As feedback mechanisms also evolved to overcome the effect of molecules from eternal sources that interfere with receptors ( and thereby interfere with information processing ) through a variety of means, treatment with psychotropic drugs should produce ' withdrawal ' like symptoms with long or even short term use of an unchanged dose ( this is called dependence ), thus the chemical imbalance theory is under attack due to published evidence on how feedback mechanisms respond to drugs-rather than a lack of evidence on changes in neurotransmitters in patients with mental illness.

The purpose of the model is to demonstrate that feedback mechanisms can evolve from the actions or activities of self-interested organisms, rather than through classic group selection mechanisms.
Lovelock has suggested that global biological feedback mechanisms could evolve by natural selection, stating that organisms that improve their environment for their survival do better than those that damage their environment.
However, in 1981, W. Ford Doolittle, in the CoEvolution Quarterly article " Is Nature Motherly " argued that nothing in the genome of individual organisms could provide the feedback mechanisms proposed by Lovelock, and therefore the Gaia hypothesis proposed no plausible mechanism and was unscientific.

Test users can also provide feedback from a targeted audience: a software development team creating a customer relationship management software system for higher education can have a user with a similar profile explore the technology, offering opportunities to cater the further development of the system.
Although feedback is an important aspect of control engineering, control engineers may also work on the control of systems without feedback.
Internal factors not only control ecosystem processes but are also controlled by them and are often subject to feedback loops.
In addition to the feedback oscillators described above, which use two-port amplifying active elements such as transistors and op amps, linear oscillators can also be built using one-port ( two terminal ) devices with negative resistance, such as magnetron tubes, tunnel diodes and Gunn diodes.
Although a digital filter can be an IIR filter if the algorithm implementing it includes feedback, it is also possible to easily implement a filter whose impulse truly goes to zero after N time steps ; this is called a finite impulse response ( FIR ) filter.
Immersive virtual musical instruments, or immersive virtual instruments for music and sound aim to represent musical events and sound parameters in a virtual reality so that they can be perceived not only through auditory feedback but also visually in 3D and possibly through tactile as well as haptic feedback, allowing the development of novel interaction metaphors beyond manipulation such as prehension.
Madden-Julian activity can also produce eastward-propagating oceanic Kelvin waves, which may in turn be influenced by a developing El Niño, leading to a positive feedback loop.

Ruth Benedict made a distinction, relevant in this context, between " guilt " societies ( e. g., medieval Europe ) with an " internal reference standard ", and " shame " societies ( e. g., Japan, " bringing shame upon one's ancestors ") with an " external reference standard ", where people look to their peers for feedback on whether an action is " acceptable " or not ( also known as " group-think ").
The modern PC keyboard also includes a control processor and indicator lights to provide feedback to the user about what state the keyboard is in.
When it is present at a much higher concentration, it also binds to OR3, inhibiting transcription from P < sub > RM </ sub >, thus regulating its own levels in a negative feedback loop.
The term " computer game " also includes games which display only text ( and which can therefore theoretically be played on a teletypewriter ) or which use other methods, such as sound or vibration, as their primary feedback device, but there are very few new games in these categories.
However, it was also argued that muscular tension resulting from holding down buttons could be exploited in user interface design as it gives constant feedback that the user is in a temporary state, or mode ( Buxton, 1995 ).
