How do secondary and tertiary circular reactions differ?

What will be an ideal response?

Secondary circular reactions are goal-directed behaviors. Over time, the child has
learned that certain behaviors cause environmental events. For example, a child may
have learned that pushing a button on a toy in her crib will cause it to make a beeping
noise. With tertiary circular reactions, the child is able to take knowledge of the
relationship between his/her actions and the environment and apply it to specific
situations. For example, if Sarah has learned that pushing a button on a toy causes
interesting noises, she may attempt to push buttons on other toys.
