The Little Albert Experiment

One of the most famous figures in psychology history isn't a psychologist at all. "Little Albert," as he was called, was the pseudonym of a young boy at the center of the infamous psychology experiment in which he was conditioned to fear rats—a fear that also extended to other similar objects, including fluffy white toys and a white beard.

The Little Albert experiment was a famous psychology experiment conducted by behaviorist John B. Watson and graduate student Rosalie Rayner. Previously, Russian physiologist Ivan Pavlov had conducted experiments demonstrating the conditioning process in dogs. Watson took Pavlov's research a step further by showing that emotional reactions could be classically conditioned in people.

Keep reading to learn more about what happened in the Little Albert experiment, what it reveals about the conditioning process, and why it is considered so controversial.

What Happened in the Little Albert Experiment?

The experiment's participant was a child that Watson and Rayner called "Albert B." but is known popularly today as Little Albert. When Little Albert was 9 months old, Watson and Rayner exposed him to a series of stimuli, including a white rat, a rabbit, a monkey, masks, and burning newspapers, and observed the boy's reactions.

At the experiment's outset, the little boy showed no fear of any objects he was shown. What Watson did next changed everything. The next time Albert was exposed to the rat, Watson made a loud noise by hitting a metal pipe with a hammer.

Naturally, the child began to cry after hearing the loud noise. After repeatedly pairing the white rat with the loud noise, Albert began to expect a frightening noise whenever he saw the white rat. Soon, Albert began to cry simply after seeing the rat.

It's a textbook example of how classical conditioning works. In some cases, these frightening experiences can cause a lasting fears, such as with phobias.

Classical Conditioning in the Little Albert Experiment

The Little Albert experiment is a great example of how classical conditioning can be used to condition an emotional response. Here's how the process works:

• Neutral Stimulus: A stimulus that does not initially elicit a response (the white rat).
• Unconditioned Stimulus: A stimulus that elicits a reflexive response (the loud noise).
• Unconditioned Response: A natural reaction to a given stimulus (fear).
• Conditioned Stimulus: A stimulus that elicits a response after repeatedly being paired with an unconditioned stimulus (the white rat).
• Conditioned Response: The response caused by the conditioned stimulus (fear).

Stimulus Generalization in the Little Albert Exerpiment

In addition to demonstrating that emotional responses could be conditioned in humans, Watson and Rayner also observed a phenomenon known as stimulus generalization.

After conditioning, Albert feared not just the white rat, but a wide variety of similar white objects as well. His fear included other furry objects, including Raynor's fur coat and Watson wearing a Santa Claus beard.

Criticism and Ethical Problems With the Little Albert Experiment

While the experiment is one of psychology's most famous and is included in nearly every introductory psychology course, it is widely criticized for several reasons. First, the experimental design and process were not carefully constructed. Watson and Rayner did not develop an objective means to evaluate Albert's reactions, instead of relying on their own subjective interpretations.

What Happened to Little Albert?

The question of what happened to Little Albert has long been one of psychology's mysteries. Before Watson and Rayner could attempt to "cure" Little Albert, he and his mother moved away. Some envisioned the boy growing into a man with a strange phobia of white, furry objects.

In 2009, researchers published the results of their attempt to track down the boy's identity. As reported in American Psychologist, a seven-year search led by psychologist Hall P. Beck led to the discovery of a child the researchers believed might be Little Albert. After tracking down and locating the original experiments and the possible identity of the boy's mother, it was suggested that Little Albert was actually a boy named Douglas Merritte.

Unfortunately, the researchers discovered that Douglas had died on May 10, 1925, at the age of six, of hydrocephalus (a build-up of fluid in his brain), which he had suffered from since birth.

In 2012, Beck and Alan J. Fridlund reported that Douglas was not the healthy, normal child Watson described in his 1920 experiment. Instead, they suggested that Watson may have known about and deliberately concealed the boy's neurological condition. If true, these findings would have cast a shadow over Watson's legacy, and deepened the ethical and moral issues of this well-known experiment.

Takeaways

While experts continue to debate the true identity of the boy at the center of Watson's experiment, there is little doubt that Little Albert left a lasting impression on the field of psychology. The experiments contributed to our understanding of the classical conditioning process. It also demonstrated that fear could be conditioned, which has helped mental health experts better understand how conditions like specific phobias and post-traumatic stress disorder form.
