Abstract

A computational model of sequence learning is described that is based on pairwise associations and generalization.  Simulations by the model predicted that rats should learn a long monotonic pattern of food quantities better than a nonmonotonic pattern, as predicted by rule-learning theory, and that they should learn a short nonmonotonic pattern with highly discriminable elements better than one with less discriminable elements, as predicted by interitem association theory.  In two other studies, the model also simulated behavioral "rule generalization," "extrapolation," and associative transfer data motivated by both rule-learning and associative perspectives.  Although these simulations do not rule out the possibility that rats can use rule-induction to learn serial patterns, they show that a simple associative model can account for the classical behavioral studies implicating rule learning in reward magnitude serial-pattern learning. 

 

Congratulations, Doug!
