Prologue: Psychology’s Roots
Prescientific Psychology Is the mind connected to the body
or distinct? Aristotle (heart) Plato (head)
Are ideas inborn or is the mind a blank slate filled by experience?
Are we controlled by natural elements or supernatural elements?

Prologue: Contemporary Psychology
John Lockeempiricist; believed that knowledge is acquired solely through life experiences. Tabula Rasa: blank tabletClaimed each of us is born a blank slate on which are written the life experiences we acquire through our senses.(Plato believed just the opposite)
Prologue: Contemporary Psychology
Rene Descartesrationalist; insisted we should doubt everything that is not proved by our own reasoning. True knowledge comes through correct reasoning and it is inborn.
Prologue: Psychology’s Roots
Psychological Science Is BornEmpiricism
Knowledge comes from experience via the senses
Science flourishes through observation and experiment
Wilhelm Wundt
Wundt is referred to as the “father of psychology” because in 1879 he started the first laboratory in psychology for studying humans.
He broke into parts the elements of feelings and thought.
Using a procedure called “introspection” he introduced scientific procedure to study feelings.
Prologue: Psychology’s Roots
Structuralism used introspection (looking in) to explore the elemental structures or “atoms” of the human mind
Other PioneersG. Stanley Hall (1844-1924)
Wundt’s student, brought lab to USA at John’s Hopkins University
Edward Titchener (1867–1927) Wundt’s student, professor at Cornell University
William James (1842–1910) started psychology at Harvard in 1870s opposed Wundt and Titchener’s approach functionalism – influenced by Darwin to focus on
how behaviors help us adapt to the environment
Sigmund Freud (1856–1939) Austrian physician that focused on illness psychoanalytic theory of mental disorders
E. B. Titchener (1867–1927)
William James
In 1890, he published Principles of Psychology. The book was 1400 pages long, two volumes in length and it took him 12 years to write.
Unlike Wundt, he did not want to break behavior into parts; instead, he never wanted to lose sight of the individual as a whole. His goal was to uncover the “functions” of the mind …FUNCTIONALISM
James is considered to be one of the founders of American psychology.
Prologue: Psychology’s Roots
Functionalism focused on how behavioral processes function- how they enable organism to adapt, survive, and flourish
Other PioneersJohn B. Watson (1878–1958)
psychologists should study overt behavior
Adapted Pavlovian learning theory to humans
B. F. Skinner (1904–1990) American psychologist at Harvard studied learning and effect of
reinforcement behaviorism
John B. Watson (1878–1958)
B. F. Skinner (1904–1990)

physiologist James--American philosopher Pavlov--Russian physiologist Freud--Austrian physician Piaget--Swiss biologist Wortheimer, Kohler, Koffka –

Psychology’s Big IssuesStability vs. Change
Do our individual traits persist as we age?
Do we become older versions of ourselves?
Prologue: Contemporary Psychology
Rationality vs. Irrationality Rationality– reasonableness, good sense
of equity and proportion Irrationality– not reasonable in thinking
or behaving, distorted perception of reality
Philosophical Developments Another Question:
Nature vs. Nurture
the relative contribution that genes and experience make to development of psychological traits and behaviors
Are abilities determined by our genes or our experiences?
What are the interactions between genetics and environment?
What effect does it have on behavior?
Prologue: Contemporary Psychology
Psychology’s Perspectives
Approaches to Psychology
Biological
Behavioral
Psychoanalytic
Humanistic
Cognitive
Sociocultural
A. Biological/Neuroscience Perspective
Study the physiological mechanisms in the brain and nervous system that organize and control behavior
Focus may be at various levels individual neurons areas of the brain specific functions like eating, emotion, or learning
Interest in behavior distinguishes biological psychology from many other biological sciences
B. Evolutionary Perspective
Influenced by Darwin and the emphasis on innate, adaptive behavior patterns
Application of principles of evolution to explain behavior and psychological processes
On the Origin of Species was published in 1859. His theory was that humans and animals had evolved and changed. His theory inspired scientists to study animals in order to understand human behavior.
Charles Darwin
Prologue: Contemporary Psychology
Natural selection principle that
those inherited trait variations contributing to survival will most likely be passed on to succeeding generations
Charles Darwin
C. Behavior-Genetics Perspective
Influenced by Nature vs. Nurture Debate
How do our genes influence behavior and how does our environment influence our mental processes?
John B. Watson
Watson studied the impact of learning on people. This led to the school of behaviorism.
He believed that careful and structured parenting could eliminate psychological problems.
Watson later wrote a book applying scientific methods to raising children.
The Behavioral Approach
This approach emphasizes that behavior is primarily the result of learning and not due to a person’s thoughts and unconscious processes.
People such as B. F. Skinner (pictured to the left) and John B. Watson are called behaviorists.
D. Behavioral Perspective
View of behavior based on experience or learning
Classical conditioning Operant conditioning
E. Cognitive PerspectiveHow is knowledge acquired,
organized, remembered, and used to guide behavior?
Influences include Wortheimer, Kohler, Koffka – Gestalt
Find the “whole pattern” of our perceptions
Piaget – studied intellectual development Chomsky – studied language Cybernetics – science of information
processing
F. The Sociocultural ApproachThis approach looks at the impact that society, culture, ethnicity, race, and religion have on personality.
Psychoanalytic Cognitive
Cross-Cultural Perspective
The study of psychological differences among people living in different cultural groups
How are people’s thoughts, feelings and behavior influenced by their culture?
What are the common elements across culture? Are these innate?
Sigmund Freud
Freud developed the first comprehensive theory of human development and behavior, especially how the personality develops.
He believed that childhood memories and thoughts influenced the behavior of people when they became adults.
G. Psychodynamic Perspective
View of behavior based on experience treating patients
Psychoanalytic approach (Sigmund Freud) both a method of treatment and a theory of the
mind behavior reflects combinations of conscious and
unconscious influences drives and urges within the unconscious
component of mind influence thought and behavior early childhood experiences shape unconscious
motivations
H. Humanistic Perspective
Developed by Abraham Maslow & Carl Rogers
behavior reflects innate ‘actualization’ focus on conscious forces and self
perception more positive view of basic forces than
Freud’s
The Humanistic Approach
Carl Rogers is the best known of the humanists.
This approach emphasizes that people have free will, self-concepts and are basically good. Humanists believe that every person can fulfill his or her potential.
Carl Rogers (1902–1987) Abraham Maslow (1908–1970)
Psychology should study how behavior and mental processes allow organisms to adapt to their environments
School/Approach Evolutionary perspective
Founder Charles Darwin
Psychology should emphasize people’s unique potential for psychological growth
School/Approach Humanistic
Founder Maslow
Psychology should only study observable behavior?
School/Approach Behaviorism
Founder Watson/Skinner
Which Perspective?
Which Perspective?
Emily is anxious because of
a hormonal imbalance. Once the doctors prescribe the right medicine, she feels “normal” again.
Which Perspective?
Samantha won’t acknowledge that she has an addiction. She’d rather lie to herself than admit the truth. Even though she wants to quit, she keeps going back to the same old habits. Each time she finds herself giving in to her urges and using, she finds a way to “forget” it ever happened so she doesn’t feel guilty.
Which Perspective?
Betty is a naughty child because her parents never give her consequences and they always give in to her demands. She often throws tantrums and acts out at the grocery store because she knows they will buy her treats to keep her quiet. They are training her to have a “naughty” personality.
Which Perspective?
Bob is depressed because he keeps thinking self-defeating thoughts. He never looks at the bright side of things. Once he gets into a negative mood, his thoughts spiral him down emotionally into a state of depression.
Which Perspective?
Fernando would like to be on the varsity team before he graduates. He sets a goal to works every day throughout the off season to get better. However, his parents didn’t think it is worth his time. They make him get a summer job. When tryouts arrive, he is not selected for the team. He feels defeated and his self-esteem suffers, causing him to perform poorly in school.
Which Perspective?
Roger spent his entire childhood in a rough neighborhood. He learned that fighting is part of life. When he moved to a new neighborhood his junior year, his parents were embarrassed by the number of times he got suspended for fighting. If only the administration knew where he’s really coming from….
