& ANSWERS
LIFE-SPAN HUMAN DEVELOPMENT — ORIGINAL PRACTICE QUESTIONS WITH
RATIONALES
1. Which theorist is most associated with the lifespan perspective, emphasizing
that development is lifelong, multidimensional, multidirectional, plastic,
multidisciplinary, and contextual?
A) Sigmund Freud
B) Jean Piaget
C) Paul Baltes
D) Erik Erikson
Correct Answer: C
Rationale: Paul Baltes is known for the lifespan perspective, which views development
as lifelong, multidimensional, multidirectional, plastic, multidisciplinary, and
contextual.
2. A researcher studies the same group of children from age 5 to age 15. This is an
example of which research design?
A) Cross-sectional
B) Longitudinal
, Page 2 of 24
C) Sequential
D) Correlational
Correct Answer: B
Rationale: Longitudinal research follows the same participants over time, allowing
researchers to observe developmental change within individuals.
3. Which of the following best describes a critical period in development?
A) A time when a specific experience must occur for development to proceed normally
B) A time when development slows down
C) A time when development is not affected by experience
D) A time when only physical growth occurs
Correct Answer: A
Rationale: A critical period is a limited time during which a particular experience or
stimulation is necessary for normal development to occur.
4. Which research method compares people of different ages at the same point in
time?
A) Longitudinal
B) Cross-sectional
C) Case study
D) Experimental
Correct Answer: B
Rationale: Cross-sectional research compares different age groups at one point in
time, but it cannot reveal individual developmental change.
5. Which of the following is an example of a cohort effect?
A) Individual differences in temperament
B) Differences between generations due to historical events
, Page 3 of 24
C) Changes within a person over time
D) Genetic influences on development
Correct Answer: B
Rationale: A cohort effect occurs when differences between age groups are due to
historical or cultural experiences rather than age alone.
6. The nature versus nurture debate focuses on which question?
A) Is development continuous or discontinuous?
B) To what extent is development influenced by genetics and environment?
C) Is development universal or context-specific?
D) Is development active or passive?
Correct Answer: B
Rationale: The nature–nurture debate concerns the relative contributions of heredity
(nature) and environment (nurture) to development.
7. Which of the following is an ethical requirement for research with human
participants?
A) Deception must always be used
B) Informed consent must be obtained
C) Participants must be paid
D) Data must be shared publicly
Correct Answer: B
Rationale: Informed consent ensures that participants understand the study and
voluntarily agree to participate, which is a fundamental ethical requirement.
SECTION 2: PRENATAL DEVELOPMENT & BIRTH (Questions 8–14)
8. Which prenatal stage is characterized by rapid cell division and implantation in
the uterine wall?
