Analogical transfer is the ability to transfer knowledge despite significant changes in
the surface features of a problem. In categorization, analogical transfer occurs if a
classification strategy learned with one set of stimuli can be transferred to a set of
novel, perceptually distinct stimuli. Three experiments investigated analogical
transfer in rule-based and information-integration categorization tasks. In rule-
based tasks, the optimal strategy is easy to describe verbally, whereas in
information-integration tasks accuracy is maximized only if information from two
or more stimulus dimensions is integrated in a way that is difficult or impossible to
describe verbally. In all three experiments, analogical transfer was nearly perfect in
the rule-based conditions, but no evidence for analogical transfer was found in the
information-integration conditions. These results were predicted a priori by the
COVIS theory of categorization.
