Hindsight bias

tendency for people to exaggerate how much they could have predicted an outcome after knowing that it occurred

Scientific Method

Question> Hypotheses > Theory


cannot test a theory

Basic Research

Used to answer general questions


ex. fear appeal

Applied research

research conducted to solve a particular problem; such as trying to decrease discrimination and prejudices

Operational

concepts need to be defined before investigated ex. Satisfaction in a romantic relationship, happiness?


Happiness is the willingness to stay in the relationship



construct validity

extent to which a test measures what it is supposed to measure


ex. measuring your will to stay in relationship not how long

self-reports

are survey(data collection)

Survey advantages

easy, cheap, free, and fast

Survey Disadvantages

Wording effects like;


words people do not understand


confusing grammar


double negatives


words mean same thing but create diff action


(forbid vs. allow)


Social Desirability

tendency for surveyors to answer questions in a manner that will be view favorably by others



Retroactive

change how we think about things, to feel good about ourselves


ex. break ups, blame the other

representative sample

the random sample should be representative of the interest sample; the group of interest

Random sample

a sample taken from the population of interest; each member of the population has an equal chance of being a participant

convenience sample

made up of people who are easy to reach

observational designs

finding data; once you start changing the environment you start to escape from this

naturalistic observation

a method in observing people in their normal environment

Adv. to naturalistic observation

the experimenters act more normal

Disadvantage of naturalistic observation

do not have as much control on the experiment

ethnography

the scientific description of the customs of individual people and cultures; they are bias to the culture they come from

Laboratory observation advantage

researchers can control as much as possible

Laboratory observation disadvantage

you know you are in a study, behavior may change; extremely limited to the behaviors we can observe


ex. cannot observe emotions only facial expressions

ethnocentric

what happens in your culture is correct

infrequent behavior

during an emergency

research design

what kinds of questions can i answer now with the data collection

descriptive research

provides evidence that behavior is occurring but not why it is occurring

correlational design

technique in which two or more variables are systematically measured and a relationship between them is assessed

correlation coefficient

describe strength of relationship or if theres a relationship between two variables so that one can be predicted from the other

positive correlation

increase or decrease together(same direction)


ex. violent video games

negative correlation

one increases the other decreases (opposite direction)


ex. more sleep you get, less tired you feel

range of correlation

+1 to -1; cannot show cause and effect

closer to 1

stronger the relationship

closer to 0

weaker the relationship

methodology

-low self-esteem could cause depression


-Depression can cause low self-esteem


-Distressing events or biological predisposition could cause low self-esteem and depression

Experimentation

Determines cause and effect

Experimentation: variables are manipulated to observe the effect on other variables
ex. type of food fed as a baby- how this effects development of the baby; measure IQ at 3 is there a difference between breast feeding and formula

Experimentation: variables are kept constant

ex. trying to keep the amount fed the same, day/hour/ounces

Independent variables

variable that is manipulated


ex. formula or breast milk

Dependent Variable

variable being measured


ex. IQ at age 3 in baby food test


depends on what happens in independent variable


ex. IQ depends on what baby food you were fed

Control variables

control as much as possible in ethical guidelines to create as little differences as possible


ex. how much food you can feed your baby

experimental condition

participants who are exposed to the independent variable

control condition

participants who are NOT exposed to the independent variable; acting as the comparison as the baseline

Random assignment to conditions

no control, want completely random; 1st person in experimental, 2nd in control...

Cofound

variables that should have been held constant but were accidentally varied

Internal validity

the degree to which differences in the DV are due to differences in the IV

Double Blind Study

neither the experimenter or the participant no who's in what group

Experimenter expectancy effect/experimenter bias

a form of reactivity in which a researcher's cognitive bias causes them to subconsciously influence the participants of an experiment

ideal

an image of the perfect self towards which the ego should aspire

single blind study

the participant doesn't know which group

external validity

our ability to generalize; the degree to which findings can be applied/ generalized to other settings and/or samples

experimental realism

the extent to which the experimental procedures are involving to the participants and lead them to behave naturally; reduce the fact that they are in an experiment

Cover Story

Psychologist will lie to you

Mundane realism

experiment is done in a naturally occurred situation; resembles real world

field experiment

where the people are

research ethics

informed consent; gives you info about study and what you will be doing, any risks

minimal risk

losing time out of your day

Confidentiality

cannot talk about your results together

debriefing

questions can be asked, one can ask experimenter not to use data in study, experimenter can tell participants if they were lied to

Deception

lying; as long as it does not change your ability to give consent

Confederate

people instructed to do a specific thing at a specific time
