Résumé
After reviewing six senses of abstraction, this article focuses on abstractions that take the form of summary
representations. Three central properties of these abstractions are established: (i) type–token interpretation;
(ii) structured representation; and (iii) dynamic realization. Traditional theories of representation
handle interpretation and structure well but are not sufficiently dynamical. Conversely, connectionist
theories are exquisitely dynamic but have problems with structure. Perceptual symbol systems offer an
approach that implements all three properties naturally. Within this framework, a loose collection of property
and relation simulators develops to represent abstractions. Type–token interpretation results from
binding a property simulator to a region of a perceived or simulated category member. Structured representation
results from binding a configuration of property and relation simulators to multiple regions
in an integrated manner. Dynamic realization results from applying different subsets of property and
relation simulators to category members on different occasions. From this standpoint, there are no permanent
or complete abstractions of a category in memory. Instead, abstraction is the skill to construct temporary
online interpretations of a category’s members. Although an infinite number of abstractions are
possible, attractors develop for habitual approaches to interpretation. This approach provides new ways of
thinking about abstraction phenomena in categorization, inference, background knowledge and learning.
