You're right on track (though I've barely done anything in this area). The common complaint against ACT-R was that it could never be reducible to a biological level. Since it started to introduce those NN components it's much further along in the last few years. That said, I think there's a way to come at multiple higher-level functions in one complex NN model if you respected anatomical localization of function (and perhaps quasi-modularity). Randy O'Reilly (http://psych.colorado.edu/~oreilly/ http://psych.colorado.edu/~oreilly/), part of the lead group that put this package together, has done some great work along these lines.
