Cognitive anthropology is an approach within cultural anthropology in which scholars seek to explain patterns of shared knowledge, cultural innovation, and transmission over time and space using the methods and theories of the cognitive sciences (especially experimental psychology and evolutionary biology) often through close collaboration with historians, ethnographers, archaeologists, linguists, musicologists and other specialists engaged in the description and interpretation of cultural forms. Cognitive anthropology is concerned with what people from different groups know and how that implicit knowledge, in the sense of what they think subconsciously, changes the way people perceive and relate to the world around them.
Cognitive anthropology studies a range of domains including folk taxonomies, the interaction of language and thought, and cultural models.
From a linguistics stand-point, cognitive anthropology uses language as the doorway to study cognition. Its general goal is to break language down to find commonalities in different cultures and the ways people perceive the world. Linguistic study of cognitive anthropology may be broken down into three subfields: semantics, syntactics, and pragmatics.
In contrast to traditional ethnographic methods in cultural anthropology, cognitive anthropology primarily uses quantitative methodologies in order to study culture. Because of the field's interest in determining shared knowledge, consensus analysis has been used as its most widely used statistical measure.
One of the techniques used is Cultural Network Analysis, the drawing of networks of interrelated ideas that are widely shared among members of a population. Recently there has been some interchange between cognitive anthropologists and those working in artificial intelligence.
