatgen]

I hereby send you a preliminary schedule for the ACT-R workshop. Note  
that this means that we can still shift some things around if needed.  
If you have submitted a talk, make sure it is on the schedule and  
send me an email a.s.p. if you are not on there or if I have  
misspelled your title or name.

We will make informal proceedings of the workshop. For every talk we  
have up to six pages in the proceedings, which you can fill with your  
abstract, your slides, a paper, or any combination of these. Send me  
a pdf-file (formatted for US-letter) of your proceedings contribution  
on or before Monday 17 July, and give it your name as file-name  
(e.g., anderson.pdf, anderson1.pdf and anderson2.pdf if you have  
multiple contributions).

I look forward to meeting you all at the workshop!

Niels Taatgen
