Couplings: links allowing for the flow of information from one component to the next. Positive coupling: a change in one component is a stimulus that leads to a change of the. Negative coupling: a change in one component stimulates a change of the opposite same direction in the linked component. direction in the linked component. Feedback loop ( round trip ): a self-perpetuating mechanism of change and a response to that change. Negative feedback loop: diminish the effects of disturbances. Positive feedback loops: amplify the effects of disturbances. Equilibrium state: it will not change unless the system is disturbed.
