Learned Through Classical Conditioning.
Yes, Watson’s experiment with Little Albert demonstrated that fears can be learned through classical conditioning. In the experiment, Little Albert was conditioned to fear a white rat by pairing it with a loud noise. After the experiment was complete, Little Albert had acquired a fear of the white rat, even when the loud noise was not present. This demonstrated that fears can be learned through classical conditioning.
Little Albert experiment
The Little Albert experiment was a study that mid-20th century psychologists interpret as evidence of classical conditioning in humans. The study is also claimed to be an example of stimulus generalization although reading the research report shows that fear did not generalize by color or tactile qualities . It was carried out by John B. Watson and his graduate student, Rosalie Rayner, at Johns Hopkins University. The results were first published in the February 1920 issue of the Journal of Experimental Psychology.
After observing children in the field, Watson hypothesized that the fearful response of children to loud noises is an innate unconditioned response. He wanted to test the notion that by following the principles of the procedure now known as “classical conditioning”, he could use this unconditioned response to condition a child to fear a distinctive stimulus that normally would not be feared by a child (in this case, furry objects). However, he admitted in his research article that the fear he generated was neither strong or lasting.
The aim of Watson and Rayner was to condition a phobia in an emotionally stable child. For this study they chose a nine-month old infant from a hospital. The child was referred to as “Albert” for the experiment. Watson followed the procedures which Ivan Pavlov had used in his experiments with dogs.
Before the experiment, Albert was given a battery of baseline emotional tests: the infant was exposed, briefly and for the first time, to a white rat, a rabbit, a dog, a monkey, masks (with and without hair), cotton, wool, burning newspapers, and other stimuli. Albert showed no fear of any of these items during the baseline tests.
For the experiment proper, by which point Albert was 11 months old, he was put on a mattress on a table in the middle of a room. A white laboratory rat was placed near Albert and he was allowed to play with it. At this point, Watson and Rayner made a loud sound behind Albert’s back by striking a suspended steel bar with a hammer each time the baby touched the rat. Albert responded to the noise by crying and showing fear. After several such pairings of the two stimuli, Albert was presented with only the rat. Upon seeing the rat, Albert became very distressed, crying and crawling away. Apparently, the infant associated the white rat with the noise. The rat, originally a neutral stimulus, had become a conditioned stimulus, and was eliciting an emotional response (conditioned response) similar to the distress (unconditioned response) originally given to the noise (unconditioned stimulus).
In further experiments, Little Albert seemed to generalize his response to the white rat. He became distressed at the sight of several other furry objects, such as a rabbit, a furry dog, and a seal-skin coat, and even a Santa Claus mask with white cotton balls in the beard. However, this stimulus generalization did not extend to everything with hair.
Watson’s experiment had many failings by modern standards. For example, it had only a single subject and no control subjects. Furthermore, such an experiment could be hard to conduct in compliance with current law and regulations, given the expected risks to the subject.
Albert was about one year old at the end of the experiment, and he reportedly left the hospital shortly thereafter. Though Watson had discussed what might be done to remove Albert’s conditioned fears, he chose not to attempt such desensitization with Albert, and it is thought likely that the infant’s fear of furry things continued post-experimentally.
Watson later gave a series of weekend lectures describing the Little Albert study. One of these lectures was attended by Mary Cover Jones, which sparked her interest in pursuing graduate work in psychology. Jones conducted an experiment to figure out how to eliminate fear responses in children and studied a boy named Peter, who was two years old. Peter shared similar fears of white rabbits and furry objects as Little Albert. Jones was able to increase Peter’s tolerance of white rabbits by exposing him to the animal, known as direct conditioning, and having Peter interact with children who were not afraid of the rabbit. Mary Cover Jones was the first psychologist to desensitize or uncondition a fear response and become known as the “Mother of Behavior Therapy”.
Identifying Little Albert
According to some textbooks[example needed], Albert’s mother worked in the same building as Watson and did not know the tests were being conducted. When she found out, she took Albert and moved away, letting no one know where they were going. A 2009 report, however, disputes that. The original report had stated that the baby’s mother was a wet nurse at the hospital, who may have felt coerced and unable to turn down a request for her baby to be used in Watson’s experiment. The claim of coercion was successfully challenged in an article published in the same journal as the coercion claim.
In 2009, psychologists Hall P. Beck and Sharman Levinson published an article in which they claimed to have discovered the true identity of “Albert B.” After reviewing Watson’s correspondence and publications, as well as research in public documents (such as the 1920 United States Census and state birth and death records), Beck argued that “Albert B.” was a pseudonym for Douglas Merritte, the son of Arvilla Merritte, then a woman who appears to have been a wet nurse at the Harriet Lane Home.
It was later found that Douglas Merritte had hydrocephalus, from which he died at the age of 6. With this condition, which is when there is an accumulation of cerebrospinal fluid on the brain, Merritte may have had severe trouble seeing at the time of the experiment, and this disputes the claim that the child in question was average and healthy. According to researchers who looked at this case years later, if Douglas Merritte was, indeed, Little Albert, his actions during the conditioning sessions align with signs of neurological impairment. This includes Little Albert’s use of hand-scooping, rather than grasping gestures typical of this age, as well as poor eye-scanning abilities and his lack of facial expressions. Other research has argued, however, that Douglas Merritte may not have been “Little Albert”, who may in fact have been young William Albert Barger.
William Albert Barger
The identity claimed by Beck, Levinson and Irons has been contested by psychology researchers Russ Powell and Nancy Digdon, who offer an alternative identity based on available data. William Barger had been born within a day of Merritte, was known by friends and family as “Albert”, which was his middle name, and his mother had also worked at the hospital where the experiment was conducted. In addition, his size and developmental condition much more closely matched the experiment’s documentation of the subject baby’s condition.
Through the use of a professional genealogist, the researchers learned Barger had died in 2007 at age 87 and identified one close living relative, a niece. In an interview, Barger’s niece stated that she and her uncle had been quite close throughout his life, acknowledged Barger’s antipathy toward dogs as a well-known fact that family members, particularly his wife, would tease him about (the researchers noted there was no way to determine whether or not this behavior was linked to Watson’s experiment). She also informed researchers of her uncle’s aversion to animals in general, not just dogs. Though it was not a particularly strong aversion, family members would often have to keep their dogs in a separate room when he visited. Outside of this, Barger’s niece stated that she did not recall any other phobias he may have had. The researchers concluded that Barger would have been unaware of his role as an infant test subject.
The experiment today would be considered unethical according to the American Psychological Association‘s ethic code, and legislation has been passed to prevent such potentially harmful experiments. In the early 1970s, following widely publicized cases of research abuse, the National Commission for the Protection of Human Subjects of Biomedical and Behavioral Research (NCPHS) was created to study issues surrounding the protection of humans in research. In 1979, the Commission issued a report entitled Ethical Principles and Guidelines for the Protection of Human Subjects of Research (commonly called the Belmont Report), which provided the ethical framework on which current federal regulations for the protection of human participants in research are based. Under the NCPHS standards set in the late 1970s, an experiment such as Watson’s would not have been allowed. Research with human participants is also regulated by the Health Insurance Portability and Accountability Act of 1996 and the Public Health Service Act. In addition, training of researchers in the use of human participants has been required by the National Institutes of Health since 2000.
A detailed review of the original study and its subsequent interpretations by Ben Harris (1979) stated:
Critical reading of Watson and Rayner’s (1920) report reveals little evidence either that Albert developed a rat phobia or even that animals consistently evoked his fear (or anxiety) during Watson and Rayner’s experiment. It may be useful for modern learning theorists to see how the Albert study prompted subsequent research … but it seems time, finally, to place the Watson and Rayner data in the category of “interesting but uninterpretable” results.
It is difficult to be certain exactly what happened during the Little Albert experiment since concrete evidence and scientific records are lacking. Though a film was shot during the experiment, textbooks interpret the movie differently. Various sources give contradicting accounts of events that took place, and they raise questions about exactly what stimuli were used, which stimuli the baby came to fear, and what happened to the child after the experiment. It was said that most textbooks “suffer from inaccuracies of various degrees” while referring to Watson and Rayner’s study. Texts often misrepresent, exaggerate, or minimize the range of Albert’s post-conditioning fears.
Other criticisms stem from the health of the child (cited as Douglas Merritte) who was not a “healthy”, “normal” infant as claimed in the study, but one who was very ill and had exhibited symptoms of hydrocephalus since birth—according to relatives he never learned to walk or talk later in life. The child would die five years after the experiment due to complications from the congenital disease. It is stated that the study’s authors were aware of the child’s severe cognitive deficit, abnormal behavior, and unusually frequent crying, but continued to terrify the sick infant and generalize their findings to healthy infants, an act criticized as academic fraud. These accusations were successfully challenged in the same journals that published the initial claims. The articles refuting the “sick baby” claim explain that the child was actually William (called Albert by his family) Barger, and that the child was, in fact, healthy.
