Definitionv1DF-310
Cognitive extension
the functional integration of external resources into cognitive processes such that the external resource plays the same functional role in guiding behavior as an internal cognitive process, thereby constituting a genuine part of the cognitive system
Why This Is a Definition
This definition clearly establishes the precise semantic boundary of 'cognitive extension' by identifying its genus (functional integration of external resources into cognitive processes) and differentia (playing the same functional role in guiding behavior as internal cognitive processes). It distinguishes it from mere tools or artifacts by requiring functional equivalence rather than just occasional consultation. The definition is consistent with the extended mind thesis presented in the lesson and specifically references the criteria from Clark and Chalmers' work.
