Last month it was easy to take an annoying toy away from julia and give her another. now, however, julia cries desperately if you take her toy away and reaches and looks for it even though the toy is out of sight. 1. what cognitive changes have occurred? (use a piagetan term) 2. what stage of cognitive development is julia in?

The cognitive change that has occurred was from sensorimotor to preoperational. It is because in preoperational stage, a child will likely think the object to be more permanent or show value to it rather than sensorimotor in which the child doesn’t necessarily give any meaning or interest to a toy. Julia is in the second stage of Piaget’s theory in the cognitive development.
