Answer:
This is an example of Centration.
Explanation:
Centration is a term used in developmental psychology, specifically when using Piaget's theory of cognitive development. According to this theory children go through different stages of cognitive development and these are linked to the child's age. From ages 4 to 7, children are in the preoperational stage, and centration is a process that presents itself in this stage. It is the children's tendency to focus only on one salient aspect of a problem, situation or object. One of the most common aspects young children who are in this stage of cognitive development focus on is on the space an object occupies, for example, size or length.
In this case Eliza doesn't focus on the number of buttons in each row. Even though she knows that 10 is more than 8, when put in two different rows, she only focuses on the length of both rows, and because the one with 8 buttons is longer, she will inevitably choose that one.
