We have a new paper out that represents a collaboration with Judy Stamps and Pete Biro, and Pete's student David. In this follow-up to our previous paper on learning, we test Bayesian updating theory to ask: can genetic differences in learning be predicted a priori?  We find that the answer is YES!
