What is psychology?
Psychology is the scientific study of behavior and mental processes. The goal is to improve the human condition.
Wilhelm Wundt
The father of psychology.
Edward Titchener
Another founding father of psych. Known for structuralism, and for bringing psych to the U.S.
William James
Functionalism.
Margaret Washburn
First woman to get a PhD in psych.
Francis Cecil Sumner
First African American to get a PhD in psych.
Sigmund Freud
Psychodynamics.
B.F. Skinner and Watson
Developed behaviorism.
Pavlov
Also developed behaviorism. Did the bells when it was time to feed the dogs to train them to salivate. Classical conditioning.
Structuralism(introspection)
The mind and thoughts. Looking at the structure of the brain.
Functionalism
Mind processes and how they function.
Gestalt Psychology
Big picture psychology. (WWII Jewish refugees)
Psychodynamic
Young childhood experiences influenced how people would act later in life.
Behaviorism
conditioning people through rewards/consequences.
Humanism
The human experience,
Cognitive Psychology
Our thoughts are what influence our behavior
Sociocultural psychology
How society and our culture influence our psychology
Evolutionary psychology
What biological changes are going to influence behavior.
Biopsychosocial
The interconnection between biological, psychological and socio-environmental factors and how they effect your health
Null hypothesis vs. alternative hypothesis
Null is whatever the outcome is, nothing will happen. Alternative is something will happen. (Anxiety doesn’t have an effect on test scores vs. anxiety does have an effect on test scores)
Empirical/empiricism
Basing results off of evidence.
Falsifiability
When we research something, there has to be another side to it, and it has to be falsified. It has to be something that can be proven to be untrue. (You can’t research whether or not the water bottle’s color is purple or not. It just is purple)
Inductive vs. deductive reasoning
Inductive reasoning is a positive thing. If something happens, another thing will happen. Deductive is if something happens, another thing will NOT happen.
P-value & significance testing
P value is a significant test. It’s testing whether or not your results are random chance, or are valid results. You can’t a p-value of less than 5%.
Objective vs. subjective
Objective is unbiased facts. Subjective is biased, and opinionated.
Type i error vs. type ii error.
A type one error is a false positive. SHOULD be negative. (Told a man that he’s pregnant). A type two error is a false negative SHOULD be positive (told a pregnant woman she is not pregnant).
Correlation coefficient r
Measures the direction and the magnitude of the relationship between two things. As one goes up, the other goes up. The closer the number is two one, the stronger the relationship will be.
Longitudinal design
When you study one group of people over a long period of time.
Cross sectional
A snapshot study. Multiple groups of people at one point in time.
Experimenter effect
When the experimenter phrases things or acts in a certain way that makes the participant act in favor to the hypothesis.
The 5 guidelines in the code of ethics
Informed consent (tell people what’s going on), confidentiality (you NEVER leak names), privacy (nothing about your study is going to threaten the person’s privacy), benefits outweigh risk (the study has to be getting you good information), deception studies/debriefing (you have to debrief the people after).
“real-world” vs. laboratory research
Real world is like an observational study (great external validity). Laboratory is running an experiment where you control the variables (great internal validity)
Internal vs. external validity
Internal validity means that inside the study, all of the questions are measuring what they say you’re going to study. Eternal validity is how well your study is going to apply to the real world.
cohort effect
When a certain group of people are all going to act the same way/or all act different from another group of people.
Random assignment vs. random sampling
Attrition
When people drop out of your study.
Independent vs. dependent variable
Independent=the thing that you manipulate/change. Dependent=what you’re measuring.
correlation
If one goes up, another goes up (positive) if one goes down the other goes down (negative)
Exact replication
Taking the study and doing it again exactly.
Conceptual replication
Taking the same study, keep it how it is, but change one aspect about it. Makes for more specific findings.
Open science replication rate
Only 36% of studies are replicated.
Potential solutions to the replication crisis
Publish findings that were not significant too.
Publish replication attempts no matter what.
Open data/access journals.
Monozygotic vs. dizygotic twins
Identical and fraternal twins.
Nature vs. Nurture
The question of how much genetics and how much our environment shapes who we are.
Behavioral genetics
Adoption studies
Help us see how much nature impacts development, and how much nurture impacts. (This is because identical twins have the exact same dna) Think parent trap.
