Distributed cognition

Distributed cognition is an approach to cognitive science research that was developed by cognitive anthropologist Edwin Hutchins during the 1990s. From cognitive ethnography, Hutchins argues that mental representations, which classical cognitive science held that are within the individual brain, are actually distributed in sociocultural systems that constitute the tools to think and perceive the world. Thus, a native of the Carolina Islands can perceive the sky and organize his perceptions of the constellations typical of his culture (the groupings of stars are different than in the traditional constellations of the West) and use the position of the stars in the sky as a map to orient himself in space while sailing overnight in a canoe. According to Hutchins, cognition involves not only the brain but also external artifacts, work teams made up of several people, and cultural systems for interpreting reality (mythical, scientific, or otherwise). Distributed cognition theory is part of the interdisciplinary field of embodied cognitive science, also called embodied cognition. Hutchins' distributed cognition theory influenced philosopher Andy Clark, who shortly after proposed his own version of the theory, calling it "extended cognition" (see, for example, the paper The Extended Mind). Hutchins' distributed cognition theory explains mental processes by taking as the fundamental unit of analysis "a collection of individuals and artifacts and their relations to each other in a particular work practice". "DCog" is a specific approach to distributed cognition (distinct from other meanings) which takes a computational perspective towards goal-based activity systems. The distributed cognition approach uses insights from cultural anthropology, sociology, embodied cognitive science, and the psychology of Lev Vygotsky (cf. cultural-historical psychology). It emphasizes the ways that cognition is off-loaded into the environment through social and technological means. It is a framework for studying cognition rather than a type of cognition.
