__ can lead us astray, __ __ similarly err
IntuitionCommon sense
Define hindsight bias (aka: I-knew-it-all-along phenomenon)
Tendency to believe, after learning an outcome, that one would have foreseen it
Describe the scientific attitude
Being skeptical but not cynical, open but not gullible. Show evidence. Requires humility to reveal nature’s truths
People tend to be ___. We are equally __ at predicting our social behavior. We __ our intuition, but __ __ can help sift reality from illusions
OverconfidentWrongOverestimateScientific inquiry
Scientific attitude is composed of __ , __ , & __
CuriositySkepticismHumility
Define critical thinking
Thinking that doesn’t blindly accept arguments & conclusions. Rather, it examines assumptions, discerns hidden values, evaluates evidence, & assesses conclusions
Define theory
An explanation using an integrated set of principles that organizes observations & predicts behaviors or events (simplifies things, offers useful summary)
Describe the scientific method
Make observations, form theories, refine theories with new observations
Define hypothesis
A testable prediction, often implied by a theory. Gives direction to research
Define replication
Repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants & circumstances
When we urge to see what we expect, it is __ __
Subjective observations
Define operational definition
A statement of the procedures (operations) used to define research variables
What makes a good theory?
Organize & link observed facts & imply hypotheses that offer testable predictions & sometimes, practical applications
What are the 3 research types?
Descriptive, correlational, & experimental
Define case study
An observation technique in which one person is studied in depth in the hope of revealing universal principles
Define survey
A technique for ascertaining the self-reported attitudes or behaviors of people, usually by questioning a representative, random sample of them
Case studies suggest __ for further study. Individuals can be __, so we must use other methods
HypothesesAtypical
Survey answers depend on a question’s __ & choice of __
WordingRespondents
Define false consensus effect
The tendency to overestimate the extent to which others share our beliefs & behaviors
Subtle changes to __ of questions may have large effects
Wording
Define population
All the cases in a group, from which samples may be drawn for a study
For an accurate picture of a population, must use a __ __
Representative sample
Define random sample
A sample that fairly represents a population because each member has an equal chance of inclusion
Think critically & consider the __ before believing __ __
SampleSurvey findings
__ representative samples are better than __ ones
LargeSmall
The temptation to __ from a few vivid but __ cases is nearly irresistible
GeneralizeUnrepresentative
Define naturalistic observation
Observing & recording behavior in naturally occurring situations without trying to manipulate & control the situation.
Goodall paved way for later studies of __ thinking, language, & emotion. Whiten & Byrne saw chimps and baboons use __ to achieve their aims
AnimalDeception
Naturalistic observations doesn’t __ behavior, it __ it
ExplainDescribes
Pace of life is fastest in __ & __ __ & in __ climates. Pace of life is slower in economically __ __ countries
Japan & Western EuropeColderLess-developed
Naturalistic observation can also be used with __ __
Correlational research
Define correlation
A measure of the extent to which 2 factors vary together, & thus of how well either factor predicts the other
Define correlation coefficient
Statistical measure of a relationship: reveals how closely 2 things vary together & how well either one predicts the other. Ranges from -1 to +1
Define scatterplot (aka: scatter gram & scatter diagram)
A graphed cluster of dots, each of which represents the values of 2 variables. The slope of the points suggests the direction of the relationship between the 2 variables. The amount of scatter suggests the strength of the correlation
Little scatter indicates __ correlation
High
Define positive correlation
2 sets of scores tend to rise or fall together
Define negative correlation
2 things relate inversely (1 goes up, other goes down)
Positive and negative correlations have nothing to do with the __ or __. Correlation indicates a __ __
StrengthWeaknessStatistical relationship
