Cognition refers to the mental processes involved in gaining knowledge and understanding. This includes activities like thinking, learning, remembering, and problem-solving. When we use our brain to make decisions or solve puzzles, we are engaging in cognitive activities. Cognition is essential for everyday life, as it helps us navigate the world around us. For example, when we read a book or have a conversation, our cognitive skills allow us to interpret information and respond appropriately. Understanding cognition can improve our ability to learn and adapt, making it a vital aspect of human experience.
