Little Albert ExperimentWho were the experimenters?The experimenters were John B. Watson and his student and wife Rosalie Rayner. John B Warner first studied at Furman University and then, with the help of his professor, Gordon Moore, moved to the University of Chicago. He became interested in the field of comparative psychology and the study of animals. In 1903, he received his doctorate and later became an associate professor of psychology at Johns Hopkins University. In 1913, he proposed the idea of ​​“behaviorism”. Behaviorism explains the ability to predict and control people's actions (Watson, 1999). Rosalie Rayner graduated from Vassar College in 1919 and enrolled at Johns Hopkins University for graduate study. At Johns Hopkins, she became an assistant to John B. Watson and embarked on the now infamous "Little Albert" experiments which resulted in an affair between Watson and Rayner. As a result of this, Watson was forced to leave the university, Rayner also left without completing her degree. They later moved to Connecticut and had two children whom they raised according to behaviorist principles (Smirle, 2013). What was the hypothesis? The hypothesis was that little Albert could learn to fear certain things, he would acquire a fear reaction to a white message. rat by classical conditioning after the white rat was associated with a loud noise. Who were the participants? The participant was a little boy who they decided to name “little Albert” or “Albert B”. However, recent discoveries have uncovered the boy's true identity, who they believe was named Douglas Merritte. There was a period of preconditioning, almost from birth until nine months of age, when the real testing began. The last recorded observation...... middle of paper ...... which means it could be biased. There is also no informed consent on any database. The study caused serious distress to the child. It is also known that the child known to be Little Albert, Douglas Merritt, was diagnosed with hydrocephalus and it is believed that Watson knew about this. Whether Warner knew it or not, Albert's temperament and behavior were not normal for his age. The delay and autism spectrum disorder could be the reason why Albert reacted this way during the experiment. However, there is a different theory that his disorder was caused after the study due to the freezing temperatures and bright lights, but this is very unlikely (Fridlund, Hall, Williams, 2011). What were the contributions to the science of psychology?Classical conditioning was proven and behaviorism was now a proven theory.
