Distributed cognition is a school of psychology developed in the 1990s by Edwin Hutchins. Using insights from sociology and the psychology of Vygotsky (cf activity theory) it emphasises the social aspects of cognition.

Distributed cognition views a system as a set of representations, and models the interchange of information between these representations. These representations can be either in the mental space of the participants or external representations available in the environment.
