Modularity and decision making
Robert Kurzban University of Pennsylvania & Chapman University
Mechanisms that are useful are often specialized because of the efficiency gains that derive from specialization. This principle is in evidence in the domain of tools, artificial computational devices, and across the natural biological world. Some have argued that human decision making is similarly the result of a substantial number of functionally specialized, or “modular” systems, brought to bear on particular decision making tasks. Which system is recruited for a given decision making task depends on the cues available to the decision maker. A number of research programs have advanced using these ideas, but the approach remains controversial.
