OPENSTAX PSYCHOLOGY CHAPTERS ONE
TO FOUR MULTIPLE CHOICE 2026 FULL
QUESTIONS WITH CORRECT ANSWERS
GRADED A+
⩥ attrition. Answer: reduction in number of research participants as
some drop out of the study over time
⩥ cause-and-effect relationship. Answer: changes in one variable cause
the changes in the other variable; can be
determined only through an experimental research design
⩥ case study. Answer: in depth investigations of a single or few people
⩥ confirmation bias. Answer: tendency to ignore evidence that disproves
ideas or beliefs
⩥ confounding variable. Answer: unanticipated outside factor that
affects both variables of interest, often giving the false impression that
changes in one variable causes changes in the other variable, when, in
actuality, the outside factor causes changes in both variables
,⩥ control group. Answer: serves as a basis for comparison and controls
for chance factors that might influence the results of the study—by
holding such factors constant across groups so that the experimental
manipulation is the only difference between groups
⩥ correlation. Answer: relationship between two or more variables;
when two variables are correlated, one variable changes as the other
does
⩥ cross-sectional research. Answer: compares multiple segments of a
population at the same time
⩥ debriefing. Answer: when an experiment involved deception,
participants are told complete and truthful
information about the experiment at its conclusion
⩥ deception. Answer: purposely misleading experiment participants in
order to maintain the integrity of the experiment
⩥ deductive reasoning. Answer: results are predicted based on a general
premise (hypothesis)
⩥ dependent variable. Answer: the variable that is being measured,
changes due to independent variable change
, ⩥ double-blind study. Answer: experiment in which both the researchers
and the participants are blind to group assignments
⩥ empirical. Answer: tangible evidence that can be observed, regardless
of who is observing
⩥ experimental group. Answer: group designed to answer the research
question; experimental manipulation is the only difference between the
experimental and control groups, so any differences between the two are
due to experimental manipulation rather than chance
⩥ experimenter bias. Answer: researcher expectations skew the results
of the study
⩥ fact. Answer: (view and other people agree) objective and verifiable
observation, established using evidence collected through empirical
research
⩥ falsifiable. Answer: (capable of being shown incorrect) able to be
disproven by experimental results
⩥ generalize. Answer: refers to ability to apply the findings of a research
project to almost all people (should be for all people)
