In his earlier years Watson used animal subjects to study behavior. Later he turned to the study of human behaviors and emotions. Until World War I he collaborated his studies with Adolph Meyer. After the war he resumed his work at Johns Hopkins University. He wanted to develop techniques to allow him to " condition and control them emotions of human subjects.' " His famous study for this was called the Little Albert Experiment in which he theorized that children have three basic emotional reactions: fear, rage, and love.
He wanted to prove that these three reactions could be artificially conditioned in children. Watson used a little boy named Albert to test his theory. He repeatedly presented Albert a rat in conjunction with a sudden, loud noise to classically condition fear of the rat. This is human being abuse, child abuse, a satanic ritual at the professional level, and could be lightly considered to be a capital crime against humanity!
