3. Ivan Pavlov
 Ivan Pavlov was born in Russia
 A son of a priest
 He abandoned his early
theological schooling to study Science.
 He studied Chemistry and Physiology at the
University of St.Petersburg and received the
degree of candidate of Natural Sciences in
1875.
 He enrolled at the Imperial Medical Academy in
St. Peterburg, completing his graduate
dissertation on the centrifugal nerves of the
heart in 1883.

4. Contributions and Achievements
 In 1890, Pavlov took charge of the Department of
Physiological.
 He was also named professor of Pharmacology at
the Imperial Medical Academy.
 After he finish his doctorate at that school, he
focused on the digestive secretion of dogs.
 He won the 1904 Nobel Prize

5. What is Classical Conditioning?
 Classical Conditioning- A learned
reflex/response that you do when
evoked by a stimulus
 Involves learning new behavior via the
process of association.

8. What is Classical Conditioning?
 Unconditioned Stimulus (UCS) produces an
unconditioned response (UCR)
 Neutral Stimulus (NS)- Does not yet produce an
automatic response until it is paired with the (UCS)
 Conditioned Stimulus (CS)

9. Classical Conditioning a Fear Response
 One of the most famous examples of
classical conditioning was John B. Watson's
experiment in which a fear response was
conditioned in a young boy known as “Little
Albert”. The child initially showed no fear of a
white rat, but after the presentation of the rat
was paired repeatedly with loud, scary
sounds, the child would cry when the rat was
present. The child's fear also generalized to
other fuzzy white objects.

10. Elements of Classical Conditioning in
the Little Albert Experiment
The Little Albert experiment presents and
example of how classical conditioning can be
used to condition an emotional response.
 Neutral Stimulus: The white rat
 Unconditioned Stimulus: The loud noise
 Unconditioned Response: Fear
 Conditioned Stimulus: The white rat
 Conditioned Response: Fear
