In four experiments, I examined how a property in one concept is trans
ferred to a second concept during conceptual combination. The results
suggest that people instantiate properties: that is, they use a specif
ic representation of a property in the modifier concept to construct a
new version of that property that is specific to the combination. If
people are instantiating properties, then the modifier property should
match its counterpart in the combination to the extent that the modif
ier and head noun are similar. This observation leads to a variety of
predictions (supported by the experiments) about interpretations of si
milar and dissimilar combinations and about plausibility, preference,
and similarity judgments associated with such interpretations. The res
ults argue against an alternative view of transfer that posits that, i
n general, abstract representations of properties are copied from one
concept to another. In this paper, I describe various processing accou
nts of instantiation and discuss the implications of the instantiation
view for theories of metaphor, conceptual combination, and induction.
