Ivan Pavlov, a Russian scientist, discovered classical conditioning while studying the digestive system of dogs. He found that dogs deprived of food would salivate when his assistant entered the room. Through further investigation, Pavlov established that a stimulus that initially produces no response can acquire the ability to produce a response through repeated pairing with another stimulus that does elicit a response. Classical conditioning involves an unconditioned stimulus, unconditioned response, conditioned stimulus, and conditioned response.

3. Classical conditioning was the first type of learning to be discovered and
studied within the behaviorist tradition. Conditioning is a kind of
response build up through repeated exposure.
The major theorist in the development of classical conditioning is
Ivan Pavlov, a Russian scientist trained in biology and medicine .
Pavlov was studying the digestive system of dogs and became intrigued
with his observation that dogs deprived of food began to salivate when
one of his assistants walked into the room.
He began to investigate this phenomena and established the laws
of classical conditioning
4. Conditioning -- a stimulus that initially produces no response can
acquire the ability to produce one.
Learning occurs through pairing in time and place of one stimulus
with another stimulus that produces a response.
This is a kind of associative shifting, but the response is involuntary.
The classical conditioning theory is based on the assumption that
learning is developed through the interactions with the
environment. Also, the environment shapes the behavior and
internal mental state such as thoughts, feelings, emotions do not
explain the human behavior.

8. An organism learns to transfer response from one
stimulus to a previously neutral stimulus. Classical
conditioning is comprised of four elements:
Unconditioned Stimulus (US): Which invariably causes
to react in a way.
Unconditioned Response (UR): Takes place when the
US is presented.
Conditioned Stimulus (CS): The object that does not
bring about the desired response
Conditioned Response (CR): a particular behavior that
an organism learns to produce, when the CS is
presented.
9. Classical conditioning (also known as
Pavlovian or respondent conditioning)
refers to a learning procedure in which
a biologically potent stimulus (e.g.
food) is paired with a previously neutral
stimulus (e.g. a bell). It also refers to
the learning process that results from
this pairing, through which the neutral
stimulus comes to elicit a response (e.g.
salivation) that is usually similar to the
one elicited by the potent stimulus.
10. Acquisition – This is the initial stage of learning when a response is first established and
gradually strengthened. A neutral stimulus is repeatedly paired with an unconditioned
stimulus to get a conditioned response.
Stimulus generalization – stimuli like the CS become able to evoke the conditioned
response.
Extinction – if the UCS and CS are not paired, the CS loses its ability to produce a
conditioned response.
Spontaneous recovery – an extinguished CS briefly returns but quickly goes away again.
11. Figure 8.4 Acquisition, Extinction, and Spontaneous Recovery.
Acquisition: The CS and the US are repeatedly paired together and
behaviour increases. Extinction: The CS is repeatedly presented alone,
and the behaviour slowly decreases. Spontaneous recovery: After a
pause, when the CS is again presented alone, the behaviour may again
occur and then again show extinction.
12. • Fear, love towards a particular subject is created through
conditioning.
• A teacher, method of teaching or harsh treatment of his
students, create strong dislike among them towards subject.
• The theory of classical conditioning emphasizes that the
students should be exposed to positive stimuli in order to
develop desirable habits, interest and attitudes in them.
