Feedback/psychology/Carver/Scheier: Approaching a goal illustrates the principle of feedback control. A feedback loop involves four sub-functions (Miller, Galanter and Pribram 1960(1); MacKay1966(2); Powers1973(3); Wiener1948(4)): an input, a reference value, a comparison, and an output.
A reference value is a goal. The input is compared to the reference value. Any discrepancy detected is called an ‘error signal’. We treat the output here as behaviour, but sometimes the behaviour is internal.
If the comparison detects no discrepancy, the output remains as it was. How detection of a discrepancy affects output depends on what kind of loop it is. In a discrepancy reducing loop, the output acts to reduce the discrepancy. Such an effect is seen in attempts to reach a valued goal, maintain a desired condition, or conform to a standard.
There also are discrepancy-enlarging loops, which avoid the reference value rather than approach it. The value in this case is a threat or an ‘anti-goal’, for example, a feared or disliked possible self (Carver, Lawrence and Scheier 1999(5); Ogilvie 1987(6)). >Affect/Carver/Scheier.

Some feedback processes have no explicit representation of a reference value. The system regulates around a value, but no value is represented as a goal (Berridge 2004(7); Carver and Scheier2002)(8).
