Unit 1: History and Approaches
1.1: Introduction to Psychology
and Its Purposes
WHAT IS PSYCHOLOGY?
Word derives from the following:
▪ Greek: Psyche + Logos
Modern definition:
▪ The scientific study of behavior and mental processes
▪ Overt—easily seen; not hidden
▪ Covert—hidden
WHY IS PSYCHOLOGY CONSIDERED A SCIENCE?
Science studies observable phenomena
▪ Behavior is observable
▪ Applies the scientific method
Psychologists prefer scientific observation
▪ Based on empirical evidence
▪ Systematically gathered
▪ Intersubjective
Psychologists make data-driven decisions
▪ Treatments based on empirical evidence
▪ Intuition is not always correct in explaining behavior
PSYCHOLOGY’S FOUR GOALS
Describe
▪ Most basic goal
▪ First step in research psychology
▪ Requires precise use of language and definitions
Explain
▪ Provides reasons for behavior
▪ Involves a theory
Prediction
▪ Predicting behavior indicates we understand it to some degree (classical conditioning)
▪ Suggests how a set of conditions might influence behavior
▪ Control
▪ Can be used to provide treatment (e.g., behavioral therapy, medications, etc.)
▪ Shows we understand the underlying mechanisms of behavior
1.2: The Early Years and Today
A BRIEF HISTORY OF PSYCHOLOGY: BEGINNINGS
Wilhelm Wundt
▪ Considered the “Father of
Psychology”
▪ 1879: Established lab in Leipzig,
Germany
▪ Studied conscious experience:
reactions to various stimuli
▪ Used introspection
A BRIEF HISTORY OF PSYCHOLOGY: STRUCTURALISM
Edward Titchener
▪ Brought Wundt’s ideas to the U.S.
▪ Renamed ideas structuralism
▪ Tried to analyze “structure” of mental
life
▪ Like Wundt, used introspection
A BRIEF HISTORY OF PSYCHOLOGY: STRUCTURALISM
Introspection proved to be a poor methodology
▪ Structuralists frequently disagreed over observations
▪ No objective way to settle disagreements
▪ Introspection still useful in some studies (e.g., hypnosis,
meditation, problem solving, moods).
A BRIEF HISTORY OF PSYCHOLOGY: FUNCTIONALISM
William James
▪ Broadened psychology’s scope
▪ Inspired by Darwin and natural
selection theory
▪ Studied how the mind functions
to help us adapt
▪ Applied the term functionalism
A BRIEF HISTORY OF PSYCHOLOGY:
BEHAVIORISM
John Watson
▪ Deemed introspection as
unscientific
▪ Objected to study of the
“mind”
▪ Psychology must study
observable behavior
objectively
▪ Adopted Ivan Pavlov’s
concept of conditioning
▪ Observed relationship
between stimuli and
response
A BRIEF HISTORY OF PSYCHOLOGY:
RADICAL BEHAVIORISM
B.F. Skinner
▪ Believed mental events were
unnecessary to study behavior
▪ Studied relationship between
actions, rewards, and punishments
▪ Emphasized positive reinforcement
vs. punishment
▪ Worked with animals
A BRIEF HISTORY OF PSYCHOLOGY:
GESTALT
Max Wertheimer
▪ Mistake to analyze
psychological events in pieces;
many experiences cannot be
broken into smaller units
▪ “The whole is greater than
the sum of its parts.”
▪ Influenced perception,
personality
A BRIEF HISTORY OF PSYCHOLOGY:
PSYCHOANALYTIC PSYCHOLOGY
Sigmund Freud
▪ Behavior is largely influenced
by unconscious wishes,
thoughts, and desires;
especially sex and aggression
A BRIEF HISTORY OF PSYCHOLOGY:
PSYCHOANALYTIC PSYCHOLOGY
Sigmund Freud
▪ Repressed thoughts are revealed in dreams, emotions, and
slips of the tongue
▪ First to appreciate that childhood affects personality
▪ Created psychoanalysis, the first psychotherapy or “talking
cure”
▪ All thoughts and actions are determined; nothing is an accident
A BRIEF HISTORY OF PSYCHOLOGY:
HUMANISM
Carl Rogers, Abraham Maslow
▪ Rejected Freudian focus on unconscious
▪ Uncomfortable with behaviorists’ focus on conditioning
▪ Studied unique aspects of the person
▪ focus on subjective human experience.
▪ Each person has innate goodness and is able to make free
choices (contrast with Skinner and Freud’s determinism).
A BRIEF HISTORY OF PSYCHOLOGY:
HUMANISM
Abraham Maslow
▪ Studied those with exceptional mental health
▪ Emphasized self-actualization
▪ Making use of talents and abilities
▪ Maximizing full potential
A BRIEF HISTORY OF PSYCHOLOGY:
MODERN HUMANISM
Seek to understand how humans perceive ourselves and experience the world
Concerned with:
▪ Self image
▪ Self-evaluation
▪ Frame of reference
A BRIEF HISTORY OF PSYCHOLOGY:
THE ROLE OF DIVERSITY
Women and ethnic minorities
have made notable
contributions:
▪ Margaret Washburn
▪ 1894, awarded first Ph.D.
▪ 1906, published The Animal
Mind
A BRIEF HISTORY OF PSYCHOLOGY:
THE ROLE OF DIVERSITY
Women and ethnic minorities
have made notable
contributions:
▪ Francis Cecil Sumner
▪ 1920, first African American to
earn psychology degree
A BRIEF HISTORY OF PSYCHOLOGY:
THE ROLE OF DIVERSITY
Women and ethnic minorities
have made notable
contributions:
▪ Inez Beverly Prosser
▪ 1933, first African American
female to receive Ph.D.
HISTORY OF PSYCHOLOGY TIMELINE
PSYCHOLOGY TODAY: THREE PERSPECTIVES
Biological
▪ Behavior can be explained through internal physical, chemical,
and biological principles
▪ Uses brain scans to gather data (CT, MRI, PET)
▪ Includes evolutionary psychology and study of genetics
PSYCHOLOGY TODAY: THREE PERSPECTIVES
Cognitive or Psychological
▪ Behavior results from psychological processes
▪ Includes cognitive psychology and consciousness
▪ Incorporates psychodynamic and humanistic views
▪ Positive Psychology
▪ Study of human strengths, virtues, and optimal behavior
PSYCHOLOGY TODAY: THREE PERSPECTIVES
Sociocultural
▪ Many thoughts and behaviors are influenced by one’s culture
▪ Psychologists need to be aware of the impact cultural diversity
may have on our behaviors
▪ What is acceptable in one culture might be unacceptable in
another
▪ Cultural Relativity
▪ Social Norms

1.3: History of Psychology
Strengths and Weaknesses
Biopsychological View
Strengths
• It is very scientific.
• Experiments used are
measurable, objective, and
can be repeated to test for
reliability.
• Researchers have more
control over the variables.
• It is deterministic.
• It increases the likelihood of
being able to treat people with
abnormal behavior and
provides explanations about
the causes of behavior.
Weaknesses
• It focuses too much on the
“nature” side of the
nature/nurture debate.
• It is nomothetic.
• It develops theories about
disorders and generalizes
them to apply to everyone.
• It does not take into
account the view that
humans are unique.
Cognitive View
Strengths
• It looks at thought processes,
which were ignored by other
psychologists, especially
behaviorists
• Cognitive theories have been
applied to cognitive therapies
such as Rational Emotive
Therapy. This therapy has
been successful in changing
irrational thoughts into
rational thoughts so that
behavior improves.
Weaknesses
• It is reductionist.
• It is too mechanical; it
compares humans to
computers in that they have
similar processes.
Behavioristic View
Strengths
• It has successfully applied
classical and operant
conditioning.
• Systematic desensitization
is based on classical
conditioning and is useful
for treating phobias.
• It uses scientific methods of
research.
Weaknesses
• It focuses too much on the
“nurture” side of the
nature/nurture debate.
Sociocultural View
Strengths
• Cognitive development is a
social process. This
approach has demonstrated
the strong effect of social
influences on people’s
behavior.
Weaknesses
• The sociocultural view is
reductionist.
• It fails to acknowledge the
role of individual
differences within a social
setting.
• It has been argued that
some research has been
unethical.
Psychodynamic View
Strengths
• It takes both nature and
nurture into account
• It focuses on the effects
that childhood experiences
have on the developing
personality.
• It also led to other
psychologists to develop
theories on childhood.
Weaknesses
• It is unfalsifiable;
assumptions cannot be
scientifically measured or
proved wrong.
• It is deterministic; it
suggests that behavior is
pre-determined and that
people do not have free
will.
