Situated

[edit] Situated agents
In artificial intelligence and cognitive science, the term situated refers to an agent which is embedded in an environment.

Situatedness -- "An agent is 'situated' if it can acquire information about the current situation through its sensors in interaction with the environment. . . .

Situated automata
The principal drawback of the classical view is that explicit reasoning about the effects of lowlevel actions is too expensive to generate real-time behavior ...

A system situated in, and part of, an environment, which senses that environment, and acts on it, over time, in pursuit of its own agenda, so as to affect what it senses in the future.

The iterative training procedure also arranges the network so that units representing centers close together in the input space are also situated close together on the topological map.

Autonomous Agent
Is a system/agent situated within and a-part of an environment that senses that environment and acts on it, and over time, in pursuit of its own agenda(s) and so as to effect what it senses in the future.

In any case, this kind of 'stimulus-response' or 'situated-action' model became quite popular in the early years of Psychology. Some researchers even maintained that it could explain all human behavior. However, there are problems with this.

For example, Coleridge's use of "The Sun came up upon the left" and "The Sun now rose upon the right" as the opening-lines of two closely-situated stanzas enabled him to indicate to the reader that the ship was circumnavigating the globe, ...

Saddle A type of surface that is neither a peak nor a valley but still has a 0 gradient. Saddle points are situated such that moving in one direction takes one uphill, while moving in another direction would be downhill.

Even an epidermis and a mesophyll may be lacking. Instead for their gaseous exchanges they use a homogenous aerenchyma (thin-walled cells separated by large gas-filled spaces). Their stomata are situated at the upper surface.
