  2. Lewin's equation - Wikipedia

    en.wikipedia.org/wiki/Lewin's_equation

    The formula states that behavior is a function of the person and their environment: [1] = (,) Where is behavior, is person, and is the environment. This equation was first presented in Lewin's book, Principles of Topological Psychology, published in 1936. [2]

  3. Stevens's power law - Wikipedia

    en.wikipedia.org/wiki/Stevens's_power_law

    The principal methods used by Stevens to measure the perceived intensity of a stimulus were magnitude estimation and magnitude production. In magnitude estimation with a standard, the experimenter presents a stimulus called a standard and assigns it a number called the modulus. For subsequent stimuli, subjects report numerically their perceived ...

  4. Measures of conditioned emotional response - Wikipedia

    en.wikipedia.org/wiki/Measures_of_conditioned...

    In experimental psychology the term conditioned emotional response refers to a phenomenon that is seen in classical conditioning after a conditioned stimulus (CS) has been paired with an emotion-producing unconditioned stimulus (US) such as electric shock. [1]

  5. Temporal motivation theory - Wikipedia

    en.wikipedia.org/wiki/Temporal_motivation_theory

    In psychology, temporal motivation theory (TMT) is an integrative motivational theory developed by Piers Steel and Cornelius J. König. The theory emphasizes time as a critical and motivational factor. The argument for a broad, integrative theory stems from the absence of a single theory that can address motivation in its entirety.

  6. Conditioned emotional response - Wikipedia

    en.wikipedia.org/wiki/Conditioned_emotional_response

    This experiment is critical in experimental psychology for it demonstrated that the interaction of classical and operant conditioning contingency could be powerful in altering behavior. This work sparked a number of experiments on this interaction, resulting in important experimental and theoretical contributions on autoshaping, negative ...

  7. Constant elasticity of substitution - Wikipedia

    en.wikipedia.org/wiki/Constant_elasticity_of...

    The CES production function is a neoclassical production function that displays constant elasticity of substitution. In other words, the production technology has a constant percentage change in factor (e.g. labour and capital) proportions due to a percentage change in marginal rate of technical substitution.

  8. Returns to scale - Wikipedia

    en.wikipedia.org/wiki/Returns_to_scale

    In the long run, all factors of production are variable and subject to change in response to a given increase in production scale. In other words, returns to scale analysis is a long-term theory because a company can only change the scale of production in the long run by changing factors of production, such as building new facilities, investing ...

  9. Value added - Wikipedia

    en.wikipedia.org/wiki/Value_added

    The factors of production provide "services" which raise the unit price of a product (X) relative to the cost per unit of intermediate goods used up in the production of X. In national accounts , such as the United Nations System of National Accounts (UNSNA) or the United States National Income and Product Accounts (NIPA), gross value added is ...
