Cybernetics is a transdisciplinary approach for exploring regulatory and purposive systems—their structures, constraints, and possibilities. The core concept of the discipline is circular causality or feedback—that is, where the outcomes of actions are taken as inputs for further action. Cybernetics is concerned with such processes however they are embodied, including in environmental, technological, biological, cognitive, and social systems, and in the context of practical activities such as designing, learning, managing, and conversation.

The American Society for Cybernetics (ASC) is an American non-profit scholastic organization for the advancement of cybernetics as a science, a discipline, a meta-discipline and the promotion of cybernetics as basis for an interdisciplinary discourse. The society does this by developing and applying cybernetics’ concepts which are presented and published via its conferences and peer-reviewed publications. As a meta-discipline, it creates bridges between disciplines, philosophies, sciences, and arts.

In developmental psychology and moral, political, and bioethical philosophy, autonomy is the capacity to make an informed, uncoerced decision. Autonomous organizations or institutions are independent or self-governing. Autonomy can also be defined from a human resources perspective, where it denotes a level of discretion granted to an employee in his or her work. In such cases, autonomy is known to generally increase job satisfaction. Self-actualized individuals are thought to operate autonomously of external expectations. In a medical context, respect for a patient's personal autonomy is considered one of many fundamental ethical principles in medicine.

The term autopoiesis refers to a system capable of reproducing and maintaining itself by creating its own parts and eventually further components. The original definition can be found in the 1972 publication Autopoiesis and Cognition: The Realization of the Living by Chilean biologists Humberto Maturana and Francisco Varela to define the self-maintaining chemistry of living cells. Since then the concept has been also applied to the fields of cognition, systems theory, architecture and sociology.

A cochlear implant (CI) is a surgically implanted neuroprosthetic device to provide a person with moderate to profound sensorineural hearing loss a modified sense of sound. CI bypasses the normal acoustic hearing process to replace it with electric signals which directly stimulate the auditory nerve. A person with a cochlear implant receiving intensive auditory training may learn to interpret those signals as sound and speech. However, one third of deaf children do not develop language if they are on a CI program alone and have no sign language input.

Mick Ashby's ethical regulator theorem builds upon the good regulator theorem, which is ambiguous because being good at regulating does not imply being good ethically. "The ethical regulator theorem claims that the following nine requisites are necessary and sufficient for a cybernetic regulator to be both effective and ethical:Purpose expressed as unambiguously prioritized goals. Truth about the past and present. Variety of possible actions. Predictability of the future effects of actions. Intelligence to choose the best actions. Influence on the regulated system. Ethics expressed as unambiguously prioritized rules. Integrity of all subsystems. Transparency of ethical behavior.

The Homeostat is one of the first devices capable of adapting itself to the environment; it exhibited behaviours such as habituation, reinforcement and learning through its ability to maintain homeostasis in a changing environment. It was built by William Ross Ashby in 1948 at Barnwood House Hospital. After a few technical hiccups with short-circuits causing burn-outs, the homeostat was finally completed on 16 March 1948. It was an adaptive ultrastable system, consisting of four interconnected Royal Air Force bomb control units with inputs, feedback, and magnetically driven, water-filled potentiometers. It illustrated his law of requisite variety — automatically adapting its configuration to stabilize the effects of any disturbances introduced into the system.

The Human Use of Human Beings is a book by Norbert Wiener, the founding thinker of cybernetics theory and an influential advocate of automation; it was first published in 1950 and revised in 1954. The text argues for the benefits of automation to society; it analyzes the meaning of productive communication and discusses ways for humans and machines to cooperate, with the potential to amplify human power and release people from the repetitive drudgery of manual labor, in favor of more creative pursuits in knowledge work and the arts. The risk that such changes might harm society is explored, and suggestions are offered on how to avoid such risk.

Network science is an academic field which studies complex networks such as telecommunication networks, computer networks, biological networks, cognitive and semantic networks, and social networks, considering distinct elements or actors represented by nodes and the connections between the elements or actors as links. The field draws on theories and methods including graph theory from mathematics, statistical mechanics from physics, data mining and information visualization from computer science, inferential modeling from statistics, and social structure from sociology. The United States National Research Council defines network science as "the study of network representations of physical, biological, and social phenomena leading to predictive models of these phenomena."

An open system is a system that has external interactions. Such interactions can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept. An open system is contrasted with the concept of an isolated system which exchanges neither energy, matter, nor information with its environment. An open system is also known as a flow system.

Positive feedback is a process that occurs in a feedback loop which exacerbates the effects of a small disturbance. That is, the effects of a perturbation on a system include an increase in the magnitude of the perturbation. That is, A produces more of B which in turn produces more of A. In contrast, a system in which the results of a change act to reduce or counteract it has negative feedback. Both concepts play an important role in science and engineering, including biology, chemistry, and cybernetics.

Project Cybersyn was a Chilean project from 1971 to 1973 during the presidency of Salvador Allende aimed at constructing a distributed decision support system to aid in the management of the national economy. The project consisted of four modules: an economic simulator, custom software to check factory performance, an operations room, and a national network of telex machines that were linked to one mainframe computer.

Self-organization, also called spontaneous order, is a process where some form of overall order arises from local interactions between parts of an initially disordered system. The process can be spontaneous when sufficient energy is available, not needing control by any external agent. It is often triggered by seemingly random fluctuations, amplified by positive feedback. The resulting organization is wholly decentralized, distributed over all the components of the system. As such, the organization is typically robust and able to survive or self-repair substantial perturbation. Chaos theory discusses self-organization in terms of islands of predictability in a sea of chaotic unpredictability.

In cybernetics and control theory, a setpoint is the desired or target value for an essential variable, or process value of a system. Departure of such a variable from its setpoint is one basis for error-controlled regulation using negative feedback for automatic control. The set point is usually abbreviated to SP, and the process value is usually abbreviated to PV.
