1. Which statement most accurately defines psychology as it is
taught in PSYC C1000?
A. The study of abnormal behavior exclusively through clinical
observation
B. The scientific study of behavior and mental processes
C. The philosophical study of consciousness without empirical testing
D. The medical treatment of neurological disorders
Answer: B. The scientific study of behavior and mental processes
Rationale: Psychology is broadly defined as the scientific study of
behavior and mental processes. Behavior includes observable actions,
whereas mental processes include thoughts, memories, emotions,
perceptions, and decision-making. Psychology differs from purely
philosophical speculation because psychologists use systematic
observation, measurement, experimentation, and other empirical
methods to evaluate explanations of behavior.
2. A psychologist notices that students who sleep at least seven hours
tend to perform better on morning examinations. She wants to
determine whether increasing sleep actually causes improved
academic performance. Which research approach would provide
the strongest evidence for causation?
1
,A. Naturalistic observation
B. Correlational research
C. Randomized controlled experiment
D. Case study
Answer: C. Randomized controlled experiment
Rationale: An experiment allows researchers to manipulate an
independent variable—in this case, sleep duration—and measure its
effect on a dependent variable such as examination performance.
Random assignment helps distribute preexisting differences between
participants across conditions. Correlation can demonstrate an
association but cannot by itself establish causation because of possible
third variables or reverse causation.
3. A researcher finds that students who spend more hours exercising
each week tend to report lower levels of stress. What does this
finding demonstrate?
A. Exercise definitely causes lower stress
B. Stress definitely causes people to exercise less
C. There is a relationship between exercise and reported stress
D. The study proves that exercise is a treatment for anxiety disorders
Answer: C. There is a relationship between exercise and reported
stress
Rationale: A correlation indicates that two variables are statistically
related, but it does not establish which variable causes the other or
whether a third variable explains the relationship. For example,
overall health, income, work schedule, or social support could
influence both exercise and stress.
4. Which statement best describes an operational definition?
2
,A. A broad philosophical explanation of a concept
B. A precise description of how a variable will be measured or
manipulated
C. A prediction that has already been proven correct
D. A participant's personal interpretation of a research question
Answer: B. A precise description of how a variable will be measured
or manipulated
Rationale: Operational definitions translate abstract concepts into
measurable procedures. For example, instead of simply studying
"stress," a researcher might operationally define stress as a
participant's score on a validated stress questionnaire or a specific
physiological measure. Operationalization makes research concepts
observable and testable.
5. Which principle is most directly associated with informed consent
in psychological research?
A. Participants must be guaranteed that their hypothesis will be
supported
B. Participants should understand relevant information about
participation before agreeing
C. Researchers may conceal all risks from participants
D. Participants must remain in a study once they enroll
Answer: B. Participants should understand relevant information
about participation before agreeing
Rationale: Informed consent is an ethical requirement designed to
ensure that participants understand relevant aspects of a research
study before voluntarily participating. Ethical research also includes
protections concerning confidentiality, risk, deception, withdrawal,
and appropriate treatment of participants.

, 6. A researcher wants to determine whether a new study technique
improves examination scores. Students are randomly assigned either
to use the new technique or to use their normal study method. What
is the independent variable?
A. Examination score
B. Student intelligence
C. Study technique
D. Number of students
Answer: C. Study technique
Rationale: The independent variable is the factor deliberately
manipulated by the researcher. Here, the researcher manipulates
which study technique students use. Examination performance is the
dependent variable because it is measured to determine whether the
manipulation produced an effect.
7. Which structure is primarily responsible for transmitting
information from one neuron to another across a tiny gap?
A. Myelin sheath
B. Synapse
C. Cell body
D. Dendrite
Answer: B. Synapse
Rationale: The synapse is the junction between neurons where
communication occurs, typically involving the release of
neurotransmitters from one neuron and their reception by another.
The myelin sheath helps speed neural transmission along axons, while
dendrites primarily receive incoming signals.
