Psy/310 - The Perspectives of Watson, Skinner, and Tolman



The Perspectives of Watson, Skinner, and Tolman

It is well known that psychology has changed tremendously since the early years of the discipline. Many theories that were accepted and respected decades ago are no longer used. However, some ideas represent the foundation and the roots of psychology, and the psychologists who introduced these ideas are still highly respected and admired. This paper intends to introduce and compare the theories of three of the greatest psychology thinkers who ever lived: John Watson, Edward Tolman and B.F. Skinner. The three psychologists were the main individuals to influence Behaviorism in the United States. Behaviorism is one of the most important schools of thought in psychology, and it derived from a philosophical point of view of psychology. It believes that individuals have behaviors, and behaviorists try to understand how and for what reason these behaviors are learned. The main premise of this school of thought is that psychology should focus on observable behavior of people and animals, not on unconscious events that are almost impossible to observe (Cherry, 2012). 

John Watson

John Broadus Watson was born in January 9th of 1978. He grew up in North Carolina and although he did not consider himself a good student, he went to college when he was 16 years old. At the age of 21he graduated with a master’s degree. After that he started studying psychology at the University of Chicago, under the guidance of John Dewey, an American philosopher, psychologist, and educational reformer whose ideas were influential in education and social reform. He did not necessarily agree with Dewey’s ideas and ended up being advised by functionalist psychologist James Angell and physiologist Henry Donaldson, who both influenced deeply what would become behaviorism. In 1903 he earned his Ph.D. and in 1908 he started teaching psychology at John Hopkins University. He introduced his behaviorist ideas in 1913, in a seminal lecture at Columbia University. Watson believed that psychology should focus on observable behavior, instead of aspects of the unconscious mind, which were almost impossible to study accurately (Cooper, 2009). 

Watson’s most famous experiment was the one with “Little Albert.” Albert was a little boy whose father worked in the laboratory, and whenever the boy would go to work with his father, he would play with the laboratory rats to stay occupied. According to Watson, Albert would stimulate the rat, which would make it play with him. Watson then began to play a loud and scary sound every time the boy and the rat would begin to play. After the noise was associated with the rat for seven times, Albert started presenting a new response, fear and crying, whenever he was introduced again to the rat. After that his response became generalized toward all “furry” things, like stuffed animals, dogs, and even bearded men (Hernandez, 2008).

B.F. Skinner

Burrhus Frederic Skinner was born on March 20th of 1904, in a small town in Pennsylvania. As a child, B.F. Skinner was active and outgoing, and enjoyed school. He received his BA degree in English from the Hamilton College in New York, and he had the intention of becoming a writer. After some time of unsuccessful writing, he came upon a book published by Bertrand Russell, a British philosopher. The book was called “An Outline of Philosophy,” and after reading it, Skinner decided to go study psychology at Harvard University. In 1931, he attained his Ph.D. in psychology, and after that he created a new school of thought called Radical Behaviorism (Hernandez, 2008).

B.F. Skinner’s theory believes that the environment has a huge impact on behaviors. He also believed that the more a behavior is rewarded, the chances of that behavior happening again become higher, at the same time that the lack of reward decreases the chances of the occurrence of the behavior. Skinner created what became known as operant conditioning. In other words, Skinner believed that the consequences that came from a behavior have a direct connection to the possibility that behavior would happen again. One of Skinner’s most famous experiments was the one called “Skinner Box.” A Skinner Box is a chamber containing a bar that an animal can manipulate in order to make food, or any other type of reinforcement, be dispensed. The box allowed Skinner, and other scientists to repeat the experiment after him, to study and identify the animal’s behavior and how rapidly they would open the box after realizing that they would be rewarded for such accomplishment. The Skinner Box is a perfect example of operant conditioning (Cherry, 2009). 

Edward Tolman

Edward Chase Tolman was born in April 14th of 1886, in West Newton, Massachusetts. He studied in the Newton Public Schools, and although his older brother and him were expected to take over the family business, both of them decided to seek academic careers. Both brothers enrolled in the Massachusetts Institute of Technology, where Edward Tolman went after a bachelor’s degree in electrochemistry. However, after reading the works of William James, the famous philosopher and psychologist, he changed the course of his career and decided to study philosophy. After taking summer courses in philosophy and psychology, he concluded that he was not smart enough for philosophy and decided that he likes psychology better. In 1915 he received a Ph.D. from Harvard (Hernandez, 2008). 

Although Tolman was also a behaviorist, he was not as radical as Skinner. He believed that learning could happen without reinforcement and rewards, and defended the idea that the behavior learned was not just an automatic response to a stimulus, but that individuals also act based on beliefs, attitudes, and different conditions and situations. One of Tolman’s most important contributions not only to behaviorism, but also to psychology in general, was his cognitive theory of learning. He believed that the process of learning involved both knowledge and cognitions about the environment, and the way the subject interacted with it. Some of his ideas contradicted those from Watson, and Tolman’s behaviorism was known as “purposive behaviorism.” One of the main aspects of his theory was focusing on concepts of knowledge, planning and purpose (Hernandez, 2008). 

Tolman conducted many experiments in order to study and understand the process of learning. One of his most famous experiments is the one involving rats in a maze, where he observed the importance and influence of reinforcement on the way the rats learned how to get out of complex mazes. This experiment led him to conclude his Latent Leaning Theory, which describes the process of learning without rewards. He compared that process to the way individuals drive through the same route every day, or learn where objects are. The learning only becomes conscious when someone needs to find an object or needs to find a building, for example. His studies and theories led him to create cognitive maps, which were methods to store knowledge in a structured way, allowing the individual’s mind to visualize information and make it easier to recognition (Hernandez, 2008). 
  
Conclusion

John B. Watson, B.F. Skinner and Edward Tolman were all behaviorists, even though their arguments may have differed at some point. All three of them believed that behavior was the reason behind people functioning and acting the way they did. Watson’s theory defended the connection between the environment and a response. His ideas are still commonly used by psychologists and therapists to this day. Skinner, on the other hand, believed that the behavior was a result of a consequence, or in other words, he believed that the consequence received ta the time the behavior occurred was a crucial factor in determining the reoccurrence of that behavior. Although Skinner’s theory is still used, it is more common to see that kind of practice among animal training, for example when owners give dogs some treats for behaving properly. Finally, according to Tolmas’ theory, learning could occur even if rewards not being presented and it could definitely occur without the knowledge if it being learned. One of Edward Tolmas’ most important contributions to psychology was the cognition maps, which are still used in modern psychology (Goodwin, 2008). Although psychology has changed and some concepts are not applied anymore, the ideas presented by Watson, Skinner, and Tolman are still current and applicable, even after many decades since they were presented.
