Before we discuss animal psychology, we need to make sense of behaviorism and behaviorist psychology. The emergence of behaviorism took American psychology by storm in the 1910s, 1920s, and 1930s. In 1913 Watson as the founder of behaviorism addressed the failure of introspective method as a flaw of psychology, specifically he argued that "the behavior of animals and man can be investigated without appeal to consciousness and must be viewed as being equally essential to a general understanding of behavior" (Pickren & Rutherford, 2010, p. 61). Watson used this argument to set forth a revised conceptualization of psychology, which came to be known as behaviorism. He argued that psychology “as the behaviorist views it”’ is a “purely objective experimental branch of natural science. Its theoretical goal is the prediction and control of behavior.
