Chapter 5, `The neurobiology of categorization', provides a review of
what is known about the neural bases for categorization. A major
theme of the chapter is that categories characterized by different
kinds of structures may enlist different types of learning and memory
processes that in turn rely on different brain circuitry. For example, as
noted in Chapters 2, 3, and 4, human adults possess the ability to
rapidly learn rule-based categories in which the rule splitting the
categories is explicit, verbalizable, accessible to conscious awareness
(e.g. red things go into group A, green things go into group B), and
believed to be stored in a declarative form of memory that enables
recall of facts and events.
Human adults also learn categories that require an integration of
information that is not readily verbalizable, may be slowly acquired,
and may be stored in a nondeclarative procedural memory system.
Figure 5.1 provides an example of categories that can be learned
through an integration of information about the orientation and
