DEVELOPMENTAL PSYCHOLOGY— INFANCY AND
CHILDHOOD EXAM WITH VERIFIED ANSWERS DETAILED
RATIONALES GRADED A+
Complete Test Bank: Developmental Psychology — Infancy and Childhood
SECTION 1: INTRODUCTION TO DEVELOPMENTAL PSYCHOLOGY & RESEARCH STRATEGIES
(Questions 1–25)
1. Which of the following best describes the field of developmental psychology as defined by
Shaffer and colleagues?
A. The study of childhood disorders and their treatment
B. The study of systematic continuities and changes in individuals from conception to death
C. The study of how children acquire language
D. The study of genetic influences on behaviour
Rationale: Developmental psychology is defined as the study of systematic continuities and
changes in the individual that occur between conception and death. It encompasses physical,
cognitive, and social-emotional development across the lifespan.
2. Which of the following best describes "normative development" in developmental
psychology?
A. The study of individual differences in development
B. The typical or average patterns of change that characterize most individuals
1|Page
,Page 2 of 76
C. The study of abnormal development
D. The study of genetic disorders
Rationale: Normative development refers to the typical patterns of change that characterize
most individuals, such as the average age at which children begin to walk or speak their first
words. It contrasts with ideographic development, which focuses on individual variations.
3. A researcher who studies how a particular child's temperament changes over time is
engaging in which type of developmental inquiry?
A. Normative development
B. Ideographic development
C. Cross-sectional research
D. Epidemiological research
Rationale: Ideographic development focuses on individual variations in development, examining
how a specific individual changes over time. Normative development, by contrast, examines
typical patterns across groups.
4. Which of the following is a key advantage of the longitudinal research design?
A. It is less time-consuming than cross-sectional designs
B. It allows researchers to observe individual patterns of change over time
C. It eliminates the possibility of practice effects
D. It requires fewer participants than cross-sectional designs
Rationale: Longitudinal designs follow the same individuals over time, allowing researchers to
observe individual patterns of change and stability. They are time-consuming but provide
valuable data on developmental trajectories.
5. Which of the following is a limitation of the cross-sectional research design?
A. It cannot identify age differences
B. It is susceptible to cohort effects
2|Page
,Page 3 of 76
C. It requires following participants for many years
D. It cannot be used with children
Rationale: Cross-sectional designs compare different age groups at the same time, which can
confound age differences with cohort effects (differences due to the historical period in which
participants were born).
6. What is the primary purpose of the sequential research design?
A. To combine cross-sectional and longitudinal approaches
B. To study only one age group
C. To eliminate all confounding variables
D. To study genetic influences only
Rationale: The sequential design combines cross-sectional and longitudinal elements, allowing
researchers to examine both age effects and cohort effects while studying multiple cohorts over
time.
7. Which of the following best describes the "nature vs. nurture" debate in developmental
psychology?
A. The debate over whether development is influenced more by genetics or environment
B. The debate over whether development is continuous or discontinuous
C. The debate over whether development is universal or context-specific
D. The debate over whether development is active or passive
Rationale: The nature vs. nurture debate concerns the relative contributions of biological
inheritance (nature) and environmental influences (nurture) to development. Most
developmentalists now recognize that both interact to shape development.
8. A researcher who believes that development occurs in distinct stages, like a staircase, is
endorsing which view of development?
A. Continuous development
B. Discontinuous development
3|Page
, Page 4 of 76
C. Normative development
D. Ideographic development
Rationale: Discontinuous development views development as occurring in distinct, qualitatively
different stages, like a staircase. Continuous development, by contrast, views development as a
gradual, cumulative process, like a ramp.
9. Which of the following is an example of a "critical period" in development?
A. Learning to ride a bicycle
B. Language acquisition in early childhood
C. Developing a preference for certain foods
D. Learning to play a musical instrument
Rationale: A critical period is a specific time during development when an organism is
particularly sensitive to certain environmental influences. Language acquisition in early
childhood is considered a critical period, as children who do not acquire language during this
time may never fully develop language skills.
10. Which research method involves observing behaviour in a natural setting without any
manipulation?
A. Experimental research
B. Naturalistic observation
C. Correlational research
D. Survey research
Rationale: Naturalistic observation involves observing behaviour in its natural setting without
any manipulation by the researcher. It provides ecologically valid data but does not allow causal
conclusions.
11. Which of the following is a key advantage of the experimental method in developmental
research?
