While historically presented as a healthy infant, later analysis of medical records and film footage suggests Little Albert (likely Douglas Merritte) suffered from congenital obstructive hydrocephalus, meningitis, and optic nerve atrophy, conditions causing neurological impairment that affected his movements and vision during the famous conditioning experiment.
They verify that Merritte indeed had congenital hydrocephalus, and recounted in disturbing detail treatments the child was subjected to during his first year of life, including repeated cranial and lumbar punctures to reduce fluid buildup in the brain.
In the winter of 1919/20, Watson and his graduate assistant, Rosalie Alberta Rayner, attempted to condition a baby boy, Albert B., to fear a white laboratory rat (Watson & Rayner, 1920). They later reported that the child's fear generalised to other furry objects.
Conducted by behaviorist John B. Watson and Rosalie Rayner, it involved conditioning a young boy, Little Albert, to fear a white rat by pairing it with a loud, frightening noise. Over time, this fear generalized to similar objects, revealing how emotional responses can be learned.
Young children cannot consent to being included in experiments, and informed consent was not obtained in Albert's case. Additionally, the conditioning of the irrational fear was never reversed in Albert. For these reasons, the psychology experiment is often considered unethical and abusive.
After pairing the noise with the stimuli several times, little Albert began to cry only after seeing the rat. Although the experiment is still very famous, it raises several ethical concerns: There was no informed consent (from the parents or the child) and the principle of 'do no harm' was violated.
What do the two accounts mean for the fate of Little Albert? If he was Douglas Merritte, then the story is a sad one – the boy died at age six of hydrocephalus.
Following these final tests, Albert's mother removed him from the hospital where the experiment had been conducted. (According to their own account, Watson and Rayner knew a month in advance the day that Albert would no longer be available to them.)
Pavlov introduced the ringing of the bell as a neutral stimulus. Over time, a neutral stimulus can become a conditioned stimulus, which eventually triggers a conditioned response. In Pavlov's experiment, the ringing of the bell became the conditioned stimulus, and salivation was the conditioned response.
Classical conditioning often happens naturally. (Classical is one a thing that isn't associated with a response is repeatedly paired with something that does produce a response begins to produce that response. An example- baby cries, mom puts baby to breast baby starts to nurse, milk comes out.
Abstract. In 1920, John B. Watson and Rosalie Rayner attempted to condition a phobia in a young infant named "Albert B." In 2009, Beck, Levinson, and Irons proposed that Little Albert, as he is now known, was actually an infant named Douglas Merritte.
Justin Timberlake: Arachnophobia
He is scared of spiders. Arachnophobia is a prevalent phobia that this fear reflects. Apart from spiders, Timberlake shies away from snakes and sharks.
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 demonstrating fear.
He thought that a phobia could be created and then extinguished through the process of Classical Conditioning. Up till this point, research into Classical Conditioning had been carried out on animals. Watson believed the same principles of association and generalisation applied to human behaviour.
When an unconditioned stimulus, like the loud noise, is paired with a neutral item, such as a teddy bear, the teddy bear can become a conditioned stimulus. Meaning that someone may jump when they see a teddy bear because they have been conditioned to recall the loud noise response.
Rosalie Rayner is largely remembered for assisting John B. Watson – the 'father' of behaviourism – in his infamous 'Little Albert' experiments, a milestone in the dominance of behaviourism in psychology for a generation.
More recently, in his textbook, The Essentials of Conditioning and Learn- ing, Domjan (1996) began his chapter "Pavlovian Excitatory Condition- ing" with a series of tantalizing statements, the first of which was, "Did you know that: Pavlov never rang a bell in his experiments" (p. 37).
Contemporary perspectives have expanded upon his work, acknowledging the and individual . Nonetheless, Pavlov's contributions remain foundational to the study of learning and behaviour, and his theory continues to be an integral part of the curriculum for most students studying psychology.
Watson's daughter from his first marriage, Mary Ickles Watson, and his two sons with Rayner, William Rayner Watson and James Broadus Watson, all attempted suicide. William died by suicide in 1954. During the latter part of his life, Watson's already poor relationships with his children progressively worsened.
Applying principles from classical conditioning, Watson argued that emotions like fear, love, and anger were not inborn but learned through association. His Little Albert experiment was, in his view, proof that emotional responses could be conditioned.
Little Albert was conditioned by John B. Watson to fear a white rat. Eventually, however, Albert became fearful of any stimulus that looked white and furry. He became scared not only of rats, but also of rabbits, and even Santa Claus's beard.
This Albert was not brain-damaged and was easy-going, though (likely coincidentally, given how Albert's fears would diminish between sessions) he had an aversion to dogs! Albert died in 2007, without ever knowing of his early life in a hospital residence, or of his apparent part in psychology's history.
After suffering from bouts of illness throughout his life, Albert died on 14 December 1861. He was 42 years old. It's thought he died from typhoid fever or a flare up of a stomach condition, like Crohn's Disease. “My life as a happy one is ended,” wrote Victoria.
The outcome of John Watson's Little Albert experiment was that classical conditioning is possible in humans, since the boy learned to associate a neutral stimulus (white rat) with a fearful stimulus (loud bang) to be scared of the white rat.
