Cognitive Psycholog y
Cognitive psychology includes such topics as mem-
ory, concept formation, attention, reasoning, prob-
lem solving, judgment, and language. Clearly cogni-
tive psychology is very popular within contemporary
psychology. However, in psychology’s long history
some form of cognition has almost always been em-
phasized. The few exceptions included the material-
istic philosophies or psychologies of Democritus,
Hobbes, Gassendi, La Mettrie, Watson, and Skinner,
which denied the existence of mental events. The
schools of voluntarism and structuralism concen-
trated on the experimental study of cognition, and
the school of functionalism studied both cognition
and behavior. The supposed sterility of the research
on cognition performed by members of these schools
prompted Watson to create the school of behavior-
ism. Thus to say, as is common, that psychology is
be-
coming
more cognitively oriented is inaccurate, be-
cause with only a few exceptions it has always been
cognitively oriented. But there was a period from
about 1930 to about 1950 when radical behaviorism
was highly influential, and when it was widely be-
lieved that cognitive events either did not exist or, if
they did, were simply by-products (epiphenomena)
of brain activity and could be ignored. As long as
these beliefs were dominant, the study of cognitive
processes was inhibited.
We mention here only a few of the people and
events that helped loosen the grip of radical behav-
iorism, thus allowing cognitive psychology to gain its
current popularity. For more see, for example, Ma-
honey, 1991, pp. 69–75.
Developments before 1950
Throughout most of psychology’s history human
attributes were studied philosophically. J. S. Mill
(1843/1988) set the stage for psychology as an exper-
imental science and encouraged the development of
such a science. Fechner (1860/1966) took Mill’s lead
and studied cognitive events (sensations)
experimen-
tally.
Ebbinghaus (1885/1964), under the influence
of Fechner, studied learning and memory experimen-
tally. William James’s
The Principles of Psychology
(1890) cited considerable research on cognition and
suggested many additional research possibilities. Sir
Frederick Charles Bartlett (1886–1969), in
Remem-
bering: A Study in Experimental and Social Psychology
(1932), demonstrated how memory is influenced
more by personal, cognitive themes or schema than
by the mechanical laws of association. In other
words, he found that information is always encoded,
stored, and recalled in terms of an individual’s pre-
conceptions and attitudes.
As early as 1926 Jean Piaget (1896–1980) began
publishing research on intellectual development.
During his long life Piaget published more than 50
books and monographs on genetic epistemology or
developmental intelligence. In general, Piaget dem-
onstrated that a child’s interactions with the en-
vironment become more complex and adaptive as
its cognitive structure becomes more articulated
through maturation and experience. According to
Piaget, the cognitive structure comprises schemata
that determine the quality of one’s interactions with

the environment. For the young child, these sche-
mata are sensory motor reflexes that allow only the
most rudimentary interactions with the environ-
ment. With maturation and experience, however,
the schemata become more cognitive and allow in-
creasingly complex (intelligent) interactions with
the environment. For Piaget, it was always the
schemata contained within the cognitive structure
that determine what kinds of interactions with the
environment are possible. Piaget’s theory followed
the rationalistic rather than empiricistic tradition.
More particularly, because it stressed the importance
of schemata for determining a person’s reality, it fol-
lowed the Kantian tradition. Piaget wrote books
about the child’s conceptions of causality, reality,
time, morality, and space, all showing the influence
of Kant’s proposed categories of thought. It is inter-
esting to note that Piaget was an even more prolific
writer than Wundt. In chapter 9 we noted that
Wundt published 53,735 pages in his lifetime, or
2.20 pages a day; Zusne and Blakely (1985) report
that Piaget published 62,935 pages in his lifetime, or
2.46 pages a day.
As we have seen, Gestalt psychology and radical
behaviorism were created about the same time (1912
and 1913, respectively), and the cognitively oriented
Gestalters were a constant thorn in the side of the
behaviorists. Also, during the 1930s and 1940s,
methodological behaviorists such as Hull and Tol-
man were willing to postulate events that intervene
between stimuli (S) and responses (R). For Hull,
these intervening variables are mainly physiological,
but for Tolman they are mainly cognitive.
In 1942 Carl Rogers (1902–1987) published
Counseling and Psychotherapy: Newer Concepts in
Practice
that challenged both radical behaviorism
and psychoanalysis by emphasizing the importance
of conscious experience in the therapeutic situation.
In 1943 Abraham Maslow (1908–1970) first pro-
posed his theory of human motivation based on the
hierarchy of needs. In spite of the efforts of individu-
als such as Rogers and the popularity of behaviorism
during the 1920s, 1930s, and 1940s, psychoanalysis
remained very influential, especially among clinical
psychologists and psychiatrists. Donald Hebb (1904–
1985) was an early critic of radical behaviorism and
did much to reduce its influence. In his book
The Or-
ganization of Behavior
(1949), Hebb not only sought
biological explanations of behavior but also urged
the study of cognitive processes. As we shall see in
chapter 19, Hebb continued to encourage the devel-
opment of both physiological and cognitive psychol-
ogy in the 1950s and 1960s. In 1949 Harry Harlow
(1905–1981) published “The Formation of Learning
Sets,” which provided evidence that monkeys em-
ploy mental strategies in their solving of discrimina-
tion problems. This finding was clearly in conflict
with the behavioristic psychology of the time.
In 1948 Norbert Wiener (1894–1964) defined
cybernetics
as the study of the structure and function
of information-processing systems. Of particular in-
terest to Wiener was how mechanical or biological
systems can achieve a goal or maintain a balance by
automatically utilizing feedback from their activi-
ties. The automatic pilots on airplanes and ther-
mostats are examples of such systems. Soon it was re-
alized that purposive human behavior could also be
explained in such mechanistic terms, thus overcom-
ing the argument that the study of purposive (goal-
directed) behavior must necessarily be subjective. In
1949 Claude E. Shannon, working for the Bell Tele-
phone Laboratories, and Warren Weaver, working
for the Rockefeller Foundation, were seeking ways of
improving the purity of messages between the time
they are sent and the time they are received. The
work of Shannon and Weaver began what came to
be called
information theory.
Information theory
notes the various transformations information un-
dergoes as it enters a communication system, as it
operates within the system, and as it leaves the sys-
tem. As we will see later in this chapter, informa-
tion-processing psychology, like information theory,
attempts to understand those structures, processes,
and mechanisms that determine what happens to in-
formation from the time it is received to the time it
is acted on.
Developments during the 1950s
According to Bernard Baars (1986), “There is little
doubt that George A. Miller... has been the single
most effective leader in the emergence of cognitive

George A. Miller
In 1951 Karl Lashley (1890–1958) argued that
the explanation of serial or chained behavior, offered
by the behaviorists, that stressed the importance of
external stimulation was insufficient. Rather, he said,
such organized behavior could emanate only from
within the organism. In an influential publication,
“Drives and the C.N.S. (Conceptual Nervous Sys-
tem)” (1955), Hebb continued to show his willing-
ness to “physiologize” about cognitive processes and
thus to engage in battle with the behaviorists. Leon
Festinger (1919–1989) noted that the ideas one en-
tertains may be compatible with or incompatible
with one another. Incompatibility exists, for exam-
ple, if one is engaged in an obviously boring task but
is encouraged to describe it as exciting, or if one
smokes cigarettes and yet believes that smoking
causes cancer. When ideas are incompatible, a state
of dissonance exists that motivates a person to
change beliefs or behavior. In the cases above, for ex-
ample, a person could reduce cognitive dissonance
by telling the truth about the task being boring or be-
come convinced that the task is actually exciting.
With the smoker, cognitive dissonance could be re-
duced by quitting the habit or by believing there re-
ally is no proven relationship between smoking and
cancer. Festinger’s influential book
A Theory of Cog-
nitive Dissonance
(1957) made no reference to behav-
ioristic ideas. In the early 1950s Jerome Bruner be-
came interested in thinking and concept formation
and in 1955 he assisted Sir Frederic Bartlett in ar-
ranging, at Cambridge, one of the first conferences
on cognitive psychology (Bruner, 1980). In 1956
Bruner, along with Jacqueline Goodnow and George
Austin, published
A Study in Thinking,
which em-
phasized concept learning. Although concept learn-
ing had been studied earlier by Hull and Thorndike,
their explanations of such learning were couched
in terms of passive, associationistic principles. The
explanation offered by Bruner and his colleagues
stressed the active utilization of cognitive strategies
in such learning. In 1959 Tracy and Howard Kendler
analyzed childrens’ discrimination learning in terms
of concept utilization rather than in terms of behav-
ioristic principles. Also in 1959 Chomsky published
his influential review of Skinner’s book
Verbal Learn-
ing
(1957). We will have more to say about Chom-
psychology” (p. 198). Miller remembers that, during
the 1950s, “‘cognition’ was a dirty word because cog-
nitive psychologists were seen as fuzzy, hand-waving,
imprecise people who really never did anything that
was testable” (p. 254). Miller argued that modern
cognitive psychology began during a symposium on
information theory sponsored by the Massachusetts
Institute of Technology on September 10–12, 1956.
During the symposium, Allen Newell and Herbert
Simon presented papers on computer logic, Noam
Chomsky presented his views on language as an in-
herited, rule-governed system, and Miller described
his research demonstrating that people can discrimi-
nate only seven different aspects of something—for
example, hues of color or pitches of sound. Also,
people can only retain about seven meaningful units
of experience (chunks) such as numbers, words, or
short sentences. Miller summarized his research in
his influential article “The Magical Number Seven,
Plus or Minus Two: Some Limits on Our Capacity for
Processing Information” (1956). Participants in the
MIT symposium did much to bring the terminology
and concepts of information theory and cybernetics
into psychology. At about the same time, the English
psychologist Donald Broadbent (1957, 1958) was
doing the same thing. Crowther-Heyck (1999) dis-
cusses the importance of Miller’s work in the early
development of cognitive psychology.

Also during the 1950s, humanistic theorists such
as Maslow, Kelly, Rogers, and May continued devel-
oping their ideas, as did the Gestalt psychologists
and the psychoanalysts.
ioristic phase and it produced precise, factual knowl-
edge and scientific rigor that had not previously ex-
isted in psychology. However, in their effort to be
entirely objective the behaviorists had minimized or
banished such topics as thought, imagery, volition,
and attention. Hebb urged that the second phase
of psychology’s revolution use the scientific rigor
promoted by the behaviorists to study the long-
neglected cognitive processes. Concerning the sec-
ond phase of the revolution, Hebb (1960) said, “The
camel already has his nose inside the tent” (p. 741).
He noted the works of Festinger, Broadbent, Kendler
and Kendler, Miller, Galanter, and Pribram as good
starts toward a rigorous cognitive psychology. He was
especially impressed by the possibility of the com-
puter acting as a model for studying cognitive pro-
cesses. He prophesized that such a model will be-
come “a powerful contender for the center of the
stage” (1960, p. 741). Hebb’s preferred approach to
studying cognitive processes was to speculate about
their biological foundations. We will have more to
say about Hebb when we consider psychobiology in
chapter 19.
In 1962 and 1963 M. D. Egger and Neal Miller
demonstrated that, contrary to tradition, classical
conditioning phenomena could not be explained in
terms of associative principles alone. Rather the in-
formation conveyed by the stimuli involved had to
be taken into consideration. In 1967 Ulric Neisser,
who studied with George Miller, published his influ-
ential book
Cognitive Psychology,
in which Neisser
defined the term cognition as, “All the processes by
which... sensory input is transformed, reduced,
elaborated, stored, recovered and used” (p. 4). Also
in this book, Neisser attempted to integrate research
on such topics as perception, concept formation,
meaning, language, and thinking, using a few con-
cepts adopted primarily from information theory.
Once the grip of behaviorism—especially radical
behaviorism—had been loosened many earlier ef-
forts in experimental cognitive psychology were ap-
preciated. About the influence of Ebbinghaus,
Michael Wertheimer (1987) said, “His seminal ex-
periments can . . . be viewed as the start of what was
to become the currently popular field of cognitive
Developments after the 1950s
In 1960 Miller and his colleagues Eugene Galanter
and Karl Pribram published
Plans and the Structure of
Behavior,
in which it was argued that cybernetic con-
cepts (such as information feedback) explain human
goal-directed behavior better than S–R concepts do,
and at least as objectively. Also in 1960 Miller and
Jerome Bruner founded the Center for Cognitive
Studies at Harvard. In addition to promoting re-
search on cognitive processes, the center did much
to popularize the ideas of Piaget among U.S. psychol-
ogists. In 1962 Miller published an article entitled
“Some Psychological Studies of Grammar” (1962a),
which introduced Chomsky’s nativistic analysis of
language into psychology. In 1890 William James
had defined psychology as “the science of mental
life”; in 1962 Miller purposefully used James’s defini-
tion as the title of his text
Psychology: The Science of
Mental Life
(1962b).
In 1963 as evidence of how far cognitive psychol-
ogy had progressed and in recognition of Miller’s role
in that progress, Miller was presented a Distin-
guished Scientific Contribution Award by the APA.
Miller served as president of the APA in 1969, re-
ceived the Gold Medal for Life Achievement in Psy-
chological Science from the American Psychological
Foundation (APF) in 1990, and was Awarded a Na-
tional Medal of Science by President George Bush in
1991. Miller is currently professor emeritus and se-
nior research psychologist at Princeton University.
In 1959 Donald Hebb served as president of the
APA, and his presidential address “The American
Revolution” was published in 1960. In this address,
Hebb was referring not to America’s political revolu-
tion but to its psychological revolution. According
to Hebb, only one phase of the American revolution
in psychology had taken place. This was the behav-

psychology” (p. 78). Concerning the influence of
Gestalt psychology, Hearst (1979) said, “Present-day
cognitive psychology—with its emphasis on organi-
zation, structure, relationships, the active role of the
subject, and the important part played by perception
in learning and memory—reflects the influence of its
Gestalt antecedents” (p. 32). In an interview with
Baars, Neisser describes how Gestalt psychology in-
fluenced him:
but will act on that information only when one is
thirsty. For Tolman, this distinction between learn-
ing and performance was extremely important, and
it is also important in Bandura’s theory. (Hergen-
hahn & Olson, 2001, pp. 319–320)
(See Bandura, 1986, for an excellent summary of his
extensive research in
Social Cognitive Theory.
)
The journal
Cognitive Psychology
was founded in
1969, and within the next two decades 15 additional
journals were established featuring research articles
on such topics as attention, problem solving, mem-
ory, perception, language, and concept formation.
Interest in experimental cognitive psychology had
become so extensive that many believe a revolution,
or paradigm shift, had occurred in psychology (for
example Baars, 1986; Gardner, 1985; Sperry, 1993).
Others, however, suggest that contemporary cogni-
tive psychology represents a
return
to a kind of psy-
chology that existed before the domination of be-
haviorism. If anything, then, there occurred a
counterrevolution rather than a revolution (see Her-
genhahn, 1994b). Even George Miller, who, as we
have seen, was as responsible as anyone for the cur-
rent popularity of cognitive psychology, rejects the
idea that a revolution took place:
What seems to have happened is that many experi-
mental psychologists who were studying human
learning, perception, or thinking began to call
themselves cognitive psychologists without chang-
ing in any obvious way what they had always been
thinking and doing—as if they suddenly discovered
they had been speaking cognitive psychology all
their lives. So our victory may have been more
modest than the written record would have led you
to believe. ( Bruner, 1983, p. 126)
Robins, Gosling, and Craik (1999) note that the
popularity of cognitive psychology has increased dra-
matically over the last three decades. They agree
with Miller, however, that it is incorrect to refer to
this increased popularity as a “cognitive revolution.”
In any case, from the many forms of cognitive
psychology that existed prior to the 1970s, informa-
tion-processing psychology emerged as the dominant
form. Information-processing psychology is the kind
of cognitive psychology that took the computer
I . . . became particularly interested in Gestalt psy-
chology. It had an idealistic quality that appealed to
me. To the Gestalt psychologists human nature was
something wonderful, worth exploring, worth
knowing about. They were constantly doing battle
with the behaviorists, who seemed to see human
nature as a mere collection of conditioned re-
sponses or blind associations. From the Gestalt
viewpoint, the mind is something beautiful, well-
structured, in harmony with the universe. (Baars,
1986, p. 274)
And, regarding Piaget’s influence, Jerome Kagan
(1980) said, “With Freud, Piaget has been a seminal
figure in the sciences of human development”
(p. 246).
One of the most popular cognitive theories in
contemporary psychology is Albert Bandura’s
social
cognitive theory.
In several ways, Bandura’s theory
can be understood as a direct descendent of Tol-
man’s theory.
If one had to choose a theory of learning that is
closest to Bandura’s, it would be Tolman’s theory.
Although Tolman was a behaviorist, he used men-
talistic concepts to explain behavioral phenom-
ena... and Bandura does the same thing. Also,
Tolman believed learning to be a constant process
that does not require reinforcement, and Bandura
believes the same thing. Both Tolman’s theory and
Bandura’s theory are cognitive in nature, and nei-
ther are reinforcement theories. A final point of
agreement between Tolman and Bandura concerns
the concept of motivation. Although Tolman be-
lieved that learning was constant, he believed fur-
ther that the information gained through learning
was only acted on when there was reason for doing
so, such as when a need arose. For example, one
may know full well where a drinking fountain is
