This document provides an overview of the field of psychology. It discusses that psychology is the scientific study of behavior and mental processes. Some key topics covered include the various approaches in the history of psychology such as structuralism, functionalism, psychoanalytic, behavioral, cognitive; major figures that contributed to each approach like Wundt, James, Freud, Pavlov, Piaget; the goals of psychology including description, explanation, prediction, and influence; and the many subfields that modern psychology is divided into such as clinical, developmental, industrial/organizational, and forensic psychology.
3. Psychologists Point of View
They study complex behavior
• Physiological- having to do with an
organism’s physical processes
• Cognitive- having to do with an organism’s
thinking and understanding
4. What is Psychology?
• Is the scientific study of behavior that is
tested through scientific research
– the study can involve both animal and human
behaviors
– Some believe our thoughts, feelings, and
fantasies are important, but not always
observable
– the study of behavior must be systematic
5. Use of Systematic Method
• Usually asks and answers questions about
why people think, act, and feel as they do
reduces the chances of coming to false
conclusions
• Blind man and elephant story
6. The Goals of Psychology
• Description
• Explanation
• Prediction
• Influence
7. Description
• Describe or gather information about the
behavior being studied and present what
is known
8. Explanation
• Are not content with the facts
• They seek to explain why people or
animals behave
• Hypothesis- an assumption or prediction
about behavior that is tested through
scientific research
• Theory- a set of assumptions used to
explain phenomena and offered for
scientific study
9. Prediction
• Use knowledge and predict what
organisms think and feel in various
situations
• By studying past behaviors, psychologists
can predict future behaviors
10. Influence
• Psychologists seek to influence behavior
in helpful ways
• Basic Science- the pursuit of knowledge
about natural phenomena for its own sake
• Applied Science- discovering ways to use
scientific findings to accomplish practical
goals
12. Wilhelm Wundt
• Set up the first psychology lab in Leipzig,
Germany
• Two types of element: sensations and
feelings
• Believes an individual observes, analyzes,
and reports his or her mental experiences
14. Marmaduke Sampson
• Studied “why crime occurs”
• Believed behavior was the result of the
shape of the head

bumps on a person’s skull to determine
that person’s intellect and character traits
• Inspired scientists to consider the brain
instead of the heart as responsible for
human behavior
15. The Origins of Psychology
• 5th
and 6th
Centuries
– Greeks studied human behavior and decided
people were rational and not dominated by
gods
– Greeks set the stage for the development of
sciences
16. The Origins of Psychology
• 1500 and 1600s
– Copernicus- published idea that the earth was
not the center of the universe, the sun was.
– Galileo Galilei- used a telescope to confirm
the predictions of Copernicus
– Descartes- proposed a link between the body
and mind
17. Historical Approaches
• Structuralism
– Wilhelm Wundt- is acknowledged for
establishing modern psychology as a

– Structuralist- a psychologist who studied the
basic elements that make up conscious
mental experiences

which participants report their thoughts and
feelings
18. Functionalism
• William James- taught the first class in
Psychology at Harvard University
– Wrote the first textbook “The Principles of
Psychology”

the function instead of the structure of
consciousness
19. Inheritable Traits
• Sir Francis Galton
– Wanted to understand how heredity
influences a person’s abilities, character, and
behavior.
– His study focused on genius being a
hereditary trait
– Did not consider that distinguished families
may also have exceptional environments and
socioeconomic advantages
20. Inheritable Traits
• Scientists recognized flaws in Galton’s
research
• They came up with the theory that “a
person’s heredity and environment interact
to influence intelligence”
21. Gestalt Psychology
• German Psychologists
– Max Wertheimer
– Wolfgang Kohler
– Kurt Koffka
• Disagreed with the principles of structuralism
and behaviorism
• Believed perception was more than a sum of its
parts

perceptual experiences
23. Psychoanalytic Psychology

simple response to a stimulus
29. Biological Psychology
• Known today as behavioral neuroscience
• Psychobiologist- a psychologist who
studies how physical and chemical
changes in our bodies influence our
behavior
– Have found that genetic factors influence our
behaviors
