Introduction of John Broadus Watson
Father of American Behaviorist theory His work based on Pavlov experiments on
dogs digestive system He researched on classical conditioning Watson believed that all individual
differences in behavior were due to different experiences of learning.

John Watson proposed that the process of classical conditioning was able to explain all aspects of human psychology.
Everything from speech to emotional responses were simply patterns of stimulus and response.
Watson denied completely the existence of the mind or consciousness.

Famous quotation by Watson
"Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select - doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations and the race of his ancestors”

Aspects of Watson's theory
He opposed mentalistic concepts He used contiguity to explain learning He considered emotion to be just another
example of classical conditioning. He rejected the notion of individual
differences

Cont…
He thought complex behaviors came about through combinations of identifiable reflexes
He was a chief proponent of "nurture" and believed that all human differences were the result of learning
He believed that practice strengthens learning

Stage 1: Before Conditioning:
In this stage, the unconditioned stimulus (UCS) produces an unconditioned response (UCR)in an organism.
In basic terms, this means that a stimulus in the environment has produced a behavior / response which is unlearned and
therefore is a natural response which has not been taught

Neutral Stimulus
This stage also involves another stimulus which has no effect on a person and is called the neutral stimulus (NS).
The NS could be a person, object, place, etc. The neutral stimulus in classical conditioning
does not produce a response until it is paired with the unconditioned stimulus.

Stage 2: During Conditioning:
During this stage a stimulus which produces no response (i.e. neutral) is associated with the unconditioned stimulus at which point it now becomes known as the conditioned stimulus (CS).

However, one trail learning can happen on certain occasions when it is not necessary for an association to be strengthened over time

Stage 3: After Conditioning:
Now the conditioned stimulus (CS) has been associated with the unconditioned stimulus (UCS) to create a new conditioned response (CR).

Watson Experiment
Watson was interested in taking Pavlov's research further to show that emotional reactions could be classically conditioned in people.
The participant in the experiment was a child Known as Little Albert
![Page 15: John watson learning theory](https://reader035.fdocuments.us/reader035/viewer/2022062523/58ee99131a28ab34398b4627/html5/thumbnails/15.jpg)
Little Albert
A 9 month baby Watson exposed the child to a series of
stimuli including a white rat, a rabbit, a monkey, masks and burning newspapers and
observed the boy's reactions

Stage 1 Before Conditioning
The boy initially showed no fear of any of the objects he was shown.

Stage 2 During Conditioning
The next time Albert was exposed the rat, Watson made a loud noise by hitting a metal pipe with a hammer.

Stage 3 After Conditioning
Naturally, the child began to cry after hearing the loud noise.
After repeatedly pairing the white rat with the loud noise, Albert began to cry simply after seeing the rat.

Elements of Classical Conditioning
Neutral Stimulus: The white rat Unconditioned Stimulus: The loud noise Unconditioned Response: Fear Conditioned Stimulus: The white rat Conditioned Response: Fear
