ACT-R model of spatial rotation

[Troy Kelley]

Hello,

I am attempting to program an ACT-R model of spatial rotation.  I have
some data where soldiers using a helmet mounted display do better on
post tests of spatial rotation when compared to the pre tests of spatial
rotation.  Apparently, they are practicing some of their spatial
rotation skills while using the helmet mounted display, so they end up
doing better on the post test of spatial rotation.

I am having a little trouble conceptualizing spatial rotation tasks as
productions.  I suppose I could have a group of "spatial skill
productions" which could include compare productions, align productions,
rotate X degrees productions and so on.  Some of which may be used
during the helmet mounted display tasks.  These productions would then
become stronger from repeated activation, and so the subjects would then
perform better during the spatial rotation test using these same
productions.

Does this sound like a good way to proceed or should I use another
strategy to represent this problem?  Any advice would be appreciated.

Troy
