In an historical account of the growth and development of the field of cognitive anthropology, Roy D'Andrade examines how cultural knowledge is organised within and between human minds. He begins by examining the research carried out during the l950s and l960s which was concerned with how different cultures classify kinship relationships and the natural environment, and then traces the development of more complex and sophisticated cognitive theories of classification in anthropology which took place in the l970s and l980s. In an analysis of more recent developments, the author considers work involving cultural models, emotion, motivation and action. He concludes with a summary of the theoretical perspective of cognitive anthropology.
