Cognitive development refers to the process by which individuals acquire, process, and utilize knowledge and skills throughout their lives. This development involves various mental functions, including thinking, problem-solving, memory, and language. It is influenced by both genetic factors and environmental experiences, such as education and social interactions. The study of cognitive development is often associated with psychologists like Jean Piaget, who proposed stages of cognitive growth in children. These stages illustrate how children's thinking evolves from simple to more complex forms as they interact with their surroundings. Understanding cognitive development helps in creating effective educational strategies and supporting learning at different ages.
