computational metaphor (of cognition)
Hutchins (1995a, 117) defines a “computation” as referring to “the propagation of representational state across representational media.” The computational metaphor is the position taken that cognition is a form of computation, and that mental state is encoded analogously to computer representations. The term “metaphor.” Within cognitive science, the computational metaphor is also known as the “representational theory of mind,” in which computations are actions on representations. DCog claims that the computational metaphor can be applied to a unit of analysis broader than an individual’s mind (i.e., the functional system).
computer-supported cooperative work (CSCW)
The design of systems to support interaction and cooperative working. It emerged in the late 1980s as a result of dissatisfactions with the predominantly cognitivist paradigm employed in human-computer interaction (HCI) and in recognition of the importance of questions regarding organizations, work, and interaction for the design of computer systems.
A structure describing the concepts in a cognitive system, less specific than a cognitive architecture.
In the context of cognitive work analysis, factors that limit, but do not prescribe, how effective work activity might be carried out.
control task analysis
A way of analyzing work that focuses on the control that must be exercised over a work domain and the tasks implied to exercise such control. An analytic phase of cognitive work analysis.
controlled cognitive processes
Processes that require monitoring and effort or attention during their execution. See also automatic cognitive processes.
Originated by Harvey Sacks, this is often coupled with ethnomethodology and is the study of the way in which conversationalists order and accomplish their exchange of speech with each other as a situated and locally organized matter.
software agents that are interact with the user using natural language and that are often given a human-like appearance
cost structure of information
An analysis of the resource and opportunity costs involved in accessing and handling information from a physical or virtual information system.
