1. Which of the following stages are included in Jean Piaget’s theory of cognitive
development? (Select All That Apply)
A. Sensorimotor stage
B. Preoperational stage
C. Concrete operational stage
D. Formal operational stage
E. Post-conventional stage
F. Generativity stage
Correct Answer: A, B, C, D
Explanation: Jean Piaget proposed four distinct stages of cognitive development that
children progress through as they grow. The stages include sensorimotor, preoperational,
concrete operational, and formal operational. The post-conventional stage refers to
Kohlberg’s moral theory, while generativity is part of Erikson’s psychosocial theory.
2. In the context of prenatal development, which period lasts from conception until two
weeks and is characterized by rapid cell division?
A. The Embryonic stage
,B. The Germinal stage
C. The Fetal stage
D. The Zygotic transition
Correct Answer: B
Explanation: The germinal stage is the first phase of prenatal development, spanning the
first two weeks after fertilization. During this time, the zygote undergoes rapid mitotic
division as it travels toward the uterus for implantation. This phase is distinct from the
embryonic stage, which involves the formation of major organ systems.
3. According to Erik Erikson, the primary psychosocial conflict during infancy (birth to 1 year)
is:
A. Autonomy vs. Shame and Doubt
B. Trust vs. Mistrust
C. Initiative vs. Guilt
D. Industry vs. Inferiority
Correct Answer: B
Explanation: Erikson’s first stage of psychosocial development focuses on the infant’s
basic needs being met by parents. If the child receives consistent care, they develop a sense
of trust in the world. Failure to provide this care leads to a pervasive sense of mistrust and
anxiety.
, 4. A child who understands that the amount of liquid remains the same even when poured
into a differently shaped container has mastered which concept?
A. Object Permanence
B. Conservation
C. Reversibility
D. Egocentrism
Correct Answer: B
Explanation: Conservation is the understanding that physical properties do not change
despite changes in appearance or shape. Piaget observed that children usually acquire this
ability during the concrete operational stage. It requires the child to move beyond
centration and consider multiple dimensions of a stimulus.
5. Which of the following are considered teratogens that can adversely affect fetal
development? (Select All That Apply)
A. Alcohol
B. Nicotine
C. Prenatal vitamins
D. Cocaine
E. Radiation
