101 EXAM 2026 PRACTICE QUESTIONS
WITH ANSWERS ORIGINAL QUESTIONS,
DETAILED RATIONALES & STUDY GUIDE
1. Which statement most accurately captures the scientific definition
of psychology?
A. The study of mental illness and abnormal behavior
B. The systematic study of behavior and mental processes
C. The study of the brain and nervous system exclusively
D. The philosophical study of consciousness without empirical testing
Answer: B. The systematic study of behavior and mental processes
Rationale: Psychology is broadly defined as the scientific study of
behavior and mental processes. Behavior includes observable actions,
while mental processes include thinking, remembering, perceiving,
feeling, and reasoning. Psychology is broader than the study of mental
disorders and incorporates biological, cognitive, developmental, social,
cultural, and environmental influences.
2. A psychologist wants to determine whether background music
affects students' ability to remember vocabulary words. Students
are randomly assigned either to study with music or in silence, and
their subsequent memory scores are compared. Which research
method is being used?
A. Naturalistic observation
B. Correlational research
C. Experiment
D. Case study
1
,Answer: C. Experiment
Rationale: An experiment involves manipulating an independent
variable and measuring its effect on a dependent variable while
controlling other conditions as much as possible. Here, the presence or
absence of music is the manipulated independent variable, while
vocabulary performance is the dependent variable. Random
assignment strengthens the researcher's ability to make causal
conclusions.
3. A researcher finds that students who report more hours of sleep
tend to have higher examination scores. The correlation coefficient
is +0.72. What is the best interpretation?
A. Sleep definitely causes higher examination scores
B. Examination performance causes students to sleep more
C. There is a relatively strong positive relationship between sleep and
examination performance
D. There is no meaningful relationship between the variables
Answer: C. There is a relatively strong positive relationship between
sleep and examination performance
Rationale: A positive correlation means that higher values of one
variable tend to be associated with higher values of the other. A
coefficient of +0.72 indicates a fairly strong positive association.
However, correlation alone does not establish causation because other
variables could explain the relationship.
4. Which situation best illustrates a third-variable problem in
correlational research?
A. Researchers manipulate caffeine consumption
B. Students are randomly assigned to two groups
2
,C. Exercise and mood are correlated, but sleep quality influences both
D. Researchers repeat the same experiment twice
Answer: C. Exercise and mood are correlated, but sleep quality
influences both
Rationale: A third variable is an outside factor that may influence
both variables being studied and therefore create or distort their
apparent relationship. If people who exercise more also sleep better,
and better sleep improves mood, the relationship between exercise and
mood may partly reflect sleep quality rather than exercise alone.
5. Which principle is most important when evaluating an
extraordinary psychological claim?
A. Whether the claim is popular on social media
B. Whether many people personally believe it
C. Whether credible empirical evidence supports it
D. Whether the claim sounds intuitively reasonable
Answer: C. Whether credible empirical evidence supports it
Rationale: Psychology relies on empirical evidence and critical
thinking rather than popularity, intuition, anecdotal experiences, or
unsupported claims. A scientifically credible claim should be testable,
supported by evidence, and open to revision when new evidence
becomes available.
6. In an experiment testing whether a new study technique improves
exam performance, researchers assign students to either use the new
technique or their normal study method. What is the dependent
variable?
3
, A. The study technique
B. Assignment to the experimental group
C. Examination performance
D. The students' prior educational experience
Answer: C. Examination performance
Rationale: The independent variable is what researchers manipulate—
in this case, study technique. The dependent variable is the outcome
measured to determine whether the manipulation produced an effect.
Therefore, examination performance is the dependent variable.
7. Which ethical principle requires researchers to explain relevant
aspects of a study to participants before they agree to participate?
A. Debriefing
B. Informed consent
C. Random assignment
D. Replication
Answer: B. Informed consent
Rationale: Informed consent requires participants to receive
appropriate information about participation, including relevant
procedures, risks, and their rights, before voluntarily agreeing to
participate. Ethical research also requires protection from
unnecessary harm and respect for participants' welfare and autonomy.
8. Which structure is the basic functional unit of the nervous
system?
A. Hormone
B. Neuron
