Unit 2- Research and Social Psych Flashcards
Hindsight bias
I knew it all along phenom- our tendency to want to be right (and don’t want to be wrong), so we say that after the event we knew that it would happen
Overconfidence
we tend to be more confident than correct (specifically to factual questions)
Wording effect
Changing the way to word questions or statements so they are more appealing
Correlate
how closely two things vary and how well they predict each other (test scores correlate to success of school)
Ethics code
a study/experiment must follow the ethics code
-Informed consent
-Protection from harm
-Confidentiality
-Debrief
positive correlation
two sets of scores tend to rise and fall together (people’s height and weight. taller people weigh more)
r= .8 strong positive correlation
r= .4 weak positive correlation
negative correlation
set of scores change in opposite directions (people’s height and their distance to the ceiling. taller shorter distance to ceiling, shorter longer distance to ceiling)
r= -.8 strong
r= -.4 weak
Skewed distribution
when a representation of scores are lacking symmetry around average value
Statistical significance
when comparing experimental & control groups, the difference must be large enough to be considered statistically significant
Gambler’s fallacy
we tend to try and connect order to random sequences to help us make sense of the world (when C is the correct answer, but the past 5 questions were also C we may switch our answer)
Normal curve
the bell shaped curve
(from left to right)
99% 95% 68% 95% 99%
2.1% 13% 34% 13% 2.1%
Cognitive dissonance
Happens when we feel guilty. It changes our attitude and behavior for the future
Fundamental attribution error
tendency to mistakenly attributing thoughts and feelings about a person rather than focusing on the situation (behind a really slow driver and get road rage, but maybe it’s an old person, or a new driver, or the person’s car is really old and doesn’t work well)
foot-in-the-door phenom
persuasive strategy; we first tend to agree to a small request and then bigger and bigger requests
peripheral route v. central route persuasion
peripheral is fast feelings (celebrities or influencers we like tell us to buy this product and we buy it)
central- changes our thinking with evidence (we might not think climate change is bad until we see stats on ice melting, the rising temps, etc)
