1. Which statement best captures the scientific definition of
psychology?
A. The study of only mental illnesses and abnormal behavior
B. The systematic scientific study of behavior and mental processes
C. The study of philosophical questions concerning human existence
D. The treatment of neurological diseases through medication
Answer: B. The systematic scientific study of behavior and mental
processes
Rationale: Psychology is a scientific discipline concerned with
observable behavior as well as internal mental processes such as
thinking, remembering, perceiving, feeling, and reasoning. Its
scientific status comes from its reliance on systematic observation,
empirical evidence, testable hypotheses, and research methods rather
than personal opinion or speculation.
2. A psychologist proposes that students who regularly sleep at least
eight hours will perform better on memory tests. What is the
primary role of the hypothesis in this situation?
1
,A. It proves that sleep improves memory
B. It provides a testable prediction derived from an idea or theory
C. It eliminates the need to collect empirical data
D. It guarantees that the researcher will obtain statistically significant
results
Answer: B. It provides a testable prediction derived from an idea or
theory
Rationale: A hypothesis is a specific, testable prediction. The
researcher must collect evidence to determine whether the prediction is
supported. A hypothesis does not prove anything by itself, and a
researcher must remain open to findings that contradict the original
prediction.
3. A researcher wants to determine whether background music
affects students' test performance. Students are randomly assigned
either to complete a test with music or without music. What is the
independent variable?
A. Students' test scores
B. Students' intelligence levels
C. Presence or absence of background music
D. Number of questions answered correctly
Answer: C. Presence or absence of background music
Rationale: The independent variable is the variable that the researcher
deliberately manipulates. In this experiment, the researcher controls
whether participants hear music. Test performance is the dependent
variable because it is measured to determine whether it changes as a
consequence of the manipulation.
2
,4. Which research method would be most appropriate for
determining whether two variables are statistically related without
manipulating either variable?
A. Correlational research
B. Experimental research
C. Double-blind experimental research
D. Case-control experimentation
Answer: A. Correlational research
Rationale: Correlational research examines relationships between
variables as they naturally occur. For example, researchers could
examine whether hours of sleep are associated with GPA without
assigning participants to specific sleep schedules. Correlation can
identify relationships but cannot, by itself, establish causation.
5. A researcher finds that people who exercise more frequently tend
to report lower stress levels. Which conclusion is scientifically
justified?
A. Exercise definitely causes lower stress
B. Stress definitely causes people to exercise less
C. Exercise and reported stress are negatively correlated
D. The relationship proves that exercise is the only cause of stress
reduction
Answer: C. Exercise and reported stress are negatively correlated
Rationale: A negative correlation means that as one variable
increases, the other tends to decrease. However, correlation does not
establish causation because third variables or reverse causation may
explain the relationship.
3
, 6. Why is random assignment particularly important in an
experiment?
A. It guarantees that every participant will respond identically
B. It helps distribute preexisting participant differences across
experimental groups
C. It guarantees that the hypothesis will be supported
D. It eliminates the need for a control group
Answer: B. It helps distribute preexisting participant differences
across experimental groups
Rationale: Random assignment helps create groups that are
approximately equivalent before the independent variable is
manipulated. This strengthens causal inference because differences in
the dependent variable are less likely to result from preexisting
differences between participants.
7. Which situation best demonstrates the placebo effect?
A. Participants improve because they consciously manipulate their
results
B. Participants experience improvement after receiving an inactive
treatment they believe is effective
C. Participants refuse treatment because they distrust researchers
D. Participants improve only when researchers know their treatment
assignment
Answer: B. Participants experience improvement after receiving an
inactive treatment they believe is effective
Rationale: The placebo effect occurs when expectations associated
with receiving a treatment contribute to changes in symptoms or
behavior, even though the treatment itself lacks the active therapeutic
ingredient being studied.
