The organization of training is an important determinant of how well subjec
ts learn a cognitive task. To understand why different training schedules p
roduce different learned performance, we used a hippocampal model to compar
e three training paradigms for the hippocampally dependent cognitive task c
alled transverse patterning. Simulations reproduce training effects seen in
humans and rats. As in behavioral studies, progressive training produces r
obust learning while random training renders the task essentially unlearnab
le. The simulations predict that a third training paradigm, called staged l
earning, will produce more robust learning on average than the progressive
paradigm used in published behavioral studies. Possible mechanisms underlyi
ng performance differences between paradigms are investigated and discussed
