Lecture Notes

o Are people telling the truth?

• True – deceiving research subject is sometimes considered ethical  o They only tell you what they want you to know

o Its for science

• Early schools of Psychology

o The Science of Psychology

▪ Wilhelm Wundt promotes the belief that experimental methods  should be used to study mental processes.

▪ “What is the best way to measure mental processes?”

o Structuralism

▪ Edward Titchener, a student of Wundt, held that complex  

conscious experiences could be broken down into elemental parts  or structures

o Functionalism  

▪ Advocated by William James and influenced by Darwin,  

functionalism focuses on how behaviors function to allow people  and animals to adapt to their environment

▪ “What are the structures of conscious experiences?”

• What are the functions of behavior and mental experiences?

o Why did you do that?

• How can psychology be applied to life?

o First Major Psychological Schools: William James’s Students ▪ G. Stanley Hall (1844-1924)

• Established first psychological lab in the US at John  

Hopkins: founded the APA

▪ Mary Whiton Calkins (1863-1930)

• Was the first woman elected president of the APA  

American Psychological Association

• Conducted research in dreams, memory, and personality

o Great Theoretical Frameworks of Psychology  

▪ 1. Structuralism –What is this process?

• ‘Map’ the elements of consciousness (sensations, images,  

feelings) using introspection

▪ 2. Functionalism – Why

• Psychologists must act as ‘detectives’ to discover these  


• Evolutionary aspect still influences modern psychology  

▪ The unconscious is the part of the mind that operates outside of  conscious awareness

▪ Unconscious conflicts determine behavior and personality  

▪ Psychoanalytic Theory – Unconscious mental process shape  

feelings, thoughts, and behaviors  

o New Schools Develop Behaviorism

▪ Ivan Pavlov (1849-1936) – discovers conditioned reflexes

▪ Psychology redefined as the scientific study of observable behavior

Lecture Notes

▪ This is about the dog that salivates to the ring of a bell due to  conditioning

▪ John Watson (1878-1958) – extends approach to human behavior ▪ B.F. Skinner (1904-1990) – further experiments on behavior,  learning, and conditioning

• These three moves Psychology away from Philosophy  

• New Schools Develop

o Cognitive Psychology – the scientific study of how perception, thought,  memory, and reasoning are processed

o A return to an emphasis on mental processes and how they influence  behavior

▪ Whose happier to medal at the Olympics bronze or silver? Bronze,  because they actually got a medal.

• Theoretical Perspectives

o Cognitive Perspective (1950’s – present)

▪ Noam Chomsky & Herbert Simon

▪ Sometimes Psychologists will study their own children sometimes • Behaviorism vs Cognitive

o Behaviorism is an S-R model

▪ Stimulus response

o Cognitive psychology emphasizes the S-O-R model

▪ The organism in the middle interprets that stimulus and produces a  response  

• Biological perspective

o Emphasizes the physical bases of human and animal behavior, including  the nervous, endocrine, and immune systems, and genetics

▪ Neuroscience

Lecture Notes

▪ Focus

▪ Research techniques

o Different from other biological sciences

• Cross-cultural perspective

o Emerged in the 190’s

o Emphasizes diversity of behavior across cultures and the fact that many  earlier psychological findings were not universal

o Important cultural terms:

▪ Ethnocentrism

▪ Individualistic cultures

• Different cultures react to similar situations differently

▪ Collectivistic cultures

• How do we make our decisions

• Evolutionary Perspective

o Reflects renewed interest in Darwin’s work

o Applies the principles of evolution to explain psychological processes o Suggests that most adaptive characteristics are perpetuated through  natural selection

o Analyzes behavior in terms of how it increases a species’ chances to  survive and reproduce  

• Psychology’s three main levels of analysis

o 1. Biological Influences

▪ Genetic predispositions

▪ Genetic mutations

▪ Natural selection of adaptive physiology and behaviors

▪ Genes responding to the environment

o 2. Psychological influences

▪ Learned fears and other learned expectations

▪ Emotional responses

▪ Cognitive processing and perceptual interpretations

o 3. Social-cultural influences

▪ Presence of others

▪ Cultural, societal, and family expectations

▪ Peer and other group influences

▪ Compelling models (such as the media)

o These all lead to a behavior or mental process

• Psychologists and Psychiatrists

o Clinical Psychologists

▪ Trained in the diagnosis, treatment, caused and prevention of  psychological disorders

o Psychiatrist

▪ Have medical degrees followed by specialized training in the  diagnosis, treatment, causes, and prevention of psychological  


▪ Emphasize biological factors and use biomedical therapies

• The profession of Psychology

Lecture Notes

o Basic Research builds psychology’s knowledge bas through research and  training  

o There are many sub specialties of psychology such as clinical, counseling,  general, developmental, educational, social and personal, cognitive,  industrial organizational, biological and experimental, etc.  

o Psychologists work in a wide variety of settings

▪ Universities, colleges, and medical schools

▪ For-profit organizations and self-employment

▪ The federal government

▪ Stat and local government  

New Lecture

• What is good research design?

• Explore the scientific method

• Discuss the ethics of experimentation

• Review statistics

• How do Psychologists Ask and Answer Questions?

• What about intuition and common sense?

o Many people believe that intuition and common sense are enough to bring  forth answers regarding human nature

• Limits of Intuition

o Personal interviewers may rely too much on their “gut feelings” when  meeting with job applicants  

o We like people who are like up

• Hindsight Bias

o This is that “I-knew-it-all-along” phenomenon

o 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.  

• The scientific Attitude and Critical Thinking

o In whatever subfield and in whatever setting, psychologists seek to  maintain a scientific attitude:

▪ Curiosity

▪ Skepticism

▪ Humility

• Its okay to be wrong

o Critical thinking examines: assumptions, disconcerts, hidden values,  evaluates evidence, and assesses conclusions

o Psychologists, like all scientists, use the scientific method to construct  theories that organize, summarize and simplify observations.  

▪ We can theorize that irritating someone leads to them being angry  – we collect data – and so on

• Using the Scientific Method

o Scientific method

PSYC 1301

Aug 25, 2016

Lecture Notes

▪ A set of assumptions, attitudes, and procedures that guide  researchers in creating questions to investigate, in generating  evidence, and in drawing conclusions

• There was an experiment to see if babies can smell their  mothers

o Step 1: Formulate a specific question that can be tested

▪ Form a hypothesis: a tentative statement about the relationship  between two or more variables: a testable prediction or question ▪ Dependent – the variable we measure at the end

o Step 2: Design a study to collect relevant data

▪ Use descriptive or experimental methodologies

o Step 3: Analyze the data to arrive at conclusions

▪ Use statistics to analyze, summarize, and draw conclusions about  the data they have collected

o Step 4: Report the results

▪ The rationale for testing the hypothesis who participated in the  study and how they were selected  

▪ How variables were operationally defined

▪ What procedures or methods were used

▪ How the data were analyzed

▪ What the results seem to suggest

o Scientific Terms

▪ Empirical Evidence – is information acquired by observation or  experimentation

▪ Hypothesis – a testable prediction about the relationship between  at least two events, characteristics, or variables.  

▪ Variable – something that can be changed, such as a characteristic or value. They are generally used in psychology experiments to  determine if changes to one thing result in changes to another.

▪ Operational definition – a statement of the procedures or ways in  which a researcher is going to measure behaviors or qualities.  ▪ Statistically significant – is the probability of some result from a  statistical test occurring by chance.  

• Psychologists look for a probability of 5% or less that the  results are due to chance, which means a 95% chance the  

results are “not” due to chance.  

▪ Meta-analysis – is a study about other studies in order to get an  integrated result. AKA a researcher reviews previously published  studies on a topic, and analyzes the various results to find general  trends across the studies.  

▪ Replication – it’s a way of seeing if the same study can be re created and yield the same results

• The repetition of a research study, generally with different  situations and different subjects, to determine if the basic  

findings of the original study can be generalized to other  

participants and circumstances.
