Psychological Science is Born
Sigmund Freud, and his followers emphasized the importance of the unconscious mind and
its effects on human behavior. His views became the basis for the psychodynamic
perspective in psychology.

Psychology Today
We define psychology today as the scientific study of behavior (what we do) and mental processes (inner thoughts and feelings).
We use science- observation and evaluation, to draw conclusions about behavior and mental processing.
![Page 7: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/7.jpg)
Psychology’s Current Perspectives
Perspective Focus Sample QuestionsNeuroscience How the body and
brain enables emotions?
How are messages transmitted in the body? How is blood chemistry linked with moods and motives?
Evolutionary How the natural selection of traits the promotes the perpetuation of one’s genes?
How does evolution influence behavior tendencies?
Behavior genetics
How much our genes and our environments influence our individual differences?
To what extent are psychological traits such as intelligence, personality, sexual orientation, and vulnerability to depression attributable to our genes? To our environment?
![Page 8: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/8.jpg)
Psychology’s Current Perspectives
Perspective Focus Sample Questions
Psychodynamic
How behavior springs from unconscious drives and conflicts?
How can someone’s personality traits and disorders be explained in terms of sexual and aggressive drives or as disguised effects of unfulfilled wishes and childhood traumas?
Behavioral How we learn observable responses?
How do we learn to fear particular objects or situations? What is the most effective way to alter our behavior, say to lose weight or quit smoking?
![Page 9: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/9.jpg)
Psychology’s Current Perspectives
Perspective Focus Sample QuestionsCognitive How we encode,
process, store and retrieve information?
How do we use information in remembering? Reasoning? Problem solving?
Social-cultural
How behavior and thinking vary across situations and cultures?
How are we — as Africans, Asians, Australians or North Americans – alike as members of human family? As products of different environmental contexts, how do we differ?
![Page 10: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/10.jpg)
Four Big Ideas in Psychology
1. Critical Thinking is Smart Thinking2. Behavior is a Biopsychosocial Event3. We Operate with a Two-Track Mind
(Dual Processing)
4. Psychology Explores Human Strengths as Well as Challenges
![Page 11: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/11.jpg)
Critical ThinkingCritical thinking does not accept arguments and conclusions blindly.
It examines assumptions, discerns hidden values, evaluates evidence and assesses conclusions.
“4 out of 5 students prefer Miss King as their social studies teacher.”
Ask, who did they survey? Who were the students polled? How was the question worded? All of these will change the results of the survey!
![Page 12: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/12.jpg)
Psychology’s Three Main Levels of Analysis
![Page 13: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/13.jpg)
Nature vs. Nurture
• Controversy over the relative contributions that genes (nature) and experience (nurture) make to the development of psychological traits and behavior
• Nurture works on what nature endows
![Page 14: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/14.jpg)
The Two-Track Mind
• Dual Processing- information is processed on two levels; conscious and the unconscious (information that is processed without awareness)– Visual Perception- recognize things and
future actions– Visual Action- guides our moment to
moment actions
![Page 15: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/15.jpg)

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!
![Page 21: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/21.jpg)
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 help answer questions, but they are not free of error.
Why are the answers reached by thinking critically more reliable than ordinary common sense?
![Page 22: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/22.jpg)
Limits of Intuition
Personal interviewers may rely too much on their “gut feelings” when
meeting with job applicants.
![Page 23: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/23.jpg)
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 housing market would plummet ONLY after it actually did plummet.
•“Anything seems commonplace, once explained.” Dr. Watson to Sherlock Holmes.•Two phenomena – hindsight bias and judgmental overconfidence – illustrate why we cannot rely solely on intuition and common sense.
Hindsight Bias

Overconfidence
Sometimes we think we know more than we actually know.

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).
![Page 27: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/27.jpg)
Scientific Method in Psychology
Psychologists, like all scientists, use the scientific method to construct
theories that organize, summarize and simplify observations.
![Page 28: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/28.jpg)
A theory is an explanation that integrates principles and organizes
and predicts behavior or events.
For example, low self-esteem contributes to depression.
Theory
![Page 29: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/29.jpg)
A hypothesis is a testable prediction, often prompted by a theory, to enable
us to accept, reject or revise the theory.
People with low self-esteem are apt to feel more depressed.
Hypothesis
![Page 30: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/30.jpg)
Research would require us to administer tests of self-esteem and
depression. Individuals who score low on a self-esteem test and high on a depression test would confirm our
hypothesis.

Operational Definitions
• A statement of procedures used to define research variables
• Leads to Replication- repeating of research to see if the findings were accurate

Description
Case Study
A technique in which one person, or small group of people, is studied in depth to reveal underlying behavioral principles.
Is language uniquely human?

Case Study
• Suggest directions for further study• Show us what can happen
• Individual cases may mislead us because they are atypical

Survey
A technique for ascertaining the self-reported attitudes, opinions or behaviors of people usually done by questioning a
representative, random sample of people.
![Page 36: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/36.jpg)
Survey

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.

Correlation
When one trait or behavior accompanies another, we say the two
correlate.
Correlation coefficient
Indicates directionof relationship
(positive or negative)
Indicates strengthof relationship(0.00 to 1.00)
r = 0.37+
Correlation Coefficient is a statistical measure of the relationship between two
variables.
![Page 41: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/41.jpg)
Correlation
• Positive Correlation- (0 and +1) direct relationship; two things increase and decrease together
• Negative Correlation- (0 and -1) indicates an inverse relationship, one thing increases the other decreases
• Zero Correlation- (around 0) weak relationship; little or no relationship

Illusory Correlation
The perception of a relationship where no relationship actually exists. Parents conceive
children after adoption.
Ex. Length of Marriage and Hair Loss

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
Like other sciences, experimentation is the backbone of psychological research.
Experiments isolate causes and their effects.
Exploring Cause and Effect
![Page 47: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/47.jpg)
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
![Page 48: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/48.jpg)
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.

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
![Page 51: Psychology in Everyday Life](https://reader035.vdocuments.mx/reader035/viewer/2022062304/56812c6c550346895d910384/html5/thumbnails/51.jpg)
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.
