Cognitive abilities refer to the mental skills that help us think, learn, and understand the world around us. These abilities include processes like memory, problem-solving, attention, and reasoning. They allow us to process information, make decisions, and adapt to new situations. People use their cognitive abilities every day, whether they are solving a math problem, remembering a friend's birthday, or planning a trip. These skills can vary from person to person and can be improved with practice and experience. Engaging in activities like reading, puzzles, or learning new things can help enhance our cognitive abilities over time.
