Question 1
Which research method involves following the same individuals over a long period
of time with multiple assessment points?
A. Cross-sectional study
B. Naturalistic observation
C. Longitudinal study
D. Case study
E. Survey
Correct Answer: C. Longitudinal study
Rationale: A longitudinal study design follows the same individuals over an
extended period, collecting data at multiple time points to observe developmental
changes. This is distinct from cross-sectional studies, which compare different age
groups at a single point in time. Longitudinal research is particularly valuable for
understanding developmental trajectories and individual differences in change over
time .
Question 2
,What is the correct definition of a teratogen?
A. A genetic mutation that causes developmental disorders
B. Agents that interfere with natural growth and produce a birth defect
C. A hormone that triggers the onset of puberty
D. A type of chromosome abnormality
E. A protein essential for fetal brain development
Correct Answer: B. Agents that interfere with natural growth and produce a birth
defect
Rationale: Teratogens are environmental agents such as chemicals, viruses, or
drugs that can reach the embryo or fetus and cause harm during prenatal
development. Their effects depend on three key variables: gestational age at
exposure, the amount of teratogen, and the susceptibility of the developing
organism .
Question 3
Milly and Harry are crazy about each other. Although they have only known each
other for six weeks, they have decided to drive to Las Vegas and get married.
Throughout the brief ceremony, they cannot keep their hands off each other.
Which type of love best describes their relationship?
A. Consummate love
B. Fatuous love
C. Liking
,D. Romantic love
E. Companionate love
Correct Answer: B. Fatuous love
Rationale: Fatuous love, according to Sternberg's triangular theory of love, is
characterized by passion and commitment without intimacy. This type of love
often develops quickly, as seen in whirlwind romances where couples make rapid
decisions about commitment without truly knowing each other. The passion
(intensity and physical attraction) and commitment (decision to marry) are present,
but intimacy (deep emotional connection and understanding) is absent .
Question 4
Which prenatal diagnostic technique involves needle puncture of the amniotic sac
to withdraw fluid for analysis?
A. Chorionic villus sampling (CVS)
B. Ultrasound
C. Amniocentesis
D. Maternal blood screening
E. Fetal MRI
Correct Answer: C. Amniocentesis
Rationale: Amniocentesis is a prenatal diagnostic procedure in which a needle is
inserted through the mother's abdomen into the amniotic sac to withdraw a sample
of amniotic fluid. This fluid contains fetal cells that can be analyzed for
, chromosomal and genetic abnormalities. This procedure is typically performed
between 15 and 20 weeks of gestation .
Question 5
According to research, at what age do most girls in North America finish growing?
A. Approximately age 12
B. Approximately age 14
C. Approximately age 16
D. Approximately age 18
E. Approximately age 20
Correct Answer: C. Approximately age 16
Rationale: Most girls in North America reach their final adult height by
approximately age 16. This is because the growth spurt typically begins around age
10-11, with peak growth velocity occurring around age 12, followed by a gradual
deceleration and eventual cessation of growth when the epiphyseal plates close .
Question 6
What is the primary focus of developmental psychology?
A. Development across the entire human lifespan
B. Changes during infancy and childhood only
C. Physical changes from infancy through adolescence
