SECTION 1: RESEARCH METHODS &
DEVELOPMENTAL THEORIES (Questions 1-25)
Q1. In a study of the behavioral adjustment of a
group of children placed in foster care, the children
were assessed once a year over a period of 10
years. This is an example of a ________ study.
A) Developmental
B) Cross-sectional
C) Longitudinal
D) Sequential
Answer: C
Rationale: A longitudinal study follows the same
group of participants over an extended period to
observe changes and development. This design is
ideal for seeing how foster care placement affects
children over time .

,Q2. What is the type of research in which a
developmentalist examines simultaneously the
amount of computer use and its impact on a
population of 4-year-olds, 6-year-olds and 8-year-
olds at the same point in time?
A) Cross-sectional
B) Developmental
C) Sequential
D) Longitudinal
Answer: A
Rationale: A cross-sectional study compares
different age groups (cohorts) at the same point in
time. This design is efficient because it does not
require waiting for participants to age, but it cannot
determine change at the individual level .
Q3. In _______, development is ____________,
with achievements at one level building on those
of previous levels.
A) Discontinuous change; distinct
2|Page
,B) Continuous change; gradual
C) Discontinuous change; gradual
D) Continuous change; distinct
Answer: B
Rationale: Continuous change views development
as a gradual process where skills build on each
other over time. This is contrasted with
discontinuous change, which sees development
occurring in distinct stages .
Q4. An investigator typically devises two different
conditions and then studies and compares the
outcomes of the participants exposed to those two
different conditions to see how the behavior is
affected. This is called a(n) _________.
A) Hypothesis
B) Experiment
C) Treatment
D) Theory
Answer: B
3|Page
, Rationale: An experiment involves the manipulation
of one variable (the independent variable) to
determine its effect on another variable (the
dependent variable) .
Q5. A researcher working with college-age football
players is conducting a longitudinal study to
examine an athlete's decline in on-the-field
performance as the athlete ages. What type of
development would the researcher most likely be
studying?
A) Cognitive
B) Social
C) Personality
D) PhysicaL
Answer: D
Rationale: The decline in physical performance,
such as stamina or strength, is a subject of physical
development research .
