- Skopos theory
- The idea that translating and interpreting should primarily take into account the function of both the source and target text
The functional approach has a great affinity with Skopos theory. The function of a translation is dependent on the knowledge, expectations, values and norms of the target readers, who are again influenced by the situation they are in and by the culture. These factors determine whether the function of the source text or passages in the source text can be preserved or have to be modified or even changed.

- Rational choice theory
- Rational choice theory, also known as choice theory or rational action theory, is a framework for understanding and often formally modeling social and economic behavior. It is the main theoretical paradigm in the currently-dominant school of microeconomics. Rationality ("wanting more rather than less of a good") is widely used as an assumption of the behavior of individuals in microeconomic models and analysis and appears in almost all economics textbook treatments of human decision-making. It is also central to some of modern political science and is used by some scholars in other disciplines such as sociology and philosophy. It is the same as instrumental rationality, which involves seeking the most cost-effective means to achieve a specific goal without reflecting on the worthiness of that goal. Gary Becker was an early proponent of applying rational actor models more widely. He won the 1992 Nobel Memorial Prize in Economic Sciences for his studies of discrimination, crime, and human capital
- The Theory of Multiple Intelligences
- (Eğitim) Multiple intelligences is educational theory put forth by psychologist Howard Gardner, which suggests that an array of different kinds of "intelligence" exists in human beings. Gardner suggests that each individual manifests varying levels of these different intelligences, and thus each person has a unique "cognitive profile." The theory was first laid out in Gardner's 1983 book, Frames of Mind: The Theory of Multiple Intelligences, and has been further refined in subsequent years
- agency theory

- attachment theory
- (Psikoloji, Ruhbilim) Attachment theory is a psychological theory that provides a descriptive and explanatory framework for discussion of affectionate relationships between human beings. Most of attachment theory as we know it today is derived from the work of John Bowlby and stresses the attitudes and behaviors of young children toward their adult caregivers. However, a wide variety of social behaviors, occurring at all ages, is subsumed under the term "attachment". These behaviors can include care-seeking by children or others, peer relationships of all ages, romantic and sexual attraction, and responses to the care needs of infants or sick or elderly adults. Attachment behaviors are accompanied by emotional experiences that motivate the behavior, as well as by cognitive and memory functions
- bundle theory
- (Felsefe) Theory advanced by David Hume to the effect that the mind is merely a bundle of perceptions without deeper unity or cohesion, related only by resemblance, succession, and causation. Hume's well-argued denial of a substantial or unified self precipitated a philosophical crisis from which Immanuel Kant sought to rescue Western philosophy
- choice theory

- circuit theory
- Circuit theory is the theory of accomplishing work by means of routing matter through a loop. The types of matter used are: a.) In electronic or electrical circuits: electrons (and charged ions, both positive and negative) b.) In pneumatic circuits: compressed gas (normally ordinary air) c.) In hydraulic circuits: pressurized, relatively incompressible fluid
- collision theory
- (Kimya) Collision theory is a theory, proposed by Max Trautz and William Lewis in 1916 that qualitatively explains how chemical reactions occur and why reaction rates differ for different reactions. It assumes that for a reaction to occur the reactant particles must collide, but only a certain fraction of the total collisions, the effective collisions, cause the transformation of reactant molecules into products. This is due to the fact that only a fraction of the molecules have sufficient energy and the right orientation at the moment of impact to break the existing bonds and form new bonds. The minimal amount of energy needed so that the molecule is transformed is called activation energy. Collision theory is closely related to chemical kinetics
- color theory
- In the arts of painting, graphic design, and photography, color theory is a body of practical guidance to color mixing and the visual impact of specific color combinations. Although color theory principles first appear in the writings of Alberti (c.1435) and the notebooks of Leonardo da Vinci (c.1490), a tradition of "colory theory" begins in the 18th century, initially within a partisan controversy around Isaac Newton's theory of color (Opticks, 1704) and the nature of so-called primary colors. From there it developed as an independent artistic tradition with only sporadic or superficial reference to colorimetry and vision science
- conspiracy theory
- A theory seeking to explain a disputed case or matter as a plot by a secret group or alliance rather than an individual or isolated act
- copernican theory

- critical theory
- (Felsefe) A philosophical approach to culture, and especially to literature, seen from a modified Marxist perspective
- dlvo theory
- The DLVO theory is named after Derjaguin, Landau, Verwey and Overbeek who developed it in the 1940s. The theory describes the force between charged surfaces interacting through a liquid medium. It combines the effects of the van der Waals attraction and the electrostatic repulsion due to the so called double layer of counterions
- just war theory
- Just war theory (or Bellum iustum) is a doctrine of military ethics of Roman philosophical and Catholic origin, studied by moral theologians, ethicists and international policy makers, which holds that a violent conflict ought to meet philosophical, religious or political criteria
- mean field theory
- A many-body system with interactions is generally very difficult to solve exactly, except for extremely simple cases (Gaussian field theory, 1D Ising model.) The great difficulty (e.g. when computing the partition function of the system) is the treatment of combinatorics generated by the interaction terms in the Hamiltonian when summing over all states. The goal of mean field theory (MFT, also known as self-consistent field theory) is to resolve these combinatorial problems
- multiple nuclei theory
- A theory of urban land use according to which cities develop many different cores of activity
- probability theory
- Probability theory is the branch of mathematics concerned with analysis of random phenomena. The central objects of probability theory are random variables, stochastic processes, and events: mathematical abstractions of non-deterministic events or measured quantities that may either be single occurrences or evolve over time in an apparently random fashion. Although an individual coin toss or the roll of a die is a random event, if repeated many times the sequence of random events will exhibit certain statistical patterns, which can be studied and predicted. Two representative mathematical results describing such patterns are the law of large numbers and the central limit theorem
- rational action theory
- Rational choice theory, also known as choice theory or rational action theory, is a framework for understanding and often formally modeling social and economic behavior. It is the main theoretical paradigm in the currently-dominant school of microeconomics.

- (Bilim, İlim) The goal of an organization is to minimize its dependence on other organizations for the supply of scare resources and to find ways of influencing them to make resources available
- sef-consistent field theory
- A many-body system with interactions is generally very difficult to solve exactly, except for extremely simple cases (Gaussian field theory, 1D Ising model.) The great difficulty (e.g. when computing the partition function of the system) is the treatment of combinatorics generated by the interaction terms in the Hamiltonian when summing over all states. The goal of mean field theory (MFT, also known as self-consistent field theory) is to resolve these combinatorial problems
- self-discrepancy theory
- Self-Discrepancy Theory states that people compare themselves to internalized standards called "self-guides". These different representations of the self can be contradictory and result in emotional discomfort. Self-discrepancy is the gap between two of these self-representations. Self-Discrepancy Theory states that people are motivated to reduce the gap in order to remove disparity in self-guides
- theory of mind
- in recent years, the phrase "theory of mind" has more commonly been used to refer to a specific cognitive capacity: the ability to attribute mental states—beliefs, intents, desires, pretending, knowledge, etc.—to oneself and others and to understand that others have beliefs, desires and intentions that are different from one's own
