Answer: According to Piaget, Dino demonstrated EGOCENTRISM when he did not turn the book to where his Mom could see.
Explanation:
Egocentrism
Children at their youngest age are more centered on themselves as individuals not concerned with everyone outside of that due to the fact that they haven't established the rules of society so their thoughts and communication still evolve around them. When a child is not able to see things in someone else's perspective but sees things only in their own perspective Piaget refers to this as egocentrism.
Piaget suggests that a child believes everyone sees, feel and hear things just like they do.
At this stage that when they would start to play next to others but not with them and even when they speak they don't speak with an intention to make a conversation.
At this stage Dino believes his mom will see the book the way he sees it hence he doesn't turn it to her.
The parents are the usual and appropriate surrogate decision makers for a newborn. The child was the product of their love so they should be the one to decide for the child. It could be inferred that they would be deciding for the betterment of the child because it is assumed that the parents love the child. Therefore, parents are the appropriate surrogate decision maker for a newborn except if proven otherwise.
