1. What is the PRIMARY definition of human development?
A) Physical growth only
B) Lifelong process of change across lifespan
C) Cognitive development only
D) Social development only
Answer: B
Rationale: Human development is a lifelong process involving physical, cognitive,
emotional, and social changes across the entire lifespan. Options A, C, and D focus
on only one aspect.
2. Which developmental period covers birth to 2 years?
A) Early childhood
B) Infancy
C) Toddlerhood
D) Prenatal period
Answer: B
Rationale: Infancy = birth to 2 years. Early childhood (A) = 2-6 years,
toddlerhood (C) = 1-3 years, prenatal (D) = before birth.
3. What is the DIFFERENCE between growth and development?
A) No difference
B) Growth = physical; Development = broader (physical, cognitive, emotional,
social)
C) Growth = mental; Development = physical
D) Growth = lifelong; Development = childhood only
Answer: B
Rationale: Growth refers specifically to physical changes (size, weight).
,Development includes ALL changes (physical, cognitive, emotional, social) across
lifespan.
4. Which characteristic BEST describes development?
A) Discontinuous
B) Continuous and sequential
C) Random
D) Only occurs in childhood
Answer: B
Rationale: Development is continuous (ongoing), sequential (predictable order),
and lifelong. It is not discontinuous (A), random (C), or only childhood (D).
5. What is "multidirectionality" in development?
A) Development moves in one direction
B) Some abilities improve while others decline
C) Development stops at adulthood
D) All abilities improve equally
Answer: B
Rationale: Multidirectionality = some abilities improve (e.g., knowledge) while
others decline (e.g., processing speed) across lifespan. Not one direction (A),
doesn't stop (C), not all improve equally (D).
6. Which age range defines "early adulthood"?
A) 0-12 years
B) 13-19 years
C) 20-40 years
D) 40-65 years
Answer: C

, 7. What is the PRIMARY focus of "developmental psychology"?
A) Mental disorders
B) Lifespan changes in behavior and mental processes
C) Brain structure only
D) Childhood only
Answer: B
Rationale: Developmental psychology focuses on lifespan changes in behavior,
cognition, and mental processes. Mental disorders (A) = clinical psychology, brain
only (C) = neuroscience, childhood only (D) = incorrect.
8. Which concept refers to "stable" traits across lifespan?
A) Continuity
B) Discontinuity
C) Plasticity
D) Multidirectionality
Answer: A
Rationale: Continuity = stable traits/patterns across lifespan. Discontinuity (B) =
stage-like changes, plasticity (C) = capacity for change, multidirectionality (D) =
some improve, some decline.
9. What is "plasticity" in development?
A) Inability to change
B) Capacity for change throughout life
C) Physical flexibility only
D) Only occurs in childhood
Answer: B
Rationale: Plasticity = brain's and behavior's capacity to change throughout life.
Not inability (A), not physical only (C), not childhood only (D).
10. Which developmental理论的 perspective emphasizes "unconscious
drives"?
A) Cognitive
