The operant chamber was created by B.F. Skinner to assist with laboratory analysis of animal behavior. The chamber is a box that holds the test subject, an animal such as a rat, and is often sound and light proof, to limit responses from unintended stimuli. The box is built with a system for delivering a stimulus and can detect the response. It has an automatic system of reward or punishment delivery, simplifying the process of observation and data collection in behavioral studies.
