DOMAIN 1: ISSUES, THEORIES & RESEARCH METHODS (CHAPTER 1)
Questions 1–60
---
,Question 1. Which of the following best describes the nature–nurture debate in
developmental psychology?
A) Nature refers exclusively to genetic inheritance, while nurture refers exclusively to
parenting
B) Nature refers to genetic and hereditary influences; nurture refers to environmental
influences
C) Nature is more important than nurture in all developmental domains
D) Nurture is more important than nature in all developmental domains
Answer: B
Explanation: Nature refers to genetic and hereditary influences; nurture refers to
environmental influences such as nutrition, family, education, culture, and historical
conditions. Contemporary developmental science rejects a simple either–or answer; genes
influence the range and probability of outcomes, while environments influence whether and
how genetic potentials are expressed.
---
Question 2. Which recurring issue in developmental psychology concerns whether
development is a smooth quantitative progression or involves qualitative reorganisation?
A) Nature and nurture
B) Continuity and discontinuity
C) Universal and context-specific development
D) Stability and plasticity
Answer: B
, Explanation: Continuous development is a smooth quantitative progression produced by
essentially similar processes over time. Discontinuous development involves qualitative
reorganisation, so different explanations or structures are needed at different points.
---
Question 3. A researcher measures the vocabulary size of 5-year-olds, 10-year-olds, and 15-
year-olds in a single testing session. Which research design is being used?
A) Longitudinal design
B) Sequential design
C) Cross-sectional design
D) Experimental design
Answer: C
Explanation: A cross-sectional study compares different age groups at one point in time.
Researchers measure participants of various ages simultaneously and infer developmental
change from the differences between groups.
---
Question 4. What is a major disadvantage of the cross-sectional research design?
A) It is time-consuming and expensive
B) It cannot track individual change over time and is vulnerable to cohort effects
C) It is subject to practice effects
D) It can only study one cohort
