Cognitive archaeology is a truly interdisciplinary field that applies the theories and methods of several academic domains (cognitive psychology, neuropsychology, archaeology, linguistics, philosophy of mind, philosophy of consciousness, etc.) to the tangible evidence for human evolution—non-human primate anatomy and behavior, human neuroanatomy, hominin paleontology, and archaeology. It studies the origins and adaptive purposes of such cognitive processes and capabilities as concept formation, spatial cognition, social cognition, language, symbolic structures, and working memory.
