– Biological• Evolutionary
– Behaviorism– Cognitive
• Gestalt– Psychoanalytic/Psychodynamic– Humanism – Social
• Make comparisons• Highlight contrasting views
Outline
Approaches to Psychology Concept Map
What is Psychology?
• Psychology is the scientific study of behavior and mental processes
• Scientific? – Not just common sense or guesses – Psychology uses the scientific method – Scientific Method: careful observations and the
experimental testing of hypothesis• Behavior – what people do on the outside• Mental Processes – Thinking - we call this
cognition.• Psychology includes the study of both humans and
animals
Outline
Outline
What is Psychology?
• Psychology is the scientific study of behavior and mental processes
• It is the study of WHY.• Why do humans do the things they
do?• “Cause we crazy” • Please delete this word from your
everyday usage. It means nothing.

Psychology’s RootsPrescientific Psychology
• Ancient Greeks (450-300 BCE)– Socrates: knowledge is innate– Plato: “”– Aristotle: used observations;
knowledge not pre-existing (grows from experience)
Psychology’s RootsPrescientific Psychology
• Rene Descartes: early theories about nerves (way off)
• Francis Bacon: scientific approach; human desire to perceive patterns
• John Locke– Tabula Rasa (blank
(slate)• Led to Empiricism
Empiricism
= the view that knowledge originates in experience and that science should, therefore, rely on observation and experimentation.
Psychology’s RootsPsychological Science is Born
• Wilhelm Wundt (1879)– University of Leipzig– Father of Modern Psychology– Started the first psych lab
Psychology’s RootsThinking About the Mind’s Structure• Edward Titchener
– Structuralism•Introspection
– an early school of psychology that used introspectionto explore the structural elements of the
human mind.
Psychology’s RootsThinking About the Mind’s Function
• William James– Functionalism– Mary Calkins– Margaret Floy Washburn
• Experimental psychology– Explore behavior & thinking through experiments
Psychological Science Develops
• Sigmund Freud: how unconscious thought processes; emotional response to childhood behavior affect behavior
Psychological Science Develops
• Behaviorism– John B. Watson – B.F. Skinner– “scientific study of
observable behavior”– Science rooted in observation
Behaviorism
= the view that psychology (1) should be an objective science that (2) studies behavior without reference to mental processes.
• Most research psychologists today agree with (1) but not with (2).
Psychological Science Develops
• Humanistic psychology– Carl Rogers– Abraham Maslow
• Cognitive Neuroscience
current environmental influences can nurture or limit our growth potential; need for love and acceptance
Outline
More concerned about moving up
Contemporary Psychology
Psychology’s Biggest Question
• Nature – Nurture Issue– Biology versus experience– Charles Darwin
–Natural
selection
Natural Selection
= the principle that, among the range of inherited trait variations, those contributing to reproduction and survival will most likely be passed on to succeeding generations.
Psychology’s Three Main Levels of Analysis• Levels of Analysis: differing
complementary views for analyzing any given phenomenon.– Biological– Psychological– Social-cultural
• Biopsychosocial Approach
Psychology’s Three Main Levels of Analysis
What are approaches to psych?
BiologicalEvolutionaryBehaviorismCognitivePsychodynamicHumanism GestaltSocial
Approaches are lenses through which to explain human behavior
Outline
Biological Psychology (neuroscience)
• This approach to explaining human behavior and mental processes focuses on biological mechanisms and structures. It looks to such things as the brain, neurotransmitters, hormones, drugs (both legal and illegal), and genetics.
Outline
A Biological Approach looks for Biological Answers?
Approaches are lenses through which to explain human behavior

Biological Psychology is Observable
Evolutionary Psychology• Explains human behavior by looking at
what made us most likely to survive/reproduce– Language – How did communication make
us more likely to survive?– Altruism – Why are we nice to each other
if this is just about survival of the fittest?– Sexual attraction – Is there a reason
certain aspects of a person are considered ‘attractive’ Why not sexy elbows?
Outline
Why do we find blue eyes attractive?
Outline
If only . . . .
Behaviorism• This approach only studies observable
human BEHAVIOR. It focuses on how we:– LEARN (or are conditioned)– React to our environment
• Since you can not observe the mind, behaviorists see it as a BLACK BOX. Can’t see it? Don’t study it.
• Big names– Pavlov – Dogs – Watson – Little Albert– Skinner – Operant Conditioning
Outline
This is odd behavior, right?
Would you do it?
Reward
Avoid Punishment?
Cognitive Psychology
• School of psychology that studies mental processes– Thinking, feeling, remembering, making
decisions/judgments and language• Studies how we encode, process, store, and
retrieve information.• Studies behavior and makes inferences about the
mental processes behind the behavior• Thanks to new technologies like CAT scans, MRIs
and fMRIs, we can open the black box.
Outline
Gestalt Psychology
• Gestalt is a German word that means “the whole”
• This approach to psychology looks at how your perceptions of the word come together to form you whole perception.
• This perception is often greater than the sum of its parts.
Gestalt Psychology
Psychodynamic Psychology• Personality theory that says behavior
springs from unconscious drives and conflicts
• The Unconscious is a dynamic cauldron of primitive drives, forbidden desires and nameless fears. It drags us down.
• Psychoanalysis – patient lies on a couch and recounts dreams and conducts free association.
• Sigmund Freud
Outline
Social Psychology (socio-cultural)
• Study of how people influence one another• Topics include:
– First impressions– Interpersonal attraction– Attitude formation– Prejudice– Behavior in a group– Obedience to Authority
• Some Applications include:– Support groups– Family Therapy– Sensitivity Training
Outline
Conformity
Compare and Contrast
• Compare two approaches– For example, both the biological and behavioral
approaches deal with things that are directly observable making them the most scientific of the approaches
• Contrast two approaches– While psychoanalysis focuses on how the
unconscious causes problems for the individual, humanism focuses on how individuals can achieve their full potential.
Outline
Psychology’s Subfields
• Applied Research– Industrial/organizational psychology– Human factors psychology– Counseling psychology– Clinical psychology– Psychiatry
Applied Research
= scientific study that aims to solve practical problems.
Industrial-Organizational (I/O) Psychology
= the application of psychological concepts and methods to optimizing human behavior in workplaces.
Human Factors Psychology
= the study of how people and machines interact resulting in the design of machines and environments.
Counseling Psychology
= a branch of psychology that assists people with problems in living (often related to school, work, and marriage) and in achieving greater well-being.
Clinical Psychology
= a branch of psychology that studies, assesses, and treats people with psychological disorders.
Clinical Psychology
= a branch of psychology that studies, assesses, and treats people with psychological disorders.
Psychiatry
= a branch of medicine dealing with psychological disorders; practiced by physicians who often provide medical (for example, drug) treatments as well as psychological therapy.
