QUESTIONS AND CORRECT ANSWERS
What are the three primary themes in developmental psychology? - CORRECT
ANSWER Nature and nurture, continuous and discontinuous stages, stability and
change.
What is the difference between cross-sectional and longitudinal studies? - CORRECT
ANSWER Cross-sectional studies examine different ages at once, while longitudinal
studies follow the same people over time.
What is the significance of the zygote stage in prenatal development? - CORRECT
ANSWER It is the foundation of all later development, and most miscarriages occur
here.
What is the significance of the embryo stage in prenatal development? - CORRECT
ANSWER It is most sensitive to teratogens, and organs begin forming.
What is the threshold of viability? - CORRECT ANSWER It is around 23 weeks, the
earliest survival outside the womb with medical help.
What factors influence prenatal development? - CORRECT ANSWER Teratogens,
environment, maternal illness, stress, diet, drug and alcohol use, and hormones.
What are some abilities of newborns? - CORRECT ANSWER Habituation and reflexes
such as grasping and rooting.
What does the visual cliff experiment test? - CORRECT ANSWER It tests depth
perception in infants.
What is maturation in development? - CORRECT ANSWER It is the biological growth
sequence largely independent of experience.
, What are critical/sensitive periods? - CORRECT ANSWER Windows when experience
has the strongest effect, such as in vision and language.
What did the Rosenzweig study reveal about cognitive development? - CORRECT
ANSWER Rats in enriched environments developed thicker cortexes, indicating
experience physically changes brain structure.
What is infantile amnesia? - CORRECT ANSWER It prevents long-term recall before
age ~3 due to immature hippocampus and language limits.
What is adolescence? - CORRECT ANSWER The transition from childhood to
adulthood.
What is puberty? - CORRECT ANSWER The sexual maturation process.
What is a growth spurt? - CORRECT ANSWER A rapid height and weight increase
during puberty due to hormonal changes.
What neuroscientific argument explains teenage impulsivity? - CORRECT
ANSWER The limbic system matures before the prefrontal cortex, leading to emotions
overriding self-control.
What physical changes occur during middle and late adulthood? - CORRECT
ANSWER Muscle loss, stiff joints, decline in balance, menopause, and sensory
abilities decline.
How can exercise impact aging? - CORRECT ANSWER It preserves muscle, brain
blood flow, bone density, and slows cognitive decline.
What is the difference between gender and sex? - CORRECT ANSWER Sex refers to
biological anatomy, while gender refers to social and psychological identity.
