Physical, Cognitive, and Socioemotional Development in Infancy 4

Imagine that you are working alongside Piaget and conducting research on cognitive development in infancy. You are observing 20-month old infant Sara Elizabeth. On the second day of your observation, you stack three colorful blocks, one on top of the other and knock them down, repeating this several times. Identify and describe the internalization of schemes substage as defined by Piaget. Provide an example of what you should expect to see and observe Sara Elizabeth do the next day.
