Answer:
Mickey's type of thinking is C. Egocentric.
Step-by-step explanation:
According to Piaget, Mickey is the the Preoperational Stage of the Stages of Cognitive Development. This stage goes from 2- 7 years of age and, as the name states, occurs when the child is about to form an operational thinking.
A central point of this stage is egocentrism which refers to the inability to see outside one's point of view. A child during this stage drives him/ herself by imitating others and playing but he/she believes everyone sees the world through his/her eyes. For this child, the idea of a different point of view is impossible.
In this case, Mickey thought the frog was cool and since he was egocentric, he thought his mother would also think the frog was cool. It did not occur to Mickey that his mother could have a different opinion from his own or that she would not find it cool.
