Psychology’s Roots
Prescientific Psychology Is the mind connected
to the body or distinct? Are ideas inborn or is
the mind a blank slate filled by experience?

Psychology’s Roots Prescientific Psychology
Philosophy Greek - Roman conceptualization of human experience
as contemporary history-making, a philosophy of the moral life a “reason to excel” (David McCullough, C-SPAN interview, 8-7-05)
Empiricism knowledge comes from experience via the senses science flourishes through observation and experiment psychological science refutes three theories of human
nature (Pinker, 2005): Locke’s “blank slate,” Rousseau’s “noble savage,” and Descarte’s “ghost in the machine”
Psychology’s Roots
Wilhelm Wundt opened the first psychology laboratory at the University of Leipzig (c. 1879)
Structure vs. Function
Structuralism Analyze consciousness
into basic elements
IntrospectionSystematic, self-observation in response to tones, optical illusions, fruit…
Sensation & Perception
Functionalism Investigate purpose of
consciousness, not structure
Stream of consciousnessConsciousness is a continuous flow of thoughts, not static
Mental testing, development, education, individual differences
Psychology’s Roots
Structuralism used introspection (looking in) to explore the elemental structure of the human mind
Psychology’s Roots
Functionalism focused on how behavioral processes function - how they enable organism to adapt, survive, and flourish
Academic vs. Popular Psychology; Historical overview of Psychology & the teaching of Introductory Psychology (some guiding anecdotes)
Psychology’s Roots
Myers’ Definition of Psychology The science of behavior (what we do) and
mental processes (sensations, perceptions, dreams, thoughts, beliefs, and feelings)
Psychology’s Big Question
Nature versus Nurture
The controversy over the relative contributions of biology and experience.
Nurture works on what nature endows.
Psychology’s Three Main Levels of Analysis
Contemporary Psychology
Psychology’s Subfields: Research
Psychologist What she does
BiologicalExplore the links between brain and mind.
DevelopmentalStudy changing abilities from womb to tomb.
CognitiveStudy how we perceive, think, and solve problems.
Personality Investigate our persistent traits.
SocialExplore how we view and affect one another.
Psychology’s Subfields: Research
Data: APA 1997
Psychology’s Subfields: Applied
Psychologist What she does
ClinicalStudies, assesses, and treats people with psychological disorders
CounselingHelps people cope with academic, vocational, and marital challenges.
EducationalStudies and helps individuals in school and educational settings
Industrial/Organizational
Studies and advises on behavior in the workplace.
Psychology’s Subfields: Applied
Data: APA 1997
A clinical psychologist (Ph.D.) studies, assesses, and treats troubled people with
psychotherapy.
Psychiatrists on the other hand are medical professionals (M.D.) who use treatments
like drugs and psychotherapy to treat psychologically diseased patients.
Clinical Psychology vs. Psychiatry
Why Do Psychology?
1. How can we differentiate between uniformed opinions and examined conclusions?
2. The science of psychology helps make these examined conclusions, which leads to our understanding of how people feel, think, and act as they do!
What About Intuition & Common Sense?
Many people believe that intuition and common sense are enough to bring forth
answers regarding human nature.
Intuition and common sense may aid queries, but they are not free of error.
Limits of Intuition
Personal interviewers may rely too much on their “gut
feelings” when meeting with job applicants.

Hindsight Bias is the “I-knew-it-all-along” phenomenon.
After learning the outcome of an event, many people believe they could have predicted that very outcome. We only knew the dot.com stocks would
plummet after they actually did plummet.
Hindsight Bias
Overconfidence
Sometimes we think we know more than we actually know.

these anagrams?
People said it would take about 10 seconds, yet on
average they took about 3 minutes (Goranson, 1978).
The Scientific Attitude
The scientific attitude is composed of curiosity (passion for exploration), skepticism
(doubting and questioning) and humility (ability to accept responsibility when wrong).
The Scientific Attitude
Critical Thinking thinking that does not
blindly accept arguments and conclusions examines assumptions discerns hidden values evaluates evidence assesses conclusions
The Amazing Randi--Skeptic
Science or Pseudo-science?
How Do Psychologists Ask & Answer Questions?
Psychologists, like all scientists, use the scientific method to construct
theories that organize, summarize and simplify observations.
The Scientific Method
Theory an explanation using an integrated set of
principles that organizes and predicts observations
Hypothesis a testable prediction often implied by a theory
Research Process
The Scientific Method
Operational Definition a statement of procedures (operations)
used to define research variables example-
intelligence may be operationally defined as what an intelligence test measures
The Scientific Method
Replication repeating the essence of a research
study to see whether the basic finding extends to other participants and circumstances
usually with different participants in different situations
Description
Psychologists describe behavior using case studies, surveys, and naturalistic observation
Description
Case Study observation
technique in which one person is studied in depth in the hope of revealing universal principals
Is language uniquely human?
Description
Survey technique for ascertaining the self-
reported attitudes or behaviors of people
usually by questioning a representative, random sample of people
Survey
Wording can change the results of a survey.
Q: Should cigarette ads and pornography be allowed on television? (not allowed vs. forbid)
Wording Effects
Description
Survey
Random Sampling
If each member of a population has an equal chance of inclusion into a sample, it is called a
random sample (unbiased). If the survey
sample is biased, its results are not valid.
The fastest way to know about the marble color ratio is to blindly transfer a few into a smaller jar and count them.
Description
Naturalistic Observation observing and
recording behavior in naturally occurring situations without trying to manipulate and control the situation
Descriptive Methods
Case studies, surveys, and naturalistic observation describe
behaviors.
Summary
Correlation
Correlation Coefficient a statistical measure of the extent to which
two factors vary together, and thus how well either factor predicts the other
Correlation coefficient
Indicates directionof relationship
(positive or negative)
Indicates strengthof relationship(0.00 to 1.00)
r = +.37

Illusory Correlation
Illusory Correlation the
perception of a relationship where none exists (Gilovich, 1991, Myers’ text p. 20)

Idea Generation (adapted from Niederhoffer, 1-28-04, “Research Methods”)
Personal Living Spaces (PLS) are rich with information about personality, values, abilities, and lifestyle
H1: People’s dispositions are revealed in their behavioral residues
H2: Observers use information in PLS to form impressions about people
Personality** I see myself as someone who is…
Extraverted Outgoing, animated, sociable, assertive
Agreeable Helpful, cooperative, pleasant
Conscientious Self-discipline, duty, order
Emotionally Stable Anxiety, depression, moodiness, vulnerability
Open to new experiences
Intellect, imagination, curiosity, creativity

Can observers accurately judge conscientiousness from living spaces?+1 = the more conscientious people said
they were, the more their rooms were rated as conscientious.
-1 = the more conscientious people said they were, the less their rooms were rated as conscientious.
0 = no relation at all
.81 --- yes, observers can accurately judge conscientiousness from living spaces
Given random data, we look for order and meaningful patterns.
Order in Random Events
Your chances of being dealt either of these hands is precisely the same: 1 in 2,598,960.
Order in Random Events
Given large numbers of random outcomes, a few are likely to express order.

Experimentation
Experiment an investigator manipulates one or more
factors (independent variables) to observe their effect on some behavior or mental process (the dependent variable)
by random assignment of participants the experiment controls other relevant factors
Experimentation Double-Blind Procedure
both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo
commonly used in drug-evaluation studies “Water, water everywhere”
Placebo an inert substance or condition that may be
administered instead of a presumed active agent, to see if it triggers the effects believed to characterize the active agent
Film
Experimentation
Experimental Condition the condition of an experiment that
exposes participants to the treatment, that is, to one version of the independent variable
Control Condition the condition of an experiment that
contrasts with the experimental treatment serves as a comparison for evaluating the
effect of the treatment
Experimentation
Random Assignment assigning participants to experimental
and control conditions by chance minimizes pre-existing differences
between those assigned to the different groups
Experimentation
Like other sciences, experimentation is the backbone of psychological research.
Experiments isolate causes and their effects.
Exploring Cause and Effect
Many factors influence our behavior. Experiments (1) manipulate factors that interest us, while other factors are kept
under (2) control.
Effects generated by manipulated factors isolate cause and effect relationships.
Exploring Cause & Effect
In evaluating drug therapies, patients and experimenter’s assistants should
remain unaware of which patients had the real treatment and which patients
had the placebo treatment.
Evaluating Therapies
Double-blind Procedure
Assigning participants to experimental (breast-fed) and control (formula-fed) conditions by random assignment minimizes pre-existing
differences between the two groups.
Evaluating Therapies
Random Assignment
An independent variable is a factor manipulated by the experimenter. The effect of the independent
variable is the focus of the study. For example, when examining the effects of breast
feeding upon intelligence, breast feeding is the independent variable.
Independent Variable
A dependent variable is a factor that may change in response to an independent variable. In psychology, it is usually a
behavior or a mental process.
For example, in our study on the effect of breast feeding upon intelligence,
intelligence is the dependent variable.

FAQ
Q1. Can laboratory experiments illuminate everyday life?
Ans: Artificial laboratory conditions are created to study behavior in simplistic terms. The goal is to find underlying principles that govern behavior.
FAQ
Q2. Does behavior depend on one’s culture and gender?
Ans: Even when specific attitudes and behaviors vary across cultures, as they often do, the underlying processes are much
the same. Biology determines our sex, and culture further bends the genders. However, in many ways woman and man
are similarly human.

FAQ
Q3. Why do psychologists study animals, and is it ethical to experiment on animals?
Ans: Studying animals gives us the understanding of many behaviors that may have common biology across animals and
humans. From animal studies, we have gained insights to devastating and fatal diseases. All researchers who deal with animal research are required to follow ethical guidelines in
caring for these animals.

FAQ
Q4. Is it ethical to experiment on people?
Ans: Yes. Experiments that do not involve any kind of physical or psychological harm beyond normal levels encountered in daily
life may be carried out.
FAQ
Q5. Is psychology free of value judgments?
Ans: No. Psychology emerges from people who subscribe to a set of values and judgments.
