(true/false)

True.

Explanation:

According to Jean Piaget, conservation is a logical thinking skill that enables us to conclude that a specific quantity will stay the same notwithstanding changes in the package, form, or visible size.  

In Piaget´s psychological theory, this capacity doesn´t appear in the preoperational stage of their development (age 2 to 7). It develops in the concrete operational stage (age 7 to 11).
