Abstract
Adaptive control of thought–rational (ACT–R; J. R. Anderson & C. Lebiere, 1998) has evolved into a
theory that consists of multiple modules but also explains how these modules are integrated to produce
coherent cognition. The perceptual-motor modules, the goal module, and the declarative memory module
are presented as examples of specialized systems in ACT–R. These modules are associated with distinct
cortical regions. These modules place chunks in buffers where they can be detected by a production
system that responds to patterns of information in the buffers. At any point in time, a single production
rule is selected to respond to the current pattern. Subsymbolic processes serve to guide the selection of
rules to fire as well as the internal operations of some modules. Much of learning involves tuning of these
subsymbolic processes. A number of simple and complex empirical examples are described to illustrate
how these modules function singly and in concert.
