That cognition is situated implies that it is context-dependent. The claim that cognition is context-dependent is not controversial per se. Context can influence thought processes in a number of ways, accidentally or systemati- cally, without in any way being essential to or constitutive of these processes. However, TSC champions a strong notion of context-dependence, to the effect that individual cognitive processes and states of the mind involve entities in the agent’s surroundings essentially and actively (Clancey 1991). External entities that are recruited by the agent during on-going action will have a direct casual impact on the agent’s behaviour, and play.
