Models of Human Cognition
Human as “information processing system” Predict performance, not describe truth
Other models? Distributed cognition Activity theory Situated action

Situated Action
Emergent property of moment-by-moment interactions
Relation between persons and arenasImprovisationDetailed temporal accountsDe-emphasizes rigid plans and
rational problem solving

Activity Theory
Subject, object, actions and operations
Flexible in face of changing conditions
Mediation by artifactsTransformative relationship

Distributed Cognition
Distributed collection of interacting people and artifacts
Less emphasis on individual cognition; system goal
Representations and transformationsCollaboration
