"Working Memory: Theories, Models, and Controversies"

Working memory refers to the brain’s ability to temporarily hold and manipulate information needed for tasks like reasoning or learning. Several theories and models explain how it works, such as the idea that it’s made up of different components like a “central executive” (which directs attention) and “slave systems” for specific types of info (like sounds or visuals). Controversies exist over its exact structure and capacity, with some researchers debating whether it’s a single system or multiple specialized parts. Understanding working memory helps explain how we process complex information and how cognitive functions can be affected by aging or brain injury.
