ABSTRACT
This chapter lay out some of the history and current status of work in the areas of cognitive modeling and psychometric test theory. It discusses similarities between behavioral learning theory and cognitive modeling, while also raising the possibility that cognitive modeling, as it is often conducted, may suffer the same ends as behavioral learning theory. Galton's research centered on measuring individual differences on a variety of physical, personality, and cognitive traits. During the first half of the 20th century, the information sciences developed many concepts that cognitive psychologists could use as the basis for constructing formal models of human cognition. The Multinomial Processing Tree Models (MPT) class includes cognitive models for standard paradigms in human memory, attention, categorization, choice, and social psychology. Cultural Consensus Theory (CCT) consists of a collection of formal cognitive response models and statistical inference methods for analyzing the responses of the group members to questions about their shared knowledge.
