What is the main achievement during the third stage of the cognitive model?

The main achievement during the third stage of the cognitive model, often associated with Piaget's theory of cognitive development, is the development of logical thinking skills. This stage, known as the Concrete Operational Stage, typically occurs between the ages of 7 and 11. During this time, children begin to think logically about concrete events and understand the concept of conservation, which means they can recognize that quantity doesn't change even when its shape does.

Logical thinking skills enable children to solve problems in a more systematic way. They start to categorize objects, understand the concept of time, and can perform operations that involve reversing their thought processes. This cognitive leap allows them to manipulate objects mentally and think about the relationships between different elements logically, laying the foundation for more advanced reasoning skills they will develop in later stages.

The other choices, while relevant to various developmental aspects, do not capture the primary focus of this stage. Gaining sensory experiences is more characteristic of earlier stages, particularly the Sensorimotor Stage. Understanding abstract concepts typically develops later, in the Formal Operational Stage, where adolescents can think more hypothetically and abstractly. Improving social communication is an important aspect of overall development, but it does not specifically pertain to the cognitive achievements emphasized in this particular stage of Pi
