SECTION 1: THEORETICAL PERSPECTIVES & RESEARCH METHODS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A graduate student sits on a bench near a preschool playground and records how often
children share toys during free play. She does not interact with the children, alter the
environment, or inform them that they are being observed.
A. Naturalistic observation allows behavior to be studied in real-world contexts without
artificial constraints ✓ CORRECT
B. Structured observation would provide more objective data because the environment
is controlled
C. A case study approach would yield more generalizable findings about sharing
behavior
D. Correlational research is necessary to establish that sharing causes later academic
success
Correct Answer: A
,Rationale: Naturalistic observation is the method described because the researcher is
recording spontaneous behavior in an everyday setting without intervention. Option B is
incorrect because structured observation involves creating a controlled setting, which
contradicts the playground scenario. This method is particularly useful for studying
social behaviors that children might alter if they knew they were in an experiment.
Question 2 of 50
A 5-year-old boy hides behind a living room curtain and announces to his mother that
she cannot see him. When she explains that she can still see his feet, he insists she
must be wrong because he cannot see her.
A. The child is demonstrating animism by attributing life to inanimate objects
B. This egocentrism reflects preoperational thought typical of children in this age range
✓ CORRECT
C. The child has reached concrete operational stage and should understand others'
viewpoints
D. This behavior indicates a theory of mind deficit requiring developmental screening
Correct Answer: B
Rationale: Egocentrism, the inability to distinguish one's own perspective from another's,
is a hallmark of Piaget's preoperational stage from ages 2 to 7. Option A is incorrect
because animism involves believing objects are alive, not failing to recognize different
visual perspectives. Preschool teachers often see this when children hide by covering
their own eyes, assuming they are now invisible to others.
Question 3 of 50
A developmental psychologist is studying aggression in elementary school children.
She worries that the children might behave differently simply because they know an
adult is watching them during recess.
A. Random assignment will eliminate this bias by distributing it evenly across groups
,B. A double-blind design prevents participants from knowing the study's hypothesis
C. The Hawthorne effect threatens external validity when behavior changes under
observation ✓ CORRECT
D. Informed consent procedures are the primary method to reduce reactivity in
participants
Correct Answer: C
Rationale: The Hawthorne effect occurs when individuals modify their behavior simply
because they are aware of being observed, which threatens the naturalness of the data
collected. Option A is incorrect because random assignment addresses selection bias
and internal validity, not reactivity to being observed. Researchers often use unobtrusive
measures or habituation periods to minimize this effect.
Question 4 of 50
A psychology major is reviewing Erikson's psychosocial stages for an upcoming exam.
She focuses on the first stage and notes that an infant whose cries are consistently met
with feeding and comfort develops a basic sense of the world as predictable and safe.
A. The first stage centers on developing competence through school achievement
B. Initiative versus guilt involves learning to lead and plan without excessive punishment
C. Identity versus role confusion dominates the challenges of the toddler years
D. Infants who receive consistent caregiving develop a sense of trust in the world ✓
CORRECT
Correct Answer: D
Rationale: Erikson's first psychosocial stage, trust versus mistrust, occurs during infancy
when consistent, responsive caregiving fosters a fundamental sense of security in the
environment. Option A is incorrect because competence through school achievement
describes industry versus inferiority, which occurs during middle childhood. Reliable
caregiving in infancy lays the foundation for future social and emotional development.
Question 5 of 50
, A mother gives her 4-year-old daughter a sticker every time the child makes her bed
without being asked. Over three weeks, the frequency of bed-making increases from
once a week to five times a week.
A. Positive reinforcement increases the likelihood of the bed-making behavior recurring
✓ CORRECT
B. Negative reinforcement is occurring because an unpleasant task is being avoided
C. The sticker serves as punishment because it draws attention to a previously ignored
behavior
D. This is classical conditioning because the bed becomes associated with the sticker
Correct Answer: A
Rationale: Positive reinforcement involves presenting a desirable stimulus, such as a
sticker, after a behavior to strengthen its future occurrence, which is exactly what the
parent is doing. Option B is incorrect because negative reinforcement involves removing
an aversive stimulus, not adding a reward. Behaviorist principles are frequently applied
in parenting and classroom management to shape desired behaviors.
Question 6 of 50
A researcher wants to compare memory performance across age groups but has only
one semester to collect data. She tests a group of 5-year-olds and a separate group of
10-year-olds on the same list of words during the same week.
A. This longitudinal design will track the same children as they grow older
B. A cross-sectional approach allows quick comparison across age groups at one time
point ✓ CORRECT
C. The study uses a case study method to examine memory in exceptional children
D. This correlational research can prove that aging causes memory improvements
Correct Answer: B
Rationale: Cross-sectional research compares different age groups simultaneously,
making it efficient for identifying age-related differences without waiting years for
participants to mature. Option A is incorrect because longitudinal designs follow the
