Veruca has not yet mastered concrete logic, which means she is probably in the preoperational stage of cognitive development.

Explanation:

The preoperational stage occurs in children between the ages of 2 and 7. Children begin to learn to manipulate symbols as well as develop their language skills. This is a major sign of development at this stage.

At this stage, children have not mastered concrete logic and cannot manipulate information mentally yet. Their points of view therefore, is the only information they can process. le play is also a common occurrence at this stage.
