  2. Transition state theory - Wikipedia

    en.wikipedia.org/wiki/Transition_state_theory

    This theory was developed simultaneously in 1935 by Henry Eyring, then at Princeton University, and by Meredith Gwynne Evans and Michael Polanyi of the University of Manchester. [3] [4] [5] TST is also referred to as "activated-complex theory", "absolute-rate theory", and "theory of absolute reaction rates". [6]

  3. Activated complex - Wikipedia

    en.wikipedia.org/wiki/Activated_complex

    Transition state theory explains the dynamics of reactions. The theory is based on the idea that there is an equilibrium between the activated complex and reactant molecules. The theory incorporates concepts from collision theory, which states that for a reaction to occur, reacting molecules must collide with a minimum energy and correct ...

  4. Transtheoretical model - Wikipedia

    en.wikipedia.org/wiki/Transtheoretical_model

    Stages of change, according to the transtheoretical model. The transtheoretical model of behavior change is an integrative theory of therapy that assesses an individual's readiness to act on a new healthier behavior, and provides strategies, or processes of change to guide the individual. [1]

  5. Eyring equation - Wikipedia

    en.wikipedia.org/wiki/Eyring_equation

    The equation follows from the transition state theory, also known as activated-complex theory. If one assumes a constant enthalpy of activation and constant entropy of activation, the Eyring equation is similar to the empirical Arrhenius equation , despite the Arrhenius equation being empirical and the Eyring equation based on statistical ...

  6. Transition state - Wikipedia

    en.wikipedia.org/wiki/Transition_state

    The concept of a transition state has been important in many theories of the rates at which chemical reactions occur. This started with the transition state theory (also referred to as the activated complex theory), which was first developed around 1935 by Eyring, Evans and Polanyi, and introduced basic concepts in chemical kinetics that are still used today.

  7. Behavior modification - Wikipedia

    en.wikipedia.org/wiki/Behavior_modification

    Behavior modification is a treatment approach that uses respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior is modified with (antecedent) stimulus control and consequences, including positive and negative reinforcement contingencies to increase desirable behavior, as well as positive and negative punishment, and extinction to reduce ...

  8. Mode deactivation therapy - Wikipedia

    en.wikipedia.org/wiki/Mode_Deactivation_Therapy

    Mode deactivation therapy (MDT) was developed by Jack A. Apsche who recognized shortcomings of cognitive theory and cognitive-behavioral therapies, especially for the treatment of populations with complex psychological problems.

  9. Virginia Satir - Wikipedia

    en.wikipedia.org/wiki/Virginia_Satir

    She is also known for creating the Virginia Satir Change Process Model, a psychological model developed through clinical studies. Change management and organizational "gurus" of the 1990s and 2000s embrace this model to define how change impacts organizations. [5] [6] [7] She died in 1988 in Menlo Park, California, of pancreatic cancer, aged 72 ...
