1. INTRODUCTION
The University of Oklahoma PSY 1113 Introductory Psychology course introduces students to
the scientific study of human behavior and mental processes. This practice question bank is
designed for students preparing for introductory psychology assessments, reviewing course
concepts, and strengthening their ability to apply psychological theories to real-world situations.
The questions cover major areas of psychology, including biological foundations of behavior,
sensation and perception, learning, memory, cognition, development, motivation, emotion,
personality, social psychology, psychological disorders, and research methods. Rather than
focusing exclusively on memorizing definitions, the questions emphasize application,
interpretation, critical thinking, and evaluating competing explanations.
Each multiple-choice question contains four answer options, followed by the correct answer and
a detailed rationale explaining why the selected answer is best and why the alternatives are less
appropriate. Students can use the material for independent revision, timed practice, identifying
knowledge gaps, and reinforcing difficult concepts.
For the best results, attempt each question before reviewing its answer, record the topics you
miss, and revisit the relevant course materials. This resource supports exam preparation but
should be used alongside the instructor's syllabus, assigned readings, and official course
guidance.

Domain 1: Research Methods and Scientific Reasoning
Q1: A researcher wants to determine whether sleep deprivation impairs students' ability to solve
complex problems. Students are randomly assigned to sleep either eight hours or four hours
before completing the same problem-solving test. Which feature most strongly supports a causal
conclusion?
A) The students complete the test in the same classroom.
B) The researcher manipulates sleep duration and randomly assigns participants to conditions.
C) The researcher measures students' usual academic performance.
D) The researcher recruits students who report being tired.
Rationale: Random assignment helps distribute preexisting differences across conditions, while
manipulating sleep duration establishes the independent variable. Together, these features
strengthen causal inference. A standardized classroom controls some environmental variation but
does not establish causation. Measuring usual academic performance is observational and may
involve confounding variables. Recruiting tired students introduces selection bias and does not
create a controlled comparison.
Q2: A study finds a strong negative correlation between daily exercise and reported stress.
Which conclusion is scientifically justified?
A) Exercise is the only cause of lower stress.
B) Lower stress necessarily causes more exercise.
C) Greater exercise is associated with lower reported stress, but causation is not established.
D) The relationship must be explained by measurement error.
Rationale: A negative correlation indicates that higher values of one variable tend to accompany
lower values of the other. It does not determine causation or direction. Exercise might reduce
stress, lower stress might make exercise easier, or a third variable might influence both.
Measurement error is possible in any study but cannot be concluded from the correlation alone.
Q3: A psychologist develops a questionnaire intended to measure anxiety. Participants complete
it twice, two weeks apart, under similar conditions, and receive nearly identical scores. What
property is most directly supported?
A) Construct validity.
B) Test–retest reliability.
, 4|Page
C) Inter-rater reliability.
D) Experimental control.
Rationale: Test–retest reliability concerns the consistency of scores across repeated
administrations when the underlying characteristic is expected to remain relatively stable.
Construct validity concerns whether the questionnaire actually measures anxiety. Inter-rater
reliability concerns agreement between different evaluators. Experimental control refers to
managing alternative explanations in research.
Q4: A researcher observes that students who drink more coffee tend to earn higher examination
scores. Students who drink coffee also tend to study longer. Which interpretation identifies a
potential confound?
A) Examination scores are necessarily unreliable.
B) Coffee consumption must directly improve intelligence.
C) Studying longer is the dependent variable in every possible design.
D) Study time may influence both coffee consumption and examination performance, helping
explain their association.
Rationale: A confounding variable is related to the variables under investigation and can provide
an alternative explanation for an observed association. Study time could increase coffee
consumption and improve performance. The correlation does not establish an effect on
intelligence, and the reliability of scores cannot be inferred from this relationship. Whether study
time is a dependent variable depends on the actual design.
Q5: A researcher tells participants that a new memory supplement is expected to improve recall.
Participants receiving an inactive pill subsequently report better memory. Which design feature
would best help distinguish the supplement's specific effects from expectations?
A) Allow participants to choose whether they receive the supplement.
B) Tell the supplement group that improvement is guaranteed.
C) Use a randomized, double-blind, placebo-controlled design.
D) Test only participants who report improvement.
Rationale: Random assignment reduces systematic group differences, a placebo controls for
receiving a treatment-like intervention, and double blinding reduces expectancy effects among
participants and researchers. Allowing self-selection introduces selection bias. Guaranteeing
improvement increases demand characteristics. Selecting only improved participants creates a
biased sample of outcomes.
