SECTION ONE: QUESTIONS 1–100
1. A researcher is studying the same group of children at ages 5, 10, and 15 to track
changes in their social skills. Which research design is being utilized?
A. Cross-sectional
B. Longitudinal
C. Microgenetic
D. Sequential
🟢 B. Longitudinal
🔴 RATIONALE: A longitudinal design follows the same individuals over a period of time to
observe developmental changes and stability within the same cohort.
, 2. According to Piaget, a child who can perform conservation tasks but lacks the ability to
think abstractly is in which stage of cognitive development?
A. Sensorimotor
B. Preoperational
C. Concrete operational
D. Formal operational
🟢 C. Concrete operational
🔴 RATIONALE: During the concrete operational stage (ages 7–11), children develop logical
thinking about physical objects and master conservation, but they cannot yet manipulate abstract
or hypothetical concepts.
3. In Bronfenbrenner’s bioecological model, the interactions between a child's parents and
their teachers occur within the:
A. Microsystem
B. Mesosystem
C. Exosystem
D. Macrosystem
🟢 B. Mesosystem
🔴 RATIONALE: The mesosystem consists of the connections or relationships between different
microsystems, such as the home and the school environments.
4. Which of the following is an example of a fine motor skill?
A. Running
B. Jumping rope
C. Buttoning a shirt
D. Kicking a ball
🟢 C. Buttoning a shirt
🔴 RATIONALE: Fine motor skills involve the coordination of small muscle movements, typically

, 5. A newborn displays the rooting reflex when:
A. Their cheek is stroked
B. They are startled by a loud noise
C. Something is placed in their palm
D. The sole of their foot is touched
🟢 A. Their cheek is stroked
🔴 RATIONALE: The rooting reflex helps the infant find a food source; when the cheek is

6. According to Erikson, the primary developmental task of adolescence is:
A. Autonomy vs. Shame and Doubt
B. Initiative vs. Guilt
C. Identity vs. Role Confusion
D. Intimacy vs. Isolation
🟢 C. Identity vs. Role Confusion
🔴 RATIONALE: Adolescence is defined by the search for a sense of self and personal identity

7. Which teratogen is most commonly associated with low birth weight and increased risk of
Sudden Infant Death Syndrome (SIDS)?
A. Alcohol
B. Nicotine
C. Mercury
D. Caffeine
🟢 B. Nicotine
🔴 RATIONALE: Maternal smoking or exposure to nicotine constricts blood vessels and reduces
oxygen to the fetus, leading to growth retardation and respiratory complications.
8. Vygotsky’s concept of the Zone of Proximal Development (ZPD) refers to:
, A. The physical space required for healthy play
B. Tasks a child can do only with the help of a more skilled person
C. The biological limit of a child’s intelligence
D. Tasks that are too easy for a child to complete alone
🟢 B. Tasks a child can do only with the help of a more skilled person
🔴 RATIONALE: ZPD represents the range of tasks that are too difficult for a child to master
alone but can be learned with guidance and encouragement from a knowledgeable adult or peer.
9. An infant who is distressed when their caregiver leaves but is easily comforted upon their
return is demonstrating which attachment style?
A. Secure
B. Avoidant
C. Resistant
D. Disorganized
🟢 A. Secure
🔴 RATIONALE: Secure attachment is characterized by the child using the caregiver as a secure
base, showing distress at separation, and seeking contact upon reunion.
10. Which part of the brain is the last to fully develop, usually reaching maturity in early
adulthood?
A. Amygdala
B. Hippocampus
C. Prefrontal cortex
D. Occipital lobe
🟢 C. Prefrontal cortex
🔴 RATIONALE: The prefrontal cortex, responsible for executive functions like decision-making,
impulse control, and planning, does not finish myelinating until the mid-20s.
11. A child believes that the moon follows them when they walk at night. This is an example
