Just got word, the post-doc at NRL is good to go. One less thing to have to worry about. But then I realized, oh crap, I’ll be jumping in immediately after my defense, which is already looking like it will have to be pushed back. But, Greg is cool with me taking a little break in between. Thank god.. that little bit of breathing room should make this much less of a hellish month.
new versions of jACT-R, IDE, and ACT-R/S have been posted. I will be putting together a screencast soon to illustrate how to set up automatic model fit calculations and parameter space searches.
Gotta love cognitive modeling. I’ve been looking at the parameter sensitivity on both egocentric and jrd pointing. The point is to fit the set size 4 and then apply it to set size 8 (I ditched 6 in the analysis, so I’ll ignore them again here).
I had a really nice fit (relatively) with common parameter values. RMSE combined (ego/jrd) of 0.9s, which is much smaller than the standard deviation of either ego or jrd pointing responses (error is in abeyance for now).
So I ran some bulk iterations. Damnit. The performance is dependent upon the activation balance between visually attended and spatially updated representations. Well, the random assignment of configurations and trials within a configuration is sufficient to blow that single test out of the water. Bleck. So, I guess I’m going to do this parameter search with bulk runs.
Ha!
