rose is sharing some cookies with her younger brother, george. she takes two cookies for herself and gives one to her brother
when george protests that she has more, rose breaks his cookie in half and returns it to his plate. both are happy with this
distribution. which stage of development is each child in?
rose: sensorimotor; george: sensorimotor
rose: preoperational; george: sensorimotor
rose: formal operational; george: concrete operational
rose: concrete operational. george: preoperational

Explanation:

Piaget's theory states that schemas grow and change through assimilation (fitting new info into existing schemas) and accommodation (adjusting schemas for new info). For the second question, in Piaget's stages, the pre - operational stage (2 - 7 years) lacks conservation (George is fooled by cookie break). The concrete operational stage (7 - 11 years) has conservation (Rose knows breaking doesn't change quantity).

Answer:

First question: assimilation and accommodation. Second question: Rose: concrete operational, George: preoperational.
