The term "cognitive" refers to processes related to thinking, understanding, learning, and remembering. It involves how we perceive the world, solve problems, and make decisions. For example, when we learn a new skill, our cognitive abilities help us process information and apply it effectively. Cognitive functions are essential for everyday activities, such as reading a book or navigating a new city. They are influenced by various factors, including our experiences and environment. Researchers often study cognitive development in children to understand how they learn and grow, which can help improve educational methods and tools, like educational games and interactive apps.
