An operant conditioning chamber (also known as a Skinner box) is a laboratory apparatus used to study animal behavior. 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]
Mouse Operant Conditioning Chamber with Food Dispenser. Experiments are done in a mouse operant conditioning chamber. [1] Conditioning chambers are used to train animals to do simple tasks such as pulling a lever or pushing a button. The animals can be rewarded or punished for doing these tasks.
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 .
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.
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).
This screen was mounted on pivots and fitted with sensors that measured any angular movement. One to three pigeons, trained by operant conditioning to recognize the target, were stationed in front of the screen; when they saw the target, they would peck at the screen with their beaks. They were trained by being shown an image of the target and ...
In the laboratory, this is usually represented by a rat given a small shock to its feet through a grid floor and shuttling through a small opening in its chamber which stops the shock. Such a response is considered active avoidance when it occurs prior to the stimulus presentation and prevents the stimulus from occurring.
Operant conditioning represents the behavioral paradigm underlying self-administration studies. Although not always required, subjects may be first pre-trained to perform some action, such as a lever press or nose poke to receive a food or water reward (under food- or water- restricted conditions, respectively).
