A cognitive module is a set of skills or abilities that help us understand and react to the world around us. It helps us learn, think, remember, and make decisions. Your cognitive module is like having your own personal set of tools to help you understand and interact with the world. Cognitive modules help us do things like recognizing faces, solving math problems, and remembering important information. When we are learning something new, we rely on our cognitive module to help us process that information.
