1. A psychologist wants to determine whether a particular behavior is
influenced by genetic factors, environmental experiences, or an
interaction between the two. Which perspective of psychology
would most directly emphasize the role of inherited characteristics
and evolutionary processes?
A. Behavioral perspective
B. Biological perspective
C. Humanistic perspective
D. Sociocultural perspective
Answer: B. Biological perspective
Rationale: The biological perspective examines how genes, brain
structures, neurotransmitters, hormones, and other physiological
mechanisms influence behavior and mental processes. Although
evolutionary psychology also considers adaptation and inherited
tendencies, the biological perspective most directly addresses the
physiological and genetic foundations of behavior.
2. Which statement best illustrates the scientific approach used by
psychologists?
1
,A. A psychologist accepts a popular explanation because many people
believe it.
B. A psychologist develops a testable hypothesis and systematically
collects evidence.
C. A psychologist relies primarily on personal experiences to determine
whether a theory is correct.
D. A psychologist considers a behavior scientifically established when it
seems intuitively reasonable.
Answer: B. A psychologist develops a testable hypothesis and
systematically collects evidence.
Rationale: Psychology uses empirical methods to evaluate
explanations of behavior. A hypothesis must be testable, and
psychologists collect systematic observations or measurements to
determine whether evidence supports or contradicts the hypothesis.
Popularity, intuition, and anecdotal experience do not constitute
sufficient scientific evidence.
3. A researcher observes 500 college students and records how many
hours they sleep each night and their scores on a memory test. The
researcher finds that students who sleep more tend to score higher
on the memory test. What type of research design is being
described?
A. Correlational research
B. Experimental research
C. Case study
D. Naturalistic observation
Answer: A. Correlational research
Rationale: The researcher is measuring two naturally occurring
variables—sleep duration and memory performance—and examining
2
,their relationship without manipulating either variable. This is
correlational research. Correlation can reveal whether variables are
related, but it cannot by itself establish that increased sleep causes
better memory.
4. A researcher randomly assigns participants to either receive
caffeine or a placebo and then measures their reaction time. What
is the primary advantage of randomly assigning participants?
A. It guarantees that every participant will behave identically.
B. It eliminates the need for a control group.
C. It helps distribute preexisting differences between groups.
D. It guarantees that the experiment will produce statistically significant
results.
Answer: C. It helps distribute preexisting differences between
groups.
Rationale: Random assignment increases the likelihood that
participant characteristics—such as age, personality, baseline ability,
or prior caffeine consumption—are distributed relatively evenly
between experimental conditions. This strengthens the researcher's
ability to determine whether the manipulated independent variable
caused differences in the dependent variable.
5. In an experiment investigating whether background music affects
reading comprehension, participants either read with music or in
silence. Their comprehension scores are then measured. What is
the dependent variable?
A. Presence or absence of music
B. Reading comprehension score
3
, C. Type of participant selected
D. Amount of time spent recruiting participants
Answer: B. Reading comprehension score
Rationale: The dependent variable is the outcome that the researcher
measures to determine whether it changes as a result of the
independent variable. Here, background music is manipulated, while
reading comprehension is measured. Therefore, comprehension score
is the dependent variable.
6. Which ethical principle requires researchers to explain the general
nature of a study to participants and obtain their voluntary
agreement to participate?
A. Debriefing
B. Informed consent
C. Random assignment
D. Confidentiality
Answer: B. Informed consent
Rationale: Informed consent means participants receive appropriate
information about the research and voluntarily agree to participate.
Researchers must also follow applicable ethical requirements
concerning risks, privacy, deception, withdrawal rights, and protection
from unnecessary harm.
7. A psychologist studies a child who has an extremely rare
neurological disorder and conducts extensive interviews,
observations, and psychological assessments over several years.
Which research method is most appropriate?
