Schools of Psychology
From the late 1800's until the 1930's, psychologists
were divided about what they should study and how they should study it.
Four major schools developed. These schools were
(1)
Structuralism,
(2)
Behaviourism,
(3) Gestalt
psychology, and
(4)
Psychoanalysis.
Structuralism grew out of the work of James, Wundt, and their
associates. These psychologists believed the chief purpose of psychology
was to describe, analyse, and explain conscious experience, particularly
feelings and sensations. The structuralists attempted to give a scientific
analysis of conscious experience by breaking it down into its specific
components or structures. For example, they identified four basic skin
sensations: warmth, cold, pain, and pressure. They analysed the sensation
of wetness as the combined experience of cold and smoothness.
The structuralists primarily used a method of research called
introspection. In this technique, subjects were trained to observe and
report as accurately as they could their mental processes, feelings, and
experiences.
Behaviourism was introduced in 1913 by John B. Watson, an
American psychologist. Watson and his followers believed that observable
behaviour, not inner experience, was the only reliable source of
information. This concentration on observable events was a reaction
against the structuralists' emphasis on introspection. The behaviourists
also stressed the importance of the environment in shaping an individual's
behaviour. They chiefly looked for connections between observable
behaviour and stimuli from the environment.
The behaviourist movement was greatly influenced by the work of the
Russian physiologist Ivan P. Pavlov. In a famous study, Pavlov rang a bell
each time he gave a dog some food. The dog's mouth would water when the
animal smelled the food. After Pavlov repeated the procedure many times,
the dog's saliva began to flow whenever the animal heard the bell, even if
no food appeared. This experiment demonstrated that a reflex--such as the
flow of saliva--can become associated with a stimulus other than the one
that first produced it--in this case, the sound of a bell instead of the
smell of food. The learning process by which a response becomes associated
with a new stimulus is called conditioning.
Watson and the other behaviourists realized that human behaviour could
also be changed by conditioning. In fact, Watson believed he could produce
almost any response by controlling an individual's environment.
During the mid-1900's, the American psychologist B. F. Skinner gained much
attention for behaviourist ideas. In his book Walden Two (1948), Skinner
describes how the principles of conditioning might be applied to create an
ideal planned society.
Gestalt psychology, like behaviourism, developed as a reaction
against structuralism. Gestalt psychologists believed that human beings
and other animals perceive the external world as an organized pattern, not
as individual sensations. For example, a film consists of thousands of
individual still pictures, but we see what looks like smooth, continuous
movement. The German word Gestalt means pattern, form, or shape. Unlike
the behaviourists, the Gestaltists believed that behaviour should be
studied as an organized pattern rather than as separate incidents of
stimulus and response. The familiar saying "The whole is greater than the
sum of its parts" expresses an important principle of the Gestalt
movement.
Gestalt psychology was founded about 1912 by Max Wertheimer, a German
psychologist. During the 1930's, Wertheimer and two colleagues took the
Gestalt movement to the United States.
Psychoanalysis was founded during the late 1800's and
early 1900's by the Austrian doctor Sigmund Freud. Psychoanalysis was
based on the theory that behaviour is determined by powerful inner forces,
most of which are buried in the unconscious mind. According to Freud and
other psychoanalysts, from early childhood people repress (force out of
conscious awareness) any desires or needs that are unacceptable to
themselves or to society. The repressed feelings can cause personality
disturbances, self-destructive behaviour, or even physical symptoms.
Freud developed several techniques to bring repressed feelings to the
level of conscious awareness. In a method called free association, the
patient relaxes and talks about anything that comes to mind while the
therapist listens for clues to the person's inner feelings. Psychoanalysts
also try to interpret dreams, which they regard as a reflection of
unconscious drives and conflicts. The goal is to help the patient
understand and accept repressed feelings and find ways to deal with them.
Modern psychology has incorporated many teachings of the earlier schools.
For example, though many psychologists disagree with certain of Freud's
ideas, most accept his concept that the unconscious plays a major role in
shaping behaviour. Similarly, most psychologists agree with the
behaviourists that environment influences behaviour and that they should
study chiefly observable actions. However, many psychologists object to
pure behaviourism. They believe that it pays too little attention to such
processes as reasoning and personality development. |

Psychology today has continued to develop in several directions. A group
of extreme behaviourists called the stimulus-response school
believe all behaviour is a series of responses to different stimuli.
According to these psychologists, the stimulus connected with any response
can eventually be identified. As a result, stimulus-response psychologists
regard behaviour as predictable and potentially controllable.
Another group of psychologists, who are known as the cognitive school,
believe there is more to human nature than a series of stimulus-response
connections. These psychologists concentrate on such mental processes as
thinking, reasoning, and self-awareness. They investigate how a person
gathers information about the world, processes the information, and plans
responses.
A school called humanistic psychology developed as an alternative
to behaviourism and psychoanalysis. Humanistic psychologists believe
individuals are controlled by their own values and choices and not
entirely by the environment, as behaviourists think, or by unconscious
drives, as psychoanalysts believe. The goal of humanistic psychology is to
help people function effectively and fulfil their own unique potential.
The supporters of this approach include the American psychologists Abraham
H. Maslow and Carl R. Rogers.
Many psychologists do not associate themselves with a particular school or
theory. Instead, they select and use what seems best from a wide variety
of sources. This approach is called eclecticism.
