Introduction
This comprehensive final examination is designed to assess mastery of developmental lifespan
psychology across foundational, applied, and professional domains. It evaluates knowledge of
major theories, physical, cognitive, social, emotional, and moral development from conception
through late adulthood. The exam includes multiple-choice knowledge items and scenario-based
questions requiring interpretation, analysis, ethical reasoning, and professional judgment.
Emphasis is placed on real-world application, cultural responsiveness, legal compliance, safety,
and evidence-based decision-making. Successful completion demonstrates readiness to apply
developmental principles in clinical, educational, research, and community settings.
SECTION ONE – QUESTIONS 1–100
,Question 1
Which theorist is most closely associated with the psychosocial stages of development?
A. Jean Piaget
B. Erik Erikson
C. B.F. Skinner
D. John Bowlby
🟢 B. Erik Erikson
🔴 Explanation: Erikson proposed eight psychosocial stages across the lifespan, each defined
by a central crisis. Piaget focused on cognitive development, Skinner on behaviorism, and
Bowlby on attachment.
Question 2
A researcher observes that infants who are securely attached tend to explore more freely in the
presence of their caregiver. This best illustrates which concept?
A. Object permanence
B. Secure base
C. Conservation
D. Scaffolding
🟢 B. Secure base
🔴 Explanation: A secure base is the caregiver’s presence that allows an infant to explore
confidently. Object permanence and conservation are Piagetian concepts, and scaffolding is
Vygotskian.
Question 3
During which prenatal period does the neural tube form?
A. Germinal period
B. Embryonic period
C. Fetal period
D. Perinatal period
🟢 B. Embryonic period
🔴 Explanation: The neural tube develops during the embryonic period, typically between the
third and fourth weeks after conception. The germinal period precedes it, and the fetal period
follows.
Question 4
A 4-year-old believes that a tall, narrow glass contains more water than a short, wide glass
,even though both hold the same amount. This child has not yet developed:
A. Object permanence
B. Conservation
C. Egocentrism
D. Theory of mind
🟢 B. Conservation
🔴 Explanation: Conservation is the understanding that quantity remains the same despite
changes in appearance. This is a hallmark of Piaget’s preoperational stage limitation.
Question 5
Which attachment style is characterized by a child who shows little distress when the caregiver
leaves and avoids the caregiver upon return?
A. Secure
B. Avoidant
C. Ambivalent
D. Disorganized
🟢 B. Avoidant
🔴 Explanation: Avoidant attachment involves limited distress at separation and avoidance of
contact at reunion. Secure children seek comfort, ambivalent children show mixed reactions,
and disorganized children show confused behaviors.
Question 6
A school psychologist is evaluating a 7-year-old for possible ADHD. Which symptom must be
present before age 12 according to DSM-5 criteria?
A. Hyperactivity only
B. Inattention only
C. Several symptoms across settings
D. Symptoms only at home
🟢 C. Several symptoms across settings
🔴 Explanation: DSM-5 requires several symptoms present before age 12 and across multiple
settings. Symptoms limited to one setting or only one symptom type are insufficient.
Question 7
Vygotsky’s zone of proximal development refers to:
A. Tasks a child can do alone
B. Tasks a child cannot do at all
, C. Tasks a child can do with guidance
D. Tasks a child has mastered
🟢 C. Tasks a child can do with guidance
🔴 Explanation: The ZPD is the gap between what a learner can do independently and what
they can do with assistance. It emphasizes social interaction and scaffolding.
Question 8
Which teratogen is most strongly associated with fetal alcohol spectrum disorders?
A. Nicotine
B. Alcohol
C. Caffeine
D. Mercury
🟢 B. Alcohol
🔴 Explanation: Alcohol is a known teratogen causing fetal alcohol spectrum disorders,
including physical and cognitive impairments. Nicotine, caffeine, and mercury have other
effects but are not the primary cause of FASD.
Question 9
A 15-year-old argues that a rule should be changed because it is unfair to a minority group.
According to Kohlberg, this reflects which level of moral reasoning?
A. Preconventional
B. Conventional
C. Postconventional
D. Amoral
🟢 C. Postconventional
🔴 Explanation: Postconventional reasoning involves evaluating rules against universal ethical
principles and justice. Preconventional focuses on punishment and reward, and conventional
focuses on social approval and law and order.
Question 10
Which of the following is a primary characteristic of Piaget’s sensorimotor stage?
A. Abstract reasoning
B. Conservation
C. Object permanence
D. Hypothetical thinking
🟢 C. Object permanence
