family psychotherapy: feedback
loop/feedback/evolutionary feedback
"Feedback is a method of controlling a system by
reinserting into it the results of its past performance" (Wiener, 1954/1967, p. 84). Feedback
loops and feedback structures are essential elements in cybernetic systems. In traditional family theory, negative
(deviation-counteracting) feedback was conceptualized as regulating families and
other systems (homeostasis),
as a precondition for the survival of the system in a constantly changing environment.
This formulation was more satisfactory for explaining stability and
morphostasis than in understanding change,
especially discontinuous change. The concepts of positive (deviation-amplifying) feedback
and evolutionary feedback, as well as morphogenesis,
coherence,
and coevolution,
have been advanced to correct "simple" feedback theories.*
