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 understand new information, we are engaging in cognitive activities. Cognitive skills are essential for everyday tasks, such as reading a book or solving a math problem. They help us interpret our surroundings and interact with others. For example, when we recognize a friend's face or recall a favorite memory, we are using our cognitive abilities to navigate the world around us.
