Three-Year-Olds Were Shown Pictures of Blue Cars, Red Cars, Blue

Three-year-olds were shown pictures of blue cars, red cars, blue flowers, and red flowers. They were asked to sort the pictures into a stack of blue things and a stack of red things. They performed very well on this task. They were then asked to sort the same cards again, but this time they should make a stack of cars and a stack of flowers. What is the likely outcome?

A) Three-year-olds should be able to successfully sort the cards into a stack of cars and a stack of flowers.
B) Because of their limited conceptual ability, three-year-olds will not be able to distinguish between cars and flowers, and both stacks will be a mixture of cars and flowers.
C) Three-year-olds will probably repeat what they did before; they will sort the cards into blue things and red things.
D) Three-year-olds will ignore the directions and will make four stacks (blue cars, red cars, blue flowers, and red flowers) .
