A box used in operant conditioning of animals, which limits the available responses and thus increases the likelihood that the desired response will occur, is called a ________ box.

A) Skinner
B) Watson
C) trial
D) response

A Skinner box, also known as an operant conditioning chamber, was created by B.F. Skinner to study animal behavior through operant conditioning. The box limits the animal's available responses, typically through levers or buttons, and reinforces the desired behavior with rewards such as food or water. This increases the likelihood of the desired behavior occurring in the future. Watson and trial are not terms used to describe a operant conditioning box, and response is too broad of a term without the specific context of operant conditioning.
