Evan Pavlov was a Russian physiologist who was awarded the Nobel Prize in 1904. He is known for his theory of classical conditioning. Through experiments with dogs, Pavlov observed that dogs learned to associate food with the presence of an external stimulus like a bell or light. When the bell was rung without food, the dogs would still salivate, showing they had learned to associate the bell with food. Pavlov's theory demonstrated that learning can occur through conditioning by linking a neutral stimulus with an unconditioned stimulus to elicit a desired response. His work formed the basis of behaviorism and was influential in psychology.

3. Conditioned Response
Theory/Learning by Conditioning.
 With his experiments on various animals like cats,
dogs, rats, Pavlov gave birth to the theory of
learning which is known as Conditioned
Response Theory or simply as by Conditioning.
 On the basis of his experiments Pavlov
considered learning as a habit formation based
on association and substitution. For example
presence of both artificial and natural stimuli for a
number of times, forming a habit.

4. What is ‘Conditioning’ ?
 The term ‘conditioning’ refers to building or
making of an environment that can bring change
into the behavior of a living being.
 It is a situation in which the behavior of any living
being is controlled or possessed. The thing which
alters or controls one’s behavior is called
Stimulus/stimuli.
 In the presence Stimulus the Response occurs.
Responses are of two types 1. Natural
(Unconditioned) and 2. Artificial/fabricated
(Conditioned)

5. Classical Conditioning
 It is a learning process whereby an
artificial stimulus is able to behave like a
natural stimulus when both natural and
artificial stimuli are presented together. In
this kind of learning, association plays a
great role since the individual responds to
an artificial stimulus because he
associates it with the natural stimulus.

6. Continues…
 The Conditioning Theory of Learning by
Pavlov involves the conditioning of
Respondent Behavior through a process
of stimulus association and substitution.
Here, the responses of the learners
become so much conditioned that
behaving in the same way or responding
similarly to a similar situation that he does
not care for the natural stimuli for evoking
the related natural response. As a result
the new substituted stimulus behaves like
original stimulus and is able to evoke the
desired response.
