How is negative feedback characterized in systems theory?

In systems theory, negative feedback is characterized as feedback that maintains homeostasis. Homeostasis refers to the ability of a system to regulate its internal environment and maintain stable, constant conditions in response to external changes. Negative feedback mechanisms serve to correct deviations from an ideal or set point.

For example, if a system deviates from a desired state, negative feedback acts to counteract that deviation, pushing the system back towards equilibrium. This is seen in various biological and psychological systems; when a temperature rises in the body, mechanisms are triggered to lower it back to the set point. In the context of families and relationships, negative feedback can help to stabilize interactions and maintain balance, promoting a healthy dynamic instead of allowing chaos or extreme variations.

Other options present interpretations that do not align with the primary role of negative feedback in systems theory. Disruption of homeostasis aligns more with positive feedback, which amplifies changes rather than restoring equilibrium. Similarly, supportive mechanisms for growth are typically associated with positive feedback or other supportive processes, not negative feedback specifically. Lastly, while negative feedback does promote stability, it is not primarily about promoting change; that role is more accurately attributed to positive feedback systems. Thus, understanding negative feedback as a mechanism that helps maintain homeostasis is
