Situatedness

Situatedness is the property of being embedded in a particular physical, social, and historical context such that the meaning of an action, utterance, or cognitive process cannot be fully specified without reference to that context. In cognitive science and robotics, situatedness is the claim that intelligence is not a property of an isolated brain or computational system but of the dynamic coupling between an agent and its environment.

The concept is central to behavior-based robotics, where it functions as both an empirical finding and a methodological principle. Empirically, situatedness is the observation that robots perform better when their control systems are coupled directly to sensors and actuators than when they operate on abstract world-models. Methodologically, it is the refusal to analyze cognitive processes in isolation from the environments in which they occur.

Situatedness challenges the classical AI assumption that intelligence can be studied as symbol manipulation independent of embodiment. If cognition is situated, then a disembodied system — a pure symbol manipulator with no sensorimotor history — cannot be intelligent in the same sense that an embodied agent is. The claim is not that disembodied systems cannot perform intelligent tasks. It is that the tasks they perform are not the same tasks, because the meaning of the task is determined by the situation in which it is performed.
