Warren Sturgis McCulloch was an American neurophysiologist and cybernetician, known for his work on the foundation for certain brain theories and his contribution to the cybernetics movement. Along with Walter Pitts, McCulloch created computational models based on mathematical algorithms called threshold logic which split the inquiry into two distinct approaches, one approach focused on biological processes in the brain and the other focused on the application of neural networks to artificial intelligence.
Heinz von Foerster was an Austrian-American scientist combining physics and philosophy, and widely attributed as the originator of second-order cybernetics. He was twice a Guggenheim fellow and also was a fellow of the American Association for the Advancement of Science, 1980. He is well known for his 1960 Doomsday equation formula published in Science predicting future population growth.
Social constructionism is a term used in sociology, social ontology, and communication theory. The term can serve somewhat different functions in each field; however, the foundation of this theoretical framework suggests various facets of social reality—such as concepts, beliefs, norms, and values—are formed through continuous interactions and negotiations among society's members, rather than empirical observation of physical reality. The theory of social constructionism posits that much of what individuals perceive as 'reality' is actually the outcome of a dynamic process of construction influenced by social conventions and structures.
Constructivism is a view in the philosophy of science that maintains that scientific knowledge is constructed by the scientific community, which seeks to measure and construct models of the natural world. According to constructivists, natural science consists of mental constructs that aim to explain sensory experiences and measurements, and that there is no single valid methodology in science but rather a diversity of useful methods. They also hold that the world is independent of human minds, but knowledge of the world is always a human and social construction. Constructivism opposes the philosophy of objectivism, embracing the belief that human beings can come to know the truth about the natural world not mediated by scientific approximations with different degrees of validity and accuracy.
Sociocybernetics is an interdisciplinary science between sociology and general systems theory and cybernetics. The International Sociological Association has a specialist research committee in the area – RC51 – which publishes the (electronic) Journal of Sociocybernetics.
Constructivism is a theory in education which posits that individuals or learners do not acquire knowledge and understanding by passively perceiving it within a direct process of knowledge transmission, rather they construct new understandings and knowledge through experience and social discourse, integrating new information with what they already know. For children, this includes knowledge gained prior to entering school. It is associated with various philosophical positions, particularly in epistemology as well as ontology, politics, and ethics. The origin of the theory is also linked to Swiss developmental psychologist Jean Piaget's theory of cognitive development.
Radical constructivism is an approach to epistemology that situates knowledge in terms of knowers' experience. It looks to break with the conception of knowledge as a correspondence between a knower's understanding of their experience and the world beyond that experience. Adopting a skeptical position towards correspondence as in principle impossible to verify because one cannot access the world beyond one's experience in order to test the relation, radical constructivists look to redefine epistemology in terms of the viability of knowledge within knowers' experience. This break from the traditional framing of epistemology differentiates it from "trivial" forms of constructivism that emphasise the role of the knower in constructing knowledge while maintaining the traditional perspective of knowledge in terms of correspondence. Radical constructivism has been described as a "post-epistemological" position.
Second-order cybernetics, also known as the cybernetics of cybernetics, is the recursive application of cybernetics to itself and the reflexive practice of cybernetics according to such a critique. It is cybernetics where "the role of the observer is appreciated and acknowledged rather than disguised, as had become traditional in western science". Second-order cybernetics was developed between the late 1960s and mid 1970s by Heinz von Foerster and others, with key inspiration coming from Margaret Mead. Foerster referred to it as "the control of control and the communication of communication" and differentiated first order cybernetics as "the cybernetics of observed systems" and second-order cybernetics as "the cybernetics of observing systems".
Ranulph Glanville was an Anglo-Irish cybernetician and design theorist. He was a founding vice-president of the International Academy for Systems and Cybernetic Sciences (2006–2009) and president of the American Society for Cybernetics (2009–2014).
Humberto Maturana Romesín was a Chilean biologist and philosopher. Many consider him a member of a group of second-order cybernetics theoreticians such as Heinz von Foerster, Gordon Pask, Herbert Brün and Ernst von Glasersfeld, but in fact he was a biologist, scientist.
In psychology, constructivism refers to many schools of thought that, though extraordinarily different in their techniques, are all connected by a common critique of previous standard approaches, and by shared assumptions about the active constructive nature of human knowledge. In particular, the critique is aimed at the "associationist" postulate of empiricism, "by which the mind is conceived as a passive system that gathers its contents from its environment and, through the act of knowing, produces a copy of the order of reality".
Stuart Anspach Umpleby is an American cybernetician and professor in the Department of Management and Director of the Research Program in Social and Organizational Learning in the School of Business at the George Washington University.
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. The ASC is a full member of the International Federation for Systems Research (IFSR).
Constructivist Foundations is an international triannual peer-reviewed academic journal that focuses on constructivist approaches to science and philosophy, including radical constructivism, enactive cognitive science, second-order cybernetics, biology of cognition and the theory of autopoietic systems, and non-dualizing philosophy. It was established in 2005 and the editor-in-chief is Alexander Riegler.
Cybernetics is a field of systems theory that studies circular causal systems whose outputs are also inputs, such as feedback systems. It is concerned with the general principles of circular causal processes, including in ecological, technological, biological, cognitive and social systems and also in the context of practical activities such as designing, learning, and managing.
The Biological Computer Laboratory (BCL) was a research institute of the Department of Electrical Engineering at the University of Illinois Urbana-Champaign. It was founded on 1 January 1958, by then Professor of Electrical Engineering Heinz von Foerster. He was head of BCL until his retirement in 1975.
Bernhard Pörksen is a German media scholar.
Autonomous agency theory (AAT) is a viable system theory (VST) which models autonomous social complex adaptive systems. It can be used to model the relationship between an agency and its environment(s), and these may include other interactive agencies. The nature of that interaction is determined by both the agency's external and internal attributes and constraints. Internal attributes may include immanent dynamic "self" processes that drive agency change.
Relational constructivism can be perceived as a relational consequence of radical constructivism. In contrary to social constructivism, it picks up the epistemological threads and maintains the radical constructivist idea that humans cannot overcome their limited conditions of reception. Therefore, humans are not able to come to objective conclusions about the world.
Josef Mitterer is an Austrian philosopher, and a retired professor at the University of Klagenfurt Department of Philosophy.
