B.F. Skinner's Shaping Experiment (Skinner's Box) An adherent to Watson's theory of behaviorism, B.F. Skinner was able to demonstrate how one can modify behavior through a process he called "shaping." In contrast to pure classical conditioning, Skinner utilized positive and negative reinforcement to cause behavior. Utilizing a contraption that became known as "Skinner's Box" he demonstrated how he could shape the behavior of pigeons by reinforcing their behavior.
