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]
Water deprivation is 18 hours or water is provided for 1 hour a day for four days before beginning the test. Electrical shock is only given for a 3-5 minute time period. [3] The VCT can be done with food deprivation too. Before beginning the test animals must be acclimated to the cage and food pellets. The conditioning chamber must be checked ...
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).
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 .
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).
A classical experiment in operant conditioning, for example, is the Skinner Box, "puzzle box" or operant conditioning chamber to test the effects of operant conditioning principles on rats, cats and other species. From this experiment, he discovered that the rats learned very effectively if they were rewarded frequently with food.
