Portage Learning PSYC 140 (PSYC140)
Developmental Lifespan Psychology Module
1 Exam Latest 2026.
This comprehensive examination assesses foundational knowledge in human lifespan
development, covering theoretical frameworks, research methodologies, genetic and
environmental influences, prenatal development, and birth processes. The 30 questions are
aligned with Portage Learning's PSYC 140 Module 1 curriculum and current developmental
psychology scholarship, testing both conceptual understanding and application of
developmental principles to real-world scenarios.
DOMAIN 1: LIFESPAN PERSPECTIVE & RESEARCH METHODS (Questions 1-6)
Q1 (Multiple Choice): According to Paul Baltes' principles of lifespan development, which
principle states that development is influenced by both historical events and the individual's
specific timing within history?
A. Multidirectionality
B. Plasticity
C. Historical context
D. Multicontextuality
Answer: C
Rationale: Historical context (also called historical embeddedness) recognizes that
development is shaped by the historical era in which a person lives. Events such as wars,
economic depressions, technological advances, and social movements affect developmental
trajectories differently depending on when individuals experience them during their lifespan.
Q2 (Multiple Choice): Which research design follows the same group of participants over an
extended period, repeatedly measuring the same variables to track developmental changes?
A. Cross-sectional design
B. Longitudinal design
C. Sequential design
D. Experimental design
, Answer: B
Rationale: Longitudinal research studies the same participants repeatedly over time, enabling
direct observation of individual developmental trajectories and within-person change. This
design is powerful for tracking stability and change but is time-consuming, expensive, and
vulnerable to participant attrition (dropout) over extended periods.
Q3 (Multiple Choice): A researcher compares 5-year-olds, 10-year-olds, and 15-year-olds on
working memory performance in a single study conducted in 2024. Which research design is
being used?
A. Longitudinal
B. Cross-sectional
C. Sequential
D. Case study
Answer: B
Rationale: Cross-sectional research compares different age groups (cohorts) at a single point
in time. While efficient and immune to attrition, this design confounds age differences with
cohort effects—differences due to growing up in different historical periods rather than
developmental change itself.
Q4 (Select All That Apply): Which of the following are advantages of longitudinal research
designs? (Select all that apply)
A. Can track individual developmental trajectories over time
B. Quick and inexpensive to conduct
C. Not affected by participant dropout
D. Can distinguish true developmental change from cohort effects
E. Efficient for comparing many age groups simultaneously
Answer: A, D
Rationale: Longitudinal designs uniquely track individual change trajectories and can separate
true age-related change from cohort effects by observing the same individuals mature. They
are not quick or inexpensive (B is incorrect), are highly affected by attrition (C is incorrect),
and do not efficiently compare many age groups simultaneously (E describes cross-sectional
advantages).
