Context: The field of psychology consists of many specialist domains of activity, which lack shared foundations. This means that the field as a whole lacks conceptual coherence. Problem: The aim of the article is to show how second-order cybernetics can provide both foundations and a unifying conceptual framework for psychology. Method: The field of psychology is overviewed. There is then a demonstration of how cybernetics can provide both foundations and a unifying conceptual framework. This entails defining some key cybernetics concepts (...) and showing how they have already permeated the field, largely implicitly, and showing how, when made explicit, they can unify the field. Results: I show how concepts from second-order cybernetics can unify “process” and “person” approaches within psychology and can also unify individual psychology and social psychology, a unification that also builds conceptual bridges with sociology. Implications: The results are of value for bringing order to an otherwise inchoate field. They afford better communication between those working in the field, which is likely to give rise to new research questions and more effective ways of tackling them. Constructivist content: Central to the article is a reliance on concepts taken from the constructivist perspective of second-order cybernetics. (shrink)

Although it is conceded that distinct knowledge domains do presentparticular problems of coming to know, in thispaper it is argued that it is possible to construct a domain independent modelof the processes of coming to know, one inwhich observers share understandings and do soin agreed ways. The model in question is partof the conversation theory of Gordon Pask. CT, as a theory of theory construction andcommunication, has particular relevance forfoundational issues in science and scienceeducation. CT explicitly propounds a ``radicalconstructivist'' epistemology. (...) A briefaccount is given of the main tenets of RC andCT's place in that tradition and the traditionsof cybernetics. The paper presents a briefnon-technical account of the main concepts ofCT including elaborations by Laurillard andHarri-Augstein and Thomas. As part of CT, Pask also elaborated a methodology – knowledgeand task analysis – for analysing the structureof different knowledge domains; thismethodology is sketched in outline. (shrink)
