PSY210 — DEVELOPMENTAL PSYCHOLOGY
PRACTICE EXAM | 200 QUESTIONS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
SECTION 1: INTRODUCTION TO DEVELOPMENTAL PSYCHOLOGY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
1. Developmental psychology is best defined as the scientific study of:
A. Mental disorders across the lifespan
B. How people change and remain the same from conception to death
C. Brain structure and its influence on personality
,D. Learning and memory in school-aged children
E. Social interactions in adult populations
Correct Answer: B. How people change and remain the same from
conception to death
EXPERT RATIONALE: Developmental psychology examines physical, cognitive,
and socioemotional changes and continuities across the entire lifespan — from
conception through death — not just childhood or a single domain.
2. Which of the following best represents the nature vs. nurture debate in
developmental psychology?
A. Whether cognitive or emotional development occurs first
B. Whether development is continuous or discontinuous
C. The relative contributions of genetics and environment to development
D. Whether early or late experiences shape personality more
E. The debate between Piaget and Vygotsky on learning
Correct Answer: C. The relative contributions of genetics and environment
to development
EXPERT RATIONALE: The nature vs. nurture debate concerns how much of
development is driven by biological inheritance (nature) versus environmental
experiences (nurture). Most modern theorists agree both interact dynamically.
,3. The idea that development proceeds through a fixed series of stages, each
qualitatively different from the last, reflects which view?
A. Continuity
B. Stability
C. Plasticity
D. Discontinuity
E. Maturation
Correct Answer: D. Discontinuity
EXPERT RATIONALE: Discontinuous development assumes development occurs
in distinct stages with qualitative differences between them — like a caterpillar
becoming a butterfly — as opposed to gradual, quantitative change.
4. Which developmental domain refers to growth in reasoning, memory,
language, and problem-solving?
A. Physical domain
B. Socioemotional domain
C. Moral domain
D. Cognitive domain
, E. Behavioral domain
Correct Answer: D. Cognitive domain
EXPERT RATIONALE: The cognitive domain encompasses all mental processes
including thinking, memory, language, attention, and problem-solving. The physical
domain covers bodily growth and the socioemotional domain covers relationships
and emotions.
5. A developmentalist who believes early experiences are more important
than later experiences holds which view?
A. Plasticity
B. Critical period determinism
C. Contextual relativism
D. Epigenetic primacy
E. Normative aging
Correct Answer: B. Critical period determinism
EXPERT RATIONALE: Critical period determinism holds that certain early
windows of development are particularly formative and irreversible — meaning
early experiences carry disproportionate weight over later experiences.
6. Lifespan development as a field emphasizes which of the following?
A. Development ends at adolescence
