Section 1: Human Development Theories Across the Lifespan
(Q1-14)
Q1. According to Piaget's theory of cognitive development, which characteristic is
most typical of children in the preoperational stage?
A. Systematic hypothesis testing and deductive reasoning
B. Egocentrism and difficulty understanding conservation
C. Abstract thinking and metacognition
D. Object permanence and goal-directed behavior
Rationale: The preoperational stage (ages 2-7) is characterized by egocentrism
(inability to see perspectives other than one's own) and lack of conservation
understanding (failure to recognize quantity remains constant despite appearance
changes). Formal operational involves abstract thinking; sensorimotor involves object
permanence; concrete operational involves logical operations with concrete objects.
Correct Answer: B
Q2. A 4-year-old child believes that a tall, thin glass contains more juice than a short,
wide glass, even when both contain the same amount. Which Piagetian concept does
this demonstrate?
A. Accommodation
B. Conservation
C. Lack of conservation
D. Decentration
Rationale: This classic "conservation of liquid" task demonstrates that the child has
not yet developed conservation—the understanding that quantity remains invariant
,despite changes in appearance. Preoperational children focus on one salient
dimension (height) rather than considering both height and width (lack of
decentration).
Correct Answer: C
Q3. According to Vygotsky, what is the "zone of proximal development" (ZPD)?
A. The range of tasks a learner can complete independently without assistance
B. The range of tasks a learner can complete with guidance from a more
knowledgeable other
C. The range of tasks that are too difficult for a learner even with assistance
D. The physical space where learning occurs
Rationale: Vygotsky's ZPD is the gap between what a learner can do independently
and what they can achieve with guidance from a more knowledgeable other (MKO).
Scaffolding within the ZPD promotes development. Tasks below the ZPD are
mastered; tasks above cannot yet be learned even with help.
Correct Answer: B
Q4. A teacher provides a student with sentence starters, graphic organizers, and
guided questions to help them write a persuasive essay. Which Vygotskian concept is
the teacher applying?
A. Discovery learning
B. Scaffolding
C. Equilibration
D. Assimilation
Rationale: Scaffolding involves providing temporary support structures (sentence
starters, graphic organizers, guided questions) that help learners accomplish tasks
within their ZPD. As competence develops, scaffolding is gradually removed.
Discovery learning is Piagetian; equilibration and assimilation are Piagetian cognitive
,processes.
Correct Answer: B
Q5. According to Erikson's psychosocial theory, which crisis characterizes
adolescence (ages 12-18)?
A. Trust vs. mistrust
B. Autonomy vs. shame and doubt
C. Identity vs. role confusion
D. Intimacy vs. isolation
Rationale: Erikson's fifth stage, identity vs. role confusion, occurs during
adolescence. The adolescent must develop a coherent sense of self and identity;
failure leads to confusion about roles and future direction. Trust vs. mistrust is
infancy; autonomy is toddlerhood; intimacy is young adulthood.
Correct Answer: C
Q6. A middle school teacher notices that students are increasingly concerned with
peer acceptance and social comparison. Which Eriksonian stage best explains this
behavior?
A. Industry vs. inferiority
B. Identity vs. role confusion
C. Intimacy vs. isolation
D. Generativity vs. stagnation
Rationale: During identity vs. role confusion, adolescents are preoccupied with peer
relationships, social comparison, and fitting in as they construct their identity. Peer
acceptance becomes paramount. Industry vs. inferiority (elementary age) focuses on
competence; intimacy is young adulthood; generativity is middle adulthood.
Correct Answer: B
, Q7. According to Kohlberg, a child who follows rules primarily to avoid punishment
and gain rewards is operating at which level of moral development?
A. Postconventional
B. Conventional
C. Preconventional
D. Principled
Rationale: Kohlberg's preconventional level (Stages 1-2) is characterized by moral
reasoning based on avoiding punishment (Stage 1: obedience) and seeking
rewards/self-interest (Stage 2: individualism). Conventional level involves social
norms and authority; postconventional involves abstract principles and universal
ethics.
Correct Answer: C
Q8. A teenager argues that laws should be disobeyed when they violate fundamental
human rights. Which Kohlberg stage does this represent?
A. Stage 3: Good interpersonal relationships
B. Stage 4: Maintaining social order
C. Stage 5: Social contract and individual rights
D. Stage 6: Universal ethical principles
Rationale: Stage 5 (social contract orientation) recognizes that laws are social
contracts that can be changed when they do not serve collective welfare or individual
rights. Stage 6 (universal ethical principles) is even more abstract, based on self-
chosen universal principles of justice. The scenario fits Stage 5 most precisely.
Correct Answer: C
Q9. According to Bronfenbrenner's ecological systems theory, which system includes
the child's immediate settings such as family, school, and peer group?
A. Macrosystem
B. Exosystem
