Distributed cognition
（重定向自DCog）
Distributed cognition is an approach to cognitive science research that deploys models of the extended mind (see, for example, the paper The Extended Mind) by taking as the fundamental unit of analysis "a collection of individuals and artefacts and their relations to each other in a particular work practice" (Rogers and Ellis, 1994 ). "DCog" is a specific approach to distributed cognition (distinct from other meanings) which takes a computational perspective towards goal-based activity systems. Dcog frameworks employed were originally developed in the mid-1980s by Edwin Hutchins, who continues to be the leading pioneer and whose research is based at the University of California at San Diego.
