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. |
