The operant conditioning chamber was created by B. F. Skinner while he was a graduate student at Harvard University. The chamber can be used to study both operant conditioning and classical conditioning. [1] [2] Skinner created the operant conditioning chamber as a variation of the puzzle box originally created by Edward Thorndike. [3]
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 .
An operant conditioning chamber (also known as a "Skinner box") is a laboratory apparatus used in the experimental analysis of animal behavior. It was invented by Skinner while he was a graduate student at Harvard University. As used by Skinner, the box had a lever (for rats), or a disk in one wall (for pigeons).
The experimental analysis of behavior is a science that studies the behavior of individuals across a variety of species. A key early scientist was B. F. Skinner who discovered operant behavior, reinforcers, secondary reinforcers, contingencies of reinforcement, stimulus control, shaping, intermittent schedules, discrimination, and generalization.
All these theories relate stimulus with response such that a person or animal learns and changes its behavior based upon the stimulus it receives. One significant theory proposed by B.F, Skinner is operant conditioning. [31] This theory claims that the consequences from behaviors will determine future behavior.
In rats, the fear-motivated response is to freeze, so in both fear extinction and avoidance conditioning inhibition of the amygdala via the mPFC leads to more movement (shuttling) and less freezing. The basolateral region of the amygdala is implicated in extinction of fear behaviors and expression of avoidance behaviors; [ 2 ] [ 3 ] however ...
The free operant has advantages in this respect, because it removes restrictions on the frequency with which a response can occur and permits the observation of moment-to-moment changes in frequency.

Psychological behaviorism is a form of behaviorism—a major theory within psychology which holds that generally human behaviors are learned—proposed by Arthur W. Staats. The theory is constructed to advance from basic animal learning principles to deal with all types of human behavior, including personality, culture, and human evolution.
