Watch the full video walkthrough above, then test yourself on the twenty questions below. Each one is explained on the video, including why the wrong answers trap most test-takers.

Questions 1 to 5 (questions 1 to 5)

1. A psychologist follows the same group of children every year from age five to age fifteen, testing them again and again. This research design is called: A Longitudinal Study. A longitudinal study follows the same people over a long stretch of time. Because it tracks one group as it ages, it can show how individuals actually change, which a one-time snapshot cannot.

2. The debate over how much of development is driven by genes versus by experience and environment is known as the question of: Nature Versus Nurture. Nature versus nurture asks how much of who we become is set by our inherited biology and how much is shaped by our surroundings. Most modern researchers conclude that the two work together.

3. According to Sigmund Freud, the part of the personality that operates on the pleasure principle and demands immediate gratification is the: Id. Freud's id is the primitive, unconscious drive for immediate pleasure. The ego works to satisfy it realistically, and the superego adds the moral conscience that holds it in check.

4. Erik Erikson believed that the central psychosocial conflict of adolescence is: Identity Versus Role Confusion. Erikson placed identity versus role confusion in the teenage years. Adolescents work to answer who they are, and resolving it well produces a stable sense of self and direction.

5. A researcher finds that children who watch more violent television tend to behave more aggressively, but cannot conclude that the television causes the aggression. This is because: Correlation Does Not Prove Causation. A correlation only shows that two things move together. Some third factor could drive both, so a relationship alone never proves that one variable causes the other.

Questions 6 to 10 (questions 6 to 10)

6. A substance such as alcohol that can cross the placenta and harm a developing fetus is called a: Teratogen. A teratogen is any agent, like alcohol, certain drugs, or some infections, that can damage a fetus during pregnancy. Prenatal alcohol exposure is a leading preventable cause of birth defects.

7. The grasping reflex, in which a newborn automatically curls its fingers around anything that touches its palm, is an example of: An Inborn Reflex Present at Birth. Newborns arrive with automatic, unlearned reflexes such as grasping, rooting, and sucking. These reflexes are present at birth and many fade during the first months as the brain matures.

8. In Harry Harlow's experiments, infant monkeys separated from their mothers preferred a soft cloth surrogate over a wire surrogate that provided food. The findings suggest that attachment is driven mainly by: The Comfort of Physical Contact. Harlow's monkeys clung to the cloth mother even though the wire mother fed them. This showed that the comfort of contact, not just feeding, is central to forming an attachment bond.

9. An infant who explores happily when a caregiver is present, becomes upset when the caregiver leaves, and is quickly soothed on the caregiver's return is showing what Mary Ainsworth called: Secure Attachment. In Ainsworth's Strange Situation, the securely attached infant uses the caregiver as a safe base, protests at separation, and is comforted on reunion. It is the most common and healthiest pattern.

10. A baby is shown a toy, then the toy is hidden under a blanket. A young infant who has not yet developed object permanence will: Act as If the Toy No Longer Exists. Before object permanence develops, out of sight truly means out of mind. The infant does not search for the hidden toy because, to that baby, the toy has simply stopped existing.

Questions 11 to 15 (questions 11 to 15)

11. Jean Piaget called the stage of cognitive development from birth to about age two, when babies learn through their senses and movements, the: Sensorimotor Stage. In Piaget's sensorimotor stage, infants understand the world through looking, touching, and moving. The major achievement of this stage is object permanence.

12. A four-year-old insists that a tall thin glass holds more juice than a short wide glass, even after watching the same juice poured between them. According to Piaget, this child has not yet mastered: Conservation. Conservation is the understanding that quantity stays the same despite changes in shape or arrangement. Preoperational children lack it, so taller looks like more even when the amount is equal.

13. Lev Vygotsky's term for the gap between what a child can do alone and what the child can do with help from a more skilled person is the: Zone of Proximal Development. Vygotsky's zone of proximal development is the sweet spot just beyond a child's solo ability, where guidance from a teacher or peer lets the child succeed and learn.

14. The temporary support a parent or teacher provides to help a child accomplish a task just beyond the child's current ability, then gradually withdraws, is called: Scaffolding. Scaffolding is the adjustable help a more skilled person gives within the zone of proximal development. As the child grows more capable, the support is slowly removed.

15. Noam Chomsky proposed that humans are born with a built-in capacity for acquiring language, which he called the: Language Acquisition Device. Chomsky argued that the human brain comes wired for grammar through what he called a language acquisition device. It helps explain how young children master language so quickly and similarly.

Questions 16 to 20 (questions 16 to 20)

16. In Diana Baumrind's research, parents who are both highly warm and highly demanding, setting clear rules while staying responsive to their children, use the parenting style called: Authoritative. Authoritative parents pair firm, consistent limits with warmth and open communication. This balanced style is linked to the best outcomes, including higher self-esteem and stronger social skills.

17. In Lawrence Kohlberg's theory of moral development, a young child who decides that an act is wrong mainly because it leads to punishment is reasoning at the: Preconventional Level. At Kohlberg's preconventional level, right and wrong are judged by rewards and punishments. Avoiding punishment, not principle or social approval, drives the child's moral choices.

18. According to Erik Erikson, the central psychosocial task of late adulthood, looking back on one's life with either satisfaction or regret, is the conflict of: Integrity Versus Despair. Erikson's final stage, integrity versus despair, is about reviewing one's life. A sense that it was meaningful brings integrity, while deep regret brings despair.

19. Elisabeth Kubler-Ross described five common responses to dying. The stage in which a person refuses to accept the diagnosis, insisting there must be a mistake, is: Denial. Kubler-Ross listed denial, anger, bargaining, depression, and acceptance. Denial often comes first, as the person resists believing the diagnosis is real.

20. Research on adulthood distinguishes two kinds of intelligence. The type that involves accumulated knowledge, vocabulary, and facts, and that tends to hold steady or even rise with age, is called: Crystallized Intelligence. Crystallized intelligence is the store of knowledge and verbal skill built up over a lifetime, and it stays stable or grows in later years. Fluid intelligence, the speed of solving novel problems, tends to decline.

What to do with your score

The point of twenty questions is not the twenty, it is the pattern. Mark which topic each miss came from, then spend your next session on that topic alone. None of it requires starting over, only tightening the spots that cost you points.

A single twenty-question set is a snapshot, not a study plan. To pass with margin you need volume: enough questions, in the exam's format, with explanations that turn a wrong answer into a correction. That is what Flying Prep's CLEP Human Growth and Development practice is built for: every question explained, with a free trial before you decide.
