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 |
|
