fully intending to follow his father into the priesthood。 Nevertheless； after reading several books on
physiology； he changed his mind and decided on a career in the natural sciences。 Though he
encountered resistance at home； he entered the University of St。 Petersburg and obtained his basic
degree in physiology in 1875。
Pavlov’s research for the next 20 years was concerned primarily with the study of digestive
processes； and it was for his work in this area that he won the Nobel Prize in 1904。 It was in the
course of directing a number of experiments on the digestive glands that he first became aware of
the significance of the conditioned response。 He had been working with dogs as experimental
animals in an effort to establish the precise function of saliva in the digestive process； when he
noticed that many of the dogs secreted saliva even before meat was administered to them。 He
quickly determined that this “psychic response” occurred whenever the dogs either had a
preliminary glimpse of the food or heard the approaching footsteps of the lab assistant who fed
them。
This was so unexpected a phenomenon that he decided to pursue the process as a physiological
problem； receiving generous funding for the enterprise when the Soviet government came to power。
The new regime was anxious to push forward biological and behavioral research； and there was in
Pavlov； Nobel laureate and brilliant experimentalist； a man who could bring the Soviet Union into
the vanguard of scientific research。 A large number of colleagues and assistants joined Pavlov in
his work； thus establishing the longest…lived research project in the history of psychology。 The
Pavlovian paradigm is still used as the major approach to the study of psychology in the Soviet
Union。

CHAPTER 7： LEARNING AND BEHAVIOR ANALYSIS
Burrhus Frederic Skinner （1904—1990）
B。 F。 Skinner was born in Susquehanna； Pennsylvania； the son of a lawyer。 He attended Hamilton
College where he majored in English； hoping to bee a writer。 During his last year at Hamilton；
Skinner sent some short stories he had written to the poet Robert Frost； hoping for some helpful
criticism。 Much to Skinner’s surprise； Frost replied enthusiastically； encouraging the young author
to pursue a writing career。 Skinner took the advice seriously and set aside a block of time following
graduation in which to apply himself to his chosen discipline。 In looking back on that year； Skinner
wryly mented that while he did indeed write well； he also discovered that he had nothing
important to say。
To remedy that situation； he returned to academia as a graduate student in psychology。 He had
done much reading during his year away from school； and in the course of it； had discovered the
works of John B。 Watson。 The story of Watson’s pioneering efforts excited Skinner’s interest and
thus determined his decision to study psychology。 Skinner was accepted at Harvard and earned
his Ph。D。 in experimental psychology in 1931。 He continued with postdoctoral work until 1936；
when he accepted a teaching position at the University of Minnesota。 Throughout this period；
Skinner had been formulating and testing his theories on conditioning。 So impressive were the
results he achieved in controlling the behavior of laboratory animals； the U。S。 government
employed him in a top…secret project during World War II。 Skinner was given funding to condition
pigeons to guide missiles directly down the smokestacks of warships。
After the war； Skinner did not hesitate to apply the techniques he had developed to human
participants。 On moving to Indiana University as chairman of its new psychology department； he
constructed his famous “air crib”； a sound…proofed； germ…free “box” enclosed in clear plastic and
intended as an environment in which infants could spend much of their time。 In 1948； Skinner
returned to Harvard University as a member of the faculty。 There he developed the Skinner Box； a
chamber in which animal behavior （particularly that of rats and pigeons） could be precisely
recorded and prepared for statistical analysis。 The apparatus had an immediate impact on
experimental laboratories in universities across the country。
Skinner became convinced that the learning techniques he had hit on with his methodology could
be translated to the environment of the classroom； and so spent most of the 1950s perfecting his
programmed teaching modules for schoolchildren。 With these； children could acquire information
and skills while being led through a series of questions； each of their correct responses eliciting a
reinforcing confirmation。
Throughout his career； Skinner published prolifically； and the American Psychological Association
honored him for his immense contribution with their Distinguished Scientific Contribution Award
in 1958。 Though he retired as the Edgar Pierce Professor of Psychology at Harvard； Skinner did not
bee idle。 In the decade before his death； he published his autobiography； Particulars of My Life； a
book on aging； in 1983； and continued to be active； writing； and espousing the controversial brand
of behaviorism for which he became famous。
Edward Lee Thorndike （1874—1949）
Edward Thorndike was born in Williamsburg； Massachusetts； the son of a lawyer。 He graduated
from Wesleyan University in Connecticut in 1875； but showed no interest in psychology until he
read William James’ Principles of Psychology； after which he decided to study under James at
Harvard。 Thorndike’s initial experiments were conducted in the basement of James’ home。 When
James lost interest in experimental work； Thorndike left Harvard and obtained his Ph。D。 at
Columbia University。 There he conducted his famous experiments on cats in puzzle boxes。

PSYCHOLOGY AND LIFE
Thorndike was among psychology’s most prolific and versatile scientists； publishing more than
500 monographs； books； and articles during his career。 He applied his considerable intellect to a
wide range of topics； including individual differences； attitudes； vocabulary； intelligence； learning；
and memory。 His many writings include the influential book； Animal Intelligence。
TIMELINE

1898 Edward L。 Thorndike proposed that learning was controlled by its consequences；
an idea that he termed the ”Law of Effect。”
1904 Ivan P。 Pavlov； a Russian physiologist； discovered classical conditioning。
1905 Albert Einstein developed his theory of relativity。
1909 Henry Ford began the mass production of the Model T； and auto travel became a
democratic experience。
1913 John B。 Watson published Psychology as the Behaviorist Views It； establishing his
brand of behaviorism as an approach to studying learning and behavior。
19141918
World War I was fought。
1927 Wolfgang K。hler coined the term “insight” to describe a kind of learning in which
the organism suddenly arrived at a solution to a problem。
1932 Edward C。 Tolman published Purposive Behavior in Animals and Men； a book
outlining one of the earlier cognitive theories of learning。
1938 B。 F。 Skinner published The Behavior of Organisms； a book describing the basic
principles of operant conditioning。
1943 Penicillin was discovered。
1953 B。 F 。 Skinner published Science and Human Behavior； a book that applied the basic
principles of operant conditioning to understanding human learning and
behavior。
1959 David Premack discovered that preferred activities can be used to reinforce less
preferred activities； an idea soon to bee known as the Premack Principle。
1961 Richard J。 Herrnstein proposed the matching law； the notion that behavior in a
choice situation matches the frequency of reinforcement associated with each of
the choice alternatives。
1962 Albert Bandura proposed his model of social learning theory； a cognitive account
of how imitation and modeling influence learning。
1966 John Garcia and Robert A。 Koelling discovered that animals learn to associate
some stimuli with the consequences of their behavior more quickly than other
stimuli； reflecting natural biases in how animals adapt to their en
