Jonas knew that animals with fur, pointy ears, a tail, four legs, and that say "woof" are called "dogs" by his parents. He saw a new animal and thought it was a dog until it "meowed." Jonas's parents said this was a "cat." Jonas could now distinguish between dog and cat depending on the sound the animal made. This revision of Jonas's schema of a "dog" best illustrates:a. assimilation.
b. accommodation.
c. formal operations.
d. object permanence.
