2. • Psychology: the scientific study of
behavior and mental processes
– Behavior: any action that others can observe
or measure.
• This includes almost everything that a person
could do. (walk, talk, sleep, eat, blink, etc.)
• Some things can‟t be seen. [Brain activity is
measured with an electroencephalograph (EEG)]
– Cognitive activities: private mental processes
known only to the individual. (Ex:
dreams, thoughts, memories)
– Psychological Constructs: What researchers
use to talk about cognitive activities. (how
they affect your behavior)
3. • Goal of Psychology:
– Psychologist seek to observe and describe
behavior which enables them to better predict
and control one‟s behavior.
• Very evident in the field of sports psychology
– They may use positive visualization. (picturing exactly
how it is supposed to look when the action is done
correctly)
4. • Psychology is a social science with some
foundations in the natural sciences.
– There are other social sciences: History,
Anthropology, Economics, Political Science,
Sociology
– All these other social sciences deal with individuals
and their behavior, which is the basis of Psychology.
• Psychology also has some base in the natural
sciences
– The Natural sciences include: Biology, Chemistry,
Physics.
– Psychologist study the functions of the brain which is
closely linked to Biology and Anatomy
5. • Psychologist will test their ideas through
research. There are two main research
methods: Survey and Experimentation.
– Some psychologist use animal experimentation to
explain human behavior. Other research can only be
conducted on humans.
• Psychologist organize their thoughts or ideas
into theories.
– Theory: a statement that attempts to explain why
things are the way they are or happen the way they
do.
– Principle: a basic truth or law that most Psychologist
will agree on.
• These theories are constantly updated or discarded. Ex: Is
the world flat?

13. • 16th, 17th, 18th centuries
– the start of the science of Phrenology- the
reading of the bumps on your head
• 1879 William Wundt
– Starts the field (or school) of psychology
called Structuralism
– It‟s basis is that your conscious is broken into
two basic elements
• Objective sensations
• Subjective feelings
– The mind functions by combining the these
two basic elements
14. • William James
– Founded the school of Functionalism
– Disagreed with Wundt and thought that an
experience is a “stream of consciousness”
– He wrote The Principles of Psychology in
1890 (considered to be the first text book on
psychology)
– Functionalist are concerned with how mental
processes help organisms adapt to their
environment
– Successful behaviors are repeated and
unsuccessful ones are dropped
15. • The difference between Functionalism and
Structuralism:
– Structuralism asks: what are the elements (or
structures) of the psychological process?
– Functionalism ask: What are the purposes (or
functions) of these behaviors and mental
processes?
– In other words “one asks what are the parts?
The other asks what do the parts do?”
16. • Sigmond Freud
– The father of Psychoanalysis

motives and internal conflicts in determining
human behavior
– Big into interpretation of slips and dreams

patients (not in a lab)
– He felt you are driven by your subconscious
mind
– His theories are sometimes called
psychodynamic thinking
17. • John B Watson
– Founder of Behaviorism
– Feels that it is unscientific to study
conscious, because it is impossible to tell
what others are thinking, especially animals
– He felt it more important to watch
observable, measurable events
– He defined Psychology as the scientific study
of observable behavior
18. • B.F. Skinner
– Known for his work in the field of
reinforcement.

receive information influences how they
interpret it
– They focus on the big picture rather then the
parts of the picture

modified to form more modern perspectives
• Biological Perspective:
– emphasizes the influence of biology on
behavior
– They look at how the different parts of your
brain control your behavior
• Evolutionary Perspective:
– They feel that behaviors, like other
evolutionary characteristics are passed down
to offspring
20. • Cognitive Perspective:
– Emphasizes the role played by thoughts in
determining behavior

and how it processes information
• Humanistic Perspective:
– Stresses the human capacity for self-
fulfillment.
– They believe you are in charge of your own
behavior

learned experiences
• The social learning theory suggest that you can
learn almost anything from watching others
experience it.
22. • Socio-cultural Prospective:
– Addresses issues such as
ethnicity, gender, culture, and socioeconomic
status on behavior
– Are some groups smarter than others?
– Are women smarter than men?
