Answer:
Preoperational Stage of Cognitive Development
Step-by-step explanation:
The name of this stage suggests what’s happening here: “Operational” refers to the ability to manipulate information logically. Although children think, but they can’t yet use logic to alter, integrate, or differentiate ideas. So they’re “pre” operational. They’re learning about the world by experiencing it, but they’re not yet able to manipulate the information that they’ve learned. The preoperational stage is the second stage in Piaget's theory of cognitive development. This stage starts about the age two, as children start to talk, and lasts until around age seven. During this period, children are thinking at a symbolic level (children use symbols to represent words, images, and ideas). The child's thinking during this stage is pre (before) operations i.e the child cannot use logic or transform, combine or separate ideas. During this stage, children begin to engage in symbolic play and learn to manipulate symbols. Obviously Mark is in the preoperational stage because the fact that his mother divdied his one half of sandwich into two for him, he feels happy thinking he and his helder sisiter now has the same number of sandwich.
