Which features delineate the preoperational stage?

• A. 2 to 7; language development is occurring; child is egocentric; has difficulty taking another's point of view; classifies objects by one feature.
• B. 7 to 11; begins logical operations and understands conservation.
• C. Birth through 2; reflexive behaviors dominate.
• D. 11 to 15; abstract reasoning emerges.

Answer: (A)

In the preoperational stage children start using language and symbols to represent objects and experiences, but they don’t yet think logically about how things work. This period typically spans roughly ages two to seven. Language development is a clear feature, and you’ll also see egocentrism—difficulty seeing things from another person’s point of view—and centration, where thinking focuses on one perceptual feature at a time, so children may classify objects by just a single aspect. They often engage in imaginative play and symbolic thought, yet they struggle with reversible thinking and conserving quantity or amount when appearances change. The other descriptions describe later stages—concrete operational features like logical reasoning and understanding conservation (typically around seven to eleven), sensorimotor reflex-dominated behavior (birth to two), and abstract reasoning in adolescence (around eleven and up).
