EPPP Developmental Psychology EXAM | Verified Exam Questions and
Answers | Latest Updated Study Material 2026
Question:
critical period
Answer:
a specific time during an organism's life span
when it is most sensitive to environmental influences or stimulation; a specific phenomenon
must occur during a critical period or it won't happen at all (e.g., formation of certain organs
during the embryonic stage)
Question:
sensitive period
Answer:
stimulation and learning has more of an impact
during this period than it will at any other time (e.g., kids learn language most easily from age 1-
3 years but can still develop language later)
Question:
Klinefelter's syndrome
Answer:
occurs only in men and results from an
extra X chromosome (XXY); tend to be taller, less intelligent, have abnormal development of
secondary sex characteristics, and unable to have children
Question:
Turner's syndome
Answer:
occurs only in women and results from a
missing X chromosome (X0); normal intelligence but abnormal development of secondary
sexual characteristics (e.g., no menstruation, no ovulation)
Question:
Down syndrome
Answer:
trisomy 21; 3 chromosomes on chromosome
, 21; characterized by intellectual disability, broad skyll, physical deformities, and reduced activity
Question:
hemophilia
Answer:
sex-linked recessive disorder that causes excessive
bleeding; found predominantly in males; requires frequent transfusion of blood with clotting
factors
Question:
sickle-cell anemia
Answer:
autosomal recessive disorder that occurs in
1/500 African Americans; results in deformed, fragile red blood cells that can clog blood vessels,
causing anemia, severe pain, stunted growth, and frequent infections
Question:
germinal period
Answer:
stage 1 of prenatal period; conception until 2
weeks; zygote rapidly divides and ultimately implants itself onto the uterus wall
Question:
embryonic period
Answer:
stage 2 of prenatal period; 2 weeks until 8-12
weeks; start and rapid development of major organ systems and structures; embryo is most
vulnerable to teratogenic agents in the first 8-12 weeks
Question:
fetal period
Answer:
3rd stage of prenatal period; 8-12 weeks until birth;
rapid growth, with organs and other systems developing more complexity
