Chimpanzees are able to make judgements on whether two quantities of liquid are the same or different, and they are able to conserve correctly when liquids are transformed based on inferences.
Symbolic play also evolves at this stage allowing the child to engage in pretend play using available objects to represent something else, such as a spoon being waved in the air to represent an airplane. They are predictable and may be useful with developing communication. Piaget proposed that children's inability to conserve is due to weakness in the way children think during the preoperational stage ages 2—6. Jean Piaget was a Swiss developmental psychologist who studied children in the early 20th century. Piaget classrooms are more teacher-directed with a focus on routine, though there is flexibility and opportunity for child-directed activities. The child's concept of the world.
He sued four model cows, three of them black, and one white. . In addition to mastering some aspects of conservation, the child acquires greater proficiency at tasks that require logical reasoning, distinguishing facts from fantasies, classification of objects, deduction and induction, formulating judgments about cause and effect, spatial thought, seriation, and knowledge of numbers. By the time they are seven and at the end of the preoperational stage, though, they've learned not only to speak but to read and write. Lev Vygotsky developed his theory on child development at the same time Piaget was developing his own theory. A doll is then placed at various positions of the table. He gave them conservation of liquid tasks and spatial awareness tasks.
Being the second of the four, this stage appears at approximately 2 years of age and extends around 7 or so. Instead, it moved in leaps and bounds according to experiences. One of the experiments in which this feature can best be seen is in the conservation of mass. Being exposed to a variety of learning-by-doing experiences from a young age may help build up those internal index cards. He laid all the cows on their sides, as if they were sleeping.
However, if you ask which row has more, they will likely say that it is the one that makes the longer line, because they cannot simultaneously focus on both the length and the number.

Another well-known experiment involves demonstrating a child's understanding of conservation. A great deal of care is needed in cross-cultural examinations of conservation in order to avoid biasing results. As a child moves through the preoperational stage, she will begin to learn how to perform mental operations.
According to Piaget, at age 7 thinking is no longer egocentric, as the child can see more than their own point of view. However most children are not able to perform the conservation of number task correctly from ages 4—5, and most children develop the ability from ages 6—8.
