The recurrent and typical interactions between a biological system and its enviroment.
Structural coupling may imply two different types of relationships. F. CAPRA explains this in the following way: "Kicking a stone and kicking a dog are two different stories, as G. BATESON was fond of pointing out. The stone will react to the kick according to a linear chain of cause and effect. Its behavior can be calculated by applying the basic laws of Newtonian mechanics. The dog will respond with structural changes according to its own nature and (nonlinear) pattern of organization. The resulting behavior is generally unpredictable"(1997, p. 219)
This means that the dog may growl, bite, moan, crouch, or run.
This possibility of various alternative behaviors, present both in dog and man introduces the possibility of different chains of events in the ongoing interactions between both… in an ongoing process. Among human beings this opens the way for example to "conversation" in Pask's sense.
Accordingly, in the autopoiesis theory of the observer, the relation of the organism with its environment is seen as an endless sequence of experiences made by the organism, not in terms of stimuli from an objective external reality registered merely in a passive way, but as a kind of reactive internal reorganization within the limits of already existing structures. Whatever these may be in terms of brain histology and/or neuronal connections, it is clear that each individual constructs his/her own frames of references, from his/her birth on (be it the technique of bicycling, or the rules of a language).
As a result of this structural coupling, these internal frames of references are internally reorganized, but still as self reproducing structures.
Structural coupling is specially significant in conversation between observing systems.
In MATURANA and VARELA's terms (as quoted by S. BRIER – 1995, p.7): "In the coupling, the autopoietic conduct of an organism A becomes a source of deformation for an organism B, and the compensatory behavior of organism B, in turn, as a source of deformation for organism A, whose compensating behavior acts again as a source of deformation of B, and so on recursively until the coupling is interrupted".
Structural coupling is now incorporated in systemic familiar therapy. It could even possibly be applied to economic and social systems. Even binary stars systems are structurally coupled!
