  2. Field theory (psychology) - Wikipedia

    en.wikipedia.org/wiki/Field_theory_(psychology)

    Field theory is important aspect of Gestalt theory, a doctrine that includes many important methods and discoveries. It is a crucial building block to the foundation of Gestalt psychologists' concepts and applications. The field theory is also a cornerstone of Gestalt therapy [7] together with phenomenology and existentialist dialog.

  3. Field theory (sociology) - Wikipedia

    en.wikipedia.org/wiki/Field_theory_(sociology)

    In sociology, field theory examines how individuals construct social fields, and how they are affected by such fields. Social fields are environments in which competition between individuals and between groups takes place, such as markets , academic disciplines , musical genres , etc. [ 1 ]

  4. Field theory - Wikipedia

    en.wikipedia.org/wiki/Field_theory

    Field theory (physics), a physical theory which employs fields in the physical sense, consisting of three types: Classical field theory, the theory and dynamics of classical fields; Quantum field theory, the theory of quantum mechanical fields; Statistical field theory, the theory of critical phase transitions; Grand unified theory

  5. Mean-field theory - Wikipedia

    en.wikipedia.org/wiki/Mean-field_theory

    In mean field theory, the mean field appearing in the single-site problem is a time-independent scalar or vector quantity. However, this isn't always the case: in a variant of mean field theory called dynamical mean field theory (DMFT), the mean field becomes a time-dependent quantity.

  6. Decision field theory - Wikipedia

    en.wikipedia.org/wiki/Decision_field_theory

    The name decision field theory was chosen to reflect the fact that the inspiration for this theory comes from an earlier approach – avoidance conflict model contained in Kurt Lewin's general psychological theory, which he called field theory. DFT is a member of a general class of sequential sampling models that are commonly used in a variety ...

    en.wikipedia.org/wiki/Glossary_of_field_theory

    Field theory is the branch of mathematics in which fields are studied. This is a glossary of some terms of the subject. This is a glossary of some terms of the subject. (See field theory (physics) for the unrelated field theories in physics.)

  8. Quantum field theory - Wikipedia

    en.wikipedia.org/wiki/Quantum_field_theory

    In theoretical physics, quantum field theory (QFT) is a theoretical framework that combines classical field theory, special relativity, and quantum mechanics. [1]: xi QFT is used in particle physics to construct physical models of subatomic particles and in condensed matter physics to construct models of quasiparticles.

  9. Unified field theory - Wikipedia

    en.wikipedia.org/wiki/Unified_field_theory

    In physics, a unified field theory (UFT) is a type of field theory that allows all fundamental forces and elementary particles to be written in terms of a single type of field. According to modern discoveries in physics, forces are not transmitted directly between interacting objects but instead are described and interpreted by intermediary ...
