Chapter 1: The Evolution of
Psychology
What is Psychology
Psychology is
– the science that studies behavior and
– the physiological and cognitive processes
that underlie it, and
– it is the profession that
– applies the knowledge to solve practical
problems.
How Psychology Developed
• Prior to 1879
– Physiology and philosophy –Parents of Psy.
• Wilhelm Wundt (1832-1920)
University of Leipzig, Germany
– Psychology an independent discipline
– Established the first laboratory for the study of
psychology in 1879
The Battle of the “Schools” in the U.S.:
Structuralism vs. Functionalism
Structuralism – Edward Titchener
– Analyze consciousness into basic elements
– Experimental Introspection –
• careful, systematic observations of one’s
own conscious experience
The Battle of the “Schools” in the U.S.:
Structuralism vs. Functionalism
Functionalism – William James
– Investigate function/purpose of consciousness
– Stream of Consciousness
– Led to investigation of mental testing,
developmental patterns, and sex differences
– G. Stanley Hall – Founder and1st APA President
Behaviorism: Redefining Psychology
John B. Watson (1878-1958): United States
– Behaviorism
• Psychology = scientific study of behavior
• Behavior = overt or observable responses or
activities
John Watson and the Nature-Nurture Debate
• Nurture, not nature (Heredity vs. Environment)
– “give me a dozen healthy infants, wellformed, and my own special world to bring
them up in and I’ll guarantee to take any
one at random and train him to become any
type of specialist I might select – doctor,
lawyer, artist, merchant-chief, and yes, even
beggar-man and thief…”
Behaviorism: Redefining Psychology
• Radical reorientation of psychology as a science
of observable behavior
• Animals can be studied to understand humans
Are people free?
B.F. Skinner
B.F. Skinner (1904-1990): United States
– Responses that lead to positive outcomes
are repeated
– Responses that lead to negative outcomes
are not repeated
– Behavior is Lawful
Behaviorism Today
Albert Bandura (1925 - ): United States
– Cognitive Behaviorism (Neo Behaviorism)
– Cognitions and social situations influence
learning.
– Humans are active agents.
Sigmund Freud and the Concept of the
Unconscious Mind
Sigmund Freud (1856-1939): Austria
– Psychoanalytic school of thought
– Thought that Consciousness should not be
the focus of Psychology
– Emphasis on unconscious processes
influencing behavior
Freud’s Ideas: Controversy and Influence
• Unconscious exerts great influence on behavior;
behavior is not accidental
• Unconscious conflict related to sexuality plays a
central role in behavior
• Personality is developed in first 5 years
• Significant influence on the field of psychology
The 1950’s: Opposition to Psychoanalytic
Theory and Behaviorism
• Charges that both were de-humanizing
• A new school of thought emerged – Humanism
– Abraham Maslow (1908-1970) and
Carl Rogers (1902-1987)
– Emphasis on the unique qualities of humans:
freedom and personal growth
Putting the Psyche Back in Psychology:
The Return of Cognition
• Cognition = mental processes involved in
acquiring knowledge
• 1950’s and 60’s – Piaget, Chomsky, and
Simon
– Application of scientific methods to
studying internal mental events
Biological Psychology:
The Biological Basis of Behavior
Biological perspective - behavior explained in
terms of physiological processes –
Brain, biology and genetics
• Human Genome Project
• Pharmaceuticals
Evolutionary Psychology: Human Adaptations
• Natural selection occurs for behavioral, as well as
physical, characteristics
• Buss, Daly & Wilson, Cosmides & Tooby – 80’s
and 90’s
• Mating preferences, jealousy, aggression,
sexual behavior, language, decision making,
personality, and development
Positive Psychology
• Martin Seligman’s epiphany
• Humanist concerns revisited
• Uses theory and research to better
understand the positive, creative, and fulfilling
aspects of human existence
– Positive subjective experiences
– Positive individual traits
– Positive institutions and communities
