Answers & Detailed Rationales | Verified &

Question 1
Which statement best reflects the lifespan perspective in
developmental psychology?
A. Most meaningful development occurs before adolescence.
B. Development is primarily determined by genetic maturation.
C. Development continues throughout life and involves multiple
interacting domains.
D. Cognitive development largely stops once adulthood begins.
Correct answer: C. Development continues throughout life
and involves multiple interacting domains.
Rationale: The lifespan perspective views development as
lifelong, multidimensional, multidirectional, and influenced by
biological, psychological, social, and cultural factors.
Development does not end with childhood or adolescence.
Genetic influences matter, but development results from
ongoing interactions between biological characteristics and
environmental experiences.
,Question 2
A researcher follows the same group of individuals from age 10
through age 40, assessing their reasoning abilities every five
years. Which research design is being used?
A. Cross-sectional
B. Longitudinal
C. Experimental
D. Meta-analytic
Correct answer: B. Longitudinal
Rationale: A longitudinal study repeatedly measures the same
individuals over an extended period. This allows researchers to
examine individual developmental trajectories and changes
within the same people. A cross-sectional design would
compare different age groups at one point in time.
Question 3
A study compares 10-, 20-, 40-, and 70-year-olds on memory
performance during the same month. What is the principal
advantage of this design?
A. It directly establishes developmental causation.
B. It eliminates all cohort effects.
C. It permits relatively rapid comparison of different age
groups.
D. It tracks individual change across decades.
,Correct answer: C. It permits relatively rapid comparison of
different age groups.
Rationale: Cross-sectional research compares different age
groups at approximately the same time and can therefore be
conducted relatively quickly. Its major limitation is that age
differences may reflect cohort differences rather than
developmental change. It does not track the same individuals
across time.
Question 4
Which example best illustrates the interaction of nature and
nurture?
A. A child inherits a gene associated with height but grows
differently depending on nutrition.
B. A person has genes and therefore cannot be influenced by
experience.
C. Environmental experiences affect behavior independently of
biology.
D. Development is either genetic or environmental, but never
both.
Correct answer: A. A child inherits a gene associated with
height but grows differently depending on nutrition.
Rationale: Development reflects continuous interaction
between biological predispositions and environmental
, conditions. Genetic potential may influence a characteristic,
while nutrition and other environmental factors affect whether
and how that potential is expressed. Nature and nurture are
therefore not competing explanations that operate
independently.
Question 5
Which statement most accurately describes maturation?
A. Learning produced exclusively through formal instruction
B. Developmental changes primarily associated with biological
growth and genetically guided processes
C. Any behavior learned through social reinforcement
D. Changes produced only by cultural expectations
Correct answer: B. Developmental changes primarily
associated with biological growth and genetically guided
processes
Rationale: Maturation refers to biologically based
developmental changes that unfold according to relatively
predictable patterns. Environmental experiences can influence
their timing and expression, but maturation is distinguished
from changes produced primarily through learning, training, or
social experience.
