Operant conditioning, also called instrumental conditioning, is a learning process where voluntary behaviors are modified by association with the addition (or removal) of reward or aversive stimuli. The frequency or duration of the behavior may increase through reinforcement or decrease through punishment or extinction .
Contingency management (CM) is the application of the three-term contingency (or operant conditioning), which uses stimulus control and consequences to change behavior. CM originally derived from the science of applied behavior analysis (ABA), but it is sometimes implemented from a cognitive-behavioral therapy (CBT) framework as well.
The conditioned emotional response is usually measured through its effect in suppressing an ongoing response. For example, a rat first learns to press a lever through operant conditioning. Classical conditioning follows: in a series of trials the rat is exposed to a CS, often a light or a noise. Each CS is followed by the US, an electric shock.
Behavior modification was a treatment approach that used respondent and operant conditioning to change behavior. Based on methodological behaviorism, [1] overt behavior was 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 ...
The controlling effects of stimuli are seen in quite diverse situations and in many aspects of behavior. For example, a stimulus presented at one time may control responses emitted immediately or at a later time; two stimuli may control the same behavior; a single stimulus may trigger behavior A at one time and behavior B at another; a stimulus may control behavior only in the presence of ...
Central to operant conditioning is the use of a Three-Term Contingency (Discriminative Stimulus, Response, Reinforcing Stimulus) to describe functional relationships in the control of behavior. Discriminative stimulus (S D) is a cue or stimulus context that sets the occasion for a response. For example, food on a plate sets the occasion for eating.

Note that the suppression of lever-pressing was robust, even though the operant, lever-press - food contingency was not altered at all. 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.
