- gives a sense a control
overconfidence
tend to think we know more more than we do
apophenia
perception that unrelated events are related
- gamblers believe they have a system to beat the house
pareidolia
perception of significant patterns/images
- ex: seeing faces in inanimate objects
empirical
based on systematic observations
what are the goals of psych?
to describe, explain, predict, influence mental processes/behaviors
deductive reasoning
begins w/ hypothesis and is then used to reach logical conclusions abour real world
(start w/ hypo, end with conclusion)
inductive reasoning
empirical observations lead to new ideas (conclusion may not be right)
(start w/ conclusion, end w/ hypo)
theory
set of statements used to describe a phenomenon, suggests future research
- used to provide a model for understanding human thoughts/emotions /behs
hypothesis
testable prediction; implied by theory
falsifiable
capable of being shown to be incorrect
(denial)
case/clinical study
in depth study of one person/small group
- (rare: like alien-limb syndrome)
generalizing
ability to apply findings of a research project to larger groups
naturalistic observation
observing people in natural environments
hawthorne effect
people m ay change their beh simply because they know their being observed
observer bias
observers closely involved in research project; may unconsicously skew observations to fit expectations
inter-rater reliability
access consistency of observation by diff. observers
- need to verify diff. observers are recording same data
survey research
answering questions
wording effects
questions should be written in a way where theyre clear/concise
sampling effects
dont just apply surveys (anytime we do research)
population
everyone in group being studied
sample
subset of population (specific group)
representative sample
has the same characteristics as the population as a whole
- has to have the same ratio of men-woman/same demographics
random assignment
random
