Reflecting on Piaget’s Theory

Piaget’s stage theory has been influential

globally, validating a number of ideas regarding

growth and development in many cultures and

societies. However, today’s researchers believe

the following:

1. Development is a continuous process.

2. Children express their mental abilities and

operations at an earlier age.

3. Formal logic is a smaller part of cognition.
