Question

The classic "conservation task" developed by Piaget involves two short containers that contain equal amounts of liquid. While a child watches, the water from one container is poured into a tall, thin beaker, and the child is asked, "Which beaker holds more water, the short container or the tall container?" Four-year-old Daniel answers the question incorrectly, while seven-year-old Emily is able to answer the question correctly. Why?a. Daniel is in preoperational stage, while Emily is in concrete operational stage. b. Girls progress through stages of cognitive development earlier and faster than boys. c. Emily is in formal operational stage, and Daniel is in concrete operational stage.d. Daniel is in sensorimotor stage, and Emily is in preoperational stage.

Answer 1

a. Daniel is in preoperational stage, while Emily is in concrete operational stage.

Step-by-step explanation:

Jean Piaget has given the theory of cognitive development in which he has mentioned four different stages including sensorimotor, preoperational, formal operational, and concrete operational.

Preoperational stage: This is the second stage in the theory which starts from the age of two and lasts through seven years of a child's age. in this stage, a child is involved in manipulating symbols and symbolic play.

Concrete operational stage: This is the third stage in the theory and starts from the age of seven and lasts through approximately eleven years of a child's age. In this stage, the child tends to develop logical and rational thoughts.
