Final Answer:
The Concrete Operational Stage, occurring between 7 to 12 years, is a developmental phase in Piaget's theory where children acquire the ability to think logically about concrete events and objects.
Step-by-step explanation:
During the Concrete Operational Stage, children exhibit cognitive advancements marked by the ability to understand conservation (that quantity remains the same despite changes in appearance), engage in classification and seriation tasks, and grasp the concept of reversibility. Logical thought becomes more evident, allowing them to solve problems systematically. However, abstract thinking is still limited, as it primarily revolves around tangible, real-world experiences. This stage represents a crucial step in cognitive development, laying the foundation for more complex reasoning in adolescence.
Option:
The question does not provide multiple-choice options; it provides information about a stage in Piaget's theory.
