Chapter 1: The Study of Human Development
1. The field of human development is considered to
be a science because it:
A. Focuses only on childhood.
B. Relies on empirical evidence and the
scientific method.
C. Is based on common sense and intuition.
D. Only studies abnormal behavior.
B. Relies on empirical evidence and the scientific
method.
*Rationale: Human development is a scientific
discipline because it uses systematic observation,
experimentation, and data analysis to understand
how and why people change over time. *
, 2. Dr. Garcia is studying how children's problem-
solving skills change as they get older. She is
most likely interested in which domain of
development?
A. Physical
B. Cognitive
C. Psychosocial
D. Biological
B. Cognitive
*Rationale: The cognitive domain of development
encompasses mental processes such as learning,
memory, problem-solving, and intelligence. *
3. A researcher who believes that development is
primarily influenced by genetics and biological
maturation is emphasizing the role of:
A. Nurture
B. Nature
C. Continuity
D. Plasticity
B. Nature
*Rationale: The nature side of the nature-
nurture debate emphasizes the influence of
,genetic inheritance and biological factors on
development. *
4. The concept of "plasticity" in development
refers to the:
A. Idea that development is a smooth,
continuous process.
B. Potential for change and modification at all
stages of life.
C. Belief that early experiences are the sole
determinant of later outcomes.
D. View that development happens in distinct,
discontinuous stages.
B. Potential for change and modification at all

experience. It suggests that individuals are not
fixed at birth and can adapt and change
throughout their lifespan. *

normative age-graded influence?
A. The death of a parent during childhood.
, B. The impact of a global pandemic.
C. Puberty.
D. Winning the lottery.
C. Puberty.
*Rationale: Normative age-graded influences are
biological and environmental events that are
highly similar for people in a particular age
group. Puberty is a universal, biological event
tied to a specific age range. *
6. A researcher is interested in studying the effect
of a new teaching method on math scores. She
randomly assigns students to either the new
method or the traditional method. This is an
example of a(n):
A. Correlational study.
B. Case study.
C. Experiment.
D. Naturalistic observation.
C. Experiment.
*Rationale: An experiment is a research method
in which the researcher manipulates an
independent variable (teaching method) to
