Piaget's Theory of Cognitive Development Questions and Answers

Answer: C

A child who can reason logically about concrete events, classify objects into sets and carry out reversible mental operations is in Piaget's concrete operational stage, from about 7 to 11 years. The preoperational child cannot yet do reversible operations, the sensorimotor child learns through senses and movement, and the formal operational stage brings abstract and hypothetical thinking.

Piaget gives the concrete operational stage as roughly seven to eleven years, in which conservation, classification and seriation are mastered but only for concrete objects.

Answer: C

The formal operational stage of Piaget's theory begins at about 11 years and extends to about 15 years. Birth to 2 years is the sensorimotor stage, 2 to 7 the preoperational stage, and 7 to 11 the concrete operational stage. Piaget's formal operational stage is marked by abstract and hypothetical thinking, as in solving problems in science and mathematics.

Answer: A

Piaget described cognitive development as occurring in four qualitatively different stages.

The four stages are sensorimotor (birth to about 2 years), preoperational (about 2 to 7), concrete operational (about 7 to 11) and formal operational (11 onwards). Each stage is a different kind of thinking, not just more of the same, which is why they are called qualitatively different.

Eight stages resolved through conflict are Erik Erikson's psychosocial stages. Three levels belong to Kohlberg's theory of moral development. A continuous process from birth to adulthood is the opposite of a stage theory.
